| titleOfInvention | Nickel-based positive electrode material, precursor thereof, and preparation methods of nickel-based positive electrode material and precursor |
| abstract | The invention discloses a nickel-based anode material, a precursor thereof and a preparation method of the material and the precursor, wherein the general formula of the nickel-based precursor is Ni x M 1‑x O(OH) y (0.5<x is less than or equal to 1, and y is less than or equal to 1 and less than or equal to 2); the general formula of the nickel-based cathode material is Li z Ni x M 1‑x O 2 (0.5<x≤1、0.9<z<1.2). The preparation method comprises the following steps: simultaneously adding a mixed solution prepared from nickel salt and soluble salt of M element, a precipitant mixed solution and a buffer solution into a reaction kettle, controlling the reaction conditions to obtain a coprecipitate, regulating and controlling the pH value of the solution to be 7.0-14.0 and the potential value of the solution to be 0-1.0V, stirring and fully reacting to obtain a nickel-based precursor Ni x M 1‑x O(OH) y And uniformly mixing the nickel-based precursor with a lithium source compound, and calcining in an oxygen-containing atmosphere to obtain the nickel-based positive electrode material. The invention is used in lithium ion battery, under 0.2C multiplying power, the capacity retention rate of 200 cycles can reach more than 95%, and the specific discharge capacity under 2.0C multiplying power can reach more than 90% under 0.2C multiplying power. |
