Abstract

As urbanization accelerates, the need for innovative solutions that integrate energy storage within the built environment (BE) becomes increasingly vital for sustainable and multifunctional infrastructure. This review paper delves into the pioneering concept of structural supercapacitors (SSCs), which seamlessly embed energy storage capabilities directly into construction materials such as ordinary portland cement, geopolymers, magnesium phosphate cement, aluminate cement, bricks, wood, and polymers. These materials are readily available and possess inherent structural strength, making them ideal candidates for functionalization as energy storage devices. SSCs rely on the combination of mechanical strength and electrochemical capabilities, allowing structures to serve dual functions—bearing mechanical loads while storing and releasing electrical energy. This review discusses the key components of SSCs, including conductive fillers, electrodes, and electrolytes, and evaluates their electrochemical and mechanical performance. Several critical research gaps have been identified, including the need for alternative conductive fillers to improve ionic conductivity and specific capacitance, advanced additives to enhance multifunctionality and optimization of the interaction between fillers and substrates. Additionally, post-curing treatments and the control of porosity and microstructure require further exploration to balance electrochemical performance with mechanical robustness. Challenges related to integrating SSCs into practical applications, such as environmental durability and mechanical load-bearing capacity, are also highlighted. Furthermore, the potential of 3D printing technology to create customizable SSC structures is identified as a promising area for future research. This review contributes to advancing SSCs and their potential integration into sustainable infrastructure by highlighting the gaps and future directions of the existing literature.

探索建筑兼容材料在建筑环境结构超级电容器储能方面的潜力
随着城市化进程的加快,在建筑环境(BE)中集成储能的创新解决方案对于可持续和多功能基础设施的需求变得越来越重要。本综述论文深入探讨了结构超级电容器(SSC)这一开创性概念,它将储能功能直接无缝嵌入普通硅酸盐水泥、土工聚合物、磷酸镁水泥、铝酸盐水泥、砖块、木材和聚合物等建筑材料中。这些材料随处可得,并具有固有的结构强度,是功能化为储能装置的理想候选材料。SSC 依靠机械强度和电化学能力的结合,使结构具有双重功能--承受机械负荷,同时存储和释放电能。本综述讨论了 SSC 的关键成分,包括导电填料、电极和电解质,并评估了它们的电化学和机械性能。研究发现了几个关键的研究空白,包括需要替代导电填料来提高离子导电性和比电容,需要先进的添加剂来增强多功能性,以及需要优化填料和基底之间的相互作用。此外,还需要进一步探索后固化处理以及孔隙率和微观结构的控制,以平衡电化学性能和机械坚固性。此外,还强调了与将 SSCs 集成到实际应用中有关的挑战,如环境耐久性和机械承载能力。此外,三维打印技术在创建可定制的 SSC 结构方面的潜力也被认为是未来研究的一个前景广阔的领域。本综述强调了现有文献中存在的不足和未来的研究方向,从而有助于推动南南合作及其与可持续基础设施的潜在结合。

期刊介绍: Cement & concrete composites focuses on advancements in cement-concrete composite technology and the production, use, and performance of cement-based construction materials. It covers a wide range of materials, including fiber-reinforced composites, polymer composites, ferrocement, and those incorporating special aggregates or waste materials. Major themes include microstructure, material properties, testing, durability, mechanics, modeling, design, fabrication, and practical applications. The journal welcomes papers on structural behavior, field studies, repair and maintenance, serviceability, and sustainability. It aims to enhance understanding, provide a platform for unconventional materials, promote low-cost energy-saving materials, and bridge the gap between materials science, engineering, and construction. Special issues on emerging topics are also published to encourage collaboration between materials scientists, engineers, designers, and fabricators.
