Research Progress of Plant-derived Activated Carbon for Electric Double Layer Capacitors

Electric double layer capacitors (EDLCs) are a type of high-power and long-cycle energy storage device with wide operating temperature range. EDLCs have promising applications in transportation, microgrids, and the internet of things. Activated carbon, which is characterized by its high nanoporosity, high surface area, and high tap density, is the most widely applied electrode material for EDLCs. Plants, owing to the abundance, diversity, and renewability, have been considered as the most promisi...
