PROBLEM TO BE SOLVED: To provide an electrode active material for a nonaqueous electrolyte battery excellent in a charge/discharge capacity. SOLUTION: In a method obtaining a lithium-nickel compound oxide represented by a formula Lix Niy Nz O2 (0.8<x<1.2, 0.8<y+z<1.2, 0<=z<0.2) by burning a mixture of a lithium compound, nickel compound and an N compound (N is element except Li, Ni, 0) with a burning furnace used, gas of 0.01vol.% or less carbon dioxide -20 deg.C or less water dew point is supplied in the concerned burning furnace, at a gas supply speed at least five times the amount equivalent to the internal volume of the burning furnace is supplied within one hour. |
