Why lithium batteries use aluminum foil for anode and copper foil for cathode

Lithium-ion battery is a rechargeable battery, in lithium-ion batteries, the selection of foil materials for cathode (negative electrode) and anode (positive electrode) is based on its electrochemical performance and physical characteristics       Copper: excellent electrical conductivity and chemical stability The reason why copper foil is used for the cathode/negative electrode piece is that…
