Our battery foil products are divided into power battery foil and lithium battery foil. Among them, the power battery foil is mainly used in the battery pack of new energy vehicles. It is the anode winding aluminum foil material of the battery pack. Compared with the aluminum foil used for lithium battery, it has a high safety factor, and the charging and discharging characteristics of the battery are significantly improved. At the same time, it also has the characteristics of high processing difficulty and high technical requirements. Through the research and development of the production process and technology, the main product characteristics of our power battery foil are higher than the industry level.
