Information

A lithium-ion battery is a secondary battery (rechargeable battery) that mainly relies on the movement of lithium ions between the positive and negative electrodes to work. During the charging and discharging process, Li+ intercalates and deintercalates back and forth between the two electrodes: during charging, Li+ is deintercalated from the positive electrode, intercalated into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; during discharge, the opposite is true.

Lithium polymer battery, also known as polymer lithium battery, is a chemical battery. Compared with the previous battery, it has the characteristics of high energy, miniaturization and light weight. Lithium polymer batteries have ultra-thin characteristics, and can be made into batteries of different shapes and capacities to meet the needs of some products. The theoretical minimum thickness can reach 0.5mm.
The difference between lithium ion battery and polymer lithium battery:
1. Different raw materials
The raw material of lithium ion battery is electrolyte (liquid or colloid); the raw material of polymer lithium battery is electrolyte, including polymer electrolyte (solid or colloidal) and organic electrolyte.
2. Different security aspects
Lithium-ion batteries are prone to explosion in high-temperature and high-pressure environments; polymer lithium batteries use aluminum-plastic film as the shell, and when the interior uses an organic electrolyte, even if the liquid is very hot, it will not explode.
Three, different shapes
The polymer battery can be thin, any area and any shape, because its electrolyte can be solid or colloidal instead of liquid, and lithium batteries use electrolyte, which requires a solid shell as a secondary package to accommodate the electrolyte.
