Conductive Nano graphite coated aluminum foil for Lithium-ion super capacitor.
CAW1 is one of the highest-quality “CA” series product, it took five years for the research and development of the product , Nano graphite with excellent performance is produced and used as raw material for the functional coating. Due to high conductivity and small size of the Nano graphite ,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.
