A multi-institutional research team led by Nagaland University has developed a patented, cost-effective method to produce high-performance electrode material for next-generation energy storage devices. This breakthrough could lead to cheaper and more scalable supercapacitors, researchers said.
These supercapacitors are gaining global interest for their ability to store large amounts of energy and charge rapidly. They can be used as key technology for electric vehicles, renewable energy systems, and grid stabilisation. However, the high cost of electrode materials has been a significant barrier to wider adoption.
The team developed a new approach to produce ‘ functionalized graphene’, a supercapacitor material which is a derivative of reduced graphene oxide. This material can help improve the performance and lower the cost of energy storage systems, researchers said.
Professor Dipak Sinha, Department of Chemistry, Nagaland University, said, “Unlike traditional methods that are time-consuming and resource-intensive, this new approach operates under moderate temperature and pressure conditions. This makes the supercapacitor energy-efficient, faster, and more suitable for large-scale production.
“The process offers a fivefold increase in gravimetric energy density over its non-aminated counterpart while maintaining over 98% energy retention after 10,000 cycles,” Sinha added.
The research was conducted in collaboration with Karnataka universities– Visvesvaraya Technological University and Nagarjuna College of Engineering and Technology. The technology was also granted an Indian patent. “Initial tests show an energy density exceeding 50 Wh/kg and a wide electrochemical window of 2.2v—metrics comparable to global benchmarks,” the university said in a statement.
While the discussions for commercial partnerships are developing, the researchers believe the material’s properties could open avenues for potential applications in electric mobility, defence systems, and critical infrastructure.
