“…It has been reported that coatings of Li-containing compounds with good Li-ion conductivity could induce good electrochemical performance for LIBs. As the LiAlO 2 phase can facilitate the hopping of lithium ions in the boundary region, it possesses good ability to conduct lithium ions. , Zhang et al demonstrated that LiAlO 2 coated on Na 2 Li 2 Ti 6 O 14 could provide fast charge transmission paths for lithium ions in LIBs . Thus, we envision that a LiAlO 2 coating can also be used to guard the deposition of lithium metal at the interface between lithium and Li 10 GeP 2 S 12 in ASSLMBs.…”

“…However, lithium dendrites are still growing during the cycle, and lithium alloy interface layers are not reversible, which cannot meet the application requirements of ASSLMBs. Therefore, it is urgent to find a stable coating with good ion conductivity that can effectively hinder the reduction of Li 10 25 Thus, we envision that a LiAlO 2 coating can also be used to guard the deposition of lithium metal at the interface between lithium and Li 10 GeP 2 S 12 in ASSLMBs.…”

Lithium (Li) metal has an ultrahigh specific capacity in theory with an extremely negative potential (versus hydrogen), receiving extensive attention as a negative electrode material in batteries. However, the formation of Li dendrites and unstable interfaces due to the direct Li metal reaction with solid sulfide-based electrolytes hinders the application of lithium metal in all-solid-state batteries. In this work, we report the successful fabrication of a LiAlO 2 interfacial layer on a Li/Li 10 GeP 2 S 12 interface through magnetic sputtering. As LiAlO 2 can be a good Li + ion conductor but an electronic insulator, the LiAlO 2 interface layer can effectively suppress Li dendrite growth and the severe interface reaction between Li and Li 10 GeP 2 S 12 . The Li@LiAlO 2 200 nm/Li 10 GeP 2 S 12 /Li@LiAlO 2 200 nm symmetric cell can remain stable for 3000 h at 0.1 mA cm −2 under 0.1 mAh cm −2 . Moreover, unlike the rapid capacity decay of a cell with a pristine lithium negative electrode, the Li@LiAlO 2 200 nm/Li 10 GeP 2 S 12 /LiCoO 2 @LiNbO 3 cell delivers a reversible capacity of 118 mAh g −1 and a high energy efficiency of 96.6% after 50 cycles. Even at 1.0 C, the cell with the Li@LiAlO 2 200 nm electrode can retain 95% of its initial capacity after 800 cycles.
