New battery materials

Other researchers from the University of Maryland have also been working to improve the capacity of lithium-ion batteries. Last year it was reported that a biological virus known as the Tobacco mosaic virus (TMV) could increase the surface area of electrodes in a battery, resulting in a ten-fold increase in energy capacity.
Meanwhile in September scientists at the University of Leeds invented a jelly lithium battery. The flexible polymer gel batteries can be shaped and bent to fit virtually any device and can be made just nanometres thick at a rate of ten metres per minute.

absolutely awesome
 
From the /. story
Adds a story at ExtremeTech, "The only problem is, a high-voltage cathode (-) requires a very low-voltage anode (+) — and the Stanford researchers haven’t found the right one yet; and so they haven’t actually made a battery with this new discovery."
