Rechargeable batteries have made important progress as an important means of sustainable development because of the non-renewable nature of fossil fuels has increased the demand for energy. As the “heart” of a rechargeable battery, the electrolyte directly determines the cycling performance of the battery. At present, electrolytes often have problems such as limited operating temperature and unsatisfactory ionic conductivity at room temperature. The introduction of electrode materials into the high-entropy strategy has improved the cycling performance of batteries, so the corresponding high-entropy electrolytes (HEEs) have high research value due to their disordered structure. However, there is still a lack of clear concepts and guidelines for efficient synthesis of HEEs, and the mechanism of corresponding performance improvement is unclear, which restricts the further development of HEEs. Herein, we summarize the application and working mechanism of HEEs in all-solid-state batteries. First, the development history and related definition of HEES are introduced. Then we discuss the application of HEES in existing solid electrolyte systems and its corresponding action mechanism, focusing on its improvement in ionic conductivity and interface wettability. Then, the current common synthesis methods and advanced characterization techniques of HEEs are introduced. Finally, the currently unsolved problems of HEEs and the corresponding potential development pathway are proposed. This review provides new ideas and insights for the study of high-performance solid-state electrolytes for commercial applications.

由于化石燃料的不可再生性增加了对能源的需求，可充电电池作为可持续发展的重要手段取得了重要进展。电解液作为可充电电池的“心脏”，直接决定了电池的循环性能。目前电解质常存在工作温度有限、室温离子电导率不理想等问题。高熵策略中电极材料的引入提高了电池的循环性能，因此相应的高熵电解质（HEEs）因其无序结构而具有很高的研究价值。然而，目前对于高效合成HEEs仍缺乏明确的概念和指导方针，相应的性能提升机制也不明确，制约了HEEs的进一步发展。本文综述了HEEs在全固态电池中的应用及其工作机理。首先，介绍了HEES的发展历史和相关定义。然后讨论了HEES在现有固体电解质体系中的应用及其作用机理，重点讨论了其对离子电导率和界面润湿性的改善。然后介绍了目前HEEs的常用合成方法和先进的表征技术。最后，提出了高等教育目前尚未解决的问题和相应的潜在发展路径。本文综述为高性能固态电解质的商业应用研究提供了新的思路和见解。

High-entropy alloy (HEA) nanomaterials have garnered extensive attention over the past few years for their intriguing properties over conventional simple alloys. The applications of HEA nanomaterials in electrocatalysis open prospective new avenues for catalyst discovery and performance optimization. The expansive compositional space, random atomic arrangement, and complex coordination environment endow HEA catalysts with tremendous tunability, which in turn calls for more effective and general design strategies in the catalysis community. An in-depth comprehension of the structure-performance relationship of HEA electrocatalysts is urgently needed to advance their reasonable development further. In this review, design methodologies of HEA nanomaterials are first discussed from four aspects, i.e., the composition, size, shape, and crystal structure, with the ultimate goal of achieving optimal catalytic activity, selectivity, and stability. Subsequently, recent progress in diverse electrochemical reactions, including hydrogen evolution, hydrogen oxidation, oxygen evolution, oxygen reduction, carbon dioxide reduction, alcohol oxidation and nitrate reduction, is summarized with a focus on the design principles of HEA catalysts toward specific reactions. Last, current tasks and future outlooks in this burgeoning field are proposed. Overall, this review is dedicated to leveraging the potential of HEA nanomaterials for efficient and sustainable energy storage and conversion.

