The Disadvantage of Li-Ion Laptop Battery
Among kinds of laptop batteries, the Li-ion battery is the most popular today, it has many advantages such as no memory effect, pollution-free and so on. However, it also has some disadvantages, you must pay attention to them.(toshiba pa3356u-1bas battery)
1.Battery costs more. Mainly in the high price of LiCo02 (Co less resources),electrolyte purification difficult.(toshiba pa3451u-1bas laptop battery)
2.Not high-current discharge. As the organic electrolyte system, and other reasons, the internal resistance of other batteries is relatively large. And called for a smaller discharge current density, the general discharge current at 0.5C bellow, only suitable for use in small electrical currents.
3. Need to protect the line control. A, overcharge protection: battery charge will undermine the positive impact of the structure of the performance and life; also been charged to the electrolyte decomposition, excessive internal pressure caused by leakage and other issues; it must be under constant pressure 4.1V-4.2V charge; B, over-discharged protection: over-discharge recovery will lead to difficulties in active substances, it also needs protection circuit control. Nickel-cadmium batteries (Ni-Cd) Nickel Metal Hydride Battery (Ni-Mh) Wh/Kg is the weight of battery energy density, express per kg battery can provide up to Wh ( watt hour) power.
Based on the above information, we can know Li-ion laptop battery well. The Li-ion laptop batteries may be a little expensive than other kinds of batteries, but i think it is valued. As you do not need to charge and discharge the battery completely, you can charge it when you need. The Li-ion laptop battery is not contaminative to circumstance, this is very important for us to purchase.
