Carbon Coated Aluminum Foil

Carbon coated aluminum foil can provide excellent static conductive properties and collect microcurrents from active materials, thereby greatly reducing the contact resistance between the positive/negative electrode material and the current collector, and improving the overall performance of the battery. The surface of the carbon coated aluminum foil produced by Yongsheng has no pitting, no bright spot defects, and no wrinkles. The trimming quality does not have cracks, burrs and other defects.

Product Introduction

Carbon coated aluminum foil is a material used for the cathode current collector of lithium-ion batteries after adding a carbon coating layer to the surface of the aluminum foil. Carbon coating refers to coating 0.5g/m2~2g/m2 of carbon on the surface of aluminum foil. After carbon coating treatment, it is beneficial to improve the rate performance of the battery and extend the service life of the battery. Carbon coated aluminum foil can be divided into single-sided carbon coated aluminum foil and double-sided carbon coated aluminum foil. The main alloys commonly used in battery foil are: 1070, 1060, 1235, 1100, 8011, 3003, etc., but the most commonly used ones are 1235, 1060, 1070, 1100 . Aluminum alloys like 3003 are mainly used to produce ultra-high strength battery foils.
