Transition metal oxide was considered as an effective cathode additive to depress ‘shuttle effect’ in lithium-sulfur (Li-S) batteries via forming a strong polar chemical bond with polysulfides. Here, we firstly synthesized unique S@Ni/NiO/ZnSnO3 microcubes as composite cathodes for Li-S batteries, in which Ni/NiO films were deposited onto surface of as-prepared ZnSnO3 microcubes via a hydrothermal reaction and later calcinations process. The S@Ni/NiO/ZnSnO3 composite showed attractive electrochemical performances with a high initial discharge-specific capacity of 1070...
