The active material is generally lithium manganese or lithium cobalt, and now there are lithium nickel-cobalt manganese materials, and lithium iron phosphate is used for electric bicycles, and electrolytic aluminum foil with a thickness of 10 - 20 microns is used for the conductive collector.
Positive electrode; the active material is generally lithium manganese or lithium cobalt, and now there is a lithium nickel cobalt manganese material, electric bicycles use lithium iron phosphate, conductive collector using electrolytic aluminum foil with a thickness of 10 - 20 microns.
Diaphragm; a special composite membrane that allows ions to pass through but is an insulator for electrons.
Negative electrode; the active substance is graphite, or carbon with a structure similar to graphite, and the conductive collector is electrolytic copper foil with a thickness of 7-15 microns.
Organic electrolyte; dissolved with lithium hexafluorophosphate carbonate solvent, polymer is used in the gel electrolyte.
Battery shell; divided into steel shell (now square rarely used), aluminum shell, nickel-plated iron shell (cylindrical battery use), aluminum-plastic film (flexible packaging), etc., as well as the battery's cap, but also the battery's positive and negative terminal.
