Researchers develop new material to bring down cost for next-gen energy storage systems
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. #Pahalgam Terrorist Attack India orders nationwide defence drills as Indo-Pak tensions rise From blackouts to bunkers: Inside India's civil defence mock drills across 244 districts on May 7 A woman spy who helped India defeat Pakistan in 1971 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. EV calculator How much will I save if I choose an electric vehicle?

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 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.

Nagaland varsity team develops aminated graphene technique
1 2 Guwahati: A research team led by Nagaland University developed an innovative and economical technique for creating an advanced material used in ' supercapacitors ', which are next-generation energy storage devices . These devices are notable for their quick charging capabilities and substantial energy storage capacity, unlike conventional batteries. They are considered a viable solution for meeting increasing demands for efficient and sustainable energy systems. However, the high costs of electrode materials have limited their widespread adoption, despite being crucial for performance. The research aligns with India's emphasis on environmentally conscious technologies and clean energy. The team developed a novel approach to produce aminated graphene from reduced graphene oxide. This method is cost-efficient and faster than conventional processes, with the resulting material showing favourable electrochemical properties. The research secured an Indian patent and is ready for potential commercial application. The collaborative effort involved researchers from Nagaland University, Visvesvaraya Technological University, Karnataka, and Nagarjuna College of Engineering and Technology, Karnataka. The team comprised Suraj Kumar, Prof Dipak Sinha, Prof Dinesh Rangappa, Priyakshi Bora, Kunal Roy and Navya Rani M. Their findings appeared in iScience, an open-access Cell Press journal covering various scientific disciplines.

Nagaland University-led research team develops cost-effective material for use in next generation energy storage devices
The Nagaland University-led multi-institute research team has developed a cost-effective method to create an advanced material for building next-generation energy storage devices called 'Supercapacitors'. They are gaining attention due to their ability to store large amounts of energy and charge very quickly, unlike traditional batteries. These devices are widely seen as a potential solution to the growing demand for more efficient and sustainable energy systems. A critical part of a supercapacitor's performance is the material used for its electrodes. The high cost of these materials has been a barrier to widespread use. Suraj Kumar, DST-INSPIRE Fellow, Nagaland University said, 'The material itself is not indigenous; however, the process developed for its synthesis can be considered indigenous. While supercapacitors differ significantly from batteries in their operation and characteristics, the energy density of our tested supercapacitor is comparable to that of Nickel-Cadmium (Ni-Cd) batteries'. This research aligns closely with India's growing focus on clean energy and environmentally responsible technologies. In this context, the team developed a new approach to produce aminated graphene, a derivative of reduced graphene oxide. This method is notably cost-effective, faster, completing the entire procedure much more quickly than the traditional processes. Further, the obtained material also demonstrated good electrochemical properties. This kind of material can help improve the performance and lower the cost of energy storage systems. Initial lab tests have shown promising results. The research has already received an Indian patent. The research is now at a point where it can be taken further for possible commercial use. The team This research was taken up by a team comprising researchers from Nagaland University, Visvesvaraya Technological University, Karnataka, and Nagarjuna College of Engineering and Technology, Karnataka. They have developed a cost-effective method to produce high-performance 'functionalised graphene' supercapacitor material. It features a wide electrochemical window, good stability, and an impressive energy density. The study was conducted by Mr. Suraj Kumar, a DST-INSPIRE Fellow, Nagaland University working under the joint supervision of Prof. Dipak Sinha, Chemistry Department, Nagaland University and Prof. Dinesh Rangappa from Visvesvaraya Technological University, Karnataka. The team also included Ms. Priyakshi Bora from Nagaland University, Mr. Kunal Roy from Visvesvaraya Technological University and Dr. Navya Rani M. from Nagarjuna College of Engineering and Technology. The findings were published in iScience, an open-access journal from Cell Press that provides a platform for original research in the life, physical, social, earth, social, and health sciences. Elaborating on this research, Prof. 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, making it energy-efficient, faster, and more suitable for large-scale production.' Prof. Dipak Sinha added, 'The resulting material not only simplifies the manufacturing process but also delivers significantly enhanced performance, enabling a supercapacitor with a wide 2.2 V electrochemical window, an energy density exceeding 50 Wh/kg, and 98% energy retention after 10,000 cycles. Notably, it achieves a fivefold increase in gravimetric energy density compared to its non-aminated counterpart, demonstrating both scientific novelty and commercial potential.' Elaborating further on the advantages of this new method, Mr. Kumar added, 'Traditional methods demand high temperatures, elevated pressures, and lengthy processing times, which add to the complexity and cost of production. Conventional methods typically involve converting bulk graphite into graphene oxide, followed by a series of steps to reduce and functionalize it. The developed process in contrast, is a one-pot synthesis that directly transforms bulk graphite into aminated graphene. This process not only reduces time and resource usage but also operates under moderate temperature and pressure, making it scalable and energy-efficient. Notably, it stands out as one of the quickest methods available for producing this material.'
