Researchers have created energy storage device at UCLA's California NanoSystems Institute by joining two nanomaterials.They combines the best qualities of batteries and supercapacitors.The resaerchers used supercapacitors unlike batteries because they are electrochemical components which can charge in seconds and can be used for 1 million recharge cycles.
This hybrid supercapacitor has enough capacity to store large amount of energy as well as quickly recharges.The scientists from CNSI created very small capacitor to fit in wearable devices that is known as "microsupercapacitor".Microsupercapacitor's thickness is 1/50th of a paper sheet and has potential to store more than twice charge.
The study was published in the Proceedings of the National Academy of Sciences, and led by Richard Kaner, who is a professor of chemistry and biochemistry and materials science and engineering, and Maher El-Kady, a postdoctoral scholar.
El-Kady said that the microsupercapacitor is a new evolving configuration, a very small rechargeable power source with a much higher capacity than previous lithium thin-film microbatteries.
The scientists used combination of two new laser scribed graphene or LSG components with manganese dioxide that are very conductive and charges and recharges in short time.Manganese dioxide is inexpensive and able to holds more charge which is used in alkaline batteries.
Kaner said that the microsupercapacitor is very thin you could out it inside the adhesive bandage to supply the current.You could also recharge it quickly and use it for a very long time.
"The LSG–manganese-dioxide capacitors can store as much electrical charge as a lead acid battery, yet can be recharged in seconds, and they store about six times the capacity of state-of-the-art commercially available supercapacitors," Kaner said. "This scalable approach for fabricating compact, reliable, energy-dense supercapacitors shows a great deal of promise in real-world applications, and we're very excited about the possibilities for greatly improving personal electronics technology in the near future."
