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。

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.

随着经济的快速发展，锂离子电池的商业前景显著扩大。然而，由于容量和速率能力有限，传统的石墨阳极通常不适用于要求高能量和功率密度的应用，例如无人机和电动汽车，因此需要改进。新兴的钠离子和钾离子电池，其可用资源估计是锂离子电池的1000倍，特别适合电网级储能，支持光伏系统。鉴于碳材料的物理和化学优势，人们对锂离子、钠离子和钾离子电池的先进碳结构越来越感兴趣。值得注意的是，石墨烯的3D网络提供了增强离子扩散和电子传递的途径，其扩大的层间间距有望用于钠和钾的存储，潜在地提高了作为无粘合剂阳极的容量、功率和寿命。本文综述了三维网络石墨烯的制备技术，探讨了其在碱离子电池阴极和阳极中的应用，并讨论了该领域的未来发展。

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。

Proton exchange membrane fuel cell (PEMFC) is an electrochemical energy conversion system with remarkable efficiency and eco-friendly operation. It holds immense promise and application potential in facilitating the transition towards sustainable energy solutions. Nevertheless, the widespread commercial adoption of PEMFCs is hindered by the immaturity of individual components within the system. Chief among these obstacles are the high cost and inadequate activity of the cathode catalyst, limited proton conductivity of the PEM, and fuel starvation issues at the anode. Furthermore, concerns regarding the mass transport limitation and the degradation of the membrane electrode assembly (MEA) during practical operation collectively impede performance optimization and lifetime extension. Despite the advancements in delicate catalyst design, the complex synthesis processes coupled with trial-and-error methodologies complicate scalability for large-scale applications. In response to these multifaceted challenges, incorporating functional additives (FAs) has emerged as a promising and versatile strategy. These smart additives, with diverse and unique functions, have rapidly gained traction and are being applied across nearly all components of the MEA. However, research efforts to utilize FAs to achieve high-performance and durable PEMFCs are not comprehensively documented, particularly concerning the underlying operational mechanisms. This review aims to bridge this knowledge gap by consolidating current understanding, providing a detailed analysis of the diverse mechanisms at play, and highlighting both the merits and limitations associated with the FA strategy. We aspire to offer valuable insights into this emerging field and contribute to the innovation of next-generation functional additives tailored for advanced PEMFC systems.

质子交换膜燃料电池（PEMFC）是一种高效、环保的电化学能量转换系统。它在促进向可持续能源解决方案过渡方面具有巨大的前景和应用潜力。然而，pemfc的广泛商业应用受到系统内单个组件不成熟的阻碍。这些障碍主要是阴极催化剂的高成本和活性不足，PEM的质子导电性有限，以及阳极的燃料短缺问题。此外，在实际操作过程中，对质量传输限制和膜电极组件（MEA）退化的担忧共同阻碍了性能优化和寿命延长。尽管精致的催化剂设计取得了进步，但复杂的合成过程加上试错方法使大规模应用的可扩展性复杂化。为了应对这些多方面的挑战，加入功能性添加剂（FAs）已成为一种有前途的通用策略。这些智能添加剂具有多样化和独特的功能，已迅速获得牵引力，并被应用于MEA的几乎所有组成部分。然而，利用fa来实现高性能和耐用的pemfc的研究工作并没有全面的记录，特别是关于潜在的操作机制。这篇综述旨在通过巩固现有的理解来弥合这一知识差距，提供对不同机制的详细分析，并强调与FA策略相关的优点和局限性。我们渴望在这一新兴领域提供有价值的见解，并为先进PEMFC系统量身定制的下一代功能添加剂的创新做出贡献。

Although proton exchange membrane fuel cells (PEMFCs) have become a potential replacement for traditional energy sources because of their minimal environmental impact and superior efficiency, their vulnerability to degradation caused by in situ generated peroxide and oxygen radical species has seriously hindered their widespread application. To mitigate the negative effects of chemical attack on components of PEMFCs, especially on proton exchange membranes (PEMs), there has been significant efforts devoted in employing antioxidant strategies as the preferred solution, which can directly eliminate and remove harmful peroxide and oxygen radical species. However, due to the rigorous operating conditions, such as low pH, electric potential, water flow, and ion exchange/concentration gradient, undesirable degradation occurred for antioxidant additives. Moreover, the diminished activity and capability of antioxidants resulting from alterations in the physical state, such as migration, agglomeration, and dissolution, are also crucial factors to be taken into account. In this review, we mainly focus on the recent advancements in antioxidant therapy in enhancing the durability of PEMs, especially offering a comprehensive overview of advanced techniques for designing synthetic compounds and conducting thorough analyses of antioxidants to enhance activity-stability factors, aiming to inspire further advancements in this exciting field.

