Highly Ordered Mesoporous NiCo2O4 as a High Performance Anode Material for Li-Ion Batteries

The controlled synthesis of highly ordered mesoporous structure has attracted considerable attention in the field of electrochemistry because of its high specific surface area which can contribute the transportation of ions. Herein, a general nano-casting approach is proposed for synthesizing highly...
