Copper foil has the characteristics of symmetrical structure, metal density close to the theoretical density of copper, very low surface profile, high elongation and tensile strength. It has the characteristics of high elongation and tensile strength. At the same time, as the negative collector fluid of lithium battery, double-sided photoelectrolysis copper foil has good thermal and cold expansion resistance, which can obviously extend the battery life. It can be widely used in new energy vehicles, 3C industry represented by smart phones, laptop computers, ESS energy storage system, aerospace and other product batteries.
