The focus of the project is to develop and understand the fundamentals of electrode-electrolyte interfaces in battery cells based on the sodium metal chloride technology developed by LiNa energy, as an alternative to Li Ion batteries. The interfaces of the cells will be investigated through in-situ and in-operando techniques, such as secondary ion mass spectrometry, X-ray photoelectron spectroscopy and electron microscopy, in order to not only understand their features but to obtain detailed information on the outermost atomic surface and the chemical variation in the immediate subsurface region (1-10 nm). Through this a comprehensive understanding of the battery and its electrochemical performance, with respect to the chemical evolution of the interfaces, can be ascertained.

该项目的重点是开发和了解基于丽娜能源开发的金属氯化钠技术的电池中电极-电解质界面的基本原理，作为锂离子电池的替代品。通过二次离子质谱、x射线光电子能谱和电子显微镜等原位和操作技术对细胞的界面进行研究，不仅可以了解其特征，还可以获得最外层原子表面的详细信息以及直接亚表面区域（1-10 nm）的化学变化。通过这种方法，可以确定对电池及其电化学性能的全面了解，以及界面的化学演变。
