LI-NI-BASED COMPOSITE OXIDE PARTICLE POWDER FOR RECHARGEABLE BATTERY WITH NONAQUEOUS ELCTROLYTE, PROCESS FOR PRODUCING THE POWDER, AND RECHARGEABLE BATTERY WITH NONAQUEOUS ELECTROLYTE |
摘要 |
The present invention relates to Li-Ni-based composite oxide particles comprising Mn, and Co and/or Al, wherein Co and Al are uniformly dispersed within the particles, and Mn is present with a gradient of its concentration in a radial direction of the respective particles such that a concentration of Mn on a surface of the respective particles is higher than that at a central portion thereof. The Li-Ni-based composite oxide particles can be produced by allowing an oxide and a hydroxide comprising Mn to mechanically adhere to Li-Ni-based oxide comprising Co and/or Al; and then heat-treating the obtained material at a temperature of not lower than 400°C and not higher than 1,000°C. The Li-Ni-based composite oxide particles of the present invention are improved in thermal stability and alkalinity. |
