Abstract (first 170 chars)

The present invention belongs to the field of battery materials, and relates to a process for preparing a particulate lithium manganese nickel spinel compound, and materials produced by the process. The process of the invention uses Mn-containing precursors, Ni-containing precursors, Li-containing precursors and optionally M-containing precursor which form substantially no NOx gases during calcination. The particulate lithium manganese nickel spinel compound product of the process may find use in a lithium ion battery.
