MSE PRO Etched Corrosion Aluminum Foil (20um*200mm*0.5kg) for Battery Research
Introduction
Etched corrosion aluminum foil is a surface-treated current collector produced by chemical or electrochemical etching to create a controlled rough microstructure. The increased surface area enhances adhesion with active materials and improves interfacial conductivity, making it suitable for advanced battery research and energy storage applications.
-
Store the product horizontally at temperatures below 25 °C. Keep away from direct sunlight, moisture, rain, and corrosive gases to prevent aluminum foil discoloration and oxidation.
-
Always wear clean gloves when handling the product to avoid scratching the aluminum foil and contaminating the surface.
