New Paper-Thin, Quick-Charging Supercapacitor

Researchers from UCLA’s California NanoSystems Institute (CNSI) have developed a new generation of supercapacitors that not only emphasizes the best inherent properties of the supercapacitor itself, but also combines it with some of the best qualities of batteries to make a new energy storage medium.
The new supercapacitor is paper-thin and has an extremely fast recharge time. Additionally, it can last more than 10,000 recharge cycles.

“The microsupercapacitor is a new evolving configuration, a very small rechargeable power source with a much higher capacity than previous lithium thin-film microbatteries,” said Maher El-Kady, co-author of the study and postdoctoral scholar.
This from UCLA:
The new components combine laser-scribed graphene, or LSG — a material that can hold an electrical charge, is very conductive, and charges and recharges very quickly — with manganese dioxide, which is currently used in alkaline batteries because it holds a lot of charge and is cheap and plentiful. They can be fabricated without the need for extreme temperatures or the expensive “dry rooms” required to produce today’s
