Abstract

We report operando measurements of the Li-ion distribution in the anode and cathode of a coin-type all-solid-state battery in the charged and discharged states via Compton scattering using high-energy synchrotron radiation x-ray analysis. From the line shape pattern analysis of the Compton scattering x-ray spectrum, we accurately observed the Li-ion distribution within the cathode and anode during the charging/discharging of a real coin-shaped battery in an SUS casing. This study discusses the difference in Li-ion distribution between the cathode and anode and compares the Li-ion distribution of the battery after 20 charge–discharge cycles with those of a fresh battery.

利用康普顿散射 X 射线对全固态电池的锂离子分布进行操作性测量

我们报告了利用高能同步辐射 X 射线分析，通过康普顿散射测量硬币型全固态电池正负极在充放电状态下的锂离子分布。通过对康普顿散射 X 射线光谱的线形模式分析，我们准确地观测到了在 SUS 外壳中的真实硬币型电池在充放电过程中正负极内的锂离子分布。本研究讨论了正负极之间锂离子分布的差异，并比较了 20 次充放电循环后电池的锂离子分布与新鲜电池的锂离子分布。

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
