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

ABSTRACT: 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 ordered mesoporous NiCo₂O₄ microspheres. The as-synthesized mesoporous NiCo₂O₄ microsphere materials with high Brunner-Emmett-Teller (BET) surface area (~97.77 m²g^-1) and uniform pore size distribution around 4 nm exhibited a high initial discharge capacity of ~1,467 mAhg^-1, a good rate capability as well as cycling stability. The superior electrochemical performance was mainly because of the highly porous nature of Ni
