| titleOfInvention | Method for producing lithium metal composite oxide having layer structure |
| abstract | The present invention relates to a method for producing a lithium metal composite oxide having a layer structure, which can effectively reduce an unreacted lithium compound remaining in the lithium metal composite oxide. A method for producing a lithium metal composite oxide having a layer structure is proposed, which is represented by the general formula (1): li 1+x Ni 1‑α‑β‑γ Mn α Co β M γ O 2 (wherein x is 0. ltoreq. x.ltoreq.0.1, α is 0.01. ltoreq. α is 0.35, β is 0.35, and γ is 0. ltoreq. γ.ltoreq.0.1. M contains at least 1 or more elements selected from the group consisting of Al, Mg, Ti, Fe, Zr, W, and Nb). The method for producing a lithium metal composite oxide (B) having a layer structure comprises a first step of pre-baking at 400 to 850 ℃ to obtain a lithium metal composite oxide (B) having a general formula (2) in which Li is represented by 1+ x Ni 1‑α‑β‑γ Mn α Co β M γ O 2 (wherein-0.7. ltoreq. x.ltoreq.0.05, 0.01. ltoreq. α. ltoreq.0.35, 0.01. ltoreq. β. ltoreq.0.35, and 0. ltoreq. gamma. ltoreq.0.1. M comprises at least 1 or more elements selected from the group consisting of Al, Mg, Ti, Fe, Zr, W, and Nb), and (2) a step of mixing the lithium metal composite oxide (A) obtained in the step 1 with a lithium compound and subjecting the mixture to main firing at 700 ℃ to 1000 ℃ to obtain the lithium metal composite oxide (B). |
