The development of Li focused ion beams (Li-FIB) enables controlled Li ion insertion into materials with nanoscale resolution. We take the first step toward establishing the relevance of the Li-FIB for studies of ion dynamics in electrochemically active materials by comparing FIB lithiation with conventional electrochemical lithiation of isolated β-Sn microspheres. Samples are characterized by cross-sectioning with Ga FIB and imaging via electron microscopy. The Li-FIB and electrochemical lithiated Sn exhibit similarities that suggest that the Li-FIB can be a powerful tool for exploring dynamical Li ion-material interactions at the nanoscale in a range of battery materials.

编辑推荐通讯——纳米级聚焦离子束与β-Sn微球电化学锂化的比较

锂聚焦离子束 (Li-FIB) 的发展能够以纳米级分辨率将锂离子可控地插入材料中。我们迈出了第一步，通过比较 FIB 锂化与孤立的 β-Sn 微球的常规电化学锂化，建立 Li-FIB 与电化学活性材料中离子动力学研究的相关性。样品的特征在于用 Ga FIB 进行横截面和通过电子显微镜成像。Li-FIB 和电化学锂化 Sn 表现出相似之处，表明 Li-FIB 可以成为探索一系列电池材料中纳米级动态锂离子材料相互作用的有力工具。
