Isoplots of the in-situ XRD scans taken from the anode side of the CaxSnǀǀ14PAQ cells during the first, second and from 201st to 203rd discharge/charge cycles with a specific current of 26 mA g−1 at 25 °C. The identity of each peak is shown along the top and the cell voltage profiles are shown on the left. ICSD-ID: Ca2Sn 659611, β-Sn 106072, CaSn3 58934, Ca36Sn23 54619 and CaO 26959.
