“…[28][29][30] Due to the disorder arrangement of the multiple principal elements, HEOs exhibit excellent properties that traditional materials do not possess, such as superionic conductivity and excellent cycling stability. [31][32][33] Recently, the application of high-entropy oxides in the eld of energy storage has attracted the attention of researchers. According to reports, Sarkar et al applied the rock salt structured HEO (Mg 0.2 Co 0.2 Ni 0.2 Cu 0.2 Zn 0.2 )O to the anode material of lithiumion batteries for the rst time, and showed that it has almost no capacity loss aer 500 cycles.…”

“…The discharge capacity of the 6M-HEO-950 anode was 290 mAh•g −1 at the first cycle, which could remain at 233 mAh•g −1 after 5000 cycles at a high current density, which is 81% of the initial capacity. Compared to common HEO anodes, as shown in Table 1, the optimal 6M-HEO-950 anode in this study exhibited an outstanding ultra-long life [19,37,[42][43][44][45]. The cycling performance results confirm that the present optimal HEO electrode has high stability, mainly because of the following two factors.…”

Owing to the robust Li-ion storage properties induced by entropy stabilization effect, transition metal (TM)-based high-entropy oxides (HEOs) are promising electrode materials for highperformance Li-ion batteries (LIBs). In this study, a six-component Zn 0.5 Co 0.5 Mn 0.5 Fe 0.5 Al 0.5 Mg 0.5 O 4 spinel-structured HEO (denoted as 6M-HEO, where M = Zn, Co, Mn, Fe, Al, and Mg) was synthesized using a facile coprecipitation method. When used as an anode of the LIBs, its stable high-entropy nanostructures exhibit high specific capacity (290 mAh•g −1 at a current density of 2 A•g −1 ), ultra-long cycling stability (maintained 81% of the initial capacity after 5000 cycles), and outstanding rate performance. Such excellent performance can be attributed to two factors. Firstly, its high-entropy structure can reduce the stress caused by intercalation and avoid volume expansion of the HEO nanostructures. As a result, the cyclic stability was significantly enhanced. Secondly, owing to the unique element selection in this study, four active elements (Zn, Co, Mn, and Fe) were incorporated in inactive MgO and Al 2 O 3 matrice after the first discharge process, which would allow such high-entropy materials to withstand the rapid shuttle of Li ions.

Revolutionary changes in energy storage technology have put forward higher requirements on next-generation anode materials for lithium-ion battery. Recently, a new class of materials with complex stoichiometric ratios, highentropy oxide (HEO), has gradually emerging into sight and embracing the prosperity. The ideal elemental adjustability and attractive synergistic effect make HEO promising to break through the integrated performance bottleneck of conventional anodes and provide new impetus for the design and development of electrochemical energy storage materials. Here, the research progress of HEO anodes is comprehensively reviewed. The driving force behind phase stability, the role of individual cations, potential mechanisms for controlling properties, as well as state-of-the-art synthetic strategies and modification approaches are critically evaluated. Finally, we envision the future prospects and related challenges in this field, which will bring some enlightening guidance and criteria for researchers to further unlock the mysteries of HEO anodes.
