[1-Minute Battery] Why Aluminum for the Cathode and Copper for the Anode?
Both anodes and cathodes in Li-ion batteries are made by coating a current collector with a slurry of active materials, conductive additives and binders. A current collector is an ultra-thin metallic foil, measured in micrometers ㎛(1×10-6m), which acts as a pathway for electrons to travel and help keep the structure of the coating layer more robust. Typically, Li-ion batteries use aluminum as the current collector for the cathode and copper for the anode. But have you ever wondered why these specific materials are used?
