  • Publication number: 20200052295
    Abstract: A positive electrode active material reduces an eluted lithium amount when used for a nonaqueous electrolyte secondary battery, and a nickel-manganese composite hydroxide as a precursor. A nickel-manganese composite hydroxide contains a secondary particle formed of a plurality of mutually flocculated primary particles and is represented by Formula (1): Nix1Mny1Mz1(OH)2+? (0.70?x1?0.95, 0.05?y1?0.30, x1+y1+z1=1.0, and 0???0.4 are satisfied; and M is at least one element selected from Co, Al, Ti, V, Cr, Zr, Nb, Mo, Hf, Ta, Fe, and W). The nickel-manganese composite hydroxide has a manganese-rich layer from a particle surface to a particle inner part of the secondary particle. The manganese-rich layer is represented by Formula (2): Nix2Mny2Mz2(OH)2+?. The thickness of the manganese-rich layer is at least 5% and up to 20% of the radius of the secondary particle.

  • Patent number: 10553870
    Abstract: The present invention industrially provides: a non-aqueous electrolyte secondary battery having a high energy density and high cycling characteristics; a cathode active material for a non-aqueous electrolyte secondary battery having a high packing efficiency; and a nickel manganese containing composite hydroxide having a small particle size, a narrow particle size distribution, and a high sphericity. When producing the nickel manganese containing composite hydroxide by a crystallization reaction using material solution where metal compounds including nickel and manganese dissolve, a nucleation process is performed in a non-oxidizing atmosphere by stirring an aqueous solution for nucleation, that includes the quantity of the material solution corresponding to 0.6% to 5.0% of the whole amount of substance of metal element included in a metal compound used for the overall crystallization reaction.
