    Microporous Copper Aluminum Foil Solid State Battery Lithium Battery

    Microporous Copper Foil Aluminum Foil Solid-state Battery Lithium Battery For New Energy Power Battery-grade Current Collector Porous Punching

    1. Product Overview​

    Our precision-engineered ​​micro-perforated copper/aluminum foils​​ are designed for next-generation solid-state and lithium-ion batteries. With customizable porosity (up to 40%) and zero burrs, these foils enhance electrolyte infiltration and electrode kinetics while maintaining structural integrity.

    ​Key Applications:​

    • Solid-state batteries
    • High-energy-density lithium batteries
    • Power batteries for EVs/ESS

    2. Customizable Specifications​
