“…They utilized a one-step methodology for the synthesis of the binary composite while a two-step approach was developed for ternary composite (RGO/CoFe2O4) with urea. The heterostructures offered synergistic interactions and thus offered high energy and power density with excellent specific capacitance [21]. Amani et al conducted another study in which they used an MnCoFeO4 based electrode for supercapacitor applications.…”

Supercapacitors have emerged as efficient energy storage devices for future autonomous gadgets due to their exorbitant power density, quick charging/discharging abilities, with prolonged cycle life. However, to meet demands such as high energy density and superior electrochemical performance, it is imperative to investigate different electrode materials. Primarily, electrode materials with a catholic potential range, low cost, and high specific capacitance are highly sought-after for supercapacitor applications. The cobalt ferrites (CoFe2O4) have emerged as materials with extraordinary specific capacitance, admirable redox response, are cost-effective, and are also environmentally friendly. In the present review article, we have discussed past reports where cobalt ferrites have been explored as potential candidates for supercapacitor applications.

Energy demand has become a persistent concern and high‐performance energy storage systems have increasingly undergone development. Supercapacitors and batteries pose great impact on energy storage and garner a great deal of attention from technologies and researchers alike. The performance of energy saving devices is primarily determined by the electrode material in terms of high specific capacitance, excellent conductivity, remarkable natural abundance, and unique electrochemical qualities, also large surface area. Cobalt (Co)‐based materials are unique electrode materials widely used in energy storage devices. Nevertheless, a combination of Co and ferrite materials such as nickel, zinc, and copper, or Co/nonferrite materials like metal–organic frameworks and layered double hydroxides has improved their ultimate efficiency. This review deals with energy storage applications of Co‐based materials, categorizing ferrites, their electrochemical characterization, performance, also design and manufacturing intended to supercapacitors and batteries applications. Summarizing the main outcomes of the literature on batteries and supercapacitors, energy storage systems comprising Co‐based materials combined with carbon nanotubes, graphene, silica, copper, zinc, nickel, cadmium, ferrous, and lanthanum are reviewed and discussed. Lithium‐ion batteries are investigated specifically, and perspectives on Co‐based ferrite development for future generations of supercapacitors and batteries are outlined.

Physicochemical properties emerging nanomaterials possessing tungsten (W) are unique and the applications could be extended over a wide spectrum as nanocomposite electrodes for effective high voltage energy storage applications. Herewith, W doped spinel ferrite nanostructures was synthesized with facile hydrothermal strategy to get MnCo1.98W0.02O4 (MnCoW). The spectroscopic characterization studies proved spherical subunits embedded onto nanosheets formed by W doped bimetallic oxide with a crystalline phase. The resistance due to charge transfer of the electrodes was reduced which led to enhanced transfer of charge across interface of electrode and electrolyte was addressed upon W doping. Carbon based nanocomposite electrodes endowed by their unique structures and the electrochemical performance with various aqueous electrolytes were tested in an asymmetric supercapacitor application. Excellent capacitance development from 141.2 F g−1 to 203.7 F g−1 was achieved by W doping possessing an energy density of 17.9 Wh kg−1. A superior capacitance retention of 91 % was obtained from MnCoW‐based device right after 10000 cycles (charging/discharging) at 1 A g−1. The designed supercapacitor device employing MnCoW electrode exhibited better lifetime performance during lighting a LED under various angles.
