Mottcell New Energy takes you to understand the structure of lithium battery

(2) Diaphragm —— is a specially formed polymer film with a microporous structure that allows lithium ions to pass through freely, while electrons can not pass through.

(3) The negative electrode —— active substance is graphite, or carbon like graphite structure, and the conductive collector fluid uses an electrolytic copper foil with a thickness of 7-15 microns.

(4) Organic electrolyte —— dissolved the carbonate solvent with lithium hexafluorophosphate, and the polymer uses a gel-like electrolyte.

(5) Battery shell —— is divided into steel shell (square rarely used), aluminum shell, nickel-plated iron shell (cylindrical battery use), aluminum plastic film (soft packaging), etc., and battery cap, is also the positive and negative end of the battery
