Stacked electrode body, resin-fixed stacked electrode body, and all-solid-state battery
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.
1. 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.
2. A resin-fixed stacked electrode body formed by fixing the side face of the stacked electrode body according to claim 1 with resin.
3. An all-solid-state battery having the resin-fixed stacked electrode body according to claim 2 .
