Title (EN) METHOD FOR PRODUCING LGPS-BASED SOLID ELECTROLYTE
(FR) PROCÉDÉ DE PRODUCTION D'UN ÉLECTROLYTE SOLIDE À BASE DE LGPS
(JA) LGPS系固体電解質の製造方法
Abstract:
(EN) According to the present invention, a method for producing an LGPS-based solid electrolyte can be provided, the method being characterized by comprising: a solutionization step for preparing a homogeneous solution by mixing and reacting Li2S and P2S5 in an organic solution such that the molar ratio of Li2S/P2S5 is 1.0-1.85; a precipitation step for forming a precipitate by adding, to the homogeneous solution, at least one MS2 (M is selected from the group consisting of Ge, Si, and Sn.) and Li2S and then mixing; a drying step for obtaining a precursor by removing the organic solution from the precipitate; and a heating treatment step for obtaining the LGPS-based solid electrolyte by heating the precursor at 200-700°C.
(FR) La présente invention concerne un procédé de production d'un électrolyte solide à base de LGPS, le procédé étant caractérisé en ce qu'il comprend : une étape de mise en solution consistant à préparer une solution homogène par mélange et réaction de Li2S et de P2S5 dans une solution organique de telle sorte que le rapport molaire de Li2S/P2S5 soit de 1,0 à 1,85 ; une étape de précipitation consistant à former un précipité par ajout, à la solution homogène, d'au moins un MS2 (où M est choisi dans le groupe constitué par le Ge, le Si, et le Sn) et du Li2S, suivi d'un mélange ; une étape de séchage consistant à obtenir un précurseur par élimination de la solution organique du précipité ; et une étape de traitement thermique pour obtenir l'électrolyte solide à base de LGPS par chauffage du précurseur à 200-700 °C.
(JA) 本発明によれば、LiSとPとをLiS/P=1.0~1.85のモル比となるように有機溶媒中で混合して反応させることによって均一溶液を調製する溶液化工程と、前記均一溶液に少なくとも1種のMS(MはGe、Si及びSnからなる群より選ばれる)とLiSとを添加して混合し、沈殿を形成する沈殿化工程と、前記沈殿から前記有機溶媒を除去して前駆体を得る乾燥工程と、前記前駆体を200~700℃にて加熱処理してLGPS系固体電解質を得る加熱処理工程と、を含むことを特徴とするLGPS系固体電解質の製造方法を提供することができる。
