Just as embedded electronics are becoming an integral part of sensors, unmanned aerial vehicles, and a number of other instruments, so are embedded power sources. In a larger-scale application such as power generation, existing silicon-based and futuristic high-efficiency thin-film solar cells will have high-energy-density and high-powerdensity thin-film batteries for energy harvesting, storage, and delivery. This article describes some of the recent developments at APL in the area of three classes of emerging battery technologies. In one class, the batteries are embedded into the instrument by fabricating them in conformal shapes. In the second class, the objective is to grow them on surfaces that serve as the skin of the solar cell or the skeleton of the instrument. In the third approach, using emerging nanotechnology, battery chemicals are encapsulated inside metal nanotubes that are grown in situ in thin-film polymer sheets that are subsequently bonded together into batteries.
