Toward Realistic Full Cells with Protected Lithium‐Metal‐Anodes: the Effect of an Adaptive Self‐healing Artificial SEI (Adv. Energy Mater. 13/2025)

Solid Electrolyte Interphases

In article number 2403195, Witali Beichel, Ingo Krossing, and co-workers highlight the difference between the solid electrolyte interphases (SEIs), which can be attributed to applying an artificial LiBFEP-SEI by improving the Li ions' movement and suppressing the interphase's degradation at the lithium electrode. The depletion of Li ions is also visible due to the inferior properties of the natural SEI, illustrated by the accumulation of electrons at the electrode.
