Synthesis and Electrochemical Evaluation of Iron Oxide Nanostructured Electrode Materials for Supercapacitors

Abstract

Supercapacitors are electrical energy storage devices which can deliver large energy in newlinea short time. A supercapacitor can be used as an auxiliary energy device along with a newlineprimary source such as a battery or a fuel cell to achieve power enhancement in short newlinepulse applications. Active materials for supercapacitors are classified into three newlinecategories: (i) carbonaceous materials, (ii) conducting polymers and (iii) metal oxides. newlineAmong the materials studied over the years, metal oxides have been considered as newlineattractive electrode materials for supercapacitors due to the following merits: variable newlineoxidation state, good chemical and electrochemical stability, ease of preparation and newlinehandling. The performance of supercapacitors can be enhanced by moving from bulk newlineto nanostructured materials. newlineThe theme of the thesis is to explore novel routes to synthesize nanostructured metal newlineoxide electrode materials for supercapacitors, and to investigate their physical and newlineelectrochemical characteristics. newlineChapter 1 briefly discusses the importance of electrochemistry in energy storage and newlineconversion, basics of electrochemical power sources, importance of Iron oxides, newlinedifferent synthetic procedures for Iron oxides and its applications newline
