“…The length of each plateau depends on the amount of charge provided by- or required for the corresponding reaction. In the most general case of a bare iron electrode in alkaline electrolyte, directly equivalent to the observations in the CV in Figure 22a, the galvanostatic charge-/discharge profiles show two plateaus, which refer to the oxidation of Fe to Fe(OH) 2 and Fe(OH) 2 to FeOOH/Fe 3 O 4 and vice versa [222,231,232]. Using the galvanostatic method, especially the coulombic efficiency of the investigated electrode may easily be derived by a direct comparison of the applied charge- and the resulting discharge capacity [96,173,233].…”

Metal-air batteries provide a most promising battery technology given their outstanding potential energy densities, which are desirable for both stationary and mobile applications in a “beyond lithium-ion” battery market. Silicon- and iron-air batteries underwent less research and development compared to lithium- and zinc-air batteries. Nevertheless, in the recent past, the two also-ran battery systems made considerable progress and attracted rising research interest due to the excellent resource-efficiency of silicon and iron. Silicon and iron are among the top five of the most abundant elements in the Earth’s crust, which ensures almost infinite material supply of the anode materials, even for large scale applications. Furthermore, primary silicon-air batteries are set to provide one of the highest energy densities among all types of batteries, while iron-air batteries are frequently considered as a highly rechargeable system with decent performance characteristics. Considering fundamental aspects for the anode materials, i.e., the metal electrodes, in this review we will first outline the challenges, which explicitly apply to silicon- and iron-air batteries and prevented them from a broad implementation so far. Afterwards, we provide an extensive literature survey regarding state-of-the-art experimental approaches, which are set to resolve the aforementioned challenges and might enable the introduction of silicon- and iron-air batteries into the battery market in the future.

“…For example, a main reason of the low utilization of iron is passivation by oxidized product. [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.…”

Influence of Polymer Coating on the Electrode Properties of Fe<sub>3</sub>O<sub>4</sub>/Carbon Nano-fiber Composite in Alkaline Electrolyte

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.
