Document Type and Number:
WIPO Patent Application WO/2016/107237
Kind Code:
A1
Abstract:
Provided are a lithium ion battery gradation structure multiple-element material and manufacturing method thereof, and lithium ion battery and anode thereof, the lithium ion battery gradation structure multiple-element material having an average component represented by a formula: LiNixCoyMnzGdO2; 0.4 ≤ x ≤ 0.9, 0 ≤ y + z ≤ 0.6, 0 ≤ d ≤ 0.1, and x + y + z + d = 1, G is one or more elements of Li, Cr, Fe, Mg, Ca, Sr, Ba, B, Al, Y, Sm, Ti, Zn, Zr, V, Nb, Ta, Mo and W; and in the lithium ion battery gradation structure multiple-element material, content of Ni element continuously and progressively reduces from a particle center to a surface. The provided lithium ion battery gradation structure multiple-element material increases lithium ion battery capacity, improves recycle performance and safety performance thereof, and has relative inexpensive costs.
