Description

Electrolytic copper foil is an essential component of lithium-ion batteries and mainly serves as the negative electrode current collector. It has good conductivity, flexibility, a mature manufacturing process, and a relatively low price. The weight of copper foil accounts for approximately 13% of the total mass of a typical lithium battery, and the cost accounts for about 8%.
