Abstract:
A method of producing a positive electrode active material for a nonaqueous electrolyte secondary battery, the method includes preparing nickel-containing composite oxide particles having a ratio  1 D 90 / 1 D 10  of a 90% particle size  1 D 90  to a 10% particle size  1 D 10  in volume-based cumulative particle size distribution of 3 or less; obtaining a raw material mixture containing the composite oxide particles and a lithium compound and having a ratio of a total number of moles of lithium to a total number of moles of metal elements contained in the composite oxide in a range of 1 to 1.3; subjecting the raw material mixture to a heat treatment to obtain a heat-treated material; subjecting the heat-treated material to a dry-dispersion treatment to obtain a first dispersion; and bringing the first dispersion into contact with a liquid medium to obtain a second dispersion.

Claim (Index 9):
The method according to  claim 1 , wherein the heat treatment of the raw material mixture is performed in an oxygen-containing atmosphere.
