  • Patent number: 5683835
    Abstract: Lithium manganese ternary oxide Li Mn.sub.2 0.sub.4+x is produced, where 0.ltoreq..times..ltoreq.0.2, by adding carbon to a manganese-containing solution such as manganese acetate and reacting the solution in an inert atmosphere with a lithium-containing compound such as lithium hydroxide and ammonia. Carbon is added in a proportion up to 8 percent of the weight of the Li Mn.sub.2 0.sub.4+x produced, and preferably the proportion of carbon added is in the range 2 to 6 percent by weight of Li Mn.sub.2 0.sub.4+x. The carbon is preferably carbon powder such as carbon black. Preferably, the Li Mn.sub.2 0.sub.4+x produced as a gelatinous precipitate is dried and heat treated. Alternatively, lithium manganese ternary oxide Li Mn.sub.2 0.sub.4+x is produced by reacting a manganese-containing compound with lithium carbonate. The reaction takes place in water and a precipitate is formed which is dried. The dried precipitate may be heat treated. The manganese-containing compound comprises manganese acetate.
