The development of cathode catalysts with a porous structure is essential to design Li-O-2 batteries with a high rate performance and good cycle stability. Herein, spinel-type porous cobalt-manganese oxide (Co-Mn-O) nanocubes derived from metal organic frameworks were employed as an electrocatalyst in a Li-O-2 battery. The battery with the porous Co-Mn-O nanocubes electrode showed a low overpotential and enhanced capacity. The synergistic effects of large specific surface area, porous structure, and the high electrocatalytic activity of the porous Co-Mn-O nanocubes electrode endowed the Li-O-2 battery with a good rate performance and excellent cycle stability up to 100 cycles.
