“…[96] In this case, micro-short-circuit behavior in oxide SSEs may be dominated by internal lithium nucleation (lithium dendrites propagate through voids and grain boundaries with preferential ion pathways) rather than the electrochemo-mechanical damage/dendrite penetration behavior in sulfide SSEs. [99] Scalable sheet-type electrodes are necessary for the practical application of sulfide-based ASSBs. Due to their key role in maintaining microstructural integrity, binders are indispensable in the preparation of flexible electrodes.…”

Sulfide‐based all‐solid‐state batteries (ASSBs) are one of the most promising energy storage devices due to their high energy density and good safety. However, due to the volume (stress) changes of the solid active materials during the charging and discharging process, the generation and evolution of electrochemomechanical stresses are becoming serious and unavoidable problems during the operation of all‐solid‐state batteries due to the lack of a liquid electrolyte to partially buffer the stress generated in the electrodes. To understand these electrochemo‐mechanical effects, including the origins and evolution of mechanical or internal stresses, it is necessary to develop some highly sensitive probing techniques to measure them precisely and bridge the relationship between the electrochemical reaction process and internal stress evolution. Herein, recent progress on uncovering the origins of the internal stresses, the working principle and experimental devices for stress measurement, and the application of those stress‐measuring techniques in the study of electrochemical reactions in sulfide‐based ASSBs are briefly summarized and overviewed. The investigation of precise and operando monitoring techniques and strategies for suppressing or relaxing these electrochemomechanical stresses will be an important direction in future solid‐state batteries.

“…[1][2][3][4] However, the problem of poor cycle life due to uncontrolled lithium dendrite growth has severely limited the large-scale application of PEO-based SSLMBs. [5][6][7][8][9] The mechanical strength of PEO-based electrolytes is insufficient to inhibit lithium dendrite growth because the yield stress of lithium dendrites is as high as 244 MPa. [10][11][12][13] The promotion of the uniform deposition of lithium and effectively delaying the growth of lithium dendrites are the grand challenges in SSLMBs.…”

“…Studies looking at directionality of residual strain in metals have been primarily focused on cubic metals (Spolenak et al, 2003;Shen et al, 2022). In this study, we determine the directionality of the residual strain tensor of a hexagonal metal, titanium, with mXRD.…”

Previously, synchrotron X-ray Laue microdiffraction has been used to measure the magnitudes of residual strain in materials. Recently the method was advanced to determine the orientation of the strain ellipsoid and applied to naturally deformed quartzites; however, the deformation history of these quartzites is ambiguous due to their natural origin. In this study, synchrotron X-ray Laue microdiffraction (µXRD) is used to measure the residual strain for the first time in a sample with known stress history, rolled titanium. A deviatoric strain tensor is calculated from each Laue diffraction image collected with two µXRD scans of a rolled titanium sheet in different sample orientations. The principal strain axes are calculated using an eigen decomposition of the deviatoric strain tensors. The results show that the principal axis of compression is aligned with the normal direction of the titanium sheet, and the principal axis of extension is aligned with the rolling direction. Pole figures are used to represent the 3D distribution of residual strain axes.
