A novel carbon structure, highly branched homogeneous‐N‐doped graphitic (BNG) tubular foam , is designed via a novel N, N‐dimethylformamide (DMF)‐mediated chemical vapor deposition method. More structural defects are found at the branched portions as compared with the flat tube domains providing abundant active sites and spacious reservoirs for Li + storage. An individual BNG branch nanobattery is constructed and tested using in situ transmission electron microscopy and the lithiation process is directly visualized in real time.
