空心碳纳米球（HCN）在各种电化学存储器件中有着广泛的应用。中空结构的特点可以赋予碳电极材料良好的反应动力学，对结构变形的高机械依赖性，以及对功能材料的强大负载能力，这使得它们对于不同的储能系统特别感兴趣。本文综述了近年来HCNs的研究进展，重点介绍了HCNs的合成方法及其作为高性能锂离子电池后电极材料的应用。除了广泛应用的模板法外，还介绍了基于聚合物前驱体化学设计的自模板法。在合成过程中的形状演变机制，以及不同的方法对HCN的关键结构特征（如形状，成分和架构）的控制能力，也将突出显示。此外，我们还介绍了所制备的HCN在后锂离子电池中的典型应用，如锂硫电池、钠离子电池和钾离子电池。我们试图将电池性能与HCN的结构特征相关联，以便不仅充分利用形状控制的优势，而且还有助于理解新兴技术中的电荷存储机制。
Hollow carbon nanospheres (HCNs) have found broad applications in different kinds of electrochemical storage devices. The characteristic hollow structure can endow carbon electrode materials with good reaction kinetics, high mechanical reliance against structural deformation, and powerful capability toward loading functional materials, which makes them particularly interesting for different energy storage systems. In this review, we summarize the recent progresses made in the research of HCNs, focusing on the synthesis strategies and corresponding applications as high-performance electrode materials in post lithium-ion battery (LIB) systems. Besides the widely implemented template-based routes, self-template routes based on the chemical design of polymeric precursors are also introduced. Efforts directed toward the shape evolution mechanism during synthesis, as well as the control capability of different methodologies on the key structural features of HCNs (such as shape, compositions, and architectures), will also be highlighted. Furthermore, we introduce the representative applications of the prepared HCNs in post LIBs, such as lithium–sulfur batteries, sodium-ion batteries, and potassium-ion batteries. We attempt to correlate the battery performance with the structural characteristics of HCNs so as to not only make good use of the advantage of shape control, but also facilitate understanding regarding the charge storage mechanism in the newly emerging technologies.
