This nickel foil product is designed for use as a current collector in experimental energy materials and battery research. Offering a purity of Ni≥99.95%, it provides reliable electrochemical performance with consistent uniformity across thicknesses from 0.002 mm to 0.3 mm and widths up to 150 mm. Typical applications include laboratory-scale electrode fabrication and coin-cell assembly where precise material properties are required. Due to the delicate nature of thin metal foils, careful handling with gloves is recommended, and small-quantity cuts may exhibit minor surface marks. The foil is supplied in pre-cut lengths of 1 meter, with dimensions specified as thickness × width × length, offering flexibility for diverse experimental setups.
