| titleOfInvention | A lithium-ion battery |
| abstract | In order to overcome the problem of the decrease of cycle performance caused by the dissolution of manganese ions and the decomposition of the electrolyte in the existing lithium nickel manganate battery, the present invention provides a lithium ion battery, including a positive electrode, a negative electrode and a non-aqueous electrolyte, and the positive electrode includes a positive electrode A material layer, the positive electrode material layer includes a lithium nickel manganate material shown in formula I and a compound shown in formula II; LiNi x Mn 2-x O 4 formula I, wherein 0<x<2; The non-aqueous electrolyte includes a non-aqueous organic solvent, an electrolyte salt and a first additive, and the first additive includes a boron-containing lithium salt; the lithium ion battery satisfies the following conditions: 0.1≤(a+b)*m≤5 ; and 0.005≤a≤1, 0.01≤b≤3, 1≤m≤3. The lithium ion battery provided by the invention can maintain the high-voltage lithium nickel manganate structure stability and oxidation resistance under the condition of high energy density, and significantly inhibit the decomposition reaction of the electrolyte, thereby improving the cycle performance of the battery. |
