Abstract: Ternary precursor particles used for a lithium-ion battery, the ternary precursor particles having a NixCoyMnz(OH)2, wherein, x+y+z=1, 0<x<1, 0<y<1, 0<z<1; each ternary precursor particle is a spheroidal structure, and comprises a shell, a transition layer and a particle core; the shell is a dense structure, the particle core is a porous structure, the transition layer surrounds the particle core and is sandwiched between the shell and the particle core; each ternary precursor particle is a mixture formed by mixing the nickel hydroxide, the cobalt hydroxide and the manganese hydroxide at the atomic level; a crystallinity of the shell is greater than a crystallinity of the transition layer, and the crystallinity of the transition layer is greater than a crystallinity of the particle core.
Abstract: An anode material used for a lithium-ion battery utilizing a greater part of the storage capacity includes particles in outer dense layer, then inner layer, and then particle core. The outer dense layer is evenly enriched with an M element and an A element, the enrichment decreasing from the outside towards the core. The particle core does include the M element and the A element at a concentration greater than zero and having an average distribution. The M element includes Al, or Al and at least one of Mg, Ti, Zr, Mn. The A element includes F, or F and at least one of B, P, and N. A method for manufacturing the anode material and a lithium-ion battery are also disclosed.
