Embodiment 1
[0024] The present invention provides the following technical scheme: a method for preparing a composite coated lithium-ion battery ternary material, the specific process steps are as follows:
[0025] The ternary precursor Ni 0.8 co 0.15 mn 0.05 (OH) 2 Mix it with lithium hydroxide, where Li / Me=1.05, mix it with a high-speed mixer for 10 minutes, and then burn it at 800°C for 15 hours to obtain a nickel-cobalt-manganese ternary material. The obtained nickel-cobalt-manganese ternary material and Al(OH) 3 mixed, where Al(OH) 3 The molar ratio is 0.5mol%, and it is sintered at 550°C for 11 hours to obtain an oxidized coated ternary material. Coating ternary materials and LiAlO with oxide type 2 mixed, where LiAlO 2 The molar ratio is 0.2mol%, and it is sintered at 500°C for 10h to obtain a composite coated ternary material.

[0028] The present invention provides the following technical scheme: a method for preparing a composite coated lithium-ion battery ternary material, the specific process steps are as follows:
[0029] The ternary precursor Ni 0.83 co 0.1 mn 0.07 (OH) 2 Mix it with lithium hydroxide, where Li / Me=1.06, mix it with a high-speed mixer for 15 minutes, and then burn it at 805°C for 14 hours to obtain a nickel-cobalt-manganese ternary material. The obtained nickel-cobalt-manganese ternary material and Mg(OH) 2 mixed, where, Mg(OH) 2 The molar ratio is 0.5mol%, and sintered at 550°C for 12h to obtain an oxidized coated ternary material. Mix the oxidized coated ternary material with LiAlO2, where LiAlO 2 The molar ratio is 0.3mol%, and it is sintered at 500°C for 10h to obtain a composite coated ternary material.
Embodiment 3
[0031] The present invention provides the following technical scheme: a method for preparing a composite coated lithium-ion battery ternary material, the specific process steps are as follows:
[0032] The ternary precursor Ni 0.88 co 0.09 mn 0.03 (OH) 2 Mix it with lithium hydroxide, where Li / Me=1.06, mix it with a high-speed mixer for 15 minutes, and then burn it at 805°C for 14 hours to obtain a nickel-cobalt-manganese ternary material. The resulting nickel-cobalt-manganese ternary material and Zr(OH) 4 mixed, among them, Zr(OH) 4 The molar ratio of is 1mol%, and it is sintered at 600°C for 11h to obtain an oxidized coated ternary material. Coating ternary materials and LiZrO 2 mixed, where LiZrO 2 The molar ratio is 0.1mol%, and it is sintered at 450°C for 10h to obtain a composite coated ternary material.
