Hidden Ingredient In New, Greener Battery: A Virus

Scientists at MIT have developed a new, more environmentally and friendly way to make lithium batteries. Their approach employs an unusual component: genetically engineered viruses.

These new batteries have the same energy capacity as other lithium batteries of the same size and show potential to develop even more powerful batteries.MIT researcher Angela Belcher, who trained in biology, inorganic chemistry and electrical engineering, has long been interested in using natural biological processes to build better technology.A few years ago, Belcher began working on batteries. She wanted to find a material for electrodes ¡ª the positive and negatives ends of the battery ¡ª that would have the right electrical properties and could be assembled by a biological system o fPresario V3000 battery “We chose iron phosphate because lithium iron phosphate was already shown to be a good battery material,” says Belcher. “And also because biology has done a fantastic job with those elements.”

Iron and phosphate are already used by lots of biological systems. Red blood cells contain iron, and phosphate is an important ingredient in DNA.To make an electrode, Belcher and her team needed to assemble the iron and phosphate molecules into a scaffold. The biological system Belcher chose to do this was a virus.The viruses she used are long and skinny by nature. They attract iron and phosphate molecules along their length, which creates a stiff scaffolding. Belcher’s viruses can also hold tight to carbon nanotubes, whose length is thousands of times smaller than a pencil dot. Attaching a carbon nanotube to one end of the electrode allows electricity to flow in and out of the Dell GK479 battery. Belcher and her team published their work in the journal Science.

One advantage of using viruses is that if Belcher didn’t like any properties of the electrode, she just tweaked the DNA of the virus that was making it. In a sense, she was evolving her virus, which was evolving her electrode, so she could select the one that worked best of Acer Travelmate C300 battery Once you put enough of these virus-electrodes together, you can create a kind of biobattery that can power an LED light.”It’s fun, and it’s kind of cute, to power a green LED, but what about my laptop? What about my iPhone? What about my car?” says Belcher. “The power performance is there for us. Now it’s a matter of scale.”Achieving that scale should be doable, researchers say.

“It would be a different manufacturing process, but I think that there’s a very reasonable chance that the whole procedure would scale industrially,” says David Wright, a chemist at Vanderbilt University in Nashville.The new Dell gd761 battery already has properties that put it on a par with batteries being manufactured commercially today, Wright says. The researchers are hopeful that later versions of the battery could be used to power hybrid cars.And manufacturing this biobattery should take less energy and produce fewer pollutants, he adds. “This battery is made in water. It has no organic solvents in it, and the material is made in room temperature.”

About the Laptop-Battery Danger

Apple Computer announces it is recalling nearly 2 million notebook computer batteries that could overheat and catch fire. The batteries, like 4 million recalled by Dell, are made by the same supplier, Sony.For personal, noncommercial use only. See Terms of Use. For other uses, prior permission required.

The Apple Computer company is recalling nearly two million laptop batteries like Apple A1008 because of a fire hazard. The move comes just over a week after rival computer-maker Dell announced its own battery recall. Both companies used batteries manufactured by the Sony Corporation.

Apple’s recall of 1.8 million laptop batteries is the second biggest ever for a computer maker, topped only by Dell’s Dell GK479 last week that it would replace more than four million batteries.

Mr. SCOTT WOLFSON (Spokesman, Consumer Product Safety Commission): We have the same issue once again of overheating, of that fire hazard. So once again, consumers need to pay attention to this recall.HORSLEY: Sony spokesman, Rick Clancy, says the battery cells involved in both recalls were made at the same Sony factory in Japan. Sony also makes batteries Acer Travelmate C300 battery for other PC makers, but Clancy does not expect any more recalls.
According to the Consumer Product Safety Commission, batteries in at least six Dell laptops overheated or caught fire, causing some damage. The Commission’s Scott Wolfson said Apple heard complaints from nine customers,likePowerBook G4 15 battery, two of whom suffered minor burns. Professor Sadoway has been looking for a way to build safer lithium ion cells by replacing the volatile liquid center with a solid. Even though such research is important, he says, it’s not been terribly fashionable.

