LITHIUM SECONDARY BATTERY POSITIVE POLE MATERIAL AND METHOD FOR MANUFACTURING IT |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a positive pole active material having good initial discharge characteristics, and high charge/discharge efficiency with a charge/discharge cycle life and heat stability satisfied enough simultaneously. <P>SOLUTION: The positive pole material has a laminar crystal structure, in which the arrangement of oxygen atoms has a cubic structure that constructs an oxide comprising an oxide crystal particles containing lithium element and at least three kinds of transition metal elements, while having a specific surface area of 0.9 to 2.5 m<SP>2</SP>/g, and a tapping density of 1.8 to 2.5 g/cm<SP>3</SP>. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
