This project will develop embedded fibre-optic Raman probes that can be used for in-operando monitoring of chemical processes within Li:ion batteries. The probes are based on hollow-core optical fibres that avoid the large silica-Raman background that limits the use of conventional optical fibres in Raman spectroscopy. The project will investigate optimizing and automating Raman analysis of the electrolyte liquid, and potential signal enhancements by utilising optical and plasmonic phenomena.

该项目将开发嵌入式光纤拉曼探针，可用于锂离子电池内化学过程的运行监测。探头是基于空心光纤，避免了大的二氧化硅拉曼背景，限制了使用传统的光纤在拉曼光谱。该项目将研究电解质液体的优化和自动化拉曼分析，以及利用光学和等离子体现象增强潜在的信号。
