Methods are provided for forming an electrode. The method can comprise thermally reducing GeOpowders at a reducing temperature of 300&#xb0; C. to 600&#xb0; C. to produce Ge particles; mixing the Ge particles with an organic binder and a carbon source; and pressing the Ge particles with the binder and the carbon source to form the electrode. Electrodes are also provided that include a plurality of microparticles comprising Ge grains, an organic binder, and a carbon source, wherein the Ge grains comprise cubic Ge and are bonded together to form Ge particles, and wherein the Ge grains define nanopores within the electrode.

Lithium ion battery electrode

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.
