  text: 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.

  text: 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.
