Researchers from various institutions under Nagaland University achieved an energy storage breakthrough through their patented low-cost method of producing superior supercapacitor electrode material for next-generation applications. Super capacitors are becoming more popular worldwide because they offer quick charge times along with high storage capacity.
Electrode materials currently present the main obstacle against scaling up supercapacitor deployment. The researchers developed a new approach using functionalized graphene which handles the efficiency and cost challenges through materials derived from reduced graphene oxide.
This research partnership between Visvesvaraya Technological University and Nagarjuna College of Engineering and Technology resulted in an innovative patented solution that earned credit through Indian patent approval.
Professor Dipak Sinha from Nagaland University's Department of Chemistry, who led the effort, explained, “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.”
According to the university, initial tests showed an energy density of over 50 Wh/kg and an electrochemical window of 2.2V, figures that match international standards. With commercial discussions underway, the innovation is set to unlock opportunities in electric vehicles, defence systems, and critical infrastructure.
