Fundamental study for carrier dynamics of batteries

本项目旨在研制一种用于锂离子电池载流子动力学分析的新型光电子显微镜(PEEM)样品盒。光电子显微镜是显示高横向分辨率局域电子结构的有力工具，对电池载流子动力学的研究具有重要意义。另一方面，对于锂离子电池的偏压施加、绝缘体和湿样品的研究，PEEM还没有得到很好的维持。在这里，我们计划设计和开发一种为电池量身定做的新型样品架，并着手直接分析电池接口。

This project is aimed to develop a new sample holder of photoemission electron microscope (PEEM) for detailed analysis of carrier dynamics in Li ion batteries. Photoemission electron microscopy is a powerful tool for the visualization of local electronic structure with high lateral resolution., and it would be useful for the investigation the carrier dynamics of batteries. On the other hand, PEEM is not yet well maintained for the study of Li ion batteries, i. e. bias application, insulator and wet specimens. Here, we planed to design and develop a new sample holder which is customized for batteries, and set out to direct analysis of battery interface.