Structural batteries are an emerging class of multifunctional electrochemical energy storage devices that combine mechanical load-bearing capabilities with energy storage. These batteries aim to address the weight and volume efficiency challenges faced by conventional batteries, particularly in electric vehicles, thereby extending driving range. As a crucial component of structural batteries, the electrolyte must not only facilitate ion transport but also provide mechanical integrity under flexural loads or impacts. However, developing a structurally strong electrolyte is a significant challenge, as high mechanical strength often leads to reduced ionic conductivity. Therefore, the full potential of structural batteries can only be realized once suitable multifunctional structural electrolytes are developed. This review examines the state-of-the-art in structural electrolytes, focusing on thermoplastic and thermoset polymer-based electrolytes for structural batteries. It explores the underlying ion transport mechanisms and mechanical enhancement strategies. The review also discusses how electrolyte composition—such as the choice of polymer matrix, inorganic fillers, solvents, and ionic liquid additives—affects both mechanical and electrochemical properties, as well as the role of interfacial stability. Furthermore, block copolymer electrolytes and molecular ion composite solid electrolytes based on rigid-rod polymers are proposed as promising candidates for structural electrolytes. The article also addresses the challenges and future prospects for these materials, aiming to provide insights into overcoming the limitations of polymer-based electrolytes with high mechanical strength, thus promoting their practical application in structural batteries.

结构电池是一种集机械承载能力与能量存储能力于一体的新型多功能电化学储能装置。这些电池旨在解决传统电池面临的重量和体积效率挑战，特别是在电动汽车中，从而延长行驶里程。作为结构电池的重要组成部分，电解质不仅要促进离子传输，而且要在弯曲载荷或冲击下保持机械完整性。然而，开发一种结构坚固的电解质是一项重大挑战，因为高机械强度通常会导致离子电导率降低。因此，只有开发出合适的多功能结构电解质，才能充分发挥结构电池的潜力。本文综述了结构电解质的最新研究进展，重点介绍了用于结构电池的热塑性和热固性聚合物电解质。它探讨了潜在的离子传输机制和机械增强策略。综述还讨论了电解质的组成，如聚合物基质、无机填料、溶剂和离子液体添加剂的选择，如何影响机械和电化学性能，以及界面稳定性的作用。此外，嵌段共聚物电解质和基于刚性棒聚合物的分子离子复合固体电解质被认为是结构电解质的有希望的候选者。本文还讨论了这些材料的挑战和未来前景，旨在为克服高机械强度聚合物电解质的局限性提供见解，从而促进其在结构电池中的实际应用。

Lithium-oxygen (Li-O₂) battery has gained wide interests as one potential energy storage solution for renewable energy due to its ultrahigh specific energy (∼3500 Wh kg^-1). Currently, its development has suffered from technical issues including poor rate capability, low round-trip efficiency and inferior cycling stability, which stem from the sluggish kinetics of oxygen reduction reaction and oxygen evolution reaction, irreversible formation/decomposition behavior of Li₂O₂ and parasitic reaction during discharge and charge processes. Thus, developing highly efficient electrocatalysts towards oxygen electrode reactions is urgently needed. In this review, we firstly discuss the basic structure and fundamental chemistry of Li-O₂ batteries. Key performance indexes of electrocatalyst are then highlighted and the effects of these key performance indexes of electrocatalysts on the surface and interface chemistry of oxygen electrode reactions in Li-O₂ battery are extensively clarified. Accordingly, the structure-performance relationships of different kinds of electrocatalysts are comprehensively discussed for non-aqueous Li-O₂ battery. Finally, we conclude with a summary on the challenges for achieving high-efficiency electrocatalysts and an outlook on pointing out the promising approaches for developing advanced oxygen electrocatalyst for Li-O₂ battery.

