In situ characterization of O-dGNFs and O-dGZNFs. In situ TEM observations were conducted with an O-dGZNF sample. Time-resolved TEM images for a–d lithium insertion and e lithium extraction in real time. f–j Each SAED pattern corresponds to the TEM image above. k–m Magnified TEM images of featured states. n Curve of diameter change vs. time upon lithiation/delithiation. o In situ electrical conductivity measurement of O-dGNFs and O-dGZNFs during the lithiation process at three points, marked as state i, ii, and iii and corresponding to f, g, and i, respectively. p In situ EIS galvanostatic measurements during lithiation at 1.0 C-rate of O-dGNFs and O-dGZNFs. Scale bars: a 200 nm and f 5 1/nm
