Nickel oxide particles and method for producing the same

Abstract

Nickel oxide particles contain molybdenum. In the nickel oxide particles, the molybdenum may be unevenly distributed in a surface layer of the nickel oxide particles. A crystallite diameter of a [100] plane of the nickel oxide particles may be 240 nm or more. A crystallite diameter of a [101] plane of the nickel oxide particles may be 220 nm or more. A median diameter D50 of the nickel oxide particles calculated by a laser diffraction/scattering method may be 10.00 μm or more and 1000.00 μm or less. A method for producing the nickel oxide particles includes calcining a nickel compound in presence of a molybdenum compound. The molybdenum compound may be at least one compound selected from a group including molybdenum trioxide, lithium molybdate, potassium molybdate and sodium molybdate. In the method for producing the nickel oxide particles, a calcination temperature may be 800° C. or higher and 1600° C. or lower.
