论文摘要
Si-Anodes长期以来一直是候选人，这要归功于与石墨相比的容量增长十倍。但是，控制其降解的机制的细节仍然难以捉摸，阻碍了长期基于SI的阳极的科学指导的发展。在这里，我们演示了冷冻原子探针断层扫描中的最新发展如何使电极和电解质的深入分析以及它们在原子级的界面。
Si-anodes have long been candidates thanks to an expected ten-fold increase in capacity compared to graphite. However, details of the mechanisms governing their degradation remain elusive, hindering science-guided development of long-lived Si-based anodes. Here we demonstrate how the latest developments in cryo-atom probe tomography enable the in-depth analysis of the electrode and electrolyte, and their interface at atomic-level.
