金属锂的电沉积是锂电池失效的主要原因。首次以亚微米分辨率表征了液体电解质中电沉积锂“苔藓”的3D微观结构。使用同步辐射X射线相衬成像，我们区分苔藓状金属锂微结构从高表面积锂盐形成的对比X射线衰减。
The electrodeposition of metallic lithium is a major cause of failure in lithium batteries. The 3D microstructure of electrodeposited lithium 'moss' in liquid electrolytes has been characterised at submicron resolution for the first time. Using synchrotron X-ray phase contrast imaging we distinguish mossy metallic lithium microstructures from high surface area lithium salt formations by their contrasting X-ray attenuation.
