## Description

- description: There is growing demand for practical implementation of lithium–oxygen
    batteries (LOBs) due to their superior potential for achieving higher energy density
    than that of conventional lithium-ion batteries. Although recent studies demonstrate
    the stable operation of 500 Wh kg−1-class LOBs, their cycle life remains fancy.
    For further improving the cycle performance of LOBs, the complicated chemical
    degradation mechanism in LOBs must be elucidated. In particular, the quantitative
    contribution of each cell component to degradation phenomenon in LOBs under lean-electrolyte
    and high-areal-capacity conditions should be clarified. In the present study,
    the mass balance of the positive-electrode reaction in a LOB under lean-electrolyte
    and high-areal-capacity conditions is quantitatively evaluated. The results reveal
    carbon electrode decomposition to be the critical factor that prevents the prolonged
    cycling of the LOB. Notably, the carbon electrode decomposition occur during charging
    at voltages higher than 3.8 V through the electrochemical decomposition of solid-state
    side products. The findings of this study highlight the significance of improving
    the stability of the carbon electrode and/or forming Li2O2, which can decompose
    at voltages lower than 3.8 V, to realize high-energy-density LOBs with long cycle
    life.
