Fabrication and characterisation of fabric based supercapacitors

This dataset is for the paper that presents details of the design, fabrication and characterisation of fabric supercapacitor devices. The proposed fabric supercapacitor devices were based on textile electrodes fabricated by a dipping technique. The textile electrodes were made with low cost porous activated carbon powder, polymer binder and polyester-cotton fabric substrates. Before supercapacitor cell assembly, some of the textile electrodes were also used to evaluate a vacuum impregnation process. The performance of the fabric supercapacitors with different percentages of carbon materials were characterised by cyclic voltammetry, galvanostatic cycling and electrochemical impedance spectroscopy. The sandwich structured supercapacitor devices achieved a high capacitance per cost of 82.9 F.$-1, mass specific capacitances of 14.1 F.g-1, area specific capacitance 0.114 F.cm-2 and maintained 99% of the initial capacitance after cycling more than 15000 times.
