Lithium-ion batteries of the type used in cell phones, laptops, and gasoline-electric hybrid cars and fuel cell vehicles are very energetic compared to ultracapacitors. Typically, today's commercially available ultracapacitors deliver only one-tenth the energy of a comparable-weight battery, but because they deliver energy much faster than a battery does, they are gaining ground in a market already strongly courted by battery manufacturers.
The announcement of the nanogate capacitor, heralds the imminent arrival of the Leyden jar's descendants into the lithium-ion big league. When nanogate capacitors enter the marketplace they will offer the rapid charge and discharge properties of ultracapacitors along with the energy storage capacity of batteries. This is amazing for a device that is simply an accumulator of electric charge. source: Ultracapacitors Challenge the Battery

Did anyone mention: quantum nanomagnets? Watch for spin batteries
...conversion of the magnetic energy of the superparamagnetic MnAs nanomagnets into electrical energy when these magnets undergo magnetic quantum tunnelling. As a consequence, a huge magnetoresistance of up to 100,000 per cent is observed for certain bias voltages. Our results strongly support the contention that, in magnetic nanostructures, Faraday's law of induction must be generalized to account for forces of purely spin origin. The huge magnetoresistance and e.m.f. may find potential applications in high sensitivity magnetic sensors, as well as in new active devices such as 'spin batteries'. source: Access : Electromotive force and huge magnetoresistance in magnetic tunnel junctions : Nature
