| titleOfInvention | Lithium ion solid-state battery positive active material precursor and preparation method and application thereof |
| abstract | The invention provides a precursor of a positive active material of a lithium ion solid-state battery, a preparation method and application thereof, belonging to the technical field of lithium battery materials, and the preparation method of the precursor of the positive active material of the lithium ion solid-state battery comprises the following steps: mixing the nickel-cobalt-manganese hydroxide suspension, the dilute alkali solution and the soluble aluminum salt solution, adjusting the pH of the mixed solution to 8.5-12, and fully stirring to obtain a coating A; mixing the coating A, a dilute alkali solution and a soluble cobalt salt solution, adjusting the pH of the mixed solution to 8.5-12, and fully stirring to obtain a coating B; spraying a concentrated alkali solution into the coating B with the material temperature of 80-120 ℃ in a spraying manner under the condition of continuous stirring, and preserving the temperature until the material is dried to obtain the precursor of the positive active material of the lithium ion solid-state battery. The method has simple process route and low production cost, and is suitable for large-scale industrial production. The surface of the precursor of the positive active material of the lithium ion solid-state battery is provided with a uniform gamma-AlOOH and gamma-CoOOH double-coating layer, so that the stability is good, and the electrochemical performance is excellent. |
