                The features of  Changyuan aluminum foil for Lithium ion battery cathode material

                1. Excels in foil flexibility

                Due to its flexibility, this foil is resistant to the expansion and contraction of battery at the time of charge/discharge.

                2.Good in smoothness on either side

                The active material to provide the functionality of battery can be applied uniformly.

                3.Small in foil thickness variation

                Due to its small thickness variation, the coating thickness variation of active material can be suppressed.

                To raise the output power, the HEV battery has a thinner active material layer than the commercial batteries.

                The smaller the foil thickness variation, the smaller can be made the thickness variation of the active material.

                This advantageous property of our product has been highly appreciated by every automotive battery manufacturers, and is often a decisive factor in accepting orders.

                Why choose aluminum foil as cathode substrate for lithium battery?

                Conductive carbon coated Aluminium foil can replace conventional Al foil as battery cathode substrate with improved properties

                 Better electrical conductivity and less internal resistivity

                Better mechanical strength and toughness to avoid short circuit caused by dendrite growth

                Improved adhesion to the electrode material

                Provides larger discharging capability and longer service life for Li-Ion batteries
