Aim of the project is a fundamental understanding of the structural and morphological processes in Li-air batteries and the development of a physico-chemical three-dimensional model of the electrode structures. Synchrotron X-ray tomography will be used to investigate the 3D structures in a Li-air battery in-operando during discharging/charging. The structural and morphological processes will be described quantitatively and the relevant structural parameters responsible for the battery properties will be identified. Together with in-operando impedance measurements a better fundamental understanding of the processes in the battery will be achieved. Based on the collected tomographic data the 3D structure model will be developed and later used for simulation studies. The simulations will help to understand the complex battery behaviour at different operating conditions and will be used for development of optimized electrode structures.

该项目的目的是从根本上了解锂空气电池的结构和形态过程，并开发电极结构的物理化学三维模型。同步加速器 X 射线断层扫描将用于研究锂空气电池在放电/充电过程中的 3D 结构。将定量描述结构和形态过程，并确定影响电池性能的相关结构参数。结合操作中阻抗测量，可以更好地了解电池中的过程。根据收集到的断层扫描数据，将开发 3D 结构模型，并随后用于模拟研究。模拟将有助于了解不同操作条件下的复杂电池行为，并将用于开发优化的电极结构。
