MATERIAL FOR POSITIVE ELECTRODE OF LITHIUM SECONDARY BATTERY AND PROCESS FOR PRODUCING THE SAME

Stable supply of a cathode material for a lithium secondary battery that excels in sinterbility and composition stability and can exhibit satisfactory battery performance is accomplished by reducing to 100 ppm or less both the contents of Na and S being impurity elements in multiple oxides as materials for a cathode material for a lithium secondary battery and carbonic salts as precursor materials for the production of a cathode material for a lithium secondary battery.
