“…Among the transition metal oxides, hematite (α-Fe 2 O 3 ) has attracted great interest due to its favorable properties, such as low cost, good stability, nontoxicity, and environmental friendly properties. It has been studied for applications in Li-ion batteries [7][8][9][10], supercapacitors [11][12][13], magnetic materials [14,15], catalytic agents [16], gas sensors and so on [17,18].…”

“…Hematite (α-Fe 2 O 3 ) holds great promise as a negative electrode for asymmetric supercapacitors (ASCs) because of its large theoretical specific capacitance and suitable working window in negative potential [73,74]. However, pure hematite materials are of limited application potential due to the low conductivity and power density [33,75].…”

“…As shown in Table II, the enhanced electrochemical performances of iron salts electrodes were achieved as compared to reported literatures. [21][22][23][24][25][26][27][28][29][30] All Fe 3+ cations at nanoscale can take part in the redox reactions, which can enhance the specific capacitance of electrode materials without hampering the power density.…”

Nanotechnology can highly promote the electrochemical performances of transition metal oxide pseudocapacitors on the basis of thermodynamic data and kinetic reaction processes. The working mechanism of pseudocapacitors is fast and revisable surface Faradaic reactions on the electrodes which differ from bulk redox reactions in lithium ion batteries. The nanostructured electroactive materials with high specific surface areas, which can be efficiently contact with electrolyte, show enhanced power density. Meanwhile, the nanostructured materials can elevate the utilization ratio of electroactive materials and highly promote the energy density of pseudocapacitors. Besides, nanostructured materials can short the transport paths for ions of electrolyte and electrons in the electrode system, change electrode potential by modifying the chemical potentials of electrolyte ions and electrons for very small particles, and have more extensive solid solutions for ions intercalation, which benefit the high electrochemical performance.
