CELLS HAVING CATHODES DERIVED FROM ALKALI SALTS OF CHROMIUM DICHALCOGENIDES

摘要

The present invention is directed to rechargeable current-producing cell comprising: (a) an anode made by an alkali or an earth-alkali metal; (b) a non-aqueous electrolyte solution; (c) a cathode formed by alkali metal salts of chromium dichalcogenides of general formula M'xM''yCrB2, wherein M' and M'' are metals of group I A of the Periodic Table, B is a chalcogen and x and y have values between zero and one.
