Types Of Lithium-ion Batteries

According to the different electrolyte materials used in lithium-ion batteries, lithium-ion batteries can be divided into
1. Liquid lithium-ion battery (LIB for short)
2. Polymer lithium-ion battery (LIP for short)

Similarities: The positive and negative electrode materials used in liquid lithium-ion batteries and polymer lithium-ion batteries are the same as liquid lithium ions, and the working principles of the batteries are basically the same. Generally, the positive electrode uses LiCoO2, the negative electrode uses various carbon materials such as graphite, and aluminum and copper are used as current collectors.

Difference: The main difference is the difference in electrolytes. Lithium-ion batteries use liquid electrolytes, while polymer lithium-ion batteries use polymer electrolytes instead. This polymer can be "dry" or "colloidal" ", currently most use polymer colloidal electrolytes.
