Lithium transport within the solid electrolyte interphase
Electrochemistry Communications, 2011 Abstract A LiClO4 SEI film grown on copper was examined with time-of-flight secondary ion mass spectrometry. The SEI porosity profile and Li+ transport processes within the SEI were studied with isotopically labeled 6LiBF4 electrolyte. An ~ 5 nm porous region, into which electrolytes can easily diffuse, was observed at the electrolyte/SEI interface ...

Solid–Electrolyte Interphase During Battery Cycling: Theory of Growth Regimes
ChemSusChem, 2020 AbstractThe capacity fade of modern lithium ion batteries is mainly caused by the formation and growth of the solid–electrolyte interphase (SEI). Numerous continuum models support its understanding and mitigation by studying SEI growth during battery storage. However, only a few electrochemical models discuss SEI growth during battery operation.

Zinc anode-compatible in-situ solid electrolyte interphase via cation solvation modulation
Nature Communications, 2019 Zinc chemistry is not favourable to the formation of a solid electrolyte interphase as a result of its high redox potential. In a break with the traditional wisdom, the present authors realise ZnF2-rich hybrid SEI on Zn anode via the modulation of ...
