  • Positive electrode active material complex for lithium-ion secondary battery, secondary battery using same, and method for producing positive electrode active material complex for lithium-ion secondary battery
    Patent number: 10868295
    Abstract: There is provided a positive electrode active material composite for a lithium-ion secondary battery, in which, when using as a positive electrode active material of the lithium-ion secondary battery, it can effectively improve high-temperature cycle characteristics. In the positive electrode active material composite for a lithium-ion secondary battery, only on the surface of a lithium transition metal oxide secondary particle (A) composed of one or more of the lithium transition metal oxide particles represented by the following formula (I): LiNiaCobMncM1xO2 . . . (I) or the following formula (II): LiNidCOeAlfM2yO2 . . . (II), a lithium-based polyanion particles (B) is composited with lithium transition metal oxide particles under a specific condition, the lithium-based polyanion particles (B) being represented by the following formula (III) or (III)?: LigMnhFeiM3zPO4 . . . (III) or Mnh?Fei?M3z?PO4 . . . (III)? and being supporting carbon (C) on a surface thereof.
