High-performance hybrid supercapacitors

In news

Scientists at the International Advanced Research Center for Powder Metallurgy and New Materials (ARCI), an autonomous body of the Department of Science and Technology, Government of India in collaboration with IIT Hyderabad have developed high-performance hybrid supercapacitors.

Highlights
  • It is low-cost supercapacitor device with excellent capacitive retention.
  • It can pave the way for the next generation high power-high energy storage devices.
  • Hybrid supercapacitors combine the features of both conventional double layer supercapacitors and batteries and act as high power-high energy storage devices. 
Supercapacitor Properties
  • These hybrid supercapacitor have high power density, long cycle life, and excellent capacity retention compared to their battery counterparts.
  • These electrodes have excellent electrochemical performance.
  • It contains nanosheet structures with incorporated oxygen vacancies as an active material, for hybrid supercapacitors.
Supercapacitors 

These are electrochemical energy storage devices that store and release energy by reversible adsorption and desorption of ions at the interfaces between electrode materials and electrolytes.
