Symmetrical Supercapacitor with Asymmetric Electrode Construction

Energy storage technology has become an enabling technology for renewable energy applications and enhancing power quality in the transmission and distribution power systems. Energy storage systems provide a wide array of technological approaches to managing our power supply to create a more resilient energy infrastructure and bring cost savings to utilities and consumers. Double-layer capacitors, also referred to as symmetrical supercapacitors, have two electrodes that are identical and made of the same substance, usually a combination of activated carbon and a suitable transition metal oxide. Due to their low internal resistance and linear charge/discharge characteristics, they excel in high-current bursts. They might not have as much energy density as batteries / asymmetrical supercapacitors, but they are better suited for tasks like reducing peak current demand from the main energy source or absorbing power fluctuations. However, further research is needed to improve their energy density and reduce costs for widespread commercial use. Lot of research work is found with respect to material and construction of symmetrical and asymmetric supercapacitors. This study investigates the effects of using fork-shaped electrodes in symmetrical supercapacitors, where both the electrodes adopt this unique design.
