Title:
MANGANESE COMPOSITE HYDROXIDE AND METHOD FOR PRODUCING SAME, POSITIVE ELECTRODE ACTIVE MATERIAL AND METHOD FOR PRODUCING SAME, AND NONAQUEOUS ELECTROLYTE SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2015/198676
Kind Code:
A1
Abstract:
A precursor of a positive electrode active material for a nonaqueous electrolyte secondary battery which can improve the battery characteristic of the nonaqueous electrolyte secondary battery is obtained. A manganese composite hydroxide is obtained by generating a plate crystal nucleus by setting the pH value of a nucleation aqueous solution containing cobalt and/or manganese to 7.5-11.1 based on a solution temperature of 25°C, and then setting the pH value of a particle growth slurry containing the plate crystal nucleus to 10.5-12.5 based on a solution temperature of 25°C and supplying a mixed aqueous solution that includes a metallic compound containing at least manganese to thereby grow the plate crystal nucleus.
