Abstract: This study aims to compare various combinations of commercially available carbon nanotubes and aqueous electrolytes in terms of their supercapacitor performance to evaluate the best device configuration. The carbon nanotube (CNT) powders were sprayed onto a polymer substrate using an airgun to form a supercapacitor electrode. The device was a 2-electrode configuration of CNT networks, immersed in various liquid electrolytes, which may be a possible area for exploration for flexible power devices in the future. Experimental results have suggested that the combination of one of the commercially available powders, known as P3 single wall nanotube B (P3 SWNT B) and hydrochloric acid form the best device in terms of its performance in energy and power density. The power density calculated was 5404.45 W/kg. Its energy density was also the highest value at 2.33. Further tests have also shown that it has the highest value of specific capacitance at 67 F/g. In this report, the comparison of the properties of the various CNT materials leading to the effectiveness of the device, experimental procedures and calculations involved will be further discussed in the later sections.
