A titanium disulfide-sulfur (TiS&#x2014;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.

Provided is an apparatus containing, as a cathode catalyst, a metal oxide/carbon catalyst composition. The metal oxide/carbon catalyst composition includes 40 to 95 wt % porous Mn&#x2014;Co spinel oxide nanoparticles of the formula MnCoO. The nanoparticles have an octahedral morphology, an average particle size of 5-100 nm, and average pore sizes of 1-5 nm (where x is the atomic fraction of manganese and 3-x is the atomic fraction of cobalt). The metal oxide nanoparticles are supported on a carbon substrate that contains at least 96 atomic % carbon.