Laptop Battery ,how much do you know

The birth of the day from the laptop, the battery of this “servant” had been accompanied on its side, there is no battery, it can be said can not be called the laptop “mobile computer.” With the notebook performance and technology continues to improve with the improvement, it is the “servant” of the “quality” is also getting higher and higher, from the past, nickel-chromium batteries, nickel-metal hydride batteries to now have been using lithium batteries may be popular even after the fuel the battery, few people care about this and notebooks are closely related to what – the battery, then let me work with you to look into the laptop battery.

The classification and distinction between the battery In general we use there are three kinds of batteries, 1. Nickel-chromium batteries, 2. Ni-MH battery, 3. Lithium battery; they are generally expressed as: Ni-Cd NI-CD, Ni-MH NI-MH, Lithium-Ion battery LI, in recent years, In the notebook field has also been a fuel cell, its only by-product of water and heat, no noise, the basic pollution-free, efficient power generation systems in general higher than the multi-reach 43 ~ 58%, if the heat produced by the reaction utilization, efficiency can be up to 80%! Is a clean and environmentally friendly power. Because of Dell GK479 its technology was not perfect, there are still many problems to be solved, and now it is in terms of cost, size, weight, ease of access to fuel, both absolutely can not and traditional lithium batteries and polymer lithium battery to compete.

NI-CD Ni-Cd batteries because of their age is too early, so have many of the shortcomings of a headache, such as: bulky, heavy weight, capacity, small, short life, there is memory effect, etc. (useless), and now no longer in use. Now mainly NI-MH battery Ni-MH and LI lithium two kinds. Ni-MH battery which is also active in the battery industry, 1:00, compared to other batteries, nickel-metal hydride batteries to be more environmentally friendly some, it is also by far the most environmentally friendly battery,like Dell xps m1730 battery while the lithium battery Well, with a small size, light weight, large capacity, low memory effect, charging time is short, etc., well received by customers love, but you will often see the back of the battery properly abandoned and handling lithium batteries instructions? Because the lithium batteries to discard will cause environmental pollution.

Now, some people may be misunderstanding of lithium batteries, lithium batteries do not remember that, in fact, lithium is not without memory, but only relatively small memory, it seems not very clear. And lithium batteries can be divided into lithium and lithium-ion battery two kinds. Lithium-Ion battery will have a long time ago, and it is not safe when used often in charge when burning, bursting, perhaps because of the sake of lithium element too active. Then there is an improved lithium-ion batteries, lithium can inhibit the added element of active ingredients, so that lithium really a safe, efficient, convenient, while the older Lithium-Ion battery also will be eliminated.more like Vaio VGN-SZ battery As to how to distinguish them from the battery’s label will be able to identify, lithium battery for LI, lithium-ion battery LI-ION.

Now that the market price of the original equipment batteries are very expensive, generally place around 1000-1500, so some of my friends started to replace the battery, through their own batteries to achieve the purpose of extending battery life. Theory should, it is possible, but due process reasons, the Presario V3000 battery batteries are generally used ultrasonic welding, there is no gap, it is difficult apart, even if the hardware is also very difficult to disassemble a close, I see the electronic Shangyuan to the two hands are their own battery replacement batteries and then sell finished, the battery can be a combination of Office, it is clear to see there are 502 marks, after gluing, even with batteries, replace more time to find a match difficult.

E-funded, respectively 80% and 20%. The total project headed by Dr. Gao Xiaoping.

According to Green Mountain in-house staff said the company’s core team named Tang Xiaoxia Gao calm and a Deputy Director. Dr. Gao Xiaoping is the returnees for sony battery, with strong technical strength and experience. Tang Xiaoxia is the local people, worked as a teacher, and later transferred to Hoi Economic Zone, and is not rich in the semiconductor experience.

A former employee has said that because the project Sony VGP-BPS8 Battery slower than expected, so the company of staff and other cost control is very strict, “Sometimes it will adopt some method of job cuts in disguise, suddenly say that you are not suitable for their posts, you have to do other jobs transferred are what the sweeping ah, the security of a class, meaning that you are forced to quit. ”

Green Mountain’s reporter saw the signing of a 2005 employment contract. This is a only if there is a “Nantong Green Mountain Integrated Circuit Co., Ltd. Human Resources Department,” a brief seal a contract. The contract, in addition to duration of contract, jobs and other basic terms of remuneration for work, with a greater length of the Party (Nantong Green Mountain) to resolve the employment contract provides for the circumstances to do Sony VGP-BPS9 Battery.

