Aluminum Foil For Battery Anode Substrate

Aluminum foil for battery anode substrate is the positive current collector in lithium batteries and the carrier of lithium battery cathode slurry. It plays an important role in lithium batteries. Lithium batteries have high requirements for product safety, so it is also necessary to Strictly grasp the strength and technical level of suppliers. With more than 20 years of production and export experience as a guarantee, Haomei Aluminum offer high quality battery aluminum foil to make every lithium power plant feel at ease and comfortable to use.
