Abstract: A process for processing an electroactive mesoporous material into a cathode, or an anode or a supercapacitor material using one or more of the steps of: (a) modifying the material to remove impurities or substitute materials in the powder by a hydrothermal process; (b) intercalating the material by injecting the material with the charge carrier ion using a hydrothermal process or supercritical CO2 fluid process where the solvent fluid contains a soluble material of the charge carrier ion; (c) sintering the intercalated material; (d) providing a layer of a conducting material within the material pores; (e) filling the pores and interparticle spaces with an electrolyte generally comprising the charge carrier ion and a solvent; and for solid state materials, (f) polymerizing the solvent to encapsulate the powders.

Abstract: A method for heating a powder material to induce a crystalline phase change in the grains of the particle comprising the steps of: a. preheating the powder from the high temperature streams generated from cooling the phase changed product; b. injecting the powder into a metal tube; c. controlling the gas composition in the metal tube by injecting a gas into the reactor; d. externally heating the first section of the tube by a first furnace segment system; e. externally heating the second section of the tube by a second furnace segment system; f: quickly quenching the powder product temperature in a cold third segment of the tube; g. collecting the processed powder at the base of the tube in a bed ejecting the powder from the tube; h. cooling the powder in a heat exchanger and using the heat to preheat the powder in step a.
