A one‐step, self‐supported topotactic transformation approach for synthesizing electrochemically active Co 3 O 4 needlelike nanotubes is reported. Used as the active material in the negative electrode of a rechargeable lithium ion battery, the Co 3 O 4 nanotubes manifest ultrahigh Li storage capacity with improved cycle life and rate capability. These features are discussed in terms of the unique structure of the materials.
