In this regard, polymeric protective layers are the commonest. On the one hand, the organic layer on the external side can ameliorate the poor contact between the inorganic SE and the electrode, protecting the inorganic SE and preventing the lithium dendrites from growing along the grain boundaries of the inorganic SE.
With the self-healing effect of electrolytes, the interfacial stability of the electrode-electrolyte can be effectively improved, and the growth of lithium dendrites arising from electrolyte damage can be prevented, thus realizing the protection of lithium metal anodes.
( Wiley-VCH Verlag GmbH & Co. KGaA ) A facile and effective strategy was developed to protect the lithium anode of a secondary lithium battery through fabrication of a protection film on the metal Li anode, in which a fluoroethylene carbonate (I) additive plays a key role in the crucial film-forming additive.
As a result, the existence of soluble lithium polysulfides in electrolyte substantially reduces the cycling life span of Li metal anode and therefore requires serious consideration for the protection of Li metal anode in Li–S batteries.
A protective layer on lithium metal is expected to reduce contact between lithium metal and the organic solvent, exert compressive mechanical force on the anode, and improve the selectivity and uniformity of lithium ion transport at the electrode surface. This review covers recent advancements in this topic.
