Abstract
The Li-S battery has the potential to replace Li-ion batteries in high capacity and high gravimetric energy density applications, but certain technical challenges result in diminished cycle life and have hindered its commercialization. Lab-scale X-ray micro-tomography was performed on an elemental sulfur electrode and a miniaturized in-situ tomography Li-S cell, and the 3D visualization achieved with this technique provides a wealth of information, improving understanding of the evolution of morphological and microstructural parameters of the different phases. As X-ray imaging is inherently non-destructive, it enables these parameters to be observed in-situ as a function of cycle life and state of charge. The inherently anisotropic nature of active material dissolution, recrystallization and other degradation processes within the electrode necessitates a three-dimensional approach to enable their visualization and quantification, and X-ray tomography is a useful tool in informing the development of more optimal electrode designs.
