Ten characteristics of polymer lithium batteries

Ten characteristics of polymer lithium battery 1. High single battery working voltage The working voltage of lithium polymer battery is 3.6v, which is three times the working voltage of nickel-cadmium battery and nickel-hydrogen battery. 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 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. Lightweight polymer lithium battery is 40% lighter than steel lithium battery of the same capacity, and 20% lighter than aluminum lithium battery. 6. The shape can be self-meaning. The manufacturer is not limited to the standard shape, and can be made economically suitable. 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 design of the protective plate is simple. Due to the use of polymer materials, the battery will not catch fire or explode, and the battery itself has sufficient safety. Therefore, when designing the protection circuit of the polymer battery, you can consider omitting the PTC and fuse to save the battery. cost. 9. Good safety performance. The structure of the polymer lithium 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. Disclaimer: Some pictures and contents of articles published on this site are from the Internet.
