Why Aluminum Foil for Batteries?

Aluminum foil serves as a critical material in the battery structure, acting primarily as the current collector for the cathode in lithium-ion batteries. Its inherent properties, such as high conductivity, flexibilidade, e resistência à corrosão, make it an ideal choice for facilitating efficient electron flow, enhancing battery life, and improving overall performance.

Advantages of Aluminum Foil in Battery Applications:

  • Alta condutividade: Ensures efficient electron flow within the battery.
  • Leve: Contributes to the overall reduction in battery weight.
  • Resistência à corrosão: Enhances durability and battery life.
  • Flexibility: Allows for versatile battery design and form factors.
