Atomic-scale mechanism of alloy anodes mitigating polysulfide-induced degradation in lithium–sulfur batteries

Key Points

• Mitigates polysulfide-induced degradation effectively in lithium–sulfur batteries, enhancing performance and lifespan.
• Key evidence shows that the chemically integrated solid electrolyte interphase (SEI) significantly improves battery function.
• The findings stem from atomic-scale mechanisms observed within various alloy systems, including Li–Mg, Li–Al, and Li–Zn.
• These insights may enable advances in lithium–sulfur battery technology, addressing current limitations and improving energy density.
