Abstract: 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 ases during calcination. The particulate lithium manganese nickel spinel compound product of the process may find use in a lithium ion battery.

Abstract: The present invention provides carbon-coated lithium metal phosphate which is doped with aluminium such that the aluminium content is between 300 and 5000 ppm and which has a BET surface area of less than or equal to 15 m2/g. The carbon-coated lithium metal phosphate finds use as a cathode active material and provides improved electrochemical performance at low temperatures.
