Time-evolved NaFSI-modified LPSC interphases enable NaFSI-LPSC AFSSBs to retain 77.6% capacity after 500 cycles at 0.2 C, versus 32.1% after 100 cycles for bare LPSC.
- Why it matters: Parasitic reactions between freshly plated Li and sulfide solid electrolytes consume cathode-derived Li, raise interfacial impedance, and drive nonuniform Li plating/stripping, limiting practical anode-free operation.
- What they did: NaFSI was incorporated into Li 5.4 PS 4.4 Cl 1.6 (LPSC) and heat-treated to form an initially NaF/LiF-rich surface interphase that evolves over early cycles into a LiF/Li 3 N-rich outer layer with a buried NaF-containing phase.
- The result: The evolving Li 3 N-rich domains provide higher Li+ transport than NaF, which homogenizes interfacial Li+ flux, suppresses impedance growth and inactive Li buildup, and reduces filamentary shorting.
