Embodiment 1
[0031] Embodiment 1 of the preparation method of the composite ternary positive electrode material of the present invention adopts the following steps:
[0032] 1) Primary low-temperature sintering: Mix lithium hydroxide monohydrate and the precursor evenly, the molar amount of Li in lithium hydroxide monohydrate is 1.1 times the sum of the molar amounts of Ni, Co, and Mn in the precursor, and then Sinter in dry air at 700°C for 20 hours, and cool down to room temperature naturally; after sintering, crush it through a 300-mesh sieve to obtain a primary sintered product.
[0033] 2) Secondary high-temperature sintering: mix the primary sintered product and additive KCl evenly, the mass of KCl is 0.1% of the mass of the primary sintered product, then sinter in an atmosphere furnace in dry air at 900°C for 15 hours, and cool down to room temperature naturally ; After the sintering is completed, it is crushed by air flow and passed through a 300-mesh screen to obtain a secondary s...
