| titleOfInvention | Novel lithium ion battery anode material and preparation method thereof |
| abstract | The invention discloses a novel lithium ion battery anode material and a preparation method thereof, wherein the material has the average composition as follows: li 0.6+δ Ni x Co y Mn z O 2 ·E η Delta is more than or equal to 0 and less than or equal to 0.6, x is more than or equal to 0.6 and less than or equal to 1, y is more than or equal to 0 and less than or equal to 0.4, z is more than or equal to 0 and less than or equal to 0.4, η is more than or equal to 0 and less than or equal to 0.1, E is Li 2‑k MO 3‑k/2 K is more than or equal to 0 and less than or equal to 1.8, wherein M is one or more of La, Cr, Mo, Ca, Fe, Hf, Zr, Zn, Ti, Y, Zr, W, Nb, Sm, V, Mg, B and Al, and the content of the dopant E continuously increases from the particle core to the surface and is enriched on the surface layer. The invention can effectively improve the cycle life and the safety of the high-nickel material by controlling the content of each element in the material and the reasonable distribution of the gradient dopant, and has simple material preparation process, continuous controllability and low cost. |
