Polymer lithium-ion battery, a new type of battery with higher energy density, miniaturization, thinning, light weight, high safety, long cycle life and low cost.

The soft-pack polymer lithium battery is safer because it uses a solid electrolyte, which will not leak and explode, but will only expand.

Suitable temperature, anti-cold and heat. The best use of the ambient temperature is about 25 °, because the ambient temperature is too high, the battery will be overcharged and gas is generated, and the ambient temperature is too low, the battery is undercharged.

The fundamental difference is the raw material This is the general source of the various manifestations of the two.

The biggest safety difference between Li-Polymer and Li-Ion batteries is that Li-Ion batteries explode when both cells are heated to a certain degree, while Li-Polymer batteries only have chemistry.

People really don't know much about 18650 batteries, and they have never even heard of the name. They don't even know that these 5 numbers represent a kind of battery, because 18650 batteries are used more in industry, but few in civilian use.
