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.

Due to the high cost of photovoltaic power generation, the industry is subsidized by the countries of the world policy-driven. Governments support the introduction of photovoltaic power generation policy, the world’s photovoltaic industry to overcome the international financial crisis, the beginning of warming, coupled with declining investment costs, so that greatly increased the attractiveness of the investment of solar energy. Over the past 10 years regardless of the global PV industry is the production capacity or are over 40% of the compound growth rate of growth in 2008 global production of photovoltaic cells for 6.4GW, an increase of 60%, and continued high growth over the years situation. China has become the world’s largest producer of photovoltaic cells for laptop battery , the production of photovoltaic cells to occupy the global production of around 40%. One of the world in 2008 before the 25 PV enterprises in China accounted for 8, the total output of 1821MW, China Taiwan accounted for three, the total output for the 723.5MW.

From the point of view of the installed capacity in 2008, the world’s installed photovoltaic cells 5600MW, up 134 percent. China’s installed capacity in 2008 is only 40MW, only 0.7%, one can see, the Chinese market for the installation of photovoltaic cells to be activated, the market has great potential.

Chinese version of the solar roof plan ,the domestic photovoltaic industry to help power the coming of spring. Introduced by the end of March the Ministry of Finance “on accelerating the application of solar PV to implement the views of the construction” and so on, in 2009 as a result of subsidies in principle as standard 20 yuan / Wp, PV power generation means that electricity costs can be reduced to 0.58 yuan / kWh, demand for domestic photovoltaic started. We expect that the subsidy program is only the beginning, is expected to launch in May, “the revitalization of New Energy and Industrial Planning,” is expected to further support the introduction of relevant policies.

Thin-film crystalline silicon photovoltaic cells and photovoltaic cells will be growth, compared the cost advantages of more thin-film laptop battery . Crystalline silicon cells cost-per-watt limit for 1.27 U.S. dollars, while the thin-film battery limits cost-per-watt in the following one U.S. dollars. We measured the current installed capacity of silicon cells cost 19 yuan / wp about the cost of thin film solar cells installed in the 12 yuan / wp around. Both are expected to grow, to increase the share of thin-film batteries. The short term the demand for thin-film batteries to focus on areas with low land cost BIPV, and still is the mainstream crystalline silicon, thin-film batteries will increase the share, as the film base of a small battery, and low cost advantages, in its rapid growth, high growth in crystalline silicon cells.

Warmer in accordance with the demand for solar energy industry, all sectors benefit from the different levels of priority, we recommend high-end thin-film laptop battery manufacturers and component suppliers, followed by crystalline silicon cells or the integration of downstream manufacturers, is once again the upper reaches of polysilicon crystalline silicon cells.
