Ferrite and Molybdate‐Based Nanostructured Materials for Supercapacitor Applications

Despite the high theoretical capacitance of the ferrites and molybdate-based supercapacitor, the limited energy density and low cyclability of these supercapacitors seriously hinder their practical applications. Recently, many new strategies have been implemented to solve the aforementioned problem. The use of nanostructured ferrites and molybdate-based material as electrodes in supercapacitors will enhance the faradaic reactions via introducing elevated surface area and uniform porosity in solid as well as liquid electrolytes. The use of carbon-based materials (carbon nanotube [CNT], multi-walled carbon nanotube [MWCNT], single-walled carbon nanotube [SWCNT], etc.), graphene, polymer, etc. enhances the supercapacitive performance of the ferrites and molybdate-based supercapacitors. In the present review, we briefly discussed many advanced strategies to increase energy density and cycliability of ferrites and molybdate-based supercapacitors. Also, in this chapter, we discussed the recent finding on ferrites and molybdate-based supercapacitors as capable alternative high-energy storage devices for energy applications.
