High Tensile Copper Foil for Battery Current Collector

This high tensile copper foil is an ultra-thin electrolytic copper foil designed for lithium battery anode current collectors. It has a thickness of 6??m, which is thinner than traditional copper foils, reducing battery weight and improving energy density. The foil has high tensile strength, withstanding the tension during battery winding processes without breaking, ensuring production stability. It has excellent electrical conductivity with low resistivity, ensuring efficient current collection and transmission. The surface is smooth and clean with no defects, ensuring good bonding with anode materials. The product has uniform thickness and consistent performance, meeting the requirements of large-scale lithium battery production.
