Manganese composite hydroxide particles, positive electrode active material for non-aqueous electrolyte secondary battery, non-aqueous electrolyte secondary battery, and production methods thereof |
| abstract |
PROBLEM TO BE SOLVED: To provide a lithium manganese composite oxide particle having a small particle size and a uniform particle diameter and having a hollow structure, and a method for producing such lithium manganese composite oxide particle. SOLUTION: A nucleation aqueous solution containing a metal compound containing manganese and an ammonium ion supplier is controlled by a crystallization reaction so that the pH value becomes 12.0 to 14.0 based on a liquid temperature of 25 ° C. A nucleation step in which nucleation is performed in an air atmosphere, and an aqueous solution for particle growth containing the nuclei formed in the nucleation step in a pH value range of 10.5 to 12.0 based on a liquid temperature of 25 ° C. The manganese composite hydroxide particles obtained in the particle growth step in which the nuclei are grown by controlling the atmosphere to be lower than the nucleation step and switching the atmosphere to an inert atmosphere within 30% of the total time from the start of the particle growth step And a lithium compound are mixed and fired.
