[0002] Battery aluminum foil is one of the indispensable key materials in lithium-ion batteries and other types of batteries. It is mainly used for positive electrode current collectors. It not only serves as a carrier for current transmission, but also serves as a supporting structure for active substances, ensuring that electrochemical reactions can proceed efficiently. Battery aluminum foil is made by refining aluminum raw materials into aluminum plates, which are then rolled into aluminum foil. Battery foil is made by casting and rolling aluminum liquid, and titanium wire is used to assist in dissolution during the processing of aluminum liquid.
