Title (EN) METHODS OF MAKING AND INSPECTING A WEB OF VITREOUS LITHIUM SULFIDE SEPARATOR SHEET AND LITHIUM ELECTRODE ASSEMBLIES
(FR) PROCÉDÉS DE FABRICATION ET D'INSPECTION D'UNE BANDE DE FEUILLE VITREUSE DE SÉPARATION À BASE DE SULFURE DE LITHIUM ET ENSEMBLES ÉLECTRODE AU LITHIUM
Abstract:
(EN) A lithium ion-conductive solid electrolyte including a freestanding inorganic vitreous sheet of sulfide-based lithium ion conducting glass is capable of high performance in a lithium metal battery by providing a high degree of lithium ion conductivity while being highly resistant to the initiation and/or propagation of lithium dendrites. Such an electrolyte is also itself manufacturable, and readily adaptable for battery cell and cell component manufacture, in a cost-effective, scalable manner. An automated machine based system, apparatus and methods assessing and inspecting the quality of such vitreous solid electrolyte sheets, electrode sub-assemblies and lithium electrode assemblies can be based on spectrophotometry and can be performed inline with fabricating the sheet or web (e.g., inline with drawing of the vitreous Li ion conducting glass) and/or with the manufacturing of associated electrode subassemblies and lithium electrode assemblies and battery cells.
(FR) La présente invention concerne un électrolyte solide conducteur d'ions de lithium comprenant une feuille vitreuse inorganique amovible composée d'un verre soufré conducteur d'ions de lithium, ledit électrolyte pouvant être très performant dans une batterie au lithium-métal en offrant un degré élevé de conductivité d'ion de lithium tout en étant très résistant à l'initiation et/ou à la propagation des dendrites de lithium. Un tel électrolyte peut également être lui-même fabriqué et être facilement adapté à la fabrication d'une cellule de batterie et d'un composant de cellule, à un coût avantageux et de manière évolutive. Un système à base de machine automatique, un appareil et des procédés permettant d'évaluer et d'inspecter la qualité de ces feuilles vitreuses d'électrolyte solide, de sous-ensembles d'électrode et d'ensembles électrode au lithium peuvent être basés sur la spectrophotométrie et peuvent être effectués en ligne avec la fabrication de la feuille ou de la bande (par exemple, en ligne avec le tirage du verre vitreux conducteur d'ion de Li) et/ou avec la fabrication de sous-ensembles d'électrode associés et d'ensembles d'électrode au lithium et de cellules de batterie.
