| titleOfInvention | A layered large particle size high nickel single crystal ternary positive electrode material and preparation method thereof |
| abstract | The invention relates to a layered large particle size high nickel single crystal ternary positive electrode material and a preparation method thereof. The preparation method includes the following steps: weighing nickel salt, cobalt salt, manganese salt, and strontium salt and dispersing them into pure water to obtain a precursor solution; atomizing and decomposing the precursor solution to obtain a precursor powder; The powder is heat-treated, and then the heat-treated precursor powder, the first lithium source, and zirconia are fully mixed, followed by heating and melting, and one-time sintering to obtain a single-crystal ternary material; the single-crystal ternary material is air-milled, washed with water and filtered 2. After drying, add a second lithium source, continue to mix uniformly, and obtain a layered large-diameter high-nickel single crystal ternary positive electrode material through secondary sintering. The layered large particle size high nickel single crystal ternary positive electrode material obtained by the invention has higher particle size and lower specific surface area, can effectively reduce side reactions, and improve battery capacity and cycle performance. |
