Metal–Organic Frameworks as Cathode Materials for Li–O2 Batteries

Metal–organic frameworks (MOFs) with open metal sites enrich the population of O2 in the pores significantly and assist the Li–O2 reaction when employed as a cell electrode material. A primary capacity of 9420 mA h g−1 is achieved in a cell with Mn-MOF-74; more than four times higher than the value obtained in a cell without an MOF.
