High Rate Pseudocapacitive Energy Storage in Transition Metal Oxide (TMO) Electrodes for Aqueous Supercapacitors

With global energy consumption constantly on the rise, alternative energy storage solutions are in high demand. The electrification of the transportation industry and the continued push for green energy has spurred the automotive and transportation market to seek improved energy storage elements that combine both high energy and power – and are available in a smaller size and at a lower cost. TMOs exhibit various oxidation states, and the charge transfer between them can be exploited in reversible redox reactions. This faradaic charge storage mechanism, so called pseudo-capacitance leads, in combination with the conventional double layer charging, to an increased chare storage capacity of the device. Also, the kinetics for electrolyte decomposition depend strongly on the electrode material, and it has already been demonstrated that metal oxides have the potential to increase the available electrochemical window in SC leading to an increased operating voltage and higher power and energy densities. In this talk an overview on the advantages and innovation of our high rate aqueous pseudo-capacitor will be outlined, with specific emphasis on the design and development of novel TMO composite materials for enhanced and reliable performance.
