Batteries are an integral part of our lives and will only become more so as we turn away from fossil fuels. These battery innovations have the potential to change the way we store and use the power.

Microsupercapacitotors are traditionally expensive to make, but students from Rice University have developed a way that dramatically reduces their cost.  By burning electrode patterns into sheets of plastic with lasers, the researchers have developed batteries that can charge faster and discharge slower.
