Hollow nanostructured anode materials lie at the heart of research relating to Li-ion batteries, which require high capacity, high rate capability, and high safety. The higher capacity and higher rate capability for hollow nanostructured anode materials than that for the bulk counterparts can be attributed to their higher surface area, shorter path length for Li(+) transport, and more freedom for volume change, which can reduce the overpotential and allow better reaction kinetics at the electrode surface. In this article, we review recent research activities on hollow nanostructured anode materials for Li-ion batteries, including carbon materials, metals, metal oxides, and their hybrid materials. The major goal of this review is to highlight some recent progresses in using these hollow nanomaterials as anode materials to develop Li-ion batteries with high capacity, high rate capability, and excellent cycling stability.
中空纳米结构阳极材料是锂离子电池相关研究的核心，锂离子电池需要高容量、高倍率性能和高安全性。中空纳米结构阳极材料相比于块状对应物具有更高的容量和更高的倍率性能，这归因于它们更大的表面积、Li(+)传输的更短路径长度以及体积变化的更多自由度，这可以降低过电位并在电极表面实现更好的反应动力学。在本文中，我们综述了锂离子电池中空纳米结构阳极材料的近期研究活动，包括碳材料、金属、金属氧化物及其混合材料。本综述的主要目标是突出在使用这些中空纳米材料作为阳极材料来开发具有高容量、高倍率性能和优异循环稳定性的锂离子电池方面的一些最新进展。
