Battery Current Collectors – Lithium Battery Copper Foil

Copper foil serves as the negative electrode (anode) current collector in lithium-ion batteries, directly impacting energy density, battery life, and safety. HSMetal supplies ultra-thin electrolytic copper foil with mass production capabilities from 4.5μm to 12μm, with advanced technology enabling 3.5μm ultra-thin foil production. Industry data shows that transitioning from 8μm to 6μm copper foil can improve cell energy density by 3–5%, while the shift from 6μm to 4.5μm can boost it by 5–10%. Each 1μm reduction in thickness increases energy density by approximately 1–2%. Our 3.5μm foil, roughly 1/22 the diameter of a human hair, represents the cutting edge of battery material technology.

Available thicknesses: 4.5μm, 5μm, 6μm, 7μm, 8μm, 9μm, 10μm, 12μm
