| titleOfInvention | Cathode compositions for lithium ion batteries |
| abstract | The invention relates to a cathode composition for a lithium ion battery, which has a core-shell structure and a chemical formula as follows: [ Li ] a (Ni 1‑x‑y‑ z Co x M1 y M3 z )O 2 ] d ·[Li s (Ni 1‑m‑n‑t Co m M2 n M4 t ) 1‑ r M6 r O 2 ] 1‑d The chemical formula of the core is Li a (Ni 1‑x‑y‑ z Co x M1 y M3 z )O 2 The chemical formula of the shell is Li s (Ni 1‑m‑n‑ t Co m M2 n M4 t ) 1‑r M6 r O 2 (ii) a Wherein x, y, z, m, n, t, r, a, s and d are mole fractions, and x>0，0.01≤y≤0.10，0≤z≤0.02，m>N is more than or equal to 0.2 and less than or equal to 0.4, t is more than or equal to 0 and less than or equal to 0.02, r is more than or equal to 0 and less than or equal to 0.02, a is more than or equal to 1.01 and less than or equal to 1.07, s is more than or equal to 1.01 and less than or equal to 1.07, 1-x-y-z is more than or equal to 0.80 and less than or equal to 0.96, 1-m-n-t is more than or equal to 0.30 and less than or equal to 0.70, and d is more than or equal to 0.70 and less than or equal to 1; the powder resistivity of the cathode composition for a lithium ion battery was 120-250 Ω · cm. The cathode composition for the lithium ion battery provided by the invention has a core-shell structure and can be used for preparing the lithium ion battery with better performance. |
