结构复合材料和电化学储能是交通电气化的基础，但电动汽车的进步受到寄生电池质量的束缚。结构功率复合材料的出现，同时携带结构负载，同时存储电能的多功能材料，承诺在有效性能方面的显着改善。在这里，我们评估了关于结构超级电容器的文献，不仅提供了对组成（即，结构电极、结构电解质和结构隔膜）开发，而且还考虑制造、表征、放大、建模和设计/演示。我们对文献中报道的多功能性能数据进行了严格的分析，为读者提供了不同结构超级电容器开发之间的详细比较。最后，我们对结构超级电容器未来的研究和采用挑战进行了深入分析。要使这项技术成熟，必须解决几个重大障碍。这些包括开发可加工的结构电解质;优化电流收集以促进设备放大;识别负载传输封装解决方案;结构超级电容器的表征和排名的标准协议;结构超级电容器的预测多物理模型。通过解决这些问题，这些新兴的多功能材料将提供一种新的轻量化战略，有助于管理持续的气候危机。
Structural composites and electrochemical energy storage underpin electrification of transportation, but advances in electric vehicles are shackled by parasitic battery mass. The emergence of structural power composites, multifunctional materials that simultaneously carry structural loads whilst storing electrical energy, promises dramatic improvements in effective performance Here, we assess the literature on structural supercapacitors, not only providing a comprehensive and critical review of the constituent (i.e., structural electrode, structural electrolyte and structural separator) developments, but also considering manufacture, characterisation, scale-up, modelling and design/demonstration. We provide a rigorous analysis of the multifunctional performance data reported in the literature, providing the reader with a detailed comparison between the different structural supercapacitor developments. We conclude with insights into the future research and adoption challenges for structural supercapacitors. There are several significant hurdles which must be addressed to mature this technology. These include development of a processable structural electrolyte; optimisation of current collection to facilitate device scale-up; identification of load-transmitting encapsulation solutions; standard protocols for characterisation and ranking of structural supercapacitors and; predictive multiphysics models for structural supercapacitors. Through addressing such issues, these emerging multifunctional materials will deliver a novel lightweighting strategy that can contribute to managing the ongoing climate crisis.
