Carbon Coated Copper Foil For Li-Ion Battery Anode Current Collector
Conductive carbon coated copper foil can replace conventional Al foil as better anode substrate with improved properties.
----Better electrical conductivity and less internal resistivity
----Better mechanical strength and toughness to avoid short circuit caused by dendrite growth
----Better coating strength with electrode material
----Therefore, it will provide larger discharging capability and longer service life for Li-Ion batteries
