Summary

Computation and atomic-layer deposition identified magnesium oxide as a promising interface layer.

Argonne researchers tested ultrathin coatings on a sulfide solid electrolyte. Magnesium oxide improved interfacial stability; predicted-stable zirconium oxide performed poorly because reaction products impeded lithium. The method speeds comparison but does not deliver a complete long-life solid-state cell.

Why it matters

Computation and atomic-layer deposition identified magnesium oxide as a promising interface layer.
