The lithium metal oxide powder includes 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 The median primary particle size is between micrometer and 3 micrometers, and the secondary particles have a porosity that is at least about 10%. Lithium metal oxide powders are particularly useful in making lithium ion batteries with improved performance when secondary particles are deagglomerated when forming cathodes used in lithium ion batteries.