The construction of new energy sources and their energy storage systems will be a key part of achieving the goal of green and sustainable development. Aqueous zinc ion batteries (AZIBs) have gradually made significant development in large-scale energy storage with their excellent safety performance, low cost and long cycle life. MnO₂ have become one of the most promising cathode materials for AZIBs due to their high theoretical capacity, wide operating voltage, abundant raw material storage, and low cost. However, the energy storage mechanism of MnO₂ cathode has been controversial, while MnO₂ face inherent issues such as Jahn-Teller effect, poor transport dynamics and severe structure degradation. To make a breakthrough from the perspective of MnO₂ application, a comprehensive understanding of MnO₂ is urgent. Herein, we present the development, challenges and strategies of MnO₂ cathode materials for AZIBs in this review. Specifically, we first introduce the history of the development of MnO₂, from its initial application in alkaline batteries to the current high energy density batteries, followed by the discussions on the crystal structure, energy storage mechanism, main challenges and strategies. Finally, we provide innovative solutions to the bottlenecks in the development of MnO₂, as well as recommendations, conclusions and outlooks for its future research directions. We anticipate that in-depth research on MnO₂ will facilitate the commercialization of the next generation of high-performance AZIBs.

With the rapid advancement of the economy, the commercial landscape of lithium-ion batteries has expanded significantly. However, traditional graphite anodes are often inadequate for applications demanding high energy and power densities, such as in drones and electric vehicles, due to limited capacity and rate capability, necessitating enhancements. Emerging sodium and potassium-ion batteries, with resource availability estimated to be 1000 times that of lithium, are particularly suited for grid-level energy storage, supporting photovoltaic systems. Given the physical and chemical advantages of carbon materials, there has been increasing interest in advanced carbon structures for lithium-, sodium-, and potassium-ion batteries. Notably, 3D network of graphene offers pathways for enhanced ion diffusion and electron transport, and its expanded interlayer spacing holds promise for sodium and potassium storage, potentially improving capacity, power, and longevity as a binder-free anode. This review elucidates the preparation techniques for 3D-network graphene, examines its applications in alkali ion battery cathodes and anodes, and discusses future advancements in this area.

The layered bismuth oxyhalides (LBO)-based photocatalysts recently delivered exceptional potential in producing valued chemical energy through the photocatalytic CO₂ reduction process (PCRP). However, a comprehensive review is lacking which can simultaneously underscore recent activity rationalization and mechanism tracking of LBO-driven PCRP. So, we present a review that uncovers different innovative methods enabling the transitions of physicochemical and optoelectronic properties in LBO-based photocatalysts, leading to efficient PCRP. Wherein particular focus is on accelerating the charge carrier dynamics (e.g., electron/hole separation/transfer), minimizing the electron/hole recombination, refining the structure/morphology, and ensuring charge-localized active sites in LBO-based photocatalysts. Specifically, the review began with highlighting the significance of LBO-driven PCRP, its thermodynamical/kinetical aspects, PCRP-associated reaction pathways, PCRP reactor setup, and charge-transferring modes-based division of PCRP. Next, it unravels PCRP activity advancement and in-situ mechanism tracking by depicting exclusive recent examples. Finally, the challenges to LBO-driven PCRP, their solutions, and a feasible future outlook are underlined. This review may offer extendable aspects that could be applied to other materials for driving various redox reactions.

层状氧化卤化铋（LBO）基光催化剂最近通过光催化CO2还原过程（PCRP）在产生有价值的化学能方面表现出了非凡的潜力。然而，缺乏一项全面的综述，可以同时强调lbo驱动的PCRP最近的活动合理化和机制跟踪。因此，我们介绍了不同的创新方法，使lbo基光催化剂的物理化学和光电子性质的转变，从而导致高效的PCRP。其中特别关注的是加速电荷载流子动力学（例如，电子/空穴分离/转移），最大限度地减少电子/空穴重组，改进结构/形态，并确保lbo基光催化剂中的电荷局部化活性位点。具体来说，本文首先强调了lbo驱动的PCRP的重要性，它的热力学/动力学方面，PCRP相关的反应途径，PCRP反应器设置，以及基于PCRP的电荷传递模式的划分。接下来，它揭示了PCRP活性的进展和原位机制跟踪描绘独家最近的例子。最后，强调了lbo驱动的PCRP面临的挑战、解决方案和可行的未来前景。这一综述可能为其他材料驱动各种氧化还原反应提供可扩展的方面。
