A Study on Super Capacitor with a Reference of Carbon Nanotubes | Original Article

ABSTRACT:

Supercapacitor finds desirable applications in consumer electronic goods and alternate power sources as an electrical energy storage system due to its higher energy capacity, rapid discharge charge cycle, low heating cost, reliability, long-term operational stability and no removable pieces. This thesis examines the latest supercapacitor advances focused on carbon nanotubes (CNTs) and their composites. The aim is to provide a thorough overview of the advantages and drawbacks of supercapacitor materials associated with carbon nanotubes, and to find ways to increase supercapacitor efficiency. We first explored the impact of pure carbon nanotubes on supercapacity of physical and chemical properties like height, strength, defect, form, functionalization and annealing. The composites, including CNTs oxide and CNTs polymer, were further explored in order to maximize supercapacity and preserve supercapacitor reliability by optimally designing the structure, particle size and distribution.
