Double sided carbon coated aluminum foil for Lithium-ion batteries cathode electrode.
Product Type:CAW2.
CAW2 is one of the highest-quality “CA” series product, Due to high conductivity and small size of conventional carbon-coated Al foil ,the obtained functional coating is very thin and highly conductive. The thickness of the functional coating is APPROX.400nm,resulting in improvement of both energy density and power density .we have independent intellectual property for this technology.
