| titleOfInvention | Niobium-phosphorus co-doped high-nickel ternary cathode material and preparation method and application thereof |
| abstract | The invention belongs to the technical field of lithium ion battery anode materials, and particularly relates to a niobium-phosphorus co-doped high-nickel ternary anode material as well as a preparation method and application thereof. The method comprises the following steps: (1) preparing soluble nickel salt, cobalt salt and manganese salt into mixed salt solution according to a set proportion, then dropwise adding the mixed salt solution and a precipitator, and adjusting the concentration of nickel ions in the supernatant by ammonia water in the dropwise adding process to prepare a nickel-cobalt-manganese precursor; (2) mixing the precursor obtained in the step (1) with a phosphorus source to obtain A, mixing the A with a lithium source, and then carrying out plasma roasting to obtain a phosphorus-doped high-nickel ternary cathode material; (3) and (3) mixing a niobium source with the phosphorus-doped high-nickel ternary cathode material obtained in the step (2), and then carrying out plasma roasting to obtain the niobium-phosphorus co-doped high-nickel ternary cathode material. According to the invention, lithium and oxygen sites are directionally doped by metal-nonmetal elements, so that the problems of crystal structure and removal of lithium residues on the surface of the material are effectively solved. |
