Indian scientists have developed a 3.4V graphene supercapacitor, enhancing energy storage for renewable energy and electric vehicles. This supercapacitor offers higher energy density exceeding 100 Wh/kg, rapid charge-discharge cycles of up to 100,000, and power output at kilowatt levels per kilogram.

The technology integrates with solar power systems for efficient energy storage and can enhance electric vehicle performance as a hybrid module with batteries. The project aligns with India's Atmanirbhar Bharat initiative, supporting the goal of deploying 30 million electric vehicles and achieving 500 GW of renewable capacity by 2030.

Commercial pathways may include partnerships with Tata Advanced Systems and Reliance New Energy. The production method involves scalable chemical vapor deposition for graphene, with potential for cost reduction through government subsidies. Future iterations aim for 4V operation using solid-state electrolytes.
