Collection: Current Collectors & Electrode Substrates

Battery Current Collectors and Electrode Substrates

Find current collectors and conductive electrode substrates for battery fabrication, electrochemical testing, fuel-cell research and supercapacitor experiments. The range includes copper and aluminum foil, carbon-coated foil, nickel foam, metal mesh, titanium and tin foil, stainless steel foil, carbon paper and carbon cloth.

Selection should be based on electrode polarity, chemical compatibility, conductivity, corrosion resistance, thickness, porosity, surface treatment and the dimensions required by your coating or cell format. Copper is commonly evaluated for anode current collection and aluminum for cathode current collection in lithium-ion research, while nickel foam, mesh and carbon substrates support other chemistries and electrochemical configurations. Compare the exact material grade and dimensions on each product page. For prepared formats, visit battery electrode sheets; for coating and cutting, see cell-making equipment and tools.
