Lithium polymer batteriesare very good. The advantages of this battery are:
1. The working voltage of a single battery can reach 3.6V~3.8V, which is much higher than the 1.2V voltage of nickel-metal hydride and nickel-cadmium batteries.
2. High capacity density. Its capacity density is 1.5 to 2.5 times that of nickel-metal hydride batteries or nickel-cadmium batteries.
3. Small self-discharge. It also loses very little capacity after being left for a long time.
4. Long life expectancy. Its lifespan can reach more than 500 times under normal use conditions.
5. There is no memory effect, there is no need to drain the remaining power before charging, and it is easy to use.
6. Good safety performance. The structure of lithium polymer batteries uses soft aluminum packagingaluminum-plastic, which is different from the metal casing of liquid batteries. Once a safety hazard occurs, liquid batteries explode easily, while polymer batteries only swell.
7. Small thickness. It can be made thinner, ultra-thin, and the battery can be assembled into a credit card.
8. Big capacity. Polymer batteries have 10-15% more capacity than steel-shelled batteries of the same size and 5-10% more capacity than aluminum-shelled batteries.