尽管质子交换膜燃料电池（pemfc）因其对环境影响小、效率高而成为传统能源的潜在替代品，但其易被原位生成的过氧化氢和氧自由基降解，严重阻碍了其广泛应用。为了减轻化学攻击对质子交换膜（pemcs）组分的负面影响，特别是对质子交换膜（pemms）的负面影响，人们一直致力于采用抗氧化策略作为首选解决方案，它可以直接消除和去除有害的过氧化氢和氧自由基。然而，由于苛刻的操作条件，如低pH值、电位、水流量和离子交换/浓度梯度，抗氧化添加剂会发生不良降解。此外，由于物理状态的改变，如迁移、团聚和溶解，抗氧化剂的活性和能力下降也是需要考虑的关键因素。本文主要综述了近年来抗氧化治疗在提高PEMs耐久性方面的研究进展，重点介绍了设计合成化合物和深入分析抗氧化剂以提高活性稳定性因素的先进技术，旨在激发这一令人兴奋的领域的进一步发展。

Metal–organic frameworks (MOFs) have attracted significant attention due to their tunable structures and ease of functionalization. However, the predominance of micropores in most MOFs limits their effectiveness in diffusion-controlled applications. Recent developments in the construction of hierarchically ordered macro-/mesoporous MOFs, as well as their composites and derivatives, have broadened the application scope of traditional MOF-based materials. These ordered meso-/macropore structures enhance the exposure of active sites and improve mass transfer efficiency, thereby boosting reaction performance. This review discusses recent advancements in the design, synthesis, and catalysis and energy applications of ordered macro-/mesoporous MOF-based materials. Compared to conventional microporous materials, ordered macro-/mesoporous MOF-based materials demonstrate superior performance in applications including photo-, electro-, and thermocatalysis and electrochemical energy storage. The review also explores current challenges and future direction in the development of ordered macro-/mesoporous MOF-based materials, providing valuable insights for creating new materials with greater efficiency and broader applicability.

The comprehensive and efficient utilization of lignocellulosic biomass is of great significance to humanity due to its low-carbon and sustainable characteristics. Hydrothermal treatment is a low-carbon technology for the valorization of lignocellulosic biomass toward diverse value-added bioproducts through the disintegration and conversion of lignocellulosic biomasses. This review first introduces the chemical compositions of lignocellulosic biomasses and the operating principles of hydrothermal treatment. Then, the transformation of the chemical compositions during hydrothermal treatment (<300 °C) is elucidated comprehensively. In addition, the recent advances in the hydrothermal valorization of lignocellulosic biomass into bio-oil, wood vinegar, briquette fuels, absorbents, carbonaceous electrode materials, and catalysts are introduced and discussed emphatically. The bridge between the hydrothermal treatment and the physicochemical properties and performances of the obtained value-added bioproducts is further built. The precise removal of chemical compositions and the followed directional conversion are the keys affecting the structure and physiochemical properties of the bioproducts. It is difficult to regulate the extraction and decomposition of chemical compositions in one step because of the heterogeneous structure and recalcitrant cross-linking barrier of lignocellulosic biomass. In this regard, a multi-step process is promising undoubtedly, while tailoring the specific application is necessary for industrialization due to the diversity of bioproducts. The future direction of fully efficient utilization of lignocellulosic biomass is proposed for the researches on the multipurpose valorization of high-value-added bioproducts. We believe this review would provide valuable guidance for the exploitation of biomass-derived high-value-added bioproducts through multipurpose production processes, ideally towards the achievement of a low-carbon blueprint.
