Abstract

Systems and/or techniques associated with a solid-state microbattery packaging system are provided. In one example, a device comprises a substrate layer and a tape substrate layer. The substrate layer is associated with a set of solid-state microbattery components. The tape substrate comprises a releasable adhesive material and a polymer sealing material. A conductive surface associated with the set of solid-state microbattery components is disposed on the releasable adhesive material of the tape substrate layer.

First claim

What is claimed is:

1. A device, comprising:
a substrate layer having a plurality of solid-state microbattery components disposed on a surface of the substrate layer; and
a tape substrate layer that comprises a releasable adhesive material, a first polymer sealing material and a second polymer sealing material, wherein a conductive surface associated with the plurality of solid-state microbattery components is disposed under the releasable adhesive material of the tape substrate layer;
a first cap wafer disposed on a first anode terminal of a first solid-state microbattery component of the plurality of solid-state microbattery components;
a second cap wafer disposed on a second anode terminal of a second solid-state microbattery component of the plurality of solid-state microbattery components, wherein the first cap wafer is a first component and the second cap wafer is a second component, the first cap wafer and the second cap wafer being separate components, and the first polymer sealing material bonds the first cap wafer and the substrate layer, and the second polymer sealing material bonds the second cap wafer and the substrate layer, wherein the second polymer sealing material is separate from the first polymer sealing material.

2. The device of claim 1 , wherein the first anode terminal and a first cathode terminal of the first solid-state microbattery component of the plurality of solid-state microbattery components are disposed within the first polymer sealing material of the tape substrate layer, and wherein the second anode terminal and a second cathode terminal of the second solid-state microbattery component of the plurality of solid-state microbattery components are disposed within the second polymer sealing material of the tape substrate layer.

3. The device of claim 1 , wherein the first solid-state microbattery component of the plurality of solid-state microbattery components is associated with the first polymer sealing material, which is separate from the second polymer sealing material associated with the second solid-state microbattery component of the plurality of solid-state microbattery components.

4. The device of claim 1 , wherein the plurality of solid-state microbattery components are arranged as an array of solid-state microbattery components on the substrate layer.

5. The device of claim 1 , wherein each of the plurality of solid-state microbattery components formed on the substrate layer comprises a respective solid-state electrolyte.

6. The device of claim 1 , wherein the substrate layer and the tape substrate layer facilitates improved quality of the plurality of solid-state microbattery components.
