Components Of Lithium-ion Batteries

Positive electrode: Active substances are usually lithium manganese or cobalt oxide, nickel cobalt manganese acid lithium materials, electric bicycles are commonly used nickel cobalt manganese acid lithium (commonly known as ternary) or ternary + a small amount of manganese acid lithium, pure manganese acid lithium and lithium iron phosphate is due to large size, poor performance or high cost and gradually fade out. Conductive electrode fluid uses electrolytic aluminum foil with thickness 10--20 micron.

Diaphragm: A specially formed polymer film, which has a microporous structure, allows lithium ions to pass freely, and electrons cannot pass.

Negative: The active matter is graphite, or graphite structure of carbon, conductive set of fluid using 7-15 micron thickness of electrolytic copper foil.

Organic electrolyte: A carbonate solvent with six phosphoric acid, and a gel electrolyte for the polymer.

Battery Shell: Divided into steel shell (square type rarely used), aluminum shell, nickel-plated iron shell (cylindrical battery use), Aluminum plastic film (flexible packaging), as well as battery caps, is also a battery of positive and negative tip.
