a Schematic diagram showing the in situ TEM experimental setup of a dry electrochemical cell. b STEM image series captured in real-time showing Pred volume expansion during sodiation. Scale bar is 200 nm. c Simulated SOS according to the Pred morphological evolution of the region labelled with the blue rectangle in b. d EDS maps of phosphorus (green), sodium (yellow), and carbon (red) elements of the region labelled with the red rectangle in b. Scale bar is 200 nm. e The length change of four Pred segments marked in b as the function of time during the sodiation process.
