Nagaland University Scientists Develop Flexible Supercapacitor for Wearables and Electric Vehicles
In a major scientific breakthrough, researchers from Nagaland University have developed a flexible supercapacitor device capable of powering next-generation wearable electronics, electric vehicles (EVs), and renewable energy systems. The innovation marks a first-of-its-kind study comparing tungsten, vanadium, and cobalt doping in molybdenum diselenide (MoSe₂) for energy storage, going beyond lab-scale research to build a working prototype.
The study, led by Dr. Vijeth H, Assistant Professor, Department of Physics, along with Ms. Pewe-u Marhu, Research Scholar, demonstrates the practical viability of the supercapacitor. The research has been published in RSC Advances, a peer-reviewed journal by the Royal Society of Chemistry.
“This device combines flexibility, high energy storage, and durability, which are critical for future portable and wearable technologies,” said Dr. Vijeth. “Among the materials tested, cobalt proved most effective. The process we used is simple, eco-friendly, and scalable for industrial adoption. This research showcases scientific excellence from the North East and strengthens India’s path toward self-reliant energy solutions.”
Ms. Marhu added that the team’s next steps include optimizing the electrode–electrolyte interface, improving safety using solid-state gel electrolytes, and scaling up the process for pilot-level production in collaboration with industry partners.
The device, developed at the Advanced Materials for Device Applications (AMDA) Research Laboratory at Nagaland University’s Lumami campus, utilizes cobalt-doped molybdenum diselenide (Co@MoSe₂), a cutting-edge two-dimensional (2D) material. It offers an energy density of 34.54 Wh/kg and remains stable across 10,000 charge–discharge cycles, maintaining performance even under repeated bending and twisting.
The project received funding from the Anusandhan National Research Foundation (ANRF), Government of India, with advanced characterization support from the Indian Institute of Science (IISc) Bangalore under its INUP Program.
The innovation is expected to advance India’s clean energy goals under Atmanirbhar Bharat by reducing dependence on imported batteries and enhancing the nation’s renewable energy and electric mobility sectors.
