LITHIUM MANGANATE PARTICLES FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERIES AND PROCESS FOR PRODUCING THE SAME, AND NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY |
摘要 |
The present invention relates to lithium manganate particles for non-aqueous electrolyte secondary batteries, having a spinel structure, an average primary particle diameter of 0.4 to 1.8 μm and an average secondary particle diameter (D50) of 8 to 20 μm, a ratio of the average secondary particle diameter (D50) to the average primary particle diameter (D50/average primary particle diameter) being in the range of 10 to 30, and pore diameters of pores in the lithium manganate particles as measured by a mercury intrusion porosimetry method being in the range of 100 to 500 nm, and a process for producing the lithium manganate particles, and a non-aqueous electrolyte secondary battery. The lithium manganate particles according to the present invention are excellent in high-temperature storage characteristics. |
