Porous Copper Foil

Porous copper Foil, fabricated via laser and etching processes, offers customizable pore sizes (10–200 μm) and porosity (≥70 %). While maintaining robust mechanical properties, it significantly reduces current collector weight and enhances cell energy density, making it an ideal lightweight carrier for solid-liquid hybrid batteries, high-energy-density silicon-carbon anodes, and solid-state batteries
