Aluminum Foil for Lithium-ion Batteries
Aluminum foil for lithium-ion batteries refers to the aluminum and aluminum alloy foil used as the positive electrode current collector of lithium-ion batteries. Together with cathode materials such as lithium iron phosphate, lithium cobalt oxide and lithium manganese oxide, it forms part of the battery’s positive electrode. Depending on the manufacturing process and material, it can be classified as plain foil, coated foil or composite aluminum foil.
Aluminum foil for lithium-ion batteries is a high-end product. Because reducing current collector thickness increases battery energy density, Chinese battery manufacturers are pressing for ever thinner lithium-ion battery foil.
With the rapid growth of the lithium-ion battery industry, composite foil and coated foil with better performance will become the main materials for lithium-ion battery current collectors in the future.
