| titleOfInvention | Phosphorus-doped lithium-rich manganese-based positive electrode material for lithium ion battery and preparation method thereof |
| abstract | The invention discloses a preparation method of a phosphorus-doped lithium-rich manganese-based positive electrode material for a lithium ion battery, which specifically comprises the steps of preparing a precipitator solution, preparing a metal salt solution, preparing a phosphorus-doped nickel-cobalt-manganese carbonate precursor and preparing the phosphorus-doped lithium-rich manganese-based positive electrode material; dissolving a pyrophosphoric acid compound serving as a phosphorus source in a precipitator solution, obtaining a phosphorus-doped nickel-cobalt-manganese compound precursor by adopting a coprecipitation method, and finally obtaining the phosphorus-doped lithium-rich manganese-based positive electrode material by high-temperature sintering; the preparation method disclosed by the invention is simple, and the prepared anode material is not only doped with phosphorus on the surface, but also uniformly doped with phosphorus in the material, so that the material is stable in performance and long in service life, and meanwhile, the capacity, the first effect, the multiplying power and the cycling stability of the material are obviously improved. |
