Abstract
Official abstract text for this publication.
A method for producing a lithium-nickel complex oxide according to an aspect of the present disclosure comprises: a filling step for filling a firing container with a Ni-containing metal compound and a Li compound to obtain a filling material including the Ni-containing metal compound and the Li compound; and a firing step for firing the filling material that fills the firing container, wherein, in the filling step, when the filling material that fills the firing container is divided into two equal parts in the height direction, the molar ratio A of Li to metals other than Li in the filling material in the upper half region and the molar ratio B of Li to metals other than Li in the filling material in the lower half region satisfy 1<B/A<1.15.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A method for manufacturing a lithium-nickel composite oxide, the method comprising: a filling step of filling a firing container with a Ni-containing metal compound and a Li compound to obtain a filling material including the Ni-containing metal compound and the Li compound; and a firing step of firing the filling material filling the firing container, wherein in the filling step, the filling material filling the firing container has an upper half region and a lower half region that are equal in height, and a molar ratio A of Li to metals other than Li in the filling material in the upper half region and a molar ratio B of Li to metals other than Li in the filling material in the lower half region satisfy 1<B/A<1.15. 2 . The method for manufacturing a lithium-nickel composite oxide according to claim 1 , wherein the molar ratio A and the molar ratio B satisfy 1.02≤B/A≤1.12. 3 . The method for manufacturing a lithium-nickel composite oxide according to claim 1 , wherein the Li compound contains lithium hydroxide.
