The main materials are lithium cobaltate, lithium iron phosphate, etc.;
Negative electrode
The main materials are graphite (C);
Diaphragm
The main material is PE material, which can insulate the positive and negative electrodes and pass through lithium ions, so the lithium-ion battery can be charged and discharged repeatedly (secondary battery);
Electrolyte
The main component is lithium hexafluorophosphate.