The Green Mountain in-house staff, said in April of this year, the company and employees to re-sign the contract. Contract, the company agreed to pay 220 yuan for each employee’s insurance premiums, but also provides longer working hours, and working hours from 5:30 pm instead of 6:30. “The company said to the premium does not increase the wages, and the last one considered as a whole, received the money and did not increase.”

It is because the “problematic” in the contract, many employees leave the company for vgp bps2c , Sony vgp bps2c compensation when the problem occurred with the differences.

It also led directly to Nantong Green Mountain High staff turnover. An employee had just left, said he joined Green Mountain in the second half of last year, the company staff size was once more than 150 people, but he left, most are familiar with my colleagues have already left, while the number of employees has fallen to less than 100 people. To leave the staff, both general mechanics, are also high-level, including the pioneering work together with the high Xiaoping Zhen, vice president of Island and some of its technical backbone.

Reporter tried on the above statement to the High Xiaoping confirmation, but high refused to respond with the sony battery VGP-BPS2A , VGP-BPS2A.

Chip manufacturing: “low cost” generated by “swallowing gold animals”

Nantong City, Jiangsu Haian County, total investment of 430 million U.S. dollars, China’s first settled in county-level cities for sony vgp bps9 and VGP-AC19V13, 8-inch chip production project, has reached the mark of life and death.

“Because of lack of money, the project progress has been slow.” One industry insider told this reporter that the county government on the progress of the works dissatisfied with MSC has been down the “ultimatum” to make it in mass production before the end of July.

In the meantime, a letter from Nantong Green Mountain unexpected e-mail to employees. June 10, in a letter sent to journalists, who employees said Nantong Green Mountain project internal management turmoil, workers rights for Sony VGP-BPS2A are being infringed great.

Nantong Green Mountain was remarkable, not only because it is settled in county-level cities in China’s first chip projects, but also in its pioneering of “returnees Dr. + Local Government” low-cost mode of operation.

In order to investigate the truth, this reporter again went to MSC.

Green Mountain Status: labor relations strained for VGP-BPS8 , VGP-BPS9

Nantong Green Mountain is located in the MSC county economic development zone. From the factory outside the view, printed with “GMIC” (Green Mountain English abbreviated) sign the standard chip-making plant has already begun to take shape.

Nantong Green Mountain project in 2004, the goal is to build a monthly production capacity of 30000 8-inch 0.25-micron IC production lines. The project by Green Mountain Integrated Circuit Co., Ltd. (registered in British Virgin Islands, is headquartered in Silicon Valley), and MSC to MSC county’s high-tech electronic and Investment Corporation (hereinafter referred to as “Hi-tech electronic”) joint venture. Registered capital of 75 million U.S. dollars, the Green Mountains and High-Tech with our Sony VGP-BPS8 , Sony vgp bps2c battery ect.

Netbooks: In The Strange Place Between Laptops And Smartphones

It seems everywhere you will look companies are hawking their new, tiny, travel-ready netbooks. Wireless companies and cable companies are offering them as incentives in exchange for a service contract and Nokia announced a few weeks ago that they’re working on a version of their own.

They look enticing: Why lug around a regular laptop when a slim,well battery like Dell GK479 sexy thing would keep you connected at the airport or in a far-flung hotel room. But I kept asking myself the same question over and over: If these machines are made almost exclusively for web browsing, why would I use a netbook instead of a smartphone?

I looked at two of these netbooks: Verizon’s HP mini 1000 and AT&T’s Acer Aspire One. For the most part, all these netbooks have about the same specs. Both of these had 2 gig intel atom processor and 1 GB of memory and nice battery HSTNN-LB31.So, the startup process is zippy and roaming the net is a pleasure.I have feeling he’s the market segment netbooks will speak to: People who want little e-mail machines, people who, with the exception of a rare YouTube video, won’t be doing much in the way of multimedia.

