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.

中空碳纳米球:后锂离子电池的合成与应用

中空碳纳米球(HCN)在不同种类的电化学存储设备中已发现了广泛的应用。特有的中空结构可以使碳电极材料具有良好的反应动力学,对结构变形的高度机械依赖性以及强大的装载功能材料的能力,这使得它们对于不同的储能系统尤为有趣。在这篇综述中,我们总结了HCNs研究的最新进展,重点介绍了合成策略及其在后锂离子电池(LIB)系统中作为高性能电极材料的相应应用。除了广泛实施的基于模板的路线外,还介绍了基于聚合物前体化学设计的自模板路线。也将重点介绍针对合成过程中形状演化机制的努力,以及针对HCN关键结构特征(例如形状,成分和体系结构)的不同方法的控制能力。此外,我们介绍了制备的HCN在后LIB中的代表性应用,例如锂硫电池,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,而且还有助于了解新兴技术中的电荷存储机制。也将突出显示。此外,我们介绍了制备的HCN在后LIB中的代表性应用,例如锂硫电池,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,而且还有助于了解新兴技术中的电荷存储机制。也将突出显示。此外,我们介绍了制备的HCN在后LIB中的代表性应用,例如锂硫电池,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,而且还有助于了解新兴技术中的电荷存储机制。
