Conductive aluminum foil

The 12+1+1μm Primer Aluminum Foil is a composite material formed by coating conductive carbon layers onto electronic-grade aluminum foil substrates, which serves as the cathode current collector for lithium-ion batteries. It cuts contact resistance, strengthens the adhesion of cathode active materials, and shields the aluminum substrate from oxidation and electrolyte corrosion, effectively boosting battery cycle life, safety performance and batch consistency of cells.
