Key Points

To explore the mechanisms underlying lithium-mediated nitrogen reduction using operando techniques.
Utilized operando GI WAXS in a flow cell setup
Investigated hydrogen oxidation reactions
Analyzed the formation of solid electrolyte interphase (SEI) with diglyme electrolytes
Identified LiNH2 as the only stable crystalline intermediate during lithium-mediated nitrogen reduction
Revealed unique characteristics of the solid electrolyte interphase formed by diglyme electrolytes

Abstract

Operando GI WAXS in a flow cell with HOR revealed LiNH 2 as the only stable crystalline intermediate in the lithium mediated nitrogen reduction reaction (Li-NRR) and the unique solid electrolyte interphase (SEI) formed by diglyme electrolytes.
