Here, we translate the concept of lubrication into an electrolyte-lubrication strategy for SSBs. We design a solvation-tailored electrolyte lubricant, termed ACE (aggregate cluster electrolyte), in which spatially structured ion-pair clusters direct interphase formation. In ACE, molecular-orbital reconfiguration within Li⁺–anion clusters favors the growth of a thin, electronically insulating, inorganic-rich solid–liquid electrolyte interphase (SLEI) on sulfide electrolytes, mitigating their intrinsic instability. The fluid ACE infiltrates interparticle voids, forming percolating Li⁺-conduction networks and facilitating dynamic reconstruction of the solid–electrolyte interphase during cycling. These attributes enable stable Li-metal cycling at reduced external pressure and enhance cathode active-material utilization. Electrochemical–thermal simulations further show that ACE homogenizes ionic fluxes and thermal gradients at the cell scale. Electrolyte lubrication thus emerges as a scalable interfacial-engineering approach for making sulfide-based SSBs operate under more practical conditions. 2026-09-12T00:00:00Z Dataset Media 10.1021/jacs.6c08623.s001 https://figshare.com/articles/media/Electrolyte_Lubricants_for_Solid-State_Batteries/33679771 CC BY-NC 4.0
