A materials research team at Vanderbilt University has designed a new supercapacitor that is made of silicon and has the potential to power many types of devices, from solar cells to mobile devices. The supercapacitor may be made from excess silicon and can provide significant savings in manufacturing costs. The technology cannot store energy the same as lithium-ion batteries, but supercapacitors have promise in consumer devices.
