Disclosed are battery cells comprising a sulfur-based positive composite electrode. Preferably, said cells are secondary cells, and more preferably thin film secondary cells. In one aspect, the cells can be in a solid-state or gel-state format wherein either a solid-state or gel-state electrolyte separator is used. In another aspect of the invention, the cells are in a liquid format wherein the negative electrode comprises carbon, carbon inserted with lithium or sodium, or a mixture of carbon with lithium or sodium. The novel battery systems of this invention have a preferred operating temperature range of from -40 DEG C. to 145 DEG C. with demonstrated energies and powers far in excess of state-of-the-art high-temperature battery systems. |