Both netbooks had nice, bright screens and both of them featured a smaller than normal keyboard that took some getting used to but was definitely more comfortable than the keyboard of even the roomiest of phones. The HP Mini is definitely better looking, mostly because the Acer One has a protruding battery Acer BTP-42C1 that only a parent could love. But I don’t think a regular user could find very many things that would make one a better choice over the other.

With a built in 3G connection, these netbooks offer amazing portability and the connection is fast enough that you won’t get frustrated watching a video. And that’s one of the huge perks: You can download a flash plug-in and watch internet video to your heart’s delight. It’s also nice that you can install different browsers and use a feature-filled application like Skype.(more imfor:Aspire 3000 battery……;)

Both netbooks had met their match. Their specs were just under the minimum requirements and I found my answer: If something’s going to take up more than pocket space, it better have enough oomph to let you experience the web’s full richness.

Large inventory of Hot ULV Notebook

Before Computex carried out , Intel ULV Platform (Ultra-Low Voltage)laptop batteries are few, but only Acer Aspire T Series and Tsinghua Tongfang S30. Just as we expect, as before, ULV notebook platform at Computex Taipei this year, after the full-blown,a variety of ULV full debut such as Lenovo, the Shenzhou, Hewlett-Packard products , approachable price or even a threat to the traditional low-cost in this market, the time of super – low-power thin notebooks become the focus of discussion.ULV low-power laptops have sprung up everywhere, becoming a new growth point of the notebook market, we have seen, including the domestic, Japanese, Korean department, as well as Europe and the United States and others like Dell GK479 are low-power market in the hair strength. Throughout the second half of the entire notebook industry in the Atom access into this market, when cold, ULV notebook much left undone trend.
Intel ULV platform equipped with a new generation of consumer-level Ultra Low Voltage processor with low power consumption, heat a small and so on. The platform is designed using a notebook computer, with a light and portable, moderate performance, low price, Inspiron E1505 battery and so on. At present, the major brand notebook makers have already introduced the basic product. Here, Xiao Bian first to introduce the mainstream under the current ULV processor, and then I will introduce several are on the market selling ULV notebook platform.
mainstream Intel ULV processor performance analysis of
This is the best of times, Intel’s efforts to strengthen market segments, for manufacturers and consumers a variety of processors, the procurement program, corresponding to the different needs of different price points of products, eliminate waste; the same time, this is the worst of times , we find that in the stores in the illegal use of complex processor business models to Kengpian consumers, in order to achieve the maximization of profits, so I, as a meal, we must be right before buying ULV processor platform, a certain degree of understanding.
Upper right figure we can see that the market is divided into the same mainstream platform processor ULV Celeron, Pentium,Dell GD761, Core 2 Duo, the same as with conventional voltage processor core is also divided into single-core and dual-core, while not exactly the same power consumption, we selected more attention when purchased.
Results from the test run, ULV dual-core processor performance advantages are obvious, even if the product is actually low-frequency single-core speed than a lot of strong high-frequency, so here we give priority to recommend dual-core ULV processor, The following recommended products for everyone that we will also focus on dual-core for the recommendation.
Dell KD476 battery (quotations parameter picture comment) is to the ULV Lenovo’s ultra-low-voltage portable notebook computers with the introduction of a new 14-inch, as a ULV platform for notebook computers, the performance is not its advantages, but it’s life long time and lighter weight to compete in the market an important bargaining chip. The models look all-black tone, leather and metal roof texture texture LOGO perfect fusion of classical reflected in the fashion atmosphere. At present,Toshiba PA3399U-2BRS leather texture, and metal roof LOGO
Lenovo IdeaPad U450A golden ratio using 14-inch 16:9 wide-screen design, is equipped with Intel Core 2 ULV SU7300 dual-core processor (1.3GHz frequency / 3MB 2 Cache / 800MHz FSB), Intel GS45 + ICH9M Chipset , 2GB DDR3 RAM, 250GB hard drive and ATI Mobility Radeon HD4330 dedicated graphics card.
Editorial: Lenovo Lenovo IdeaPad U450A-SSE , Inspiron 1300 battery as the ULV platform series models configured in a higher model, its overall performance was still very good, especially with discrete graphics to make it in the performance of graphics processing certain degree of protection. 6 hours long endurance capabilities and 2kg weight make it the best equipment away from the office.

