In embodiments, a solid-state electrolyte layer, which may be a consolidated structural layer, offers many performance advantages. For example, the structural integrity conferred by a solid electrolyte combined with solid electrodes may eliminate the need for an external case, in some embodiments. For example, in one embodiment, the energy storage device can be naked, i.e., not associated with any other structural materials. In some embodiments, the energy storage device may be built up as an integral circuit element within a larger microcircuit with wafer fabrication techniques. These examples may not possible with conventional battery technologies. The solid-state energy storage devices described herein also may possess inherent physical robustness and a high immunity to shock, vibration, and temperature extremes. In addition, the solid-state energy storage devices described herein are highly scalable such that they may be closely coupled to such entities as MEMS devices and microfluidic systems.
In exemplary embodiments, a solid-state energy storage device becomes, in essence, another circuit element in an integrated circuit and facilitates the realization of optimal circuit paths and grounding schemes because it lends itself to strategic placement within the overall circuit. In some embodiments, this can eliminate as much as 70% of the circuitry (e.g., the portion served by power pins) in existing VLSI/ULSI chips, greatly reducing size and heat generation.
