Ten hotspots of polymer lithium batteries
1. High working voltage of single battery
The working voltage of polymer battery is 3.6v, which is 3 times that of nickel-cadmium battery and nickel-hydrogen battery
2. Higher specific energy.
The current specific energy of polymer batteries is 140wh/kg, which is 3 times that of nickel-cadmium batteries and 1.5 times that of nickel-hydrogen batteries.
3. The self-discharge is small, and the storage capacity loss is small after a long time.
4. Long cycle life.
At present, the cycle life of polymer lithium-ion batteries has reached more than 1,000 times, and can reach tens of thousands of times at low depths of discharge, which surpasses other secondary batteries.
5. Severity
The weight of polymer lithium-ion batteries is 40% lighter than steel lithium-ion batteries of the same capacity and 20% lighter than aluminum-ion batteries.
6. The shape of self-meaning
Manufacturers are not limited to standard shapes, which can make them suitable for economy. Polymer batteries can increase or decrease battery thickness according to customer needs, open new battery models, are inexpensive, and have short mold cycles. Some can even be customized according to the shape of the mobile phone to make full use of The battery shell space increases the battery capacity.
7. Small internal resistance
The internal resistance of polymer batteries is smaller than that of liquid batteries. At present, the internal resistance of domestic polymer batteries can even reach 35m, which greatly reduces the power consumption of the battery.
8. The design of the protective plate is very simple.
Due to the use of polymer materials, the battery does not catch fire or explode, and the battery itself has sufficient safety. Therefore, the ptc and fuse can be omitted when designing the protection circuit of the polymer battery, which saves the cost of the battery.
9. Good safety performance.
The structure of the polymer lithium-ion battery is an aluminum-plastic soft pack, which is different from the liquid battery with a metal shell. In case of a safety hazard, the liquid battery is easy to explode, while the polymer battery can only inflate the drum.
10. No pollution to the environment
The polymer battery contains no harmful substances and is a veritable green battery.
