Introduction to the advantages of polymer lithium batteries

Advantages of polymer lithium battery 1. The working voltage of the single battery is high. The working voltage of the single battery is as high as 3.6v~3.8v, which is much higher than the 1.2V voltage of nickel-metal hydride and nickel-cadmium batteries. 2. The capacity density is large, the capacity density is 1.5~2.5 times of Ni-MH battery or Ni-Cd battery, or higher. 3. The self-discharge is small, and the capacity loss is very small after being placed for a long time. 4. The life is long. The cycle life can reach more than 500 times. 5. There is no memory effect. It is not necessary to empty the remaining power before charging, and it is convenient to use. 6. The safety performance is good. The polymer lithium battery adopts aluminum-plastic soft packaging in the structure, which is different from the metal shell of the liquid battery. Once a safety hazard occurs, the liquid battery is easy to explode, and the polymer battery will only blow up at best. 7. Ultra-thin, the battery can be assembled into a credit card. 8. Light weight: the battery using polymer electrolyte does not require a metal shell as a protective outer packaging. The weight of the polymer battery is 40% lighter than the steel shell lithium battery of the same capacity and specification, and compared with the aluminum shell The battery is 20% lighter. 9. Large capacity: the polymer battery has a capacity of 10-15% higher than that of the steel shell battery of the same size and 5-10% higher than that of the aluminum shell battery. 10. Small internal resistance: the internal resistance of the polymer battery cell is lower Generally, liquid batteries are small. 11. Good discharge characteristics. Polymer batteries use gel electrolytes. Compared with liquid electrolytes, gel electrolytes have stable discharge characteristics and a higher discharge platform. 12. The design of the protection board is simple. Because the polymer material is used, the battery core does not catch fire or explode, and the battery itself has sufficient safety. Therefore, the protection circuit design of the polymer battery can be considered to omit the PTC and fuse, thereby saving battery costs.
