Abstract

A solid-state battery that includes a solid-state battery laminate having a main surface configured as a circuit forming surface; and a circuit that controls the solid-state battery on the main surface.

First claim

1 . A solid-state battery comprising:
a solid-state battery laminate having a main surface configured as a circuit forming surface; and a circuit that controls the solid-state battery on the main surface.

2 . The solid-state battery according to claim 1 , wherein the main surface of the solid-state battery laminate is a support surface that supports the circuit that controls the solid-state battery.

3 . The solid-state battery according to claim 1 , wherein the circuit includes at least one circuit selected from a protective circuit, a charge control circuit, a temperature control circuit, an output compensation circuit, and/or an output stabilization power supply circuit.

4 . The solid-state battery according to claim 1 , wherein an input/output terminal electrode is on the main surface of the solid-state battery laminate.

5 . The solid-state battery according to claim 4 , wherein the input/output terminal electrode is a surface mount terminal.

6 . The solid-state battery according to claim 1 , wherein an input/output terminal electrode is on a side surface of the solid-state battery laminate.

7 . The solid-state battery according to claim 6 , wherein the input/output terminal electrode is a surface mount terminal.

8 . The solid-state battery according to claim 1 , wherein the main surface of the solid-state battery laminate is an insulating layer having ion insulation properties.

9 . The solid-state battery according to claim 8 , wherein the insulating layer contains ceramics.

10 . The solid-state battery according to claim 8 , wherein the solid-state battery laminate comprises an integrally sintered body that includes a positive electrode layer, a negative electrode layer, a solid electrolyte layer interposed between the positive electrode layer and the negative electrode layer, and the insulating layer.

11 . The solid-state battery according to claim 1 , wherein the solid-state battery is a packaged solid-state battery.

12 . The solid-state battery according to claim 1 , further comprising a covering insulating layer covering the circuit.

13 . The solid-state battery according to claim 12 , wherein the covering insulating layer is stacked on the main surface.

14 . The solid-state battery according to claim 12 , wherein the covering insulating layer contains a resin material.

15 . The solid-state battery according to claim 1 , wherein the solid-state battery is a surface-mounted battery.

16 . The solid-state battery according to claim 15 , wherein the main surface having the circuit is a non-mounting surface side of the surface-mounted battery.

17 . The solid-state battery according to claim 16 , wherein the main surface is a first main surface, the circuit is a first circuit, the solid-state battery laminate has a second main surface opposite the first main surface that is a mounting surface side of the surface-mounted battery, and the solid-state battery further comprises:
a second circuit that controls the solid-state battery on the second main surface.

18 . The solid-state battery according to claim 1 , wherein the main surface is a first main surface, the circuit is a first circuit, the solid-state battery laminate has a second main surface opposite the first main surface, and the solid-state battery further comprises:
a second circuit that controls the solid-state battery on the second main surface.

19 . The solid-state battery according to claim 10 , wherein the positive electrode layer and the negative electrode layer in the solid-state battery laminate are layers capable of occluding and releasing lithium ions.
