Armor Battery Films

The primer improves adhesion, conductivity and corrosion protection between electrode and foil. The company says this gives 5% more energy content and 20% longer life, and allows corrosive salts. Armor Battery Films is part of ARMOR GROUP, a coatings company that makes thermal transfer ribbons and coats more than 2 billion linear meters of thin film a year. It is based in Nantes, France, with a plant in La Chevrolière, and is building a new production site to supply gigafactories.
