Abstract

A battery includes a supporting substrate, resin layers, and a plurality of cells. Each resin layer includes a first resin and has 0.5 MPa to 10 MPa in tensile strength. The cells are stacked on the supporting substrate with the resin layers between the cells.

First claim

What is claimed is:

1. A battery comprising:
a supporting substrate;
resin layers each including a first resin and having 0.5 MPa to 10 MPa in tensile strength; and
a plurality of cells that are stacked on the supporting substrate with the resin layers between the cells,
wherein one of the cells is stacked on another one of the cells such that a portion of said another one of the cells is exposed from the one of the cells,
each of the cells is electrically connected to an adjacent one of the cells via a wire, and
each of the cells and wires is covered by a second resin having 0.5 MPa to 10 MPa in tensile strength.

2. The battery according to claim 1 , further comprising:
a member that is supported by the supporting substrate and that covers above the stacked cells.

3. The battery according to claim 1 , wherein
each of the cells comprises a substrate and an electrolyte layer provided above an upper surface of the substrate, and
a lower surface of the substrate of a first cell of the plurality of cells is located above an upper surface of the electrolyte layer of a second cell of the plurality of cells.

4. A battery comprising:
a supporting substrate;
resin layers each including a first resin;
a plurality of cells that are stacked on the supporting substrate with the resin layers between the cells; and
a bonding layer that fixes the stacked cells to the supporting substrate, wherein
the resin layers have a smaller tensile strength than the bonding layer,
each of the cells is electrically connected to an adjacent one of the cells via a wire, and
each of the cells and wires is covered by a second resin having a smaller tensile strength than the bonding layer.

5. The battery according to claim 4 , wherein
the resin layers have 0.5 MPa to 10 MPa in tensile strength, and
the bonding layer has 50 MPa or more in tensile strength.

6. The battery according to claim 4 , further comprising:
a member that is supported by the supporting substrate and that covers above the stacked cells.

7. The battery according to claim 4 , wherein one of the cells is stacked on another one of the cells so that the one cell and said another cell entirely overlap each other in plan view.

8. The battery according to claim 4 , wherein
each of the cells comprises a substrate and an electrolyte layer provided above an upper surface of the substrate, and
a lower surface of the substrate of a first cell of the plurality of cells is located above an upper surface of the electrolyte layer of a second cell of the plurality of cells.

9. A battery comprising:
a supporting substrate;
resin layers each including a first resin;
a plurality of cells that are stacked on the supporting substrate with the resin layers between the cells; and
a bonding layer that fixes the stacked cells to the supporting substrate,
wherein the resin layers have a smaller tensile strength than the bonding layer,
wherein one of the cells is stacked on another one of the cells such that the one cell and said another cell partially overlap each other in plan view,
wherein each of the cells is electrically connected to an adjacent one of the cells via a wire, and
wherein each of the cells and wires is covered by a second resin having a smaller tensile strength than the bonding layer.

10. The battery according to claim 9 , wherein
the resin layers have 0.5 MPa to 10 MPa in tensile strength, and
the bonding layer has 50 MPa or more in tensile strength.

11. The battery according to claim 9 , further comprising:
a member that is supported by the supporting substrate and that covers above the stacked cells.

12. The battery according to claim 9 , wherein
each of the cells comprises a substrate and an electrolyte layer provided above an upper surface of the substrate, and
a lower surface of the substrate of a first cell of the plurality of cells is located above an upper surface of the electrolyte layer of a second cell of the plurality of cells.
