Abstract: The present invention relates to a process for making an alkali metal oxyanion comprising iron. In one aspect of the invention, hydrothermal methods are used with a nanoscale iron precursor in order to provide desirably low particle size and high purity and crystallinity.

Abstract: A process for preparing an alkali metal oxyanion electrode material having a carbon coating deposited by a thermal treatment, said process comprising a thermal step under a humidified atmosphere of: (i) said alkali metal oxyanion electrode material having a carbon coating deposited by a thermal treatment; (ii) precursors of said alkali metal oxyanion electrode material and an organic precursor of carbon; or (iii) said alkali metal oxyanion electrode material and an organic precursor of carbon, wherein said thermal step is performed at a temperature in the range of about 300° C. to about 950° C.

Abstract: A process for preparing a formulation comprising a carbon-deposited lithium metal phosphate, as precursor of a lithium ion battery electrode coating slurry.
