University of Central Florida researchers have developed a radical new supercapacitor design that could one day replace lithium-ion batteries, allowing users to charge a mobile phone in a few seconds and with a charge that lasts a week, according to the researchers. The new battery would be flexible and a fraction of the size of a lithium-ion battery.

The proof-of-concept design is based on a hybrid supercapacitor composed of a core with millions of highly conductive nanowires coated with shells of two-dimensional materials.* It combines fast charging and discharging (high power density) and high storage capacity (high energy density).
