Overview
Lithium ion copper foil, also known as "double-sided light lithium battery copper foil", is used in lithium batteries as both a carrier of negative electrode active substances a collection transmission of negative electrode electron flow. Therefore, the tensile strength, elongation, density, surface roughness, thickness uniformity, appearance quality of lithium ion battery copper foil have a significant impact on the production process of negative electrodes the electrochemical performance of lithium ion batteries.
