  abstract     = {Lithium-metal oxides with a high formal Li2O content, such as Li5FeO4 (5Li2O•Fe2O3) and a Li2MnO3•LiFeO2 composite ({Li2O•MnO2}•{Li2O•Fe2O3}) have been explored as electrocatalysts for primary and rechargeable Li-O2 cells. Activation occurs predominantly by Li2O removal, either electrochemically or chemically by acid-treatment. Superior electrochemical behavior is obtained if activation occurs by acid-treatment; Li2MnO3•LiFeO2 catalysts provide 2516 mAh/g (carbon) corresponding to 931 mAh/g (electrocatalyst + carbon) during the initial discharge. The reaction is reasonably reversible during the early cycles. The approach has implications for designing electrocatalysts that participate through electrochemical Li2O extraction/reformation reactions, offering exceptionally high capacities.},

  abstract     = {The decomposition reaction of H2O2 aqueous solutions (H2O2 - H2O + 1/2O2) catalyzed by transition metal oxide powders has been compared with the charging voltage of nonaqueous Li-O2 cells containing the same catalyst. An inverse linear relationship between Ln k (rate constant for the H2O2 decomposition) and the charging voltage has been found, despite differences in media and possible mechanistic differences. The results suggest that the decomposition may be a reliable, useful, and fast screening tool for materials that promote the charging process of the Li-O2 battery and may ultimately give insight into the charging mechanism.},
