Abstract
There is provided a bipolar laminated all-solid-state lithium-ion rechargeable battery including bipolar electrodes and solid electrolyte layers that are alternately laminated. When viewed from a lamination direction of the battery, a current collector layer of each bipolar electrode has its outer edge inside the outer edge of a positive electrode layer and a negative electrode layer of the bipolar electrode. At least one of the positive electrode layer and the negative electrode layer of each bipolar electrode is provided with at least one electrical insulating portion in an outer edge region on the surface where it is in contact with the current collector layer of the bipolar electrode. When each bipolar electrode is viewed from the lamination direction, the perspective projection of the at least one electrical insulating portion configures the entire periphery of the outer edge. The bipolar electrodes and the solid electrolyte layers form a sinter-bonded body.
