“…The porous structure of the CuNi-pSi sample was further disclosed by the N 2 adsorption-desorption isotherm curves (Figure 3b). The type III curve with an H3-type hysteresis loop is revealed, indicating the presence of a certain content of mesopores in the product [52]. The specific surface area of the material is about 25.08 m 2 g −1 , and the pore size is mainly between 1.7 and 10 nm (Figure 3c).…”

Due to its extremely high theoretical mass specific capacity, silicon is considered to be the most promising anode material for lithium-ion batteries (LIBs). However, serious volume expansion and poor conductivity limit its commercial application. Herein, dealloying treatments of spray dryed Al-Si-Cu-Ni particles are performed to obtain a Cu/Ni co-doped Si-based anode material with a porous nanowire network structure. The porous structure enables the material to adapt to the volume changes in the cycle process. Moreover, the density functional theory (DFT) calculations show that the co-doping of Cu and Ni can improve the capture ability towards Li, which can accelerate the electron migration rate of the material. Based on the above advantages, the as-prepared material presents excellent electrochemical performance, delivering a reversible capacity of 1092.4 mAh g−1 after 100 cycles at 100 mA g−1. Even after 500 cycles, it still retains 818.7 mAh g−1 at 500 mA g−1. This study is expected to provide ideas for the preparation and optimization of Si-based anodes with good electrochemical performance.

“…An important criterion for verifying the synthesis of HEOs is the single-phase structure, which can be confirmed by X-ray diffraction (XRD) analysis [75][76][77]. As shown in Figure 5a, Rost et al [19] used XRD to test the transformation process in the phase composition of the sample (a mixture of five kinds of oxides with equal atomic ratios) in an air ambient environment up to 1000 • C, during their first synthesis of (Mg,Ni,Co,Cu,Zn)O HEOs.…”

High-entropy oxides (HEOs), as a new type of single-phase solid solution with a multi-component design, have shown great potential when they are used as anodes in lithium-ion batteries due to four kinds of effects (thermodynamic high-entropy effect, the structural lattice distortion effect, the kinetic slow diffusion effect, and the electrochemical “cocktail effect”), leading to excellent cycling stability. Although the number of articles on the study of HEO materials has increased significantly, the latest research progress in porous HEO materials in the lithium-ion battery field has not been systematically summarized. This review outlines the progress made in recent years in the design, synthesis, and characterization of porous HEOs and focuses on phase transitions during the cycling process, the role of individual elements, and the lithium storage mechanisms disclosed through some advanced characterization techniques. Finally, the future outlook of HEOs in the energy storage field is presented, providing some guidance for researchers to further improve the design of porous HEOs.

“…This is due to the introduction of metal cations with different radii and charge states, resulting in lattice distortion or defects and more complex lattice structure. [36,37] Interestingly, when Mn and Ni were further introduced into the HESOs, the O V content decreased instead. This indicates that although more ions are introduced, HESOs has a more stable lattice structure due to the high-entropy stabilization effect, promoting the refilling of lattice vacancies and ultimately leading to a decrease in O V .…”

High‐entropy spinel oxides (HESOs) are a promising anode material for lithium‐ion batteries (LIBs) due to their high structural stability and theoretical capacity. However, the development of HESOs is currently mainly limited to five‐component equimolar systems, and the lithium storage mechanism is still controversial, which hinders the development and application of HESOs. A nonequimolar six‐component oxide with high Cr content, (CoMnZnNiMg)2CrO4, has been synthesized successfully using a solution combustion method. The prepared material is a high‐entropy oxide with a spinel structure, consisting of homogeneous nanoparticles with a mesoporous structure. As an anode material for LIBs, (CoMnZnNiMg)2CrO4 exhibits high rate performance (371 mAh g‐1 at 2000 mA g‐1) and long cycling stability (608 mAh g‐1 after 200 cycles at 200 mA g‐1). A variety of constituent elements exist uniformly and stably in a spinel phase due to the high configuration entropy induced phase stabilization effect, and the synergistic effect of the various valence elements in the material results in the excellent electrochemical performance. The outstanding electrochemical kinetic properties of the HESOs are mainly attributed to the high ionic diffusion coefficients and pseudocapacitance contributions. In addition, the HESOs electrodes undergo an amorphous conversion during the initial charge/discharge process. This study shows that the rational design and modulation of the active component is an effective way to obtain high‐performance HESOs for LIBs.This article is protected by copyright.
