“…The band appeared at 508 cm −1 is due to the out-of-phase stretching vibrations (B 1 g mode) of the BO 6 octahedra, which is closely associated with John-Teller distortion. 32 Observation of bands at 1473 and 1565 cm −1 are the respective characteristic D and G bands of rGO in the composite. The appearance of G band is common for all sp 2 carbons in graphite (1597 cm −1 ), GO (1607 cm −1 ), and rGO (1595 cm −1 ) due to C C stretching vibrations.…”

Lanthanum ferrite decorated reduced graphene oxide (LaFeO3/rGO) nanocomposite is prepared by in-situ microwave irradiation method. The X-ray diffraction study reveals the single phase orthorhombic structure of LaFeO 3 nanoparticles and LaFeO 3 /rGO nanocomposites. The FTIR study reveals various vibrational modes and the characteristic D and G bands of the Raman spectrum confirms the formation of reduced graphene oxide. The SEM and HR-TEM images demonstrate that spherical LaFeO 3 particles are decorated on 2D graphene sheets. From the HR-TEM study, the average particle size of LaFeO 3 is estimated to be 23 nm. The synergistic effect of 3D LaFeO 3 nanoparticles and 2D graphene layers offers more active sites to achieve the enhanced electrochemical performance. The specific capacitance of LaFeO 3 / rGO composites is measured to be 170 Fg −1 at 10 mV s −1. The composite electrode has admirable cyclic stability, better Columbic efficiency and improved capacitance retention with great potential for supercapacitor applications.

Advanced materials and technologies for supercapacitors used in energy conversion and storage: a review

Supercapacitors are increasingly used for energy conversion and storage systems in sustainable nanotechnologies. Graphite is a conventional electrode utilized in Li-ion-based batteries, yet its specific capacitance of 372 mA h g −1 is not adequate for supercapacitor applications. Interest in supercapacitors is due to their high-energy capacity, storage for a shorter period and longer lifetime. This review compares the following materials used to fabricate supercapacitors: spinel ferrites, e.g., MFe 2 O 4 , MMoO 4 and MCo 2 O 4 where M denotes a transition metal ion; perovskite oxides; transition metals sulfides; carbon materials; and conducting polymers. The application window of perovskite can be controlled by cations in sublattice sites. Cations increase the specific capacitance because cations possess large orbital valence electrons which grow the oxygen vacancies. Electrodes made of transition metal sulfides, e.g., ZnCo 2 S 4 , display a high specific capacitance of 1269 F g −1 , which is four times higher than those of transition metals oxides, e.g., Zn-Co ferrite, of 296 F g −1. This is explained by the low charge-transfer resistance and the high ion diffusion rate of transition metals sulfides. Composites made of magnetic oxides or transition metal sulfides with conducting polymers or carbon materials have the highest capacitance activity and cyclic stability. This is attributed to oxygen and sulfur active sites which foster electrolyte penetration during cycling, and, in turn, create new active sites.

“…Ca 2.9 Nd 0.1 Co 4 O 9+δ perovskite has demonstrated good performance in electric double-layer capacitors, which provided a capacitance value of 53.6 F g −1 and an energy-density value of 16.7 Wh kg −1 , with high electrode cyclic stability of charge–discharge [ 59 ]. Furthermore, La 0.8 Nd 0.2 Fe 0.8 Mn 0.2 O 3 -based, nitrogen-doped graphene oxide (LNFM/NGO) composites have been synthesized by the hydrothermal method, and typically the composite reveals good electronic conductivity, maximum specific capacitance (1060 F g −1 @ 50 mV s −1 ), and outstanding capacitive retention stability (specific capacity retention of 92.4% after 10,000 cycles) [ 60 ]. Interestingly, the active nickel-stannate-supported graphene nanosheet (NiSnO 3 /GNS) composite acts with a conducting nature for fast ion transportation during the electrochemical process, which significantly improved their specific capacitance behavior (891 F g −1 @ 5 mV s −1 ), with excellent cyclic charge–discharge stability (88.3% capacitance retention after 4000 cycles) [ 61 ].…”
