    摘要: The material for a lithium battery positive electrode of the present invention is characterized in that a powder of an active material comprising at least one member selected from the group consisting of lithium phosphates, lithium-cobalt phosphates, cobalt oxides and lithium-cobalt oxides, wherein lithium, cobalt and phosphorus are contained in a proportion of more than 0.1 mole of cobalt and more than 0.2 mole of phosphorus both per mole of lithium, is formed into a sheet using a binder comprising an organic polymer, and the present invention affords a material for a lithium battery positive electrode, which is superior in practical use and production efficiency, without impairing the high electromotive force of the novel active material having the aforementioned composition. The production method of the present invention is characterized by extending a binder solution comprising a powder of the above-mentioned active material on a long support sheet, and drying, and affords a long material for a lithium battery positive electrode stably and efficiently by a continuous process.
