“…6. Before recording each spectrum, the electrode was first kept at the applied potential to equilibrate for 300 s. The corresponding Naquist plot can be as Figure 5 and 6 and we can confirm that the impedance curve with respect to frequency is a hyperbola suggesting porous pore electrode due to adsorption of graphene molecules on Fe 3 O 4 electrodes [15].…”

Fe/Fe 3 O 4 /Graphene composite electrode material was synthesized by a thermal reduction method and then used as anode material along with Nickel cathode in rechargeable Ni/Fe alkaline batteries in hybrid electric vehicles. Reduced graphene /Fe/Fe 3 O 4 composite electrode material was prepared using a facile three step synthesis involving synthesis of iron oxalate and subsequent reduction of exfoliated graphene oxide and iron oxalate by thermal decomposition method. The synthesis approach presents a promising route for a large-scale production of reduced graphene /Fe/Fe 3 O 4 composite as electrode material for Ni/Fe rechargeable batteries. The particle size and structure of the samples were characterized by SEM and XRD.

“…19 Other major problems like low active material utilization and passivation induced capacity decay may take place. To subdue these problems, nano iron materials and nano-carbon composites have been used; [24][25][26][27][28] albeit particle agglomeration and increased hydrogen evolution were found to be the primary causes of failure to achieve several charge/discharge cycles. 24,29,30 C-Y Kao et al 31 have recently reported a nano iron/copper composite material with high concentration of Cu displaying a high rate discharge capacity of 800 mAh g −1 and at a mass activity of 3200 mA g −1 .…”

In this work, we have studied a 2% copper substituted core shell type iron/iron carbide as a negative electrode for application in energy storage. The NanoFe-Fe 3 C-Cu delivered 367 mAh g −1 at ≈80% current efficiency, successfully running for over 300 cycles. The superior electrode kinetics and performance were assessed by rate capability, galvanostatic, potentiodynamic polarization measurements in 6 M KOH electrolyte and at ambient temperature. Ex-situ XRD characterizations and SEM images of both the fresh and used electrode surfaces show that nanoparticles were found to be still intact with negligible particle agglomeration. The electrodes have shown stable performances with low capacity decay, whereas sulfur dissolution from the additive Bi 2 S 3 was found to decrease the charging efficiency with time. This core-shell type structured nano material is, consequently, an auspicious anode candidate in alkaline-metal/air and Ni-Fe battery systems. Electricity generation away from fossil fuels by renewable energy resources (RER) is increasing at a remarkable pace both as a means of mitigating greenhouse gas emissions as well as offsetting the global energy demand for sustainable development. Since the end of the 1990s, the world cumulative energy generation by both wind and solar has shown an exponential growth rate. In 2015, the global installed capacity of photovoltaics was 227.1 GW an increase by 25% and the total installed wind power was 432.9 GW, a rise by 17% compared to 2014 for both energy systems.1,2 However, both wind and solar are very dependent on weather conditions and there is a high quest for electrical energy storage (EES) for integration with these renewables. The variability in energy output is due to the stochastic nature and availability of the renewable sources, unreliable demand and supply of electricity, distributed energy generation, maintenance and utilization of load balance in peak shaving and leveling, stabilization of transmission and distribution to the grid, uninterruptable power supply with frequency control, voltage fluctuations and energy arbitrage. EES is considered to be vital and indispensable technology for both utility and transport applications.1,3-7 Among EES technologies, electrochemical energy storage systems in the form of batteries have characteristic features in the form of modularity and scalability, fast response time and high energy efficiency, although they do significantly differ in energy and power densities, charge and discharge duration, cycling behavior and capital cost.There are several rechargeable (secondary) battery energy storage systems (BESS) that are widely used or are under demonstrations/development phases and these among others include; lead-acid, Li-ion, the nickel-based batteries (Ni-MH, Ni-Cd, Ni-Fe, Ni-Zn, NaNiCl 2 ), redox flow batteries (Vanadium, Zn-Br, Zn-Cl, Zn-Ce, FeCr, V-Br), NaS and Air-metal batteries (Fe-air, Zn-air, Li-air, Mgair).6-10 The last type of "batteries" are essentially a hybridization of anodes in the form of metals and a f...

“…[4][5][6][7] Several attempts have been made to improve iron utilization, mainly by compositization with a conductive agent. [8][9][10][11][12][13] Particularly, the authors have made attempts to carbon nanofiber (CNF) having high conductivity and mechanical strength along the fiber axis. 14 Iron utilization has been improved up to 400 mAh per unit mass of iron: half of the theoretical capacity, by the optimum design of composite electrodes of nano-sized iron species loaded on a CNF surface, and the fabrication of such composites using sol-gel precipitation or ultrasonic-aided mixing of nano-sized magnetite (Fe 3 O 4 ) and CNF.…”

A composite of nano-Fe 3 O 4 and carbon nanofiber (CNF), which has been investigated to maximize iron utilization, is adversely affected by shortcomings such as hydrogen evolution by-reactions, high overpotential, self-discharge, and capacity fade by cycles. Hydrogen evolution from the Fe 3 O 4 /CNF electrode can be inhibited by coating with a polymer such as poly(ethylene glycol). Although self-discharge is not high, even modified Fe 3 O 4 /CNF electrodes are hindered by overpotential and cycle degradation deriving from partial dissolution of divalent iron and its subsequent aggregation.
