Maybe these will be the batteries we have been looking for 
If this works out well we can power things like bugbots cheaply.

Perhaps this will be a better way to go than carbon nanotube super capacitors which are similar to LioN batteries in storage capacity.
This may soon be a DARPA project.

The concept calls for billions of nanoscale capacitors and would rely on quantum effects--the weird phenomena that occur at atomic size scales--to boost energy storage. Conventional capacitors consist of one pair of macroscale conducting plates, or electrodes, separated by an insulating material. Applying a voltage creates an electric field in the insulating material, storing energy. But all such devices can only hold so much charge, beyond which arcing occurs between the electrodes, wasting the stored power.
If capacitors were instead built as nanoscale arrays--crucially, with electrodes spaced at about 10 nanometers (or 100 atoms) apart--quantum effects ought to suppress such arcing.
