“…The measurement of the supercapacitance performance of the electrode material is performed by cyclic voltammetry (CV) galvanostatic charging-discharging. The electrode material should be fabricated using a material with high specific capacitance and a large number of charge-discharge cycles [8]. For this purpose, bismuth ferrite (BFO) has emerged as a promising material owing to its modifiable redox properties and charge storage capacity [9][10][11][12][13][14][15].…”

BiFe1−xCrxO3, (0 ≤ x ≤ 10) nanoparticles were prepared through the sol–gel technique. The synthesized nanoparticles were characterized using various techniques, viz., X-ray diffraction, high-resolution field emission scanning electron microscopy (HRFESEM), energy dispersive spectroscopy (EDS), UV–Vis absorption spectroscopy, photoluminescence (PL), dc magnetization, near-edge X-ray absorption spectroscopy (NEXAFS) and cyclic voltammetry (CV) measurements, to investigate the structural, morphological, optical, magnetic and electrochemical properties. The structural analysis showed the formation of BiFeO3 with rhombohedral (R3c) as the primary phase and Bi25FeO39 as the secondary phase. The secondary phase percentage was found to reduce with increasing Cr content, along with reductions in crystallite sizes, lattice parameters and enhancement in strain. Nearly spherical shape morphology was observed via HRFESEM with Bi, Fe, Cr and O as the major contributing elements. The bandgap reduced from 1.91 to 1.74 eV with the increase in Cr concentration, and PL spectra revealed emissions in violet, blue and green regions. The investigation of magnetic field (H)-dependent magnetization (M) indicated a significant effect of Cr substitution on the magnetic properties of the nanoparticles. The ferromagnetic character of the samples was found to increase with the increase in the Cr concentration and the increase in the saturation magnetization. The Fe (+3/+4) was dissolved in mixed-valence states, as found through NEXAFS analysis. Electrochemical studies showed that 5%-Cr-doped BFO electrode demonstrated outstanding performance for supercapacitors through a specific capacitance of 421 F g−1 measured with a scan rate of 10 mV s−1. It also demonstrated remarkable cyclic stability through capacitance retention of >78% for 2000 cycles.

“…These binary oxides can offer large capacitance due to involvement of two ions in redox reactions [13,47,50]. Subsequently, several studies were performed on ferrite materials such as nickel ferrite, bismuth ferrite, cobalt ferrite, manganese ferrite, as electrodes in supercapacitor [46,[51][52][53]. Ferrites of the form MFe 2 O 4 (M = Ni, Co, Zn, etc.)…”

Ferrites - Synthesis and Applications

Apart from the magnetic properties, ferrites have been considered as efficient electrodes for next generation energy storage devices. This chapter will include applications of spinel ferrites such as MnFe2O4, CoFe2O4, ZnFe2O4 and NiFe2O4 in supercapacitor. In ferrites, the charge storage arises from the fast-reversible surface redox reactions at the electrode/electrolyte interface. In particular, the electrode material with high specific capacitance, wide range of operating potential, low synthesis cost and its availability on the earth are highly desirable to fabricate a supercapacitor. Ferrites with mixed oxidation states have proved as promising electrodes in supercapacitors. In this chapter, we summarize the different synthesis methods of ferrites based nanocomposites and their electrochemical properties for supercapacitor application.

The synthesis of an organic‐inorganic supramolecular hybrid system has been reported, using a wet‐chemical synthesis method, where the Bi2O3 nanoparticles are dispersed within the organic matrix. The XRD analysis showed the formation of crystalline Bi2O3. The XPS and Raman spectra analysis also confirmed the formation of Bi2O3. In this work, the organic molecule supported nanosized Bi2O3 has been used as an electrode material for supercapacitor application in presence of the aqueous solution of alkaline electrolyte (1.0 mol dm−3 of KOH) and exhibited a specific capacitance 407 F.g−1 along with the energy density value of 113 W.h.kg−1 at 1 A.g−1. The supramolecular system exhibited a long‐term stability by retaining 89% of the initial specific capacitance value after 500 cycles at the current density of 5 A.g−1.
