Li-ion batteries, already widely used in electronics, have specific energies of around 160 Wh/kg and are expected to show more substantial near- and mid-term increases in capacity, rate capability, and stability. Discontinuous improvements in performance are expected to result from the introduction of new materials, including negative electrode materials (especially metals that alloy with Li)

An example of where a modular design would be most appropriate is a sensor net intended to gather audio and/or visual information with 10-100 nodes, some fixed and some moving, with variable assignments that may change during the time of interest. In this case, the power source might be a micro fuel cell or micro heat engine, since audiovisual applications require much energy and a high-bandwidth transmitter.

Most new battery ideas break down in the implementation stages of engineering and manufacturing- areas that are not typically funded by the government. In the case of capacitors, major government development funding was provided by the National Institute of Standards anti Technology (NIST)
