Applications
Conductive additive for electrodes
Cathode additive for lithium and magnesium batteries; electrode additive for fuel cells, capacitors and flow batteries. Improves electron transport and active area.
Surface treatment of thermal fillers
Coating for alumina, copper, magnesia and other fillers. Enables higher filler loading and better heat transfer between fillers.
Thin-film coating
Sub-1 µm coatings on Al and Cu foils; hydrophilic coating for stainless steel and titanium plates. Prevents oxidation and lowers interfacial resistance.
