标题： EPR Imaging of Metallic Lithium

摘要： 我们提出了一种灵敏的表征方法，通过导电电子顺磁共振成像（CEPRI）来图像化锂离子电池组件中锂沉积物的微观结构。 该方法的通用性通过成像厚锂金属阳极的表面图案以及获得在隔膜内形成的锂枝晶的高分辨率图像得到证明，像素大小为几微米。 确定的枝晶空间分布可作为电流密度分布的指标，因此为电池单元设计提供了非常有价值的信息。 因此，这种方法展示了其在电子顺磁共振成像（EPRI）尚未被使用的研究领域中的能力。 显示英文摘要

摘要： We present a sensitive characterization method to image the microstructure of lithium deposits in lithium-ion battery components by Conduction Electron Paramagnetic Resonance Imaging (CEPRI). The versatility of the method is demonstrated for both, imaging surface-patterns of thick lithium metal anodes, as well as obtaining high-resolution images of lithium dendrites formed inside a separator with several micrometre pixel size. The determined spatial distribution of dendrites may then serve as an indicator of the current density distribution and, therefore, yields most valuable information for battery cell design. Accordingly, this method shows its capabilities in a research area where electron paramagnetic resonance imaging (EPRI) has not been utilized so far.
