ABSTRACT:
Novel fire-retardant electrolyte compositions are provided. These compositions comprise a lithium salt dissolved in a fire-retardant solvent selected from the group consisting of phosphates, phospholanes, cyclophosphazenes, silanes, fluorinated carbonates, fluorinated polyethers and mixtures thereof. The electrolyte composition optionally contains a CO.sub.2 -generating compound. Also provided are fire-retardant batteries and fire-retardant conductive films formulated with such compositions, as well as methods of manufacturing such films.
