Novel formulations M.sub.2 UO.sub.2 F.sub.2 and their use in electrochemical cells
 The present invention is directed to compositions of matter having the formula M.sub.2 UO.sub.2 F.sub.2 where each M is any alkali metal ion or mixtures thereof. The present invention is also directed to electrochemical cells having anodes containing anode-active alkali metal, electrolytes capable of conducting ions of said alkali metal, and cathodes containing cathode-active material having the formula M.sub.2 UO.sub.2 F.sub.2 where each M is any alkali metal ion or mixtures thereof. In another embodiment the cathode-active material has the formula UO.sub.2 F.sub.2.
