Li-Ni COMPOSITE OXIDE PARTICLES AND NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY |
| 摘要 |
The present invention relates to Li—Ni composite oxide particles having a composition of Lix(NiyCo2(1-y)/5Mn3(1-y)/5)1-zMzO2 wherein x, y and z represent 1.00≦x≦1.10; 0.65<y<0.82; and 0≦z<0.05, respectively; and M is at least one element selected from the group consisting of Al, Zr and Mg. The Li—Ni composite oxide particles of the present invention exhibit a high initial discharge capacity and are excellent in first-cycle charge/discharge efficiency when used as a positive electrode active substance for non-aqueous electrolyte secondary batteries. |
