Metal Oxide-based Supercapacitors: Progress and Prospective

Abstract

Distinguished by particular physical and chemical properties, metal oxide materials have been the focus of research and exploitation for energy storage. Used as supercapacitor electrode materials, metal oxides have certified attractive performances for fabricating various supercapacitor devices in a broad voltage window. In comparison with single metal oxides, bimetallic oxides materials are highly eager for putting the constraint about the poor electric conductivity away, achieving high capacitances, and bringing the energy density to a new height at this capacitor-level power. Herein, we expound the principal elements affecting the properties of bimetallic oxides electrodes to reveal relevant energy storage mechanisms. Thus, the influences of the chemical constitution, structural features, electro-conductivity, oxygen vacancies and various electrolytes in electrochemical behaviors have been included. Moreover, the progress, development and improvement of multifarious devices have been emphasized systematically from asymmetric to hybrid configuration, containing aqueous and non-aqueous systems. Ultimately, some obstinate and unsettled issues are summarized as well as prospective direction on metal oxide-based supercapacitors.
