POSITIVE ELECTRODE ACTIVE MATERIAL FOR SECONDARY BATTERIES WITH NONAQUEOUS ELECTROLYTIC SOLUTION, PROCESS FOR THE PRODUCTION OF THE ACTIVE MATERIAL, AND SECONDARY BATTERIES WITH NONAQUEOUS ELECTROLYTIC SOLUTION |
摘要 |
The present invention relates to positive electrode active substance particles for lithium ion batteries, comprising lithium manganate particles comprising Li and Mn as main components and having a cubic spinel structure (Fd-3m), wherein primary particles of the positive electrode active substance have a dodecahedral or higher-polyhedral shape in which none of crystal planes equivalent to the (111) plane are located adjacent to each other, and flat crystal planes are crossed with each other to form a clear ridge, and an average primary particle diameter of the primary particles is not less than 1 µm and not more than 20 µm. The positive electrode active substance particles according to the present invention are excellent in packing property, load characteristics and high-temperature stability. |
