3C Battery Coated aluminum foil

13+3+3µm Safety Coated Coating Battery Foil  features a uniformly applied bifunctional composite layer (conisting of conductive carbon-based material and solid-state electrolyte safety primer) on an aluminum current-collecting foil, enhancing protection against penetration by external sharp objects, preventing dendrite penetration, reducing surface resistance of the aluminum foil, minimizing side reactions in the electrolyte solution, and addressing the inherent lack of toughness in metal foils.
