Engineering Stable SEI Film on Mg-Doped Li Metal Anode by Electrolyte Additive With High Donor-Number Anion for Li-S Batteries

A more superior cycling stability and a higher utilization ratio of the Li metal anode have been achieved by additive- and nanostructure-stabilized SEI layers. A profound understanding of the composition, internal structure, and evolution of the SEI film sheds new light on dendrite-free high-efficiency lithium metal batteries.

The Stability

Polyvinyl alcohol (PVA) as a “glue” to cement the metal organic framework (Zn-MOF) sheet as a reasonable artificial SEI film. The artificial SEI film can efficiently adapt to the changes of the volume during the cycle, significantly improve the stability of the Li metal anode.
