Title
(EN) OPTIMISATION OF MESOPOROUS BATTERY AND SUPERCAPACITOR MATERIALS
(FR) OPTIMISATION DE MATÉRIAUX MÉSOPOREUX DE BATTERIES ET DE SUPERCONDENSATEURS
Abstract
(EN) 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.
(FR) Procédé de transformation d'un matériau mésoporeux électroactif en une cathode, ou en une anode ou en un matériau de supercondensateur, à l'aide d'une ou plusieurs étapes parmi les étapes suivantes consistant : (a) à modifier le matériau afin d'éliminer les impuretés ou de substituer des matériaux dans la poudre au moyen d'un procédé hydrothermique ; (b) à intercaler le matériau au moyen de l'injection au matériau d'un ion porteur de charge à l'aide d'un procédé hydrothermique ou d'un procédé à fluide CO2 supercritique dans lequel le fluide solvant contient un matériau soluble de l'ion porteur de charge ; (c) à fritter le matériau intercalé ; (d) à placer une couche d'un matériau conducteur à l'intérieur des pores du matériau ; (e) à remplir les pores, et les espaces entre particules, d'un électrolyte comprenant généralement l'ion porteur de charge et un solvant ; et, pour des matériaux à l'état solide, (f) à polymériser le solvant pour encapsuler les poudres.
