Abstract

A battery cathode material includes cathode material, ceramic material, and carbon-containing gel. The cathode material includes lithium nickel cobalt manganese oxide (NCM), lithium nickel cobalt aluminum oxide (NCA), lithium nickel manganese oxide (LNMO), lithium cobalt oxide (LCO), lithium iron phosphate (LFP), lithium nickel cobalt manganese aluminum oxide (NCMA), or combinations thereof. The ceramic material surrounds the cathode material, and includes gallium, aluminum, or tantalum doped lithium lanthanum zirconium oxide (LLZO), lithium zinc titanate (LZTO), lithium aluminum titanium phosphate (LATP), lithium-zirconium phosphate (LZPO), lithium zirconate (LZO), or combinations thereof. The carbon-containing gel wrapping the cathode material, and includes binder and carbon-containing conductive material, in which the binder includes polyvinylpyrrolidone, polyvinyl alcohol, sodium dodecyl sulfonate, sodium dodecylbenzenesulfonate, glucose, carboxymethyl cellulose, alginate, or combinations thereof, and the carbon-containing conductive material includes carbon nanotube.
