NICKEL COMPOUND HYDROXIDE AND METHOD FOR PRODUCING SAME, POSITIVE POLE ACTIVE SUBSTANCE FOR NONAQUEOUS ELECTROLYTE SECONDARY CELL AND METHOD FOR PRODUCING SAME, AND NONAQUEOUS ELECTROLYTE SECONDARY CELL |
摘要 |
Provided is a lithium composite oxide having a uniform and suitable particle size and high specific surface area due to a hollow structure that can be produced on an industrial scale. A nickel composite hydroxide as a raw material thereof is obtained controlling the particle size distribution of the nickel composite hydroxide, the nickel composite hydroxide having a structure comprising a center section that comprises minute primary particles, and an outer-shell section that exists on the outside of the center section and comprises plate shaped primary particles that are larger than the primary particles of the center section, by a nucleation process and a particle growth process that are separated by controlling the pH during crystallization, and by controlling the reaction atmosphere in each process and the manganese content in a metal compound that is supplied in each process. |
