Abstract
Provided are a single crystal multi-element cathode material, a preparation method thereof, and a lithium-ion battery. The multi-element cathode material includes quasi single crystal particles each consisting of a plurality of crystal grains, and element G is present at grain boundaries between the plurality of crystal grains. A concentration of the element G at a g-site of the grain boundaries gradually decreases with an increase in a distance between the g-site and a surface of the quasi single crystal particles. The element G is selected from at least one of Ni, Co, Mn, Ta, Cr, Mo, W, La, Al, Y, Ti, Zr, V, Nb, Ce, Er, and B.
