| Various electrochemical and electrophoretic deposition methods have been applied to the fabrication of various nanostructured electrodes for efficient Li-ion intercalation. Nanostructured electrodes include nanorod, nanotube, and nanocable arrays as well as coherent mesoporous nanocomposites fabricated by means of (1) template-assisted electrochemical or sol electrophoretic deposition, (2) anodic oxidation, and (3) potentiodynamic deposition. Such nanostructured electrodes possess huge surface area and short transport distance with added freedom for dimension change, and thus have demonstrated to be ideal structure for energy storage via lithium insertion. In comparison to the typical film electrode, nanostructured electrodes have significantly enhanced storage capacity and kinetics (up to 2 orders of magnitude). Our most recent work on the fabrication and Li-ion intercalation properties of coherent mesoporous carbon - oxide nanocomposites will be discussed as well. |
