A new technology promises to radically expand energy storage potential in the home or office by transforming structural materials such as walls and device casings into super capacitor batteries.

Engineers from Vanderbuilt University have developed a new form of super capacitor which is capable of serving as both an energy storage medium and a structural building material. Electricity can be stored directly in the structural super capacitor material, which is also sturdy and resilient enough to be employed as the casing of a smart phone, the chassis for…
