Porous binary metal oxides with high theoretical specific capacities and power density are attracting increasing attentions as anode materials for high-performance lithium-ion batteries. Herein, we report a facile strategy for the synthesis of porous MnCo2O4 nanowires through direct calcination of metal–organic frameworks in air. The resulting MnCo2O4 nanowires exhibited enhanced lithium-storage performance (929 mAh g−1 at 100 mA g−1 after 100 cycles). The outstanding lithium-storage performances of the resulting MnCo2O4 nanowires can be ascribed to their unique porous architectures, which offer a proximate pathway for the transfer of electrolyte and electrons over long cycling periods.
