Ten characteristics of polymer
Lithium Ion Batteries 1. High working voltage of single battery
The operating voltage of lithium polymer batteries is 3.6v, which is three times the operating voltage of nickel-cadmium batteries and nickel-hydrogen batteries.
2. Higher than 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 is more than other secondary batteries.
5. Light weight
The weight of polymer
Lithium Ion Battery is 40% lighter than steel lithium ion battery of the same capacity and 20% lighter than aluminum lithium ion battery.
6. Self-defining shapes
The manufacturer is not limited to the standard shape, and can make it fit economically. Polymer batteries can add or reduce battery thickness according to customer needs, develop new battery models, are inexpensive, and have a short mold cycle. Some can even be customized according to the shape of the mobile phone to make full use of the battery shell space and increase 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 be less than 35m, which greatly reduces the power consumption of the battery.
8. The guard plate design is 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, so as to save the cost of the battery.
9. Good safety performance.
The structure of the polymer lithium-ion battery is aluminum-plastic soft packaging, which is different from the liquid battery with a metal shell. Once a safety hazard occurs, the liquid battery is easy to explode, while the polymer battery can only be inflated.
10. No pollution to the environment.
Lithium polymer battery does not contain harmful substances, it is a veritable green battery.
