High surface area ion conductors LiMO2 (where M is a transition metal e.g. Fe, Co or Ni) which may be converted electrochemically to ion conductor LixMO2, where x is less than 1, may be prepared by precipitating a gelatinous form of an oxide of transition metal M from a solution containing ions of the transition metal, converting the gelatinous oxide to NaMO2 e.g. by heating with NaOH, and converting the NaMO2 to LiMO2 by ion exchange (e.g. by heating the NaMO2 in a melt of a soluble Li salt). LiMO2 and LixMO2 may be used as solid electrodes in electrochemical cells. |
