In the domain of electrochemical storage systems; Supercapacitor is such a potential candidature, which can furnish excellent specific power density, enabling faster charging/ discharging rates, prolonged cycle life, and substantial temperature tolerance (down to -40 °C) compared to batteries. One of the most fascinating recent applications of supercapacitors has been found in the emergency doors of the Airbus A380. This example supports the reliable and safe application of a new age supercapacitors. The major pitfall in the arena of ultracapacitor is its comparatively lower energy density  than commercial batteries. This fact has paved the path for an ampler research in the field of supercapacitor, where the cardinal objective of the research group is to boost their energy density while retaining their high power capability. The selection of suitable materials and their optimized design for electrodes are the key strategies to make supercapacitors more potent energy storage devices than batteries. Our research group is focusing on both type of supercapacitors - electric double layer capacitors (EDLC) and pseudocapacitors as well as supercapattery. The prime concern is mainly on the synthesis of high surface area, porous and conductive electrode materials to enhance the energy density while retaining the power density. Moreover, our research also covers design of novel electrolytes with higher ionic conductivity to improve charge storage and fine-tuning of the interplay of the distinct components of supercapacitors to achieve higher electrochemical performance.
