ABSTRACT:
A non-aqueous liquid electrolyte secondary cell employs a vanadium-containing lithium cobalt composite oxide Li.sub.x V.sub.y Co.sub.1-y O.sub.2, where 1.00.ltoreq.x.ltoreq.1.10 and 0.01.ltoreq.y.ltoreq.0.04, is employed as an active material for the positive electrode. Since the vanadium-containing lithium cobalt composite oxide is highly developed in its laminar crystal structure and has a larger grain size, the non-aqueous liquid crystal secondary cell is produced which is high in electrode bulk density and superior in storage characteristics by employing the vanadium-containing lithium cobalt composite oxide as the active material for the positive electrode.
