Assembly of Co3S4 nanoporous structure on Ni foam for binder-free high-performance supercapacitor electrode

A facile method was proposed to synthesize a Co 3 S 4 -based binder-free electrode (Co 3 S 4 /Ni foam) in an aqueous solution containing 1-thioglycerol, cobalt nitrate, and sodium thiosulfate at 60 ℃, followed by calcination at 400 ℃. The Co 3 S 4 membrane on Ni foam consists of spherical and ellipt...
