Abstract

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.

综述：基于卵黄壳结构的纳米材料的锂/钠离子电池增强阳极

摘要

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LIB和SIB性能的巨大努力中，蛋壳（YS）结构材料已成为改善锂和钠存储的一种有前途的策略。YS结构具有独特的内部空隙空间，较大的表面积和较短的扩散距离，可以解决阳极材料的体积膨胀和聚集问题，从而提高了LIB和SIB的性能。在这篇综述中，我们简要概述了球形，多面体和具有可控形态和成分的棒的新型YS结构的最新进展。详细讨论了基于这些新型YS结构阳极材料的LIB和SIB的增强电化学性能。
