Abstract | The invention discloses a zinc-tin binary sulfide/carbon nano cubic composite material and a preparation method thereof, the zinc-tin binary sulfide/carbon nano cubic composite material has a cubic microstructure, the particle size is about 200-250nm, and the surface is coated with a carbon material with the thickness of about 5-10nm. The preparation method comprises the following steps: preparing a ZnSn (OH) 6 precipitate from a water-soluble zinc salt, a water-soluble tin salt and polyethylene glycol under an alkaline condition, dispersing the ZnSn (OH) 6 precipitate in a Tris buffer solution to react with dopamine hydrochloride to obtain ZnSn (OH) 6 (at) C, carrying out a high-temperature carbonization reaction in an inert environment, and carrying out a high-temperature vulcanization reaction with sublimed sulfur in the inert environment. The zinc-tin binary sulfide/carbon nanocube composite material has excellent sodium storage performance, can be used as a sodium-ion battery negative electrode material, |
