Electrodeposition and rolled battery-grade copper foil (6–25 µm), aluminum foil (12–25 µm), and 1 µm conductive-carbon-coated Al/Cu current collectors for Li-ion, Na-ion, and supercapacitor doctor-blade coating.
Current-collector surface energy and contact resistance directly govern electrode slurry adhesion, high-rate C-rate capability, and cycle life. We supply anti-tarnish treated electrolytic copper anode foil (8–12 µm), battery-grade aluminum cathode foil (15–20 µm), and 1 µm nano-carbon-coated aluminum (C-Al) and copper (C-Cu) foils.
Conductive carbon primer layers reduce interfacial contact resistance by 40%–70%, prevent binder delamination in aqueous and high-loading LFP/NMC/Si electrodes, and suppress aluminum pitting corrosion.
