Nanotechnology for Energy - Portable Power

Portable devices are commonplace in modern society, from consumer products such as mobile phones and MP3 players, to medical diagnostic equipment, to environmental and chemical sensor equipment. In all cases increased functionality, smaller size and longer operating times are desired. This can include improvements to existing systems such as rechargeable batteries to supply more power and energy. It can also include new technologies such as fuel cells which generate electricity from hydrogen (see separate section).

Increases in the energy and power output of portable supplies can not only affect portable devices, but at the other end of the scale could offer breakthroughs for all-electric vehicles, for off-grid power systems and for high-technology applications such as aeronautics. The global battery market is worth some 30 billion USD and is increasing dramatically.
