Solid organic electrocatalysts have hardly been tested in Li-O-2 batteries. Here, a new solid organic electrocatalyst, dilithium quinone-1,4-dicarboxylate (Li2C8H2O6) is presented, which is expected to overcome the shortcomings of inorganic catalysts. The function-oriented synthesis is low cost and low polluting. The electrocatalytic performance is evaluated by following the degradation of Li2O2 during the charge process in a Li-O-2 cell through insitu XRD and operando synchrotron radiation powder XRD (SR-PXD) measurements. The results indicate that the electrocatalytic activity of Li2C8H2O6 is similar to that of commercial Pt. The Li2O2 decomposition in a cell with Li2C8H2O6 catalyst follows a pseudo-zero-order reaction, virtually without any side reactions. These results provide an insight into the development of new organic catalysts for the oxygen evolution reaction (OER) in Li-O-2 batteries.
