| titleOfInvention | Gradient fluorine-doped ternary cathode material with low lattice stress and preparation method thereof |
| abstract | A gradient fluorine-doped ternary cathode material with low lattice stress and a preparation method thereof. The invention belongs to the field of lithium ion batteries, and particularly relates to a gradient fluorine-doped ternary cathode material with low lattice stress and a preparation method thereof. The invention aims to solve the problems that the lattice stress is generated due to the change of the proportion of transition metal elements in the oxide anode material of the lithium ion battery at present, so that the lattice stress of the oxide anode material of the lithium ion battery is higher, and the cycle stability and the rate capability of the electrode material are influenced. The method comprises the following steps: firstly, preparing a mixed metal salt water solution; secondly, preparing a precipitator aqueous solution; thirdly, preparing a complexing agent for dissolving in water; fourthly, preparing a fluoride aqueous solution; fifthly, preparing a precursor material; sixthly, cooling; seventhly, the method comprises the following steps: preparing the gradient fluorine-doped ternary cathode material. The content change of Ni and F in the gradient fluorine-doped ternary cathode material is in reverse gradient change, the lattice stress is reduced, and the cycle performance and the rate capability are improved. |
