TITANIUM DISULFIDE-SULFUR COMPOSITES

A titanium disulfide-sulfur (TiS—S) composite particle contains a titanium disulfide (TiS) substrate having solid elemental sulfur (S) disposed directly on a surface of the TiS. The TiSsubstrate has a layered crystalline hexagonal structure of space group P-3 ml and includes at least 100 distinct layers. The TiSand S are present in the composite in a weight ratio (TiS:S) of 20:80 to 50:50. Cathodes and batteries containing the composite particle, as well as related methods, are also disclosed.
