Indian researchers created a flexible, durable supercapacitor with high energy density, boosting applications in wearables and electric vehicles.

Researchers at Nagaland University, backed by the Indian Institute of Science and the Anusandhan National Research Foundation, have developed a flexible supercapacitor using cobalt-doped molybdenum diselenide that achieves an energy density of 34.54 W h kg⁻¹. The device maintains performance over 10,000 charge-discharge cycles and withstands bending and twisting, making it suitable for wearables, electric vehicles, and renewable energy systems. Published in RSC Advances, the study found cobalt doping most effective among tested elements. The innovation supports India’s Atmanirbhar Bharat initiative by reducing dependence on imported batteries. Next steps include optimizing the electrode-electrolyte interface, adopting safer solid-state electrolytes, and scaling production, with industry partnerships under consideration.
