The cathode layers lack costly and environmentally unfriendly nickel and cobalt. The cathode layers are composites that include agglomerates of sulfurized-carbon particles in a conductive binder and interconnected by sp2-bonded carbon materials, such as carbon nanotubes or nanoribbons, that extend within the agglomerates and between the sulfurized-carbon particles.19engUtility patentUS11605817B2
