“Supercapacitors” have attracted a lot of attention because of their excellent power density and extended cycling life. They are regarded as the promising next-generation energy storage devices to replace traditional batteries. Based on their charge storage mechanism, supercapicitors can be divided into two categories: electrical double-layer capacitors (EDLCs), which store charge via the electrical double-layer at the electrode/electrolyte interface, and pseudocapacitors which depend on the reversible faradic reactions to store charge. The research paper explores new ternary transition metal oxides systems, finding ways to modify existing systems (e.g. improving electrical conductivity, enhancing their cycling stability and increasing the energy density even further).
