Battery Shell Foil

Battery aluminum foil is one of the base materials for new energy vehicle lithium batteries. Generally, the lithium-ion battery industry uses rolled aluminum foil as the positive electrode collector. The main constituent materials of lithium-ion batteries include electrolyte, separator materials, positive and negative electrode materials, etc. The positive electrode includes a current collector composed of aluminum foil and lithium cobaltate or lithium iron phosphate. At present, general battery foil products generally require a strength of ≧180Mpa, and it is pure aluminum alloy, which means that battery foil is a product that has extremely strict requirements on the base material of aluminum foil, and battery foil requires the thinnest thickness and highest strength, the highest surface dyne value, the smallest thickness difference, the best plate shape, and the cleanest surface.
