Nano-materials seem to be one of the keys to improving the capability of batteries to absorb, store and discharge energy. AltairNano and A123 systems are both using the tiny particles in the construction of electrodes for their batteries.

Another newcomer is now following the same path. Nanoexa has a subsidiary in South Korea called Decktron that is making lithium ion batteries. The company is claiming that Nanoexa's new nanocrystalline material that is being used to construct the positive battery electrodes allows them to achieve an energy density of 3kW/kg. If Decktron can achieve this level of energy density and match some of the longevity claims of AltairNano it could be a real breakthrough.
