Abstract
Provided is a solid-state battery having a bipolar electrode plate and capable of reducing the lamination space factor of a solid electrolyte and reducing electrical resistivity. The solid-state battery includes: a laminate including a positive electrode plate, at least one bipolar electrode plate, and a negative electrode plate that are laminated; and a solid electrolyte layer formed on a lamination surface of the at least bipolar electrode plate.
Claims6
A solid-state battery comprising:
- a laminate including a positive electrode plate, a plurality of bipolar electrode plates, and a negative electrode plate that are laminated;
- and
- a solid electrolyte layer formed on a lamination surface of each of the plurality of bipolar electrode plates, wherein
- each of the plurality of bipolar electrode plates has, on an end face thereof as viewed from a lamination surface side, a concave portion on which the solid electrolyte layer is formed and a convex portion on which the solid electrolyte layer is not formed, the concave portion and the convex portion being alternately formed,
- adjacent ones of the plurality of bipolar electrode plates have shapes that are mutually in a mirror-image relation, and
- the concave portion and the convex portion are arranged to be staggered between adjacent ones of the plurality of bipolar electrode plates.
