“…The separator samples were imaged using a Zernike phase contrast setting in a lab-based nano-scale X-ray microscope (Zeiss Xradia 810 Ultra, Carl Zeiss Microscopy, Pleasanton, CA), which emphasizes material edges by using phase shifts across the incident X-ray beam [30,40]. Fig.…”

Separators are an integral component for optimising performance and safety of lithium-ion batteries; therefore, a clear understanding of how their microstructure affects cell performance and safety is crucial. Phase contrast X-ray microscopy is used here to capture the microstructures of commercial monolayer, tri-layer, and ceramic-coated lithium-ion battery polymer separators. Spatial variations in key structural parameters, including porosity, tortuosity factor and pore size distribution, are determined through the application of 3D quantification techniques and stereology. The architectures of individual layers in multi-layer membranes are characterised, revealing anisotropy in porosity, tortuosity factor and mean pore size of the three types of separator. Detailed structural properties of the individual layers of multi-layered membranes are then related with their expected effect on safety and rate capability of cells.

“…Phase contrast is most commonly used for imaging materials that show poor absorption contrast i.e. biological matter, due to the low absorption cross sections of the light elements but has recently been applied to battery materials [14,15].…”

“…However, emerging technologies which use other contrast methods such as fluorescence [31], phase contrast [14], diffraction [32,33] and diffractive imaging techniques (the latter allows for spatial resolution no longer limited by the optical elements in the beam [34][35][36]) are also applied for studies of battery materials.…”

“…Eastwood et al and Lin et al have made use of the phase contrast to successfully image a graphite electrode with sub-µm resolution [14] or to understand the dissolution and re-deposition of polysulfides in lithium sulfur cells [15]. Another approach followed by Zielke et al was to model structures corresponding to low atomic number elements in combination with FFTXM tomography reconstructions [55].…”

“…Graphite electrodes are overwhelmingly the most popular anode in commercial cells, but have been challenging to image using conventional techniques [8]. This is because conventional absorption imaging typically provides insufficient contrast between the weakly absorbing graphite particles and the electrolyte in the filled pore space.…”

Batteries Imaging degradationThe degradation and failure of Li-ion batteries is strongly associated with electrode microstructure change upon (de)lithiation. Now, an operando X-ray tomography approach is shown to correlate changes in the microstructure of electrodes to cell performance, and thereby predict degradation pathways. Paul R. ShearingLi-ion batteries have revolutionised modern life, most notably through their use in consumer electronics, but also powering applications as diverse as medical implants, grid scale storage and satellites. In the future, battery technologies will continue to shape the way we live, from post Li-ion batteries for automotive applications, to off grid micro-generation systems to power our homes. However, with increasing concern regarding the safety and durability of batteries, fuelled by recent high profile failures, it is essential that materials scientists and engineers understand the fundamental degradation mechanisms. Writing in Nature Communications, Vanessa Wood and co-workers from Switzerland and Germany now report an advanced 3D X-ray imaging technique to explore the relationship between performance and microstructure for current and future generation battery materials [1].
