The present invention discloses a ternary material and a preparation method thereof, a battery slurry, a positive electrode and a lithium battery. The ternary material has a composition represented by the general formula LiNi 1-x-y Co x M y O 2 , where the M is Mn or Al, 0<x<1, 0<y<1, x+y<1; and particles of the ternary material include three-level particles having a particle diameter ranging from small to large, the three-level particles include primary particles having a crystal structure, intermediate particles formed by partial melting of a plurality of primary particles, and secondary spheres formed by agglomeration of the intermediate particles. |
