Lithium Battery Materials Conductive Carbon Coated Copper Foil
Lithium Battery Materials Conductive Carbon Coated Copper Foil
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
