“…The compound, Li 4 P 2 S 6 , have been reported to exhibit considerable ionic conductivity and good interface stability towards lithium metal [27][28][29][30], making it desirable for interface protection for Li 10 GeP 2 S 12 . Besides, both LiH 2 PO 4 and Li 3 PO 4 have been proven to be efficient protective layers for Li/solid electrolyte interface [16,[31][32][33][34], indicating phosphide, such as Li 2 HPO 3 , can stabilize the Li/Li 10 GeP 2 S 12 interface. Figures S3 and S4 presents the surface and cross-section morphology of Li 10 GeP 2 S 12 pellets before and after air exposure, showing the obvious decomposition layer coated on the surface of Li 10 GeP 2 S 12 pellet.…”

Moist air is a great challenge for manufacturing sulfide-based all-slid-state lithium batteries as the water in air will lead to severe decomposition of sulfide electrolytes and release H2S gas. However, different with direct reaction with water, short-period air exposure of Li10GeP2S12 sulfide electrolyte with controlled humidity can greatly enhance the stability of Li10GeP2S12 against lithium metal, thus realizing stable Li10GeP2S12 based all-solid-state lithium metal batteries. During air exposure, partial hydrolysis reaction occurs on the surface of Li10GeP2S12 pellets, rapidly generating a protective decomposition layer of Li4P2S6, GeS2 and Li2HPO3 in dozens of seconds. This ionically conductive but electronically insulation protecting layer can effectively prevent the severe interface reaction between Li10GeP2S12 and lithium metal during electrochemical cycling. The Li/40 s-air-exposed Li10GeP2S12/Li cell shows long cycling stability for 1000 h. And the LiCoO2/40 s-air-exposed Li10GeP2S12/Li batteries present good rate capability and long cyclic performances, showing capacity retention of 80% after 100 cycles.

“…142 Thus, there might be a gradual evolution process for these coating layers and this process might have limited their lifetime. Besides the oxide coatings, three Li-containing coatings, namely, LiF, 143 Li 3 PO 4 , 144 and LAS 124 were studied to date. LiF is the main component of an SEI layer in LIBs.…”

“…Li 3 PO 4 has demonstrated a high elastic modulus and ionic conductivity in previous reports [ 105 ]. In 2021, Niu et al [ 91 ] deposited amorphous Li 3 PO 4 onto Li metal using lithium tert-butoxide and trimethyl phosphate (TMP). The resulting Li 3 PO 4 coating can effectively suppress the growth of needle-like lithium dendrites and reduce side reactions between Li metal and electrolytes.…”

Atomic and Molecular Layer Deposition as Surface Engineering Techniques for Emerging Alkali Metal Rechargeable Batteries

Alkali metals (lithium, sodium, and potassium) are promising as anodes in emerging rechargeable batteries, ascribed to their high capacity or abundance. Two commonly experienced issues, however, have hindered them from commercialization: the dendritic growth of alkali metals during plating and the formation of solid electrolyte interphase due to contact with liquid electrolytes. Many technical strategies have been developed for addressing these two issues in the past decades. Among them, atomic and molecular layer deposition (ALD and MLD) have been drawing more and more efforts, owing to a series of their unique capabilities. ALD and MLD enable a variety of inorganic, organic, and even inorganic-organic hybrid materials, featuring accurate nanoscale controllability, low process temperature, and extremely uniform and conformal coverage. Consequently, ALD and MLD have paved a novel route for tackling the issues of alkali metal anodes. In this review, we have made a thorough survey on surface coatings via ALD and MLD, and comparatively analyzed their effects on improving the safety and stability of alkali metal anodes. We expect that this article will help boost more efforts in exploring advanced surface coatings via ALD and MLD to successfully mitigate the issues of alkali metal anodes.
