Abstract
A cell operable at temperatures between 100.degree. C. and 200.degree. C. includes a non-aqueous electrolyte which comprises at least one solvent belonging to the class of aromatic or aliphatic linear sulfones. The negative active material of the cell may be lithium, for example, and its positive active material is selected from the group constituted by oxides, oxisalts, and sulfides. The electrolyte includes as a solvent, in particular, dimethylsulfone alone or mixed with other aromatic or aliphatic linear sulfones.
Claims3
An electrochemical cell having a negative active material, a positive active material, and a non-aqueous electrolyte, the cell being capable of operation in a temperature range between 100.degree. C. and 200.degree. C., wherein the negative active material is selected from the group consisting of alkali metals, alkaline earths, magnesium, and aluminum, the positive active material is selected from the group consisting of CuO, Cu.sub.4 O(PO.sub.4).sub.2, CF.sub.x, MnO.sub.2, V.sub.2 O.sub.5, MoS.sub.3, TiS.sub.2, V.sub.2 S.sub.5, V.sub.6 O.sub.13, MoS.sub.2, and NiPS.sub.3, and wherein said nonaqueous electrolyte consists of at least one solvent selected from the group consisting of dimethylsulfone alone and mixtures of dimethylsulfone with other aromatic or aliphatic linear sulfones.
