  • Lithium nickel cobalt manganese oxide positive active material having concentration gradient of nickel, cobalt, and manganese and precursor thereof and preparation methods
    Patent number: 9847525
    Abstract: A precursor of a modified ternary material for a lithium ion battery positive material belongs to the technical field of application of lithium ion battery positive materials. A molecular formula of the precursor is: (Ni1/3Co1/3Mn1/3)(OH)2, and the precursor consists of three layers. An inner layer of the precursor is a ternary material with the Co content of more than ? and equal Ni and Mn content, and the molecular formula of the inner layer of the precursor is: (Ni1/3?xCol/3+2xMn1/3?x(OH)2, where 0<x<?. An outer layer of the precursor is a ternary material with the Co content of greater than 0 to ? and equal Ni and Mn content, and the molecular formula of the outer layer of the precursor is: (Ni0.5?yCo2yMn0.5?y)(OH)2, where 0<y<?. An intermediate layer of the precursor is a concentration gradient composite material of the two materials of the inner layer and the outer layer of the precursor.
