| 摘要 |
The present invention provides a novel lithium nickel composite oxide represented by the composition formula (I) : Li2+xNi1-xO2+y(0.0</=x</=1/7, 0.0</=y<0.3, excluding the case where x=y=0) a preparation process therefor and applications thereof. Where the lithium nickel composite oxide is used as a positive-electrode active material for a nonaqueous secondary battery, high capacity charge-discharge characteristics can be ensured. The novel lithium nickel composite oxide of the present invention is promising as a catalyst, an adsorbent, a dielectric material, and a magnetic material besides such a battery material. <IMAGE> |
