The structural design of electrode materials is one of the most important factors that determines the electrochemical performance of energy storage devices. In recent years, hollow micro-/nanoarray structures have been widely explored for energy applications due to their unique structural advantages. Their complex hollow interior and shell arrays enable fast ion diffusion/transport, provide abundant active sites and accommodate volume changes. Moreover, the direct contact of hollow arrays with substrates enhances the mechanical stability during long-term cycling. To date, huge progress has been achieved in the rational design of various hollow array architectures. However, a review on this topic has been rarely reported. Herein, the multifunctional merits and typical synthetic strategies for hollow array structures are analyzed in detail. Furthermore, their applications in electrochemical energy storage (such as supercapacitors and batteries) are summarized. The development and challenges of hollow arrays in terms of substrates, technique improvement and material innovation are discussed. Finally, their applications for energy storage and conversion are prospected.

中空阵列架构及其在电化学储能中的应用的最新进展。
电极材料的结构设计是决定储能装置电化学性能的最重要因素之一。近年来，中空的微/纳米阵列结构因其独特的结构优势而被广泛用于能源应用。它们复杂的中空内部和外壳阵列可实现快速的离子扩散/传输，提供丰富的活性位点并适应体积变化。而且，中空阵列与基板的直接接触增强了长期循环期间的机械稳定性。迄今为止，在各种空心阵列架构的合理设计方面已经取得了巨大的进步。但是，很少有对此主题的评论。在此，详细分析了中空阵列结构的多功能优点和典型的合成策略。此外，总结了它们在电化学能量存储（例如超级电容器和电池）中的应用。讨论了中空阵列在基板，技术改进和材料创新方面的发展和挑战。最后，展望了其在能量存储和转换中的应用。
