Cathodes and electrolytes for rechargeable magnesium batteries and methods of manufacture

Patent ·
OSTI ID:1987188
; ; ;
The invention relates to Chevrel-phase materials and methods of preparing these materials utilizing a precursor approach. The Chevrel-phase materials are useful in assembling electrodes, e.g., cathodes, for use in electrochemical cells, such as rechargeable batteries. The Chevrel-phase materials have a general formula of Mo6Z8 (Z=sulfur) or Mo6Z18-yZ2y (Z1=sulfur; Z2=selenium), and partially cuprated Cu1Mo6S8 as well as partially de-cuprated Cu1-xMgxMo6S8 and the precursors have a general formula of MxMo6Z8 or MxMo6Z18-yZ2y, M=Cu. The cathode containing the Chevrel-phase material in accordance with the invention can be combined with a magnesium-containing anode and an electrolyte.
