π Supercapacitors
π Whatβs the News?
β Indian researchers have developed a high-voltage supercapacitor using a dual-functional porous graphene carbon nanocomposite (PGCN) electrode.
β The innovation can significantly boost electric vehicle (EV) performance and renewable energy storage.
π Why is it Important?
β Faster acceleration and extended driving range for EVs
β Improved solar and grid-scale energy storage efficiency
β Supports clean energy transition
π About Supercapacitors
β Electrochemical devices that store charge via electrostatic action (not chemical reactions like batteries)
β Key components: Anode, Cathode, Electrolyte, Separator
β Use high specific surface area electrodes and thin dielectrics β very high capacitance
π Key Advantages
β Long cycle life (millions of chargeβdischarge cycles)
β High power density (rapid charging & discharging)
β Environment-friendly and durable
π UPSC Relevance
β GS3 β Science & Technology | Energy Storage | EVs | Climate Tech
π Prelims Pointer:
β‘οΈ Supercapacitors β Batteries β High power delivery but lower energy density than batteries.
