OEM Supply Cuni Foil - ED Copper Foils for Li-ion Battery (Double-matte) – CIVEN Detail:

Product Introduction

Electrodeposited Copper foil for single (double) sided gross lithium battery is a professional material produced by CIVEN METAL to improve the performance of battery negative electrode coating. The copper foil has a high purity, and after roughening process, it is easier to fit with the negative electrode material and less likely to fall off. CIVEN METAL can also custom slit the material to meet the requirements of different customers’ products.

Specifications

CIVEN METAL can provide single (double) sided gross lithium copper foil of different widths from 8 to 12µm in nominal thickness.

Performance

The product is formed with a columnar grain structure, the roughness of the glossy surface of the double-sided hairy lithium copper foil is rougher than that of the double-sided light lithium copper foil, and its elongation and tensile strength are lower than that of the double-sided light lithium copper foil, among other properties (see Table 1).

Applications

It can be used as anode carrier and collector for lithium-ion batteries.

Advantages

Single (double) side lithium copper foil light (hair) surface is rougher than double-sided light lithium copper foil, its bond with the negative electrode material is more solid, not easy to fall out of the material, and the match with the negative electrode material is strong.
