| titleOfInvention | A kind of cobalt nano-coating modified nickel-rich and low-cobalt single crystal multi-element cathode material and preparation method thereof |
| abstract | The invention discloses a nickel-rich and low-cobalt single-crystal multi-element positive electrode material modified by cobalt nano-coating, comprising a nickel-rich and low-cobalt single-crystal multi-element positive electrode material core and a nickel-rich and low-cobalt single crystal multi-element positive electrode material coated on the surface of the inner core. Cobalt nanocoating; wherein, the chemical formula of the nickel-rich and low-cobalt single crystal multi-element cathode material modified by cobalt nanocoating is Li x Ni a Co b Mn c M 1‑a‑b‑c O 2 ·yLCO; cobalt The nano-coating is obtained by reacting a cobalt source and a precipitant; in terms of Co, the mass of the cobalt source is 0.3%-6.0% of the inner core of the nickel-rich and low-cobalt single crystal multi-element cathode material. Preparation method: (1) weighing each raw material; (2) sintering; (3) cobalt coating; (4) heat treatment. In the present invention, the cobalt nano-coating is coated on the surface of the nickel-rich and low-cobalt single crystal multi-element positive electrode material, so as to improve the electronic conductivity of the nickel-rich and low-cobalt single crystal multi-element positive electrode material, reduce the internal resistance of the battery, and inhibit the phase change of the material in the process of multiple charging and discharging. change and improve the cycle performance of the cathode material. |
