Aluminium Foils for Battery

While aluminum foil is the go-to material for lithium-ion batteries, other types of aluminum foils are used in different battery technologies:

• Copper Foil:
  Copper foil is as the current collector for the anode in lithium-ion batteries, while aluminum foil is for the cathode. Copper’s excellent conductivity makes it ideal for this application.
• Nickel Foil:
  Nickel foil is another alternative applciations in some batteries. Especially in nickel-based batteries. It offers good conductivity and corrosion resistance, but it’s more expensive than aluminum.
• Carbon-Coated Aluminium Foil:
  In some advanced battery designs, aluminum foil is coated with a thin layer of carbon to improve its performance. The carbon coating enhances conductivity and helps extend the battery’s lifespan.
