Abstract
Transition metal nitrides (TMNs), an encouraging and new class of emerging materials for energy storage devices, such as supercapacitors (SCs) and batteries, including Lithium-ion batteries (LIBs), Potassium-ion batteries (KIBs), Zn-air battery, Lithium-S battery (Li-S), Sodium sulfur (Na-S), and Lithium-O2 battery (Li-O2) due to their wide bandgap, flat and adjacent potential similar to lithium-metal, high capacity, superior conductivity, ideal chemical stability, and tunable structure. From this perspective, Fe2N is the best electrode for electrochemical energy storage devices due to its brilliant electrical conductivity, high capacity, environmental friendliness, low resistance, economical and natural abundance. Large strains, due to the nano-size effect, offer large exposed areas and more active centers for charge accommodations. In the existing literature, no single review article outlines the energy storage performance of adorable Fe2N, a rising star in the TMNs family, and its composite electrodes for advanced energy storage technologies. The recent research progress in Fe2N, Fe2N-based nanostructures for advanced SCs, LIBs together with Na-ion, Li-S, Na-S, KIBs, Li-O2, and Zn-air batteries are briefly oulined in this review report. Howevetr, a sustainable strategies, structural features of various nanostructured electrodes, and the current research progress are advocated for future evaluation.
