Executive Summary : | supercapacitors are energy storage devices that offer instant power delivery and can sustain millions of charge-discharge cycles at higher current densities. The performance of supercapacitors is governed by the porosity and surface area of active materials, which can only be achieved using nanostructured materials with high surface-to-volume ratios. Metal pyrophosphates exhibit exceptional properties like enhanced electronic conductivity, increased availability of redox active sites, and rich mixed valences of metals. Porous one-dimensional nanostructures in the form of nanofibers accelerate electrochemical reactions and provide a large surface area for electrode-electrolyte interaction. Electrospun nanofibers possess exceptional surface area-to-volume ratio, tunable porosity, and superior mechanical properties, making them a desirable choice for supercapacitor applications. This project aims to develop asymmetric supercapacitors using transition metal pyrophosphate (TMP) as active electrode material and Canbon nanofibers (C NFs) as active material for the second electrode. The fabrication process involves cost-effective methodology and optimization of process parameters. The fabricated TMP NFs & C NFs asymmetric supercapacitors will be tested using constant current charge-discharge technique and cyclic voltametric & electrochemical impedance spectroscopic technique using an Electrochemical Work station (EWs). |
