For the LFP microbeam diffraction experiment, a similar setup was used as described in van Hulzen et al. . The LFP||Li half-cells were prepared as pouch cells and fixed in a clamp with a conic opening on both sides to allow the X-ray beam to pass through. A monochromatic X-ray beam with wavelength 0.2852 Å (energy 43.47 keV) and spot size of ~1 micron was used to register the diffraction patterns on an Eiger2 X CdTe 4M detector with 2068 x 2162 pixels. To increase the number of grains in Bragg condition the sample was rotated along the z-axis (perpendicular to the beam). For all measurements the total rotation was 5° with a step size of 0.05° and an exposure time of 0.05 seconds, collecting 101 frames in about 6 seconds. To mitigate beam damage four locations were probed by rotation resulting in a time resolution of about 30 seconds per location.
