Titanium disulfide-sulfur composites

Patent ·
OSTI ID:1925004

A titanium disulfide-sulfur (TiS$$_{2}$$—S) composite particle contains a titanium disulfide (TiS$$_{2}$$) substrate having solid elemental sulfur (S) disposed directly on a surface of the TiS$$_{2}$$. The TiS$$_{2}$$ substrate has a layered crystalline hexagonal structure of space group P-3 ml and includes at least 100 distinct layers. The TiS$$_{2}$$ and S are present in the composite in a weight ratio (TiS$$_{2}$$:S) of 20:80 to 50:50. Cathodes and batteries containing the composite particle, as well as related methods, are also disclosed.
