Application current collector of the lithium ion battery
The aluminum foil is used as the current collector of the lithium ion battery. Under normal circumstances, the lithium-ion battery industry use aluminum foil as the positive electrode current collector.
Among battery foils, high-extension, high-resistance and high-surface lithium battery foils not only have strict performance requirements, but also have high requirements on surface quality, size and cutting accuracy.
The battery aluminum foils have 1060, 1070, 1100, 1235 and 3003 aluminum foil. The thickness range is 0.012-0.02mm, and the temper is mostly H18.
1100 aluminum alloy is ordinary industrial pure aluminum with 99.0% aluminum content. It cannot be strengthened by heat treatment. It has low strength, but it has good ductility, formability, weldability and corrosion resistance.