Why it is useless about the Laptop Battery Claims

It’s one of those things we take for granted: official laptop battery life claims have an extremely tenuous relationship with reality. Not surprisingly, everyone’s using the same tricks to conjure their silly estimates—and they don’t plan on stopping.

AMD, as part of a some kind of PR campaign, is saying the culprit is a battery testing suite called MobileMark 2007:
the parameters for this test include having the screen at just 20 percent brightness, Wi-Fi turned off and no music, video, games or Web pages running. More or less, the test turns a computer into a dimly lit clock, then sees how long it can run like Dell GK479.

That is exactly the kind of test you’d have to run to hit Sony VGP-BPS2C 50-100%-inflated figures, and the perceived ubiquity of the test gives it an air of authority—or at least respectability—within the industry. Using anything more honest would put a manufacturer at a competitive disadvantage.

Whenever I want to learn more about a particular battery chemistry, I refer to this book “Batteries in a Portable World.” You can pickup a print version on Amazon for $4.75. The book is also available for free on-line. It contains a wealth of information,many kinds of batteries such as Dell GD761,Latitude D620 battery…….

Here are a few more tips for getting the longest life from the lithium-based batteries in your laptops and power tools:

• Avoid heat
• Remove the battery when using a power supply for a extended duration
• When not in use, store the battery at a 40 percent charge and keep it in the refrigerator (do not freeze)
• Buy fresh batteries from a retailer who sells a lot of batteries ThinkPad T60 battery and so on. (avoid old batteries)
• A full discharge after every 30 charges will help recalibrate the battery

This is where the story lapses into accusations of subterfuge: AMD says these tests don’t just benefit laptop manufacturers in general—they’re unfairly biased towards Intel, whose chips are optimized for these less-than-realistic scenarios. It’s easy to see how this would be upsetting, but it’s not clear what AMD can really do. They’re proposing a system by which manufacturers show two battery ratings—one the shows a theoretical, low-use maximum, and one that reflects heavy use. (To their credit, Sony already does something like that). Dell inspiron 700m battery admits the practice, but is predictably standoffish about it, while AMD doesn’t inspire much confidence:
By 2010 or 2011, something might show up from a consortium that could be used. It takes two to three years.”
Well, thanks for trying, I guess!

IBM Thinkpad R50 review

The article from laptops-battery.co.uk
IBM released its new ThinkPad R50 series during the fall of 2003. The R Series of notebooks from IBM used to parade as a budget class, that’s no longer the case, the R Series is in fact quite close to the high-end T Series in performance and specs. IBM’s new drive-protection technology senses rough handling and parks the hard drive heads. Should the notebook hit the deck, the drive and its data are likely to remain intact, even if the computer itself is damaged and becomes unusable.

IBM Thinkpad R50
? Centrino 1.4 GHz Processor
? 512 MB DDR333 RAM (CL2.5 according to IBM, no data on memory timings)
? Radeon 7500 Mobility w/32MB Ram
? 5400 rpm 30 GB Hard Drive as Sony VGP-BPS8
? AC Power 
? Rechargeable Thinkpad R50 battery

AthlonXP Powered Desktop Computer
? AthlonXP @ 2.26 GHz Processor
? 1 GB DDR424 RAM (2-2-3-5)
? ABit NF-7 nForce2 mobo
? ATI RAdeon 9700Pro w/128 MB Ram in VGP-BPS9
? 7200 rpm 120 GB WD Hard Drive w/8MB cache

The R50 is based on the Intel Centrino standard, so inside you’ve got a Pentium M processor running at 1.5GHz. The memory complement is a fairly standard 512MB with one SODIM slot left empty for future upgrades, while the 40GB hard disk is smaller than some, but still more than enough for most notebook users. If you do want to free up some hard disk space, IBM has been thoughtful enough to include a DVD/CD-RW combo drive, so you can burn important data off to CD with Dell KD476 Dell U4873.

The R-Series actually has some advantages over its top-of-the-line sibling: The R50 comes with either a 14- or 15-inch display; the T-Series offers just the 14-inch screen. And because the R50 uses the industry-standard 12.7-mm removable-device bay, you can swap in a rewritable DVD drive (for $400 more). All you can get with the T-Series is a CD-RW/DVD ROM because of the 9.5-mm bay that IBM hopes will be a standard eventually in Inspiron 1100 Battery Dell Inspiron 1300 Battery.

