This aluminum foil current collector is developed for use in lithium-ion, sodium-ion, and lithium-sulfur battery electrode fabrication, supporting both positive and negative electrode configurations. The product offers high elongation and tensile strength, ensuring mechanical reliability during coating and assembly processes. Available in single- and double-light surface finishes with thicknesses of 16 μm and 20 μm (200 mm width), the foil provides consistent performance for laboratory-scale and pilot research. A weight tolerance of ±5% is specified, and it is recommended to measure the empty foil mass separately for accurate active material loading calculations. Common applications include serving as a substrate for cathode or anode coatings in power battery cell development and experimental energy storage research.

Lithium-ion batteries, battery cells, power batteries, aluminum foil for backing.

Aluminum foil weight tolerance:+/-5%. When using it, it is recommended that the teacher test the specific quality of the empty foil material at the same time to accurately deduct the weight of the foil material corresponding to the coated research electrode.
