We developed an Raman spectroscopy method to visualize lithium deposition and diffusion at the microelectrode interface. Lithium deposition released free EC and FSA, while dissolution promoted rapid Li coordination. The estimated diffusion layer thickness matched theoretical predictions, highlighting micro-Raman spectroscopy's potential for studying lithium-ion battery interfaces.
我们开发了一种拉曼光谱方法，用于可视化微电极界面处锂的沉积和扩散。锂沉积释放出游离的碳酸乙烯酯（EC）和氟代磺酸锂（FSA），而溶解则促进了锂的快速配位。估计的扩散层厚度与理论预测相符，突出了显微拉曼光谱在研究锂离子电池界面方面的潜力。
