Abstract:
Suggested beneficial effects of surfactants added to the electrolyte solution of supercapacitors have been studied with the aim of improving wetting of the metal oxide electrode surface possibly enhancing material utilization and overall performance. Using representative non-ionic and anionic surfactants such improvements in terms of increased specific capacitance, capacitance retention with current density and improved stability were found. Further examination of type of surfactant and optimum surfactant concentration are recommended.
