Promoting the conversion of S and Li2S using a Co3O4@NC additive in all-solid-state Li–S batteries

Co 3 O 4 @NC as an electronically conductive additive is prepared to promote the conversion of S and Li 2 S in all-solid-state Li–S batteries. And an all-solid-state Li–S battery with the S–Co 3 O 4 @NC–Li 7 P 3 S 11 cathode displays greatly enhanced performance.
