What are the advantages and disadvantages of polymer lithium batteries?

Advantages and disadvantages of polymer lithium batteries: 1. The working voltage of single battery is as high as 3.6v~3.8v, which is much higher than the 1.2V voltage of Ni-MH and Ni-Cd batteries. 2. Large capacity density, its capacity density is 1.5~2.5 times or higher than that of nickel-hydrogen battery or nickel-cadmium battery. 3. The self-discharge is small, and its capacity loss is also small after being left for a long time. 4. Long life, its cycle life can reach more than 500 times in normal use. 5. There is no memory effect, it is not necessary to empty the remaining power before charging, which is convenient to use. 6. Good safety performance. The polymer lithium battery adopts aluminum-plastic soft packaging in 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 can only blow up. 7. The thickness is small, and it can be made thinner. Disadvantages: 1. The battery cost is high and it is difficult to purify the electrolyte system. 2. To protect the circuit control, overcharge or overdischarge will destroy the reversibility of the battery's internal chemical substances, which will seriously affect the battery's life.
