Different Dimensional Nanostructured Silicon Materials: From Synthesis Methodology to Application in High‐Energy Lithium‐Ion Batteries

Nanostructured silicon is regarded as one of the most promising next‐generation anode materials for lithium‐ion batteries (LIBs) due to its high capacity and proper working voltage. However, the complexity in preparing nanostructured silicon and the large volume change in silicon during lithiation and delithiation impedes its commercial application. Herein, the recent progresses relating to nanostructured Si‐based anode materials are reviewed. The preparation of nanostructured silicon from dimensionality and methodology is mainly focused on, and the impactful works on silicon‐based anodes, as well as the recent research directions in this field, are outlined. Finally, key lessons from the successes so far are reviewed, and further perspectives to enable the application of silicon‐based anodes in practical LIBs are offered.