The ThinkPad R50 of course features IBM’s easy to distinguish classic black case and with a 13” x 10.4” x 17” (W x D x H) dimension specs we see that it has grown slightly from the previous generation. With a 15-inch XGA screen (14.1″ also available) and weighing a modest 6.6lbs, or 7.1lbs when combined with the AC adapter for travel weight, the ThinkPad R50 can serve as a good desktop replacement or as a reasonably mobile laptop if you’re on the go to Dell Inspiron 1520 Battery. The ThinkPad R50 is a diverse laptop, so let’s dig into the details and see if it’s worth your consideration for purchasing.

Like most ThinkPad notebooks, the R50 is not a music machine, despite its smoothly designed, press-and-hold volume controls. Sound quality is fine, with no distortion or extreme tinniness for Dell IN SPIRON 5100 Battery Dell Inspiron 6000 Battery, but ultimately the audio emitted is too low for more than occasional listening.

The R50 ships with Windows XP Professional pre-installed, while IBM has thoughtfully also included a copy of Norton Anti Virus 2003. I use Norton myself and I find it alarming how many email viruses it spots on a daily basis, so it’s good to see it included with a new machine. ThinkPads also ship with a few special features like the hard disk Active Protection System. This basically stops the hard disk from damaging itself if the notebook is bumped or moved during operation.

Performance is fairly close to the Dell Inspiron 510m that we looked at last week, although the 3D performance is far superior on the R50. Mobile Mark reported a battery life of three hours 42 minutes, which is good, but not spectacular. At least you’ll be able to squeeze half a day’s work out of the Dell Inspiron E1505 Battery Dell Inspiron E1705 Battery.

In conclusion, IMO the thinkpad r50 is a very good laptop select as its price $1,769. If you buy a laptop for General office work and study, the thinkpad t50 is your best choice. It is so thin and light that you can easy to take it to anywhere.

Trackback : PCMG Notebookreview

Today, I made such a topic about that notebook computer users in the use, maintenance, and repairment could sum up some experiences to exchange for better management of their laptop batteries .

1. the regular production of laptop battery manufacturers a variety of parameters clearly marked.
2. buy laptop battery, the best choice nickel-metal hydride batteries or lithium-ion battery.
3. genuine batteries commonly used PC or PVC shell material is very strong, difficult to damage, the general means can not open the laptop battery.
4. neat appearance, there is no extra burr, a certain degree of roughness of the outer surface, and feel comfortable.
5. notebook battery into the battery slot should be around freely, and closely integrated with the machine, while attention to the battery nominal voltage and voltage to correspond to your notebook.
6. to ensure that purchase of the laptop battery charge and discharge of its good performance.
7. under normal circumstances the thinner laptop battery, capacity, the smaller the thicker the laptop battery capacity is also greater.
8. choose the laptop batteries and adapters necessary to ask the dealer asked in detail about the characteristics of batteries and adapters.

If you want to extend notebook battery life, we must also carry out proper maintenance of batteries and maintenance, the following is Ikunori maintenance and maintenance of notes:

1. to avoid laptop battery at a temperature higher than 60 ℃ or lower than -20 ℃ environment, otherwise the use of time and life will be shortened. Laptop battery charging basic method, because laptop battery characteristics vary, so it must be in accordance with manufacturers instructions manual method of charging.
2. if not a long time the machine is best to remove the laptop battery because the case does not boot, will be a gradual loss of laptop battery power
3. due to a general non-rechargeable batteries, lithium batteries, such as the forced charging will cause an explosion.
4. do not laptop batteries and some metal products together to prevent such metal objects touch the battery polarity, short circuit caused by the phenomenon.
5. laptop battery when not in use, if temporarily, you can temporarily release some of them power, but then save it.
6. due to its chemical properties of lithium-ion battery is extremely active in response to intense, so we should not arbitrarily to its demolition. If rain, moisture, dry cloth can be dry, put in dry and ventilated place on their own or with hot air drying of about 40 degrees.
