Product features:

Significantly improving the adhesion between copper foil and negative electrode materials (existing graphite and other materials generally have low adhesion), especially for the new silicon carbon negative electrode, a carbon coating layer needs to be added (this carbon layer has a much higher internal resistance than copper foil and capacity loss). This water-based coating has weak water resistance, which can lead to the risk of detachment on both bonding surfaces... Our roughened copper foil can significantly increase the specific surface contact area without the cost of carbon coating, as well as the hidden dangers and side effects (if there are special requirements, the combination of the two can improve the bonding strength of the two contact layers, thereby essentially improving water resistance).

Product Introduction:

Our self-developed roller coating equipment and process can perform ultra-thin safety coating treatment on frosted foil, which can effectively control oxidation and corrosion. It not only stabilizes the resistance, but also maintains the mechanical resistance and stability of the current collector in the event of sudden temperature rise, playing a role in corrosion prevention, flame retardancy, and preventing thermal runaway.
