Electrochemical Supercapacitors of Anodized Nanostructues

Abstract

The energy is considered as one of the greatest beneficial things for mankind in last year s. There are many types of resources power generation for both the depleted and renewable. Fossil fuels are nonrenewable resources that need for create it millions of years. Moreover, fossil fuels are depleted very fast and environment pollution compare to other resources such as sun, wind and so on. Consequently, the continues to use fossil fuels lead to increase the CO2 in atmosphere this in turn to be the main factor in generate global warming phenomena. The energy renewable is one of the solutions to this energy challenge for reducing negative effects from fossil fuels. The scientist are focusing on the development conversion and storage energy systems to useful from the alternative and renewable energy sources such as batteries, fuel cells, and supercapacitors, etc. Due to the high power density of supercapacitor that gives it priority as the best storage energy system. The nano-size electrode play crucial role in store energy which is considered the hurt of supercapacitor system. Beside the size of nanostructures also the types of nanomaterials which gives superb properties in storage energy such as carbon, graphite, transition metal oxides, and conducting polymers. The morphology of electrode materials is important to obtain the great capable in supercapacitor performance. newlineIn this dissertation, the anodization method is one of the brilliant methods to tailored and provide the surface of substrate by nanoscale. Different nanostructures are occurred relied upon the nature of metal used. On other hand, there are various parameters that can assist to gain different nanostructure on same substrate such as time, voltage, concentration and type of electrolytes. The advantages of the anodization method are cost-effective, stability, and excellent adhesion and so on., newlineIn this work, firstly we anodized the brass (Cu-Zn) foil in acidic media by using anodization method. The structural elucidation demonstrat
