Carbon Coated Aluminum Foil, Cathode Current Collector for Lithium-ion Batteries

Description

Carbon-coated aluminum foil replaces the conventional Al foil as the current collector for the cathode, with improved performance in binding the active materials and the conductivity. In preparation, nanosized conductive graphite and carbon particles are well dispersed and evenly coated on the aluminum foil. The coated carbon layer provides excellent conductivity by reducing the contact resistance between the anode materials and the collection collector. It also reduces the use of electrode binders and improves battery performance.

• Carbon coating layer with a thickness of ~1um
• Compatible with both aqueous and non-aqueous electrode fabrication
• Better electrical conductivity and less internal resistance
• Better mechanical strength and toughness to avoid short circuits caused by dendrite growth
• Improved adhesion between the substrate and the electrode material
• Improve the rate capability of the electrode and enable longer service life of Li-Ion batteries
