“…Nikodimos et al investigated the effect of ethylene carbonate‐based reduction‐resistant LE (RRLE) as an anolyte and acetonitrile‐based oxidation‐resistant LE (ORLE) as catholyte that were designed for SSBs. [ 108 ] Figure 5e shows that after the Li‐LAMGP interface is infiltrated using 5 μL of the RRLE, and the interfacial impedance is highly reduced from 1.06 kΩ of the Li | LAMGP | Li cell to 7.8 Ω of the Li | RRLE | LAMGP | RRLE | Li cell. [ 108 ] The RRLE anolyte and ORLE catholyte keep a consistent Li‐ion migration across the interface between the LAMGP SSE and the electrodes, thus prevent Li dendrite formation and remarkably improve the uniformity and robustness of the interfaces.…”

Halide Solid‐State Electrolytes: Stability and Application for High Voltage All‐Solid‐State Li Batteries

“…[12] Several attempts have been undertaken in recent decades to build solid electrolytes with good Li + conductivity, such as polymer solid electrolytes, [13][14][15][16][17][18] sulfide solid electrolytes, [19][20][21] oxide solid electrolytes, [22][23][24][25][26][27][28] anti-perovskites, [29][30][31] and lithium phosphorous oxynitrides. [32][33][34][35][36] Oxide-based solid electrolytes, such as garnet and NASICON-type, have good chemical stability with cathode materials but are brittle and have a poor contact surface with the cathode, [37] and we may need to use a liquid electrolyte to improve interface wettability. [37][38][39][40] Considering their high Li + conductivity and ductility sulfide solid electrolytes have been extensively explored among the numerous types of solid electrolytes.…”

[41][42][43][44][45] Li 10 GeP 2 S 12 (LGPS), for example, has a high ionic conductivity of more than 10 mS cm −1 , which is almost equivalent to those of the conventional liquid electrolytes.…”
