    Abstract: Disclosed is a thin film lithium battery which realizes a high yield by solving various problems caused by generation of pinholes in a solid electrolyte layer. Specifically disclosed is a thin film lithium battery wherein a positive electrode layer (20), a negative electrode layer (50), a solid electrolyte layer (40) arranged between the electrode layers, and a collector (10) electrically connected to one or both of the positive electro de layer (20) and the negative electrode layer (50) are arranged in layers. Whe n the lamination of the layers in this battery is viewed in plan, the positive electrode layer (20) and the negative electrode layer (50) are arranged not to overlap each other. By having such a structure, even when a pinhole is forme d in the solid electrolyte layer (40), the electrode layers (20, 50) are prevented from being short-circuited by the pinhole.

    Abstract: A thin film lithium battery is provided which can realize a high yield by solving various problems caused by a pin hole formed in a solid electrolyte layer. A thin film lithium battery according to the present invention is a thin film lithium battery in which a positive electrode layer 20, a negative electrode layer 50, a solid electrolyte layer 40 provided therebetween, and a collector 10 electrically connected to at least one of the positive electrode layer 20 and the negative electrode layer 50 are laminated to each other. When this battery is viewed in plan along the lamination direction of the above individual layers, the positive electrode layer 20 and the negative electrode layer 50 are disposed at positions so as not to be overlapped with each other. By the structure as described above, even if a pin hole is formed in the solid electrolyte layer 40, short-circuiting between the two electrode layers 20 and 50, which is caused by this pin hole, can be prevented.

    Abstract: Es wird ein positiver Elektrodenkörper für eine nichtwässrige Elektrolytbatterie vorgesehen, worin die Bildung von Hochresistenzschichten an den Kontaktgrenzflächen zwischen Aktivmaterialien für die positive Elektrode und Fest-Elektrolytteilchen unterdrückt wird, so dass eine Erhöhung der Grenzflächenresistenz unterdrückt wird. Ein positiver Elektrodenkörper 1 für eine nichtwässrige Elektrolytbatterie gemäß dieser Erfindung umfasst eine Mischung aus Sulfid-Fest-Elektrolytteilchen 11 und abgedeckten Aktivmaterialteilchen 10 für die positive Elektrode, worin Oberflächen der Aktivmaterialteilchen 10a für die positive Elektrode mit Abdeckschichten 10b mit Li-Ionen-Leitfähigkeit abgedeckt sind. Die Abdeckschichten 10b sind aus einem amorphen Oxid mit Sauerstoffmangel gebildet. Die Abdeckschichten 10b haben Sauerstoffmangel und als Ergebnis kann eine Li-Ionen-Leitfähigkeit und Elektronenleitfähigkeit stabil in den Abdeckschichten 10b sichergestellt werden, die für die Ladung und Entladung der Batterie ausreichend sind.

    Abstract: The battery of the invention has a positive-electrode layer 20, a negative-electrode layer 50, and an electrolytic layer 40 through which ionic conduction is performed between the two electrode layers. In this battery, the positive-electrode layer 20 and the negative-electrode layer 50 are laminated with each other and an insulating layer 30 is placed between the positive-electrode layer 20 and the negative-electrode layer 50. The insulating layer 30 has an area smaller than that of one of the positive-electrode layer 20 and the negative-electrode layer 50 and larger than that of the other. There is no place where the positive-electrode layer 20 and the negative-electrode layer 50 face each other through only the electrolytic layer 40. Even when the electrolytic layer 40 has a pinhole, the presence of the insulating layer 30 between the positive-electrode layer 20 and the negative-electrode layer 50 can suppress short-circuiting between the positive- and negative-electrode layers.
