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 is 3 or less; mixing the composite oxide particles and a lithium compound to obtain a first mixture; subjecting the first mixture to a first heat treatment at a first temperature and a second heat treatment at a second temperature higher than the first temperature to obtain a first heat-treated product; and subjecting the first heat-treated material to a dispersion treatment.

Claim (Index 7):
The method according to  claim 1 , wherein the first temperature is in a range of 850\u00b0 C. to 950\u00b0 C., and the second temperature is in a range of 980\u00b0 C. to 1,100\u00b0 C.
