Abstract
The efficient storage of electrical energy produced from renewable sources of energy is a crucial challenge and has attracted immense interests of the researchers. Electrochemical storage of the energy is proved to be an efficient and effective solution that suggests battery, supercapacitors and fuel cells. The lithium-ion battery is one of the most prominent existing solutions in the energy storage market which is being used in the technology devices. A supercapacitor is another alternative that evinces the potential to emulate battery technology in the upcoming years. To achieve this decisive task, electrode materials having high energy density and electrochemical stability are needed to be explored that should be environment-friendly and economical to be used. Carbonaceous materials, metal oxides, polymers, and their composites are being used for this purpose having a particle size in the nano range. Nanomaterials are proved to be an active candidate due to high surface area and a large number of active sites. Here, we synthesized and investigated bismuth nanomaterials that showed quite high energy density, power density and stability and can be used as electrode materials for supercapacitor applications. The thesis mainly focusses on bismuth-based materials, their synthesis and more concerned about the study of supercapacitive applications via electrochemical techniques. A facile synthesis method of nanoparticles at ambient conditions stabilized by organic matrix has been presented in this report...
