Fig. 3

Dynamic gliding and transverse movement (“climbing”) of a c/2[001] dislocation during delithiation. a–d Time-lapsed high-resolution episcopic microscopy (HREM) images. e–h Corresponding Fourier-filtered images of a–d, showing only the (001) lattice plane fringes. Gliding, climbing, and merging of the dislocations towards the surface prompts the formation and release of O2 gas. The scale bar is 5 nm
