  • Cathode active material for non-aqueous electrolyte secondary battery and method of manufacturing cathode active material for non-aqueous electrolyte secondary battery
    Patent number: 11735728
    Abstract: A cathode active material for a non-aqueous electrolyte secondary battery including primary particles of a lithium nickel complex oxide represented by a general formula: LizNi1?x?yCoxMyO2+?, and secondary particles in which the primary particles aggregate, wherein a plurality of coated lithium nickel complex oxide particles are formed by disposing a compound containing tungsten and lithium on surfaces of the secondary particles and surfaces of the primary particles positioned inside the secondary particles, and wherein a relative standard deviation of a ratio of a number of atoms of tungsten to a number of atoms of a metallic component other than lithium contained in the coated lithium nickel complex oxide particles is 0.4 or lower.
    Type: Grant
    Filed: November 21, 2018
    Date of Patent: August 22, 2023
    Assignee: SUMITOMO METAL MINING CO., LTD.
    Inventors: Toshiaki Aihara, Hiroyuki Toya
  • Tungsten trioxide
    Patent number: 11390534
    Abstract: A tungsten trioxide whose IWO2.90/IWO3.00 is less than or equal to 0.15 is provided. IWO2.90/IWO3.00 indicates a ratio of a peak intensity IWO2.90 of a (200) plane of WO2.90 to a peak intensity IWO3.00 of a (200) plane of WO3.00 in an XRD pattern.
