Metal-organic frameworks with open metal sites provide strong interaction sites for guest molecules, thus enriching the population of O2 in the pores significantly when employed as the electrode materials for Li-O2 battery. In addition, the unsaturated metals anchored on the surface with high density serve as active sites. A capacity of 9420 mA h g-1 with respect to the weight of MOF and carbon materials combined, was delivered in a Li-O2 cell based on Mn-MOF-74 under 1 atm of O2, four times as high as the value obtained in a cell without MOFs.
