  text: The SiOx anode exhibits a high specific capacity and commendable durability
    for lithium-ion batteries (LIBs). However, its practical application is hindered
    by significant volumetric fluctuations during lithiation/delithiation, alongside
    a metastable nature, which induces mechanical instability and irreversible lithium
    consumption, ultimately impairing long-term capacity retention in full-battery
    cell configurations. In this study, we present a phase-engineering approach designed
    to improve the structural stability of SiOx anodes for LIB applications. By incorporating
    lithium fluoride, amorphous SiOx undergoes partial transformation into a quartz-like
    phase, which enhances mechanical integrity and mitigates irreversible lithium
    loss. This modified anode demonstrates significantly improved stability and prolonged
    cycle lifespan. Through a combination of multiscale simulations and in situ characterizations,
    we elucidate the stabilization mechanisms conferred by the quartz phase, providing
    critical insights into the role of SiOx’s crystal structure in influencing degradation
    pathways. This work introduces an accessible and efficient method for controlling
    the crystallinity of SiOx, offering a practical solution to enhance the durability
    of high-energy-density LIBs.
