Despite extensive research into novel materials, iron oxides remain fascinating and attract considerable attention because of their versatility, stability, ease of fabrication, low cost, natural abundance, and environmental friendliness. Because of their wealth of magnetic, optical, and electrical properties, iron oxides are particularly multifunctional materials that can be integrated into various devices. In this article, we will discuss the applications of iron oxide thin films in electronics (spintronics devices), energy (batteries and solar cells or photovoltaics), and sensors (gas, humidity, strain, biosensors, and so on). We begin with the most recent forms and fabrication methods for iron oxide thin film, as well as a fundamental understanding of the material. Additionally, the application constraints of these devices are discussed, and the challenges, solutions, and prospects for electronic devices based on iron oxide are outlined.

In Situ Electrochemical Impedance Measurements of α-Fe2O3 Nanofibers: Unravelling the Li-Ion Conduction Mechanism in Li-Ion Batteries

Unravelling the lithium-ion transport mechanism in α-Fe2O3 nanofibers through in situ electrochemical impedance studies is crucial for realizing their application in high-performance anodes in lithium-ion batteries. Herein, we report the effect of heat treatment conditions on the structure, composition, morphology, and electrochemical properties of α-Fe2O3 nanofibers as an anode for lithium-ion batteries. The α-Fe2O3 nanofibers were synthesized via electrospinning and post-annealing with differences in their annealing temperature of 300, 500, and 700 °C to produce FO300, FO500, and FO700 nanofibers, respectively. Improved electrochemical performance with a high reversible specific capacity of 599.6 mAh g−1 at a current density of 1 A g−1 was achieved after 50 cycles for FO700. The in situ electrochemical impedance spectroscopy studies conducted during the charge/discharge process revealed that the charge transfer and Li-ion diffusion behaviors were related to the crystallinity and structure of the as-synthesized α-Fe2O3 nanofibers. The surfaces of the α-Fe2O3 nanofibers were converted into Fe metal during the charging/discharging process, which resulted in improved electrical conductivity. The electron lifetime, as determined by the time constant of charge transfer, revealed that, when a conversion reaction occurred, the electrons tended to travel through the iron metal in the α-Fe2O3 nanofibers. The role of iron as a pseudo-resistor with negligible capacitance was revealed by charge transfer resistance analysis.
