“…Solar energy, wind energy, tidal energy, etc., as valuable energy provided by nature to humans, are kinds of intermittent energy. To address this problem, energy storage devices have also been developed, such as lithium-ion batteries, sodium-ion batteries, aluminum-ion batteries, and supercapacitors (Kundu et al, 2015;Sun et al, 2015;Nayak et al, 2017;Ho and Lin, 2019). With the continuous development of science and technology, the requirements of 3C (Computers, Communication, and Consumer electronics) products for batteries are gradually increasing.…”

Bismuth ferrite (BFO) is considered as a significant (ABO 3) perovskite ceramic in electronics and energy storage. Since the A site (Bi 3+) presents electrochemical active feature, electrochemical performance of the perovskite bismuth ferrite as an electrode material is improved by proper calcium ion doping in the aqueous basic electrolyte environment. For substantially promoting the electronic transport capabilities, Ca 2+ ions are used for substituting partial Bi 3+ ions at A site via introducing oxygen vacancies. The electrochemical performance suggests that utilization of 10% Ca 2+ doping (BFO-10%Ca) would offer 305.5 mAh g −1 at 1 A g −1. Specifically, the assembled BFO-10%Ca//graphene asymmetric energy storage devices could deliver a stable energy storage capability up to 3,000 cycles at a current density of 5 A g −1. The results indicate that heterogeneous ion doping would be an effective strategy for improving the electrochemical performance for energy storage application.

“…The development of nanotechnology has gained momentous attention since the size effects of nanostructures are beneficial towards the kinetics and thermodynamics of electrochemical reactions. [32,69,70] Ideal textural properties of a SC electrode includes the following: (1) large surface area, not only to provide more electroactive sites for faradaic reaction but also to enlarge the contact between electrode and electrolyte to enhance the specific capacitance; and (2) highly porous surface to facilitate the transport and diffusion of electrolyte ions and to accommodate the volume changes during the rapid chargedischarge process to improve the rate capability and cycling stability. The active surface with hierarchical mesoporous, nanopores inside mesopores, provides a more accessible pathway for electron/electrolyte movement.…”

Supercapacitors store electrical energy by ion adsorption at the interface of the electrode-electrolyte (electric double layer capacitance, EDLC) or through faradaic process involving direct transfer of electrons via oxidation/ reduction reactions at one electrode to the other (pseudocapacitance). The present minireview describes the recent developments and progress of carbon-transition metal oxides (C-TMO) hybrid materials that show great promise as an efficient electrode towards supercapacitors among various material types. The review describes the synthetic methods and electrode preparation techniques along with the changes in the physical and chemical properties of each component in the hybrid materials. The critical factors in deriving both EDLC and pseudocapacitance storage mechanisms are also identified in the hope of pointing to the successful hybrid design principles. For example, a robust carbon-metal oxide interaction was identified as most important in facilitating the charge transfer process and activating high energy storage mechanism, and thus methodologies to establish a strong carbon-metal oxide contact are discussed. Finally, this article concludes with suggestions for the future development of the fabrication of high-performance C-TMO hybrid supercapacitor electrodes.[a] Dr.

“…Due to overconsumption of non-renewable resources and the growing threat of global warming, reliable and clean energy supplies, such as the secondary battery and supercapacitor (SC) science and technology, are in urgent need of a breakthrough (Liu et al, 2016; Salanne et al, 2016; Liu M. et al, 2018; Liang et al, 2019). SCs are becoming more appealing than ever because of their rapid recharge capabilities, high power density, and durable life cycles (Salanne et al, 2016; Du et al, 2018; Kirubasankar et al, 2018; Ho and Lin, 2019; Le et al, 2019; Ma et al, 2019; Yang L. et al, 2019). It is well-established that three main electrode materials include conducting polymer, transition metal oxide, and carbon materials (Jabeen et al, 2016a,b; Chen et al, 2017; Li et al, 2018; Idrees et al, 2019).…”

Binary metal oxides composed of molybdenum–vanadium oxides are promising candidates for supercapacitors. Here, we report the synthesis of one-dimensional V0.13Mo0.87O2.935 nanowires through a facile one-step hydrothermal method. This nanowire presented a high specific capacitance of 394.6 F g−1 (1 mV s−1) as an electrode applied to the supercapacitor. Importantly, this electrode showed a perfect rate capability of 91.5% (2 to 10 A g−1) and a continuous verified outstanding cyclic voltammetry of 97.6% after 10,000 cycles. These superior electrochemical properties make the synthesized V0.13Mo0.87O2.935 nanowires a prospective candidate for high-performance supercapacitors.
