“…Thus, the present Li + transport mechanism of highly conductive Li 3 OX and "Li 3 OCl glass" needs to be confirmed. Moreover, the lithium oxyhalide SSEs with derived structures from antiperovskite, for example, layered antiperovskite Li 7 O 2 Br 3 , antispinel Li 3 OBr, 43 double antiperovskite Li 6 OSI 2 , 44,45 and low-dimensional networked antiperovskite 46 are all predicted with high ionic conductivity, and also need to be experimentally verified. Although the crystal structures of lithium halide hydroxides possess more Li vacancies than lithium oxyhalides, the Li + conductivity of the lithium halide hydroxide (10 À8 -10 À5 S cm À1 ) is generally lower than that of lithium oxyhalide (10 À6 -10 À2 S cm À1 ) due to the repulsive force of the frozen H hindered Li + transport.…”

Anti-perovskites X 3 BA, as the electrically inverted derivatives of perovskites ABX 3 , have attracted tremendous attention for their good performances in multiple disciplines, especially in energy storage batteries. The Li/Na-rich antiperovskite (LiRAP/NaRAP) solid-state electrolytes (SSEs) typically show high ionic conductivities and high chemical/electrochemical stability toward the Li-metal anode, illustrating their great potential for applications in the Limetal batteries (LMBs) using nonaqueous liquid electrolyte or all-solid-state electrolyte. The antiperovskites have been studied as artificial solid electrolyte interphase for Li-metal anode protection, film SSEs for thin-film batteries, and low melting temperature solid electrolyte enabling melt-infiltration for the manufacture of all-solid-state lithium batteries. Transition metal-doped LiRAPs as cathodes have demonstrated a high discharge specific capacity and good rate capability in the Li-ion batteries (LIBs). Additionally, the underlying scientific principles in antiperovskites with flexible structural features have also been extensively studied. In this review, we comprehensively summarize the development, structural design, ionic conductivity and ion transportation mechanism, chemical/electrochemical stability, and applications of some antiperovskite materials in energy storage batteries. The perspective for enhancing the performance of the antiperovskites is also provided as a guide for future development and applications in energy storage. K E Y W O R D S antiperovskite, chemical and electrochemical stability, energy storage, solid-state electrolyte Zhi Deng and Dixing Ni contributed equally to this work.

“…It was noted that serious particle boundary issues were experienced in cold‐processing their lithium ion counterparts (Li‐APs), due to their brittleness and thus poor deformability. Recently, some practical strategies, such as amorphization [53,54] or mixing/wetting with liquid organic electrolyte, [55] have been demonstrated to help reduce the boundary problems in anti‐perovskite Li‐APs.…”

All‐solid‐state sodium ion batteries (ASSIBs) have attracted great attention due to ever‐increasing safety concern about current lithium ion batteries and the limited natural reserves of lithium. A major materials basis to enable high‐performance ASSIBs lies in delivering ultra‐fast Na+ conductors, which is yet even more challenging than developing solid electrolytes for the lithium‐ion batteries. This is largely attributed to limited fundamental understanding of the transportation characteristics of sodium ions, which is rather different from the smaller alkali lithium ions. Here, we have carried out a perspective review of recent advances in theoretical formulation of novel solid electrolytes, focusing on methods, achievements, and the potential and shortcomings of identified materials systems. Efforts are made in offering a dependable framework to formulate fundamentally competitive materials to support developing “better” solid sodium‐ion batteries.

“…Using solid electrolyte to replace the flammable liquid electrolyte can largely relieve the thermal runaway risk of the conventional Li ion batteries (Janek and Zeier, 2016;Xia et al, 2019;Chen et al, 2020a;Gao et al, 2020). Currently, solidstate electrolytes (SSEs) include argyrodite (e.g., Li 6 PS 5 Cl) (Deiseroth et al, 2008), sulfides (e.g., Li 9.54 Si 1.74 P 1.44 S 11.7 Cl 0.3 ) (Kato et al, 2016;Xiao et al, 2021), LISICON (e.g., Li 2+x Zn 1-x GeO 4 ) (Adachi et al, 1996), NASICON (e.g., Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 ) (Deng et al, 2015), garnet (e.g., Li 7 La 3 Z r2 O 12 ) (Murugan et al, 2007;Huang et al, 2020;Huo et al, 2020), perovskite (e.g., Li 0.5 La 0.5 TiO 3 ) (Conductor et al, 2000), and Li rich anti-perovskite (LiRAP, e.g., Li 3 OCl 0.5 Br 0.5 ) (Zhao and Daemen, 2012;Emly et al, 2013;Li et al, 2016a;Hood et al, 2016;Zhu et al, 2016;Xu et al, 2019;Yin et al, 2020) have been widely investigated. Their Li ion conductivities are in the levels of 10 -6 ∼ 10 -2 S cm −1 with the activation energy being in the range of 0.2-0.6 eV.…”

Lithium-rich antiperovskites (LiRAPs) hold great promise to be the choice of solid-state electrolytes (SSEs) owing to their high ionic conductivity, low activation energy, and low cost. However, processing sheet-type solid-state Li metal batteries (SSLiB) with LiRAPs remains challenging due to the lack of robust techniques for battery processing. Herein, we propose a scalable slurry-based procedure to prepare a flexible composite electrolyte (CPE), in which LiRAP (e.g., Li2OHCl0.5Br0.5, LOCB) and nitrile butadiene rubber (NBR) serve as an active filler and as a polymer scaffold, respectively. The low-polar solvent helps to stabilize the LiRAP phase during slurry processing. It is found that the addition of LOCB into the NBR polymer enhances the Li ion conductivity for 2.3 times at 60°C and reduces the activation energy (max. 0.07 eV). The as-prepared LOCB/NBR CPE film exhibits an improved critical current of 0.4 mA cm−2 and can stably cycle for over 1000 h at 0.04 mA cm−2 under 60°C. In the SSLiB with the sheet-type configuration of LiFePO4(LFP)||LOCB/NBR CPE||Li, LFP exhibits a capacity of 137 mAh/g under 60 at 0.1°C. This work delivers an effective strategy for fabrication of LiRAP-based CPE film, advancing the LiRAP-family SSEs toward practical applications.
