Lithium-ion batteries (LIBs) and sodium-ion batteries (SIBs) have received much attention in energy storage system. In particular, among the great efforts on enhancing the performance of LIBs and SIBs, yolk-shell (YS) structured materials have emerged as a promising strategy toward improving lithium and sodium storage. YS structures possess unique interior void space, large surface area and short diffusion distance, which can solve the problems of volume expansion and aggregation of anode materials, thus enhancing the performance of LIBs and SIBs. In this review, we present a brief overview of recent advances in the novel YS structures of spheres, polyhedrons and rods with controllable morphology and compositions. Enhanced electrochemical performance of LIBs and SIBs based on these novel YS structured anode materials was discussed in detail.
锂离子电池（LIBs）和钠离子电池（SIBs）在储能系统中备受关注。特别是，在提高LIBs和SIBs性能的诸多努力中，蛋黄壳（YS）结构材料已成为一种改善锂和钠存储的有前景的策略。YS结构具有独特的内部空隙空间、大表面积和短扩散距离，可解决负极材料的体积膨胀和团聚问题，从而提高LIBs和SIBs的性能。在本综述中，我们简要概述了具有可控形态和组成的球形、多面体和棒状新型YS结构的最新进展。详细讨论了基于这些新型YS结构负极材料的LIBs和SIBs增强的电化学性能。
