Abstract: Three types of next generation batteries are currently being envisaged among the international community: metal-air batteries, multivalent cation batteries and all-solid-state batteries. These battery designs require high-performance, safe and cost effective electrolytes that are compatible with optimized electrode materials. Solid electrolytes have not yet been extensively employed in commercial batteries as they suffer from poor ionic conduction at acceptable temperatures and insufficient stability with resp… Show more

“…In these nitride systems with only nonmetal elements, passivating interphase would form at the Li metal interface regardless of x N (Figure ). Similarly, using only these nonmetal elements also leads to Li‐passivating interphases in oxides and sulfides, as observed in LiPON, Li 3 OCl/Li 3 OBr, Li 9 S 3 N, Li 7 P 3 S 11 , and Li 7 P 2 S 8 I solid electrolytes, which are Li metal compatible …”

“…The thermodynamically favorable Li reduction of metal cations would lead to the formation of MIEC interphase and continuous decomposition of bulk materials, resulting in poor stability against Li metal. To avoid the detrimental effects of metal cations on stability, using only nonmetal elements, such as P, Cl, Br, I, instead forms passivating interphase and enables stability against Li metal, as demonstrated in some Li‐compatible solid electrolytes, such as LiPON, Li 3 OCl/Li 3 OBr, Li 9 S 3 N, Li 7 P 3 S 11 , and Li 7 P 2 S 8 I . However, there is a limited choice of these compounds for stabilizing Li metal.…”

“…In conclusion, while both EC3 and EC4 can be effective in Au|SSE|Au cells, only EC4 is suitable for Li|SSE|Li cells. [17] Figure S4A (Supporting Information) shows that from 40 to 110 °C there are no significant changes in conductivities within three heating/cooling cycles. The equivalent circuit EC4 consists of two resistances (which are assumed to represent bulk resistance of a solid electrolyte (R1) and interfacial resistance (R2)), and interfacial, electrode, and geometrical constant phase elements.…”

“…We have conducted multiple heating/cooling experiments (cycles) in order to reveal the cycle-dependent conductivities, as it was reported previously. [17] Figure S4A (Supporting Information) shows that from 40 to 110 °C there are no significant changes in conductivities within three heating/cooling cycles. We have noticed a slight increase in conductivities of Li 2 OHCl at 26 °C after two heating cycles ( Figure S4B, Supporting Information), probably due to reduced contact resistance between Li 2 OHCl and Li.…”

“…In recent years, antiperovskites received special attention due to their unique physical properties such as magnetism and ionic conductivity [2][3][4][5][6][7][8]. Krivovichev [9] reviewed antiperovskite-type structures in minerals built upon O-and F-centered octahedra, which demonstrated polytypic variety of this kind of materials.…”
