Etched Aluminum Foil

This corrosion aluminum foil, developed for use as a current collector in battery research and energy material applications, provides a specialized surface for improved electrode adhesion. With a thickness of 20 micrometers and a width of 200 millimeters, the foil is engineered for consistent electrochemical performance in experimental setups. The corrosion treatment enhances surface roughness, facilitating better contact between the active material and the current collector, which is critical for evaluating cycling stability and rate capability. Suitable for both academic and industrial R&D environments, this product supports the fabrication of lab-scale cells and prototype devices. The 0.5-kilogram spool offers sufficient material for extended testing series, while the precise dimensional control ensures reproducibility across experiments.
