## Description

- description: The operation of lithium-oxygen (Li-O2) batteries under lean electrolyte
    conditions offers higher energy density but leads to rapid degradation and short
    cycle life. Although cathode passivation and electrolyte decomposition occur in
    all regimes, we show that under lean electrolyte conditions, failure is primarily
    driven by progressive electrolyte consumption at the lithium/solid electrolyte
    interphase (SEI), rather than by irreversible cathode passivation. Poor wetting
    of the lithium surface results in heterogeneous SEI growth and high local current
    densities, which accelerate electrolyte loss and cell failure. Strategies aimed
    at improving interfacial stability, including optimized wetting and SEI forming
    additives, significantly extend cycle life without compromising energy density.
    Our results establish anode-electrolyte interactions as the dominant degradation
    mechanism under lean electrolyte conditions, and emphasize the need to engineer
    a stable Li/SEI interface for long-lasting Li-O2 batteries.
