ABSTRACT:
The solubility and reactivity of CrO.sub.3 with the commonly used non-aqueous organic electrolytes used for high voltage electrochemical cells is overcome by forming an intercalation compound of CrO.sub.3 with graphite. The cathodes of such intercalation compounds, methods of making same and cells containing such electrodes are described. In addition it has been found that cells containing such CrO.sub.3 cathodes are readily rechargable and thus provide an excellent secondary battery.
