Solvation-derived amorphous motifs in lithium-metal SEI

Puntos clave

• The research aims to investigate the amorphous structures formed in the solid electrolyte interphase (SEI) on lithium metal.
• Analyzed the dominant structural components of the SEI using advanced characterization techniques.
• Focused on the solvation effects that contribute to the amorphous nature of the SEI.
• Compared amorphous versus crystalline phases in the SEI formation.
• Identified a significant fraction of the SEI as amorphous rather than crystalline.
• Demonstrated that solvation effects play a crucial role in the amorphous structure of the SEI.
• Highlighted implications for optimizing lithium metal batteries by leveraging amorphous motifs.
