PROBLEM TO BE SOLVED: To provide a lithium metal oxide powder useful for producing a lithium ion battery having improved performance when secondary particles are deagglomerated when forming a cathode used in a lithium ion battery. To do. SOLUTION: The lithium metal oxide powder contains secondary particles composed of aggregated primary lithium metal oxide particles bonded together, and the primary lithium metal oxide particles are composed of Li, Ni, Mn, Co, and oxygen. , 0.1 micrometer to 3 micrometer medium primary particle size, the secondary particles have a pore ratio of at least about 10%.
