Title: (DE) DÜNNFILMBATTERIEN MIT WEICHEN UND HARTEN ELEKTROLYTSCHICHTEN
(EN) THIN-FILM BATTERIES WITH SOFT AND HARD ELECTROLYTE LAYERS
(FR) BATTERIES À COUCHES MINCES AVEC COUCHES ÉLECTROLYTIQUES MOLLES ET DURES
Abstract: front page image
(EN) A method and apparatus for making thin-film batteries having composite multi-layered electrolytes with soft electrolyte between hard electrolyte covering the negative and/or positive electrode, and the resulting batteries. In some embodiments, foil-core cathode sheets each having a cathode material (e.g., LiCoO2) covered by a hard electrolyte on both sides, and foil-core anode sheets having an anode material (e.g., lithium metal) covered by a hard electrolyte on both sides, are laminated using a soft (e.g., polymer gel) electrolyte sandwiched between alternating cathode and anode sheets. A hard glass-like electrolyte layer obtains a smooth hard positive-electrode lithium-metal layer upon charging, but when very thin, have randomly spaced pinholes/defects. When the hard layers are formed on both the positive and negative electrodes, one electrode's dendrite-short-causing defects on are not aligned with the other electrode's defects. The soft electrolyte layer both conducts ions across the gap between hard electrolyte layers and fills pinholes.
(FR) La présente invention concerne un procédé et un appareil pour fabriquer des batteries à couches minces comportant des électrolytes à couches multiples composites avec un électrolyte mou entre un électrolyte dur couvrant l’électrode négative et/ou positive, et les batteries résultantes. Dans certains modes de réalisation, des plaques cathodiques à noyau en feuille comportant chacune un matériau de cathode (par exemple, LiCoO2) couvert d’un électrolyte dur sur les deux côtés, et des plaques anodiques à noyau en feuille comportant un matériau d’anode (par exemple, du lithium métallique) couvert d’un électrolyte dur sur les deux côtés, sont stratifiées en utilisant un électrolyte mou (par exemple, un gel polymère) intercalé entre des plaques cathodiques et anodiques alternées. Une couche d’électrolyte de type verre dur obtient une couche métallique en lithium d’électrode positive dure uniforme lors de la charge, mais lorsqu’elle est très mince, présente des trous d’épingle/défauts espacés de manière aléatoire. Lorsque les couches dures sont formées sur les électrodes positives et négatives à la fois, des défauts entraînant un court-circuit par croissance dendritique d’une électrode ne sont pas alignés avec les défauts de l’autre électrode. La couche électrolytique molle conduit des ions à travers l’espace entre les couches électrolytiques dures et remplit les trous d’épingle en même temps.
