“…The recent discovery of the lithium-rich antiperovskite compounds characterized by the general formula (Li 2 TM)ChO (with TM = Fe, Mn, Co; Ch = S, Se) has significantly broadened the landscape of potential cathode materials for lithium-ion batteries (LIBs) . This novel class of materials showcases highly favorable attributes in the context of lithium-ion battery application, including cost effectiveness, utilization of environmentally benign raw materials, efficient lithium diffusion, and the ability of multielectron storage per chemical unit. − From the so far investigated antiperovskite materials Li 2 FeSO, ,,− (Li 2 Co)SO, (Li 2 Mn)SO, (Li 2 Fe 1– x Mn x )SO, ,, (Li 2 Fe 0.9 Co 0.1 )SO, (Li 2 Co)SeO, (Li 2 Mn)SeO, (Li 2 Fe)S 1– x Se x O, and (Li 2 Fe)SeO, ,, the (Li 2 Fe)SO compound captivates with the highest theoretical capacity. Despite the promises of lithium-rich antiperovskites and especially (Li 2 Fe)SO, their great potential could not be fully exploited due to poor cycling stability (only 66% capacity retention in (Li 2 Fe)SO at 0.1 C after 50 cycles) …”

Lithium-rich antiperovskites promise to be a compelling class of high-capacity cathode materials due to the existence of both cationic and anionic redox activity. Little is however known about the effect of separating the electrochemical cationic process from the anionic process and the associated implications on the electrochemical performance. In this context, we report the electrochemical properties of the illustrative example of three different (Li 2 Fe)SO materials with a focus on separating cationic from anionic effects. With the high-voltage anionic process, an astonishing electrochemical capacity of around 400 mAh g −1 can initially be reached. Our results however identify the anionic process as the cause of poor cycling stability and demonstrate that the fading reported in previous literature is avoided by restricting to only the cationic processes. Following this path, our (Li 2 Fe)SO-BM500 shows strongly improved performance as indicated by constant electrochemical cycling over 100 cycles at a capacity of around 175 mAh g −1 at 1 C. Our approach also allows us to investigate the electrochemical performance of the bare antiperovskite phase excluding extrinsic activity from initial or cycling-induced impurity phases. Our results underscore that synthesis conditions are a critical determinant of electrochemical performance in lithium-rich antiperovskites, especially with regard to the amount of electrochemical secondary phases, while the particle size has not been found to be a crucial parameter. Overall, separating and understanding the effects of the cationic from the anionic redox activity in lithium-rich antiperovskites provides the route to further improve their performance in electrochemical energy storage.

Zinc‐air batteries are promising energy storage devices owing to their high energy density, low cost, and environmental friendliness. However, the development of durable and efficient bifunctional electrocatalysts is a major concern for Zn‐air batteries. In this review, we summarize the recent progress on transition metal dichalcogenides (TMDs) as bifunctional electrocatalysts for Zn‐air batteries. We discuss the advantages of TMDs, such as high activity, good stability, and tunable electronic structure, as well as the challenges, such as low conductivity, poor durability, and limited active sites. We also highlight the strategies for fine‐tuning the properties of TMDs, such as defect engineering, doping, hybridization, and structural engineering, to enhance their catalytic performance and stability. We provide a comprehensive and in‐depth analysis of the applications of TMDs in Zn‐air batteries, demonstrating their potential as low‐cost, abundant, and environmentally friendly alternatives to noble metal catalysts. We also suggest future directions like exploring new TMDs materials and compositions, developing novel synthesis and modification techniques, investigating the interfacial interactions and charge transfer processes, and integrating TMDs with other functional materials. This review aims to illuminate the path forward for the development of efficient and durable Zn‐air batteries, aligning with the broader objectives of sustainable energy solutions.
