Description

Primer Carbon Coated Copper/Cu Foil For Lithium-ion Battery Anode Substrate-CCW2.

Carbon-coated Copper/Cu foil is a new type of battery anode substrate. Compared with traditional Copper/Cu foil, carbon-coated Copper/Cu foil has good conductivity, low internal resistance and strong mechanical properties. And good toughness and other advantages, improve the adhesion of electrode materials, increase the discharge capacity of the battery and prolong the service life of the lithium ion battery.

CCW nano carbon modified coating copper foil structure

Graphene-carbon coated Copper/Cu foil CAW series modified current collection products, with independent core patented technology, leading technology, excellent performance, quality assurance, highly recognized by the majority of customers.

After the comprehensive evaluation of the expert committee of Guangdong Battery Industry Association, CCW series products won the gold medal of the 2020 World Battery Industry Expo.

Application: 

Lithium-ion batteries for electric vehicles and energy storage(Si/C).

Lithium-ion batteries for 3C productions (Si/C).

Lithium ion battery in water system.

Si/C anode testing

Advantage: 

Improve the surface tension, and increase the adhesion between the Cu foil and the active material.

Reduce the amount of binder in the electrode, increase the energy density and cycle life of the battery.

Protect the Cu current collector, Prevent corrosion and oxidation of copper foil surface..

Reduce interface resistance and reduce battery internal resistance.

Decrease polarization and improve the rate capability and specific capacity of the electrode material.

Mitigate exothermal reactions and enhance the battery safety.

Improve the production stability and reproducibility, and raise the pass rate of the cell;Increase the consistency and cycling life of the cell, and lower the cost of the production.
