  • Process for synthesizing lixmny04 intercalation compounds
    Patent number: 5747193
    Abstract: A novel process for making Li.sub.x Mn.sub.y O.sub.4 intercalation compounds, wherein 0<x.ltoreq.2 and 1.7.ltoreq.y.ltoreq.2, comprises the steps of: (1) synthesizing a lithiated manganese oxide precursor by reacting lithium hydroxide, manganese dioxide, and one or more polyhydric alcohols; and (2) heat-treating the lithiated manganese oxide precursor. The intercalation compounds are effectively employed as active components of positive electrodes in rechargeable lithiated intercalation battery cells.
