Title (EN) METHOD FOR PRODUCING ELECTRODES FOR ALL-SOLID STATE BATTERIES
(FR) PROCÉDÉ DE PRODUCTION D'ÉLECTRODES POUR BATTERIES ENTIÈREMENT SOLIDES
Abstract:
(EN) A method (100) for producing a sintered component being an electrode including titanium and sulfur for an all-solid state battery, the method including mixing powders (102) so as to obtain a powder mixture comprising titanium and sulfur, pressing (106) a component with the powder mixture, sintering (108) the component under a partial pressure of sulfur comprised between 200 Pa and 0.2 MPa so as to obtain an intermediate sintered component comprising titanium and sulfur, and sintering (114) the intermediate sintered component under a partial pressure of sulfur equal to or smaller than 150 Pa at a temperature plateau comprised between 200°C and 400°C so as to obtain a sintered component comprising titanium and sulfur, the solid electrolyte exhibiting the peaks in positions of 2Θ = 15.08° (±0.50°), 15.28° (±0.50°), 15.92° (±0.50°), 17.5° (±0.50°), 18.24° (±0.50°), 20.30° (±0.50°), 23.44° (±0.50°), 24.48° (±0.50°), and 26.66° (±0.50°) in a X-ray diffraction measurement using CuKa line.
(FR) L'invention concerne un procédé (100) permettant de produire un composant fritté étant une électrode comprenant du titane et du soufre pour une batterie entièrement solide. Le procédé consiste à mélanger des poudres (102) de façon à obtenir un mélange de poudres comprenant du titane et du soufre, à presser (106) un composant avec le mélange de poudres, à fritter (108) le composant sous une pression partielle de soufre comprise entre 200 Pa et 0,2 MPa de manière à obtenir un composant fritté intermédiaire comprenant du titane et du soufre, et à fritter (114) le composant fritté intermédiaire sous une pression partielle de soufre égale ou inférieure à 150 Pa à un palier de température compris entre 200 °C et 400 °C de manière à obtenir un composant fritté comprenant du titane et du soufre, l'électrolyte solide présentant les pics dans des positions de 2Θ = 15,08° (±0,50°), 15,28° (±0,50°), 15,92° (±0,50°), 17,5° (±0,50°), 18,24° (±0,50°), 20,30° (±0,50°), 23,44° (±0,50°), 24,48° (±0,50°) et 26,66° (±0,50°) dans une mesure de diffraction des rayons X au moyen d'une ligne CuKa.
