NONAQUEOUS ELECTROLYTE SECONDARY BATTERY |
| 摘要 |
PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery with high discharging capacity by having a positive electrode using a lithium-containing composite oxide whose unit cell volume is specified as the active material and a negative electrode capable of absorbing/releasing lithium. SOLUTION: A nonaqueous electrolyte secondary battery has a positive electrode using a lithium-containing composite oxide represented by the general formula, Lix Ni1-y Coy O2 , (0<=x<=1.2, 0<y<=0.5), and having a unit cell volume of 100.5-102 cubic angstrom as the active material and a negative electrode capable of absorbing/releasing lithium. The lithium-containing composite oxide is preferable to have a crystallite size ε in the direction of (c) axis calculated from Scherrer equation by using 003 reflection obtained by powder X-ray diffraction of 300-1800Å. |
