摘要

同步辐射已成为探测可充电电池结构变化的常用方法，特别是用于operando分析。在此，我们报告了在operando研究中，电极暴露于高光子通量下，关闭电极辐照区域的电化学转化，并在operando光束位置周围引起锂化梯度。我们通过辐射诱导电离和电解质分解来合理化这种束损伤。

X-ray Beam Damage Effects in a Lithium-Ion Battery Probed by Spatially Resolved X-ray Diffraction

The use of synchrotron radiation has become common for probing the structural changes in rechargeable batteries, particularly for operando analysis. Herein, we report the exposure of the electrode to high photon flux during an operando study shutting down electrochemical transformations in the irradiated area of an electrode and causing a gradient of lithiation around the operando beam position. We rationalize such beam damage through radiation induced ionization and, consequently, electrolyte decomposition.

期刊介绍： ACS Energy Letters is a monthly journal that publishes papers reporting new scientific advances in energy research. The journal focuses on topics that are of interest to scientists working in the fundamental and applied sciences. Rapid publication is a central criterion for acceptance, and the journal is known for its quick publication times, with an average of 4-6 weeks from submission to web publication in As Soon As Publishable format. ACS Energy Letters is ranked as the number one journal in the Web of Science Electrochemistry category. It also ranks within the top 10 journals for Physical Chemistry, Energy & Fuels, and Nanoscience & Nanotechnology. The journal offers several types of articles, including Letters, Energy Express, Perspectives, Reviews, Editorials, Viewpoints and Energy Focus. Additionally, authors have the option to submit videos that summarize or support the information presented in a Perspective or Review article, which can be highlighted on the journal's website. ACS Energy Letters is abstracted and indexed in Chemical Abstracts Service/SciFinder, EBSCO-summon, PubMed, Web of Science, Scopus and Portico.
