摘要
The interfacial stability of lithium metal anodes dictated by solid electrolyte interphase (SEI) is essential for long-cycling high-energy-density lithium–sulfur batteries. Nevertheless, critical components of SEI for interfacial stabilization are particularly indistinct. Herein, the effect of various sulfur-containing components in SEI for stabilizing lithium metal anodes is disclosed in lithium–sulfur batteries. High-valence sulfur-containing species (Li2SO3 and Li2SO4) in SEI are conducive to uniform lithium deposition and stabilizing lithium metal anodes. In contrast, low-valence sulfur-containing species (Li2S and Li2S2) in SEI result in aggressive lithium dendrites and dead lithium. This work identifies the role of sulfur-containing components in SEI for stabilizing lithium metal anodes and provides rational design principles of SEI for protecting lithium metal anodes in practical lithium–sulfur batteries.
