## Description

- description: Inorganic solid electrolytes have emerged as promising candidates for
    realizing all-solid-state batteries because they eliminate flammable, low boilingpoint
    liquids in lithium-ion battery cells, improving safety and cycle life. In this
    study, we present a highly lattice-matched composite solid electrolyte consisting
    of an antiperovskite-perovskite system, offering the benefits of both antiperovskites
    as melt-infiltratable solid electrolytes and perovskites as fastion conductors.
    Atomistic simulations predict significant lithium-ion diffusion at the interface
    between cubic Li2OHCl and Li0.31La0.56TiO3. The incorporation of fluorine enables
    room-temperature operation by stabilizing the hightemperature cubic phase of Li2OHCl1-xFx
    and reduces the lattice mismatch ratio to 0.8% at the interface through lattice
    contractions. The composite solid electrolyte was synthesized via pressure-assisted
    melt infiltration. The solid electrolyte effectively infiltrates conventional
    lithium-ion battery electrodes while maintaining a stable interface structure.
    Electrochemical testing demonstrates promising charge-discharge characteristics,
    including long cycle life and rate performance. Intricate infiltration of the
    solid electrolyte into an electrode structure composed of active materialswithmicrocracks
    and high surface area enables stable operation by mitigating degradation phenomena
    typically observed in liquid electrolyte-based lithium-ion batteries.
