In a major stride toward sustainable energy and technological self-reliance, a research team from Nagaland University has developed an innovative supercapacitor material that could revolutionize the future of energy storage. This groundbreaking invention is faster, longer-lasting, and far more cost-effective than current lithium-ion batteries, offering tremendous potential across industries—from electric vehicles to renewable power grids.
At the core of this breakthrough lies a novel, single-step process to create aminated graphene from common graphite. This material dramatically enhances the performance of supercapacitors—devices that store and release energy rapidly—making them highly viable for real-world applications.
Unlike traditional supercapacitors that rely on rare-earth materials and energy-intensive manufacturing, the method developed by the Nagaland team operates under ambient conditions, reducing cost and environmental impact while delivering superior electrochemical performance.
Exceptional Performance Metrics
The new supercapacitor material boasts:
Charging speeds exponentially faster than lithium-ion batteries
2.2V electrochemical window—an industry-leading figure
Energy density exceeding 50 Wh/kg, nearly 5x higher than comparable materials
98% capacity retention after 10,000 full charge-discharge cycles
These numbers place the innovation far ahead of existing supercapacitor technologies and make it ideal for heavy-use scenarios, such as:
Electric vehicles (EVs) needing quick recharging
Regenerative braking systems in metros and buses
Telecom backup systems and grid-scale renewable energy storage
‘Make in India’ Meets Green Energy
This invention isn’t just about energy—it’s about energy independence. By eliminating reliance on imported battery components, the technology fits squarely within the ‘Make in India’ and ‘Aatmanirbhar Bharat’ vision.
The research team has already secured an Indian patent, and international patents are underway. This recognition speaks volumes about the global significance of their work. The breakthrough also aligns with India’s ambitious climate goals and transition to clean energy by 2030.
Professor Deepak Sinha, one of the lead scientists, emphasized the simplicity and power of the new process:
“Our method eliminates the need for complex multi-stage fabrication and high energy input. We’re delivering top-tier energy storage performance using a straightforward, scalable process.”
Collaborative Excellence
This discovery is a result of cross-institutional collaboration involving:
Nagaland University
Visvesvaraya Technological University
Nagarjuna College of Engineering and Technology
The findings have already been published in iScience, a renowned international scientific journal, further validating the innovation on a global platform.
A Future-Ready Technology
With its exceptional cycle life, affordable production, and rapid energy delivery, this technology has the potential to:
Lower EV costs
Boost domestic battery manufacturing
Enable India to leapfrog global leaders in energy storage
Industry analysts are already calling this a “potential cornerstone” of India’s clean energy future, and a green signal for global players looking for sustainable, cost-effective energy solutions.
As the world shifts to renewable energy and smarter grids, Nagaland’s scientific leap could well become a beacon for innovation and sustainability—positioning India at the forefront of the global clean energy race.
