Title:
リチウム二次電池正極用の材料並びにその製造方法
Document Type and Number:
Japanese Patent JP4444121
Kind Code:
B2
Abstract:
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.
