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.
Claims8
A solid-state battery comprising:
- 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 one bipolar electrode plate.
A method of manufacturing a solid-state battery, the method including a bipolar electrode plate producing process,
- the bipolar electrode plate producing process comprising, in sequence:
- an electrode material coating step of coating one surface of a current collecting plate with a positive electrode material and coating the other surface of the current collecting plate with a negative electrode material;
- a perforating step of forming a hole in a part of the current collecting plate coated with the positive and negative electrode materials;
- a solid electrolyte coating step of coating, with a solid electrolyte, the current collecting plate coated with the positive and negative electrode materials;
- and
- a cutting step of cutting the current collecting plate coated with the positive and negative electrode materials along a cutting line extending across the hole so that a concave portion is formed at an edge of the current collecting plate.
