Key Bnenefit of 13+3+3µm Safety Coated Coating Battery Foil 

1. The composite coating design combining a carbon layer and a solid-state electrolyte layer endows the aluminum foil with both flexible support and mechanical stiffness, effectively preventing dendrite penetration, enhancing protection against puncture by sharp external objects, and inhibiting crack propagation within the metal foil.

2. The conductive carbon coating reduces the surface resistance of the aluminum foil, improving the cell's high-rate discharge performance and power density.

3. The solid-state electrolyte layer enhances ion transport efficiency while minimizing electrochemical side reactions between the electrolyte and the cathode material.
