Abstract In this work, we put forward a facile yet efficient room‐temperature synthetic methodology for the smart fabrication of mesoporous nanocrystalline ZnMn 2 O 4 in macro‐quality from the birnessite‐type MnO 2 phase. A plausible reduction/ion exchange/re‐crystallization mechanism is tentatively proposed herein for the scalable synthesis of the spinel phase ZnMn 2 O 4 . When utilized as a high‐performance anode for advanced Li‐ion battery (LIB) application, the as‐synthesized nanocrystalline ZnMn 2 O 4 delivered an excellent discharge capacity of approximately 1288 mAh g −1 on the first cycle at a current density of 400 mA g −1 , and exhibited an outstanding cycling durability, rate capability, and coulombic efficiency, benefiting from its mesoporous and nanoscale structure, which strongly highlighted its great potential in next‐generation LIBs. Furthermore, the strategy developed here is very simple and of great importance for large‐scale industrial production.
