Functional metal oxide powders (LiCoO2, LiFePO4, SrTi1-xCoxO3) have been synthesized by a novel Electric Discharge Assisted Mechanical Milling (EDAMM) processing technique. Characterisation of the as-synthesized powders by XRD, SEM, and TEM confirm near pure phases with a highly controllable morphology can be produced in only minutes. The electrochemical (LiCoO2, LiFePO4) and magnetic (SrTi1-xCoxO3) behaviour of the powders indicates functionality that at least matches that of powders synthesized by traditional solid-state approaches. The EDAMM technique provides significant commercial opportunities as the method has proven to be scalable and powder morphologies can be made to order.
