It combines the heavy alkali cation Rb+ with the flexible, weakly coordinating, highly fluorinated TFSI- anion.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMaximum Electrostatic Shielding\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e(Cs+): The Cs+ cation provides an effective Self-Healing Electrostatic Shield (SHES): The standard reduction potential of Cs+ (~ -2.92 V vs. SHE) is slightly less negative than that of Li+ (~ -3.04 V). During fast charging, electric fields concentrate at microscopic peaks\/dendrite tips on the lithium anode. Cs+ ions rapidly migrate to these high-field regions and accumulate without being reduced into metallic cesium. This accumulation forms a localized positive electrostatic buffer that repels incoming Li+ ions toward surrounding valleys, driving uniform, planar lithium electrodeposition across the anode surface.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSolid Electrolyte Interphase (SEI) Modification \u0026amp; Polysulfide Interaction\u003c\/strong\u003e: (1) \u003cem\u003eF-Rich \u0026amp; Inorganic Interphases\u003c\/em\u003e: The TFSI- anion decomposes at low potentials to build an inorganic-rich interphase (containing LiF, Li2S, and Li3N species), suppressing continuous solvent breakdown.
