The process may include the steps of Selecting an precursor material that, upon heating in a gas stream, releases volatile compounds to create porous materials to generate a material compound suitable for an electrode in an ion battery. Grinding the precursor material to produce a powder of particles with a first predetermined particle size distribution to form a precursor powder. Calcining the precursor powder in a flash calciner reactor segment with a first process gas at a first temperature to produce a porous particle material suitable for an electrode in an ion battery, and having the pore properties, surface area and nanoscale structures for applications in such batteries. Processing the hot precursor powder in a second calciner reactor segment with a second process gas to complete the calcination reaction, to anneal the material to optimise the particle strength, and to modify the oxidation state of the product for maximising the charge density when the particle is activated in a battery cell to form a second precursor powder. Quenching the second precursor powder. Activating the particles of the second precursor powder in an electrolytic cell by the initial charging steps to intercalate electrolyte ions in the particles.
