This product is developed as a current collector specifically designed for lithium-ion battery positive electrodes. Made from high-purity aluminum (>99.99%) in a punched mesh configuration, it features a thickness of 0.05 mm, a width of 200 mm, and a pore size of 0.5 × 1.0 mm, which facilitates efficient electrolyte wetting and active material adhesion. With a surface density of 95 ± 15 g/m², this perforated aluminum net offers a balance of mechanical strength and lightweight construction, making it suitable for coin cell or pouch cell assembly in battery research. It is commonly used in experimental setups for electrode preparation and performance evaluation, where consistent current collection and low contact resistance are critical. Standard packaging is 1 kg per roll for convenient laboratory handling.
