Abstract
Provided is a stacked electrode body the whole of which can be checked for misregistration. A stacked electrode body for an all-solid-state battery includes a plurality of electrode bodies that are stacked and each includes a first electrode, a solid electrolyte layer, a second electrode, and a second current collector which are disposed on each of both surfaces of a first current collector in this order, wherein each of the electrode bodies has a protrusion protruding outward from a side face thereof, and the protrusions have phase differences in a stacking direction.

A stacked electrode body for an all-solid-state battery, the stacked electrode body including a plurality of electrode bodies that are stacked, the electrode bodies each including a first electrode, a solid electrolyte layer, a second electrode, and a second current collector which are disposed on each of both surfaces of a first current collector in an order mentioned, wherein
- each of the electrode bodies has a protrusion protruding outward from a side face thereof, and
- the protrusions have phase differences in a stacking direction,
- each of the electrode bodies has an extending portion including the first electrode, the extending portion extending further than a side face of the second electrode, and
- each of the protrusions is formed on part of the extending portion, the protrusion being a portion protruding further than another part of the extending portion, and
- the phase difference portion and the protrusion comprise the first current collector, the first electrode, and the solid electrolyte layer.
