High entropy alloys as electrode material for supercapacitors: A review

Evaluation of Entropy‐Stabilized (Mg0.2Co0.2Ni0.2Cu0.2Zn0.2)O Oxides Produced via Solvothermal Method or Electrospinning as Anodes in Lithium‐Ion Batteries

“…The ESM family includes alloys, [ 1,2 ] oxides, [ 9 ] and other composites, [ 10–15 ] which exhibit a variety of structures (rock‐salt, spinel, perovskite, fluorite…) and are endowed with enhanced properties that make them very promising candidates for a very wide range of applications, spanning from catalysis [ 16–24 ] to energy conversion and storage. [ 25–38 ]…”

“…[5] The ESM family includes alloys, [1,2] oxides, [9] and other composites, [10][11][12][13][14][15] which exhibit a variety of structures (rock-salt, spinel, perovskite, fluorite…) and are endowed with enhanced properties that make them very promising candidates for a very wide range of applications, spanning from catalysis [16][17][18][19][20][21][22][23][24] to energy conversion and storage. [25][26][27][28][29][30][31][32][33][34][35][36][37][38] Rock-salt (Mg 0.2 Co 0.2 Ni 0.2 Cu 0.2 Zn 0.2 )O was the first singlephase multicomponent oxide successfully synthesized, in 2015, via solid-state reaction from an equimolar mixture of MgO, CoO, NiO, CuO, and ZnO. [9] Since then, it has received very great attention and has been the focus of extensive research work.…”

MXene in core–shell structures: research progress and future prospects

“…17,18 Scientic studies of electrode materials such as carbon nanotubes, graphene oxide (GO), metal chalcogenides, metalorganic frameworks (MOFs), metal phosphides, high-entropy alloys, and layered hydroxides, and their progress in transiting towards hybrid materials and oriented structures have been signicant and well investigated throughout the years. [19][20][21][22][23][24][25][26][27] For example, transition metal oxides, [28][29][30][31][32] suldes, [33][34][35][36] porous carbon, 37 GO, 38 and reduced GO (rGO) are well-known 2D materials which have been utilized and evaluated in various applications. [39][40][41] 2D structures are desirable as they can act as protective shells or coatings, and also act as substrates to further grow nanomaterials.…”

Modified KBBF-like Material for Energy Storage Applications: ZnNiBO3(OH) with Enhanced Cycle Life

“…11−19 The difference between pseudocapacitive and battery-type electrode materials has been elaborated in our previous review. 20,21 Though unique and novel electrode materials have been consistently discovered, there are still new groups of active materials with prodigious properties that remain unexplored. 21−23 Two-dimensional (2D) materials, such as MXenes, graphene, metal organic frameworks, covalent organic frameworks, transition metal dichalcogenides, metal nitrides, layered double hydroxides, black phosphorus, and perovskite, have shown many applications in energy conversion/storage.…”

“…Generally, SC electrode materials are categorized according to three mechanisms: electric double layer capacitive (EDLCs-), pseudocapacitive-, and battery-type . Carbon-based materials, such as activated carbon (AC), carbon nanotubes, graphene, biomass-derived AC, carbon nanofiber, and so forth, store energy electrostatically on the interface of the electrode/electrolyte through the EDLC mechanism. , For pseudocapacitors and battery-type, various material candidates are based on polymers, transition metal oxides, transition metal chalcogenides, transition metal hydroxides, transition metal nitrides, transition metal phosphides, and transition metal carbides that store energy through redox reactions. − The difference between pseudocapacitive and battery-type electrode materials has been elaborated in our previous review. , Though unique and novel electrode materials have been consistently discovered, there are still new groups of active materials with prodigious properties that remain unexplored. − …”
