Product Introduction

The Battery Rolled Copper Foil is a cathode material produced by CIVEN METAL specifically for high-end batteries. The uniform thickness and flat shape of the copper foil makes it easy to coat and not to peel off; the uniform grain size of the material can effectively increase the charge/discharge times of the battery and reduce battery failure and improve cycle life; the purity of the copper foil is extremely high and it has excellent electrical conductivity; and the rolled copper foil produced by CIVEN METAL has excellent flexibility and hydrophilic. We can also customize our products to meet different customer requirements.

Calendered copper foil is a product made by repeatedly rolling and annealing high-precision copper strip (thickness is usually less than 150 microns) based on the principle of plastic processing (thickness is usually between 4-100 microns and width is usually less than 800 mm). Its ductility, bending resistance and conductivity are better than electrolytic copper foil, and the copper purity is also higher than electrolytic copper foil

Copper foil is an indispensable raw material for making printed circuit board (PCB), copper clad laminate (CCL) and lithium-ion battery. Flexible circuit board is flexible, which gets rid of the limitations of conventional circuit plane design, and can arrange lines in three-dimensional space. Its circuit is more flexible and has higher technical content. Calendered copper foil has become the best choice for manufacturing flexible printed circuit board because of its flexibility and bending resistance.
