## Description

- description: We reveal a concept of adding K and Na to dual-cation systems and investigate
    their effects on dendrite growth morphology and electrolyte decomposition reactivity
    in lithium metal batteries (LMBs). We analyze the effects of Li/K- and Li/Na-alloyed
    surfaces on Li ion diffusion along the deposition direction, as well as the reactivity
    of the electrolytes and the composition of the solid electrolyte interface (SEI)
    resulting from electrolyte decomposition. Compared with the Li/K system, the Li/Na-alloyed
    surface can significantly reduce Li diffusion along the z-direction and effectively
    prevent the formation of dendrite-like morphologies. Furthermore, the Li/Na-alloyed
    surface substantially mitigates the reactivity of the bis(fluorosulfonyl)imide
    (FSI–) anion and fluorinated ether (TTE) solvent, thus inhibiting the generation
    of excessive SEI species. Additionally, the regulated and simplified components
    of a hybrid LiF/NaF SEI layer in the Li/Na system are observed. This hybrid layer
    is expected to promote the uniform deposition of Li and exhibit excellent electrical
    insulating properties, thereby effectively preventing electron transfer to the
    electrolytes and enhancing the Coulombic efficiency of LMBs. This study presents
    new insights into the dendrite-suppressing potential of alkali-metal alloys for
    improving the stability and safety of LMBs.
