Aluminum foil is one of the cathode materials for lithium-ion batteries. The coating on its surface can improve the conductivity, chemical stability and mechanical strength of the cathode material, thereby improving the energy density and cycle life of the entire lithium-ion battery.
1235 battery-grade aluminum foil has good conductivity, stability, strong corrosion resistance and is easy to process and form, so it is often used in the preparation of lithium-ion battery electrodes.
The battery cathode foil production methods mainly include hot rolling, remelting aluminum ingot casting and rolling, and electrolytic aluminum liquid direct casting and rolling.
