Abstract
Improved methods for preparing lithium transition metal oxide particulate such as lithium nickel metal cobalt oxide (“NMC”) for use in lithium batteries and other applications are disclosed. The lithium transition metal oxide particulate is prepared from appropriate transition metal oxide and Li compound precursors mainly using dry, solid state processes including dry impact milling and heating. Further, novel precursor particulates and novel methods for preparing precursor particles for this and other applications are disclosed.
