Battery foil is one of the base materials of lithium batteries for new energy vehicles. Generally, the lithium-ion battery industry uses rolled aluminum foil as the positive electrode collector. Alloys are usually mainly: 1060\1070\1100\1100B. Commonly used thickness: 0.009-0.1mm.
Battery foil is a thin film composed of a series of laminated electrochemical units.
Common materials include aluminum foil, copper foil, stainless steel foil, polymer foil, etc. It can be used as the working medium for the positive and negative electrodes of the battery. It has the functions of conductivity, energy storage, transmission and other functions.
