Abstract
A solid state battery that includes: a solid state battery laminate having a stacked portion that includes a positive electrode layer, a negative electrode layer, and a solid electrolyte interposed between the positive electrode layer and the negative electrode layer; and a moisture absorbing film contacting at least a part of the solid state battery laminate and integrated with the solid state battery laminate.
Claims17
A solid state battery, comprising:
- a solid state battery laminate having a stacked portion that includes a positive electrode layer, a negative electrode layer, and a solid electrolyte layer interposed between the positive electrode layer and the negative electrode layer;
- an external terminal on a side surface of the stacked portion in a direction intersecting a stacking direction of the positive electrode layer, the negative electrode layer, and the solid electrolyte layer;
- a moisture absorbing film on at least a part of a surface of the external terminal;
- and
- an insulating film covering the laminate, at least part of the external terminal, and the moisture-absorbing film,
- wherein the moisture absorbing film is positioned between the insulating film and the external terminal.

A solid state battery, comprising:
- a solid state battery laminate having a stacked portion that includes a positive electrode layer, a negative electrode layer, and a solid electrolyte layer interposed between the positive electrode layer and the negative electrode layer;
- and
- a moisture absorbing film contacting at least a part of the solid state battery laminate and integrated with the solid state battery laminate,
- wherein the moisture absorbing film covers a side surface of the stacked portion located in a direction intersecting a stacking direction of the positive electrode layer, the negative electrode layer, and the solid electrolyte layer,
- wherein the solid state battery laminate further includes an external terminal on the side surface of the stacked portion in the direction intersecting the stacking direction, and the moisture absorbing film covers the external terminal, such that the moisture absorbing film is disposed outside of the external terminal, and
- wherein the moisture absorbing film extends in the direction intersecting the stacking direction to cover an interface between the external terminal and the stacked portion in a side sectional view of the solid state battery.
