Micro-emulsion electrolyte enables long-lifespan rechargeable batteries

In a recent Nature paper, Ji et al. introduced a micro-emulsion electrolyte that leverages interfacial tension to form robust LiF-rich electrolyte/electrode interphases simultaneously on both the anode and cathode, enabling long-life lithium metal batteries. This strategy bypasses traditional solvation design and offers a versatile, generalizable approach for next-generation rechargeable batteries.
