Metal–organic framework (MOF) electrocatalysts have emerged as good platforms for catalyzing SRR and SER, but their catalytic performance is challenged by poor electrical conductivity and limited chemical stability. Functionalized MOFs and their hybrids may be beneficial for stabilizing and improving the desired catalytic properties to achieve high-performance LSBs. This review provides a detailed overview of engineering principles for improving the activity, selectivity, and stability of MOF-related electrocatalysts via composition modulation and nanostructure design as well as hybrid assembly. It presents and discusses the various advances achieved by using in situ characterization techniques, simulations, and theoretical calculations to reveal the dynamic evolution of MOF-related electrocatalysts, enabling an in-depth understanding of the catalysis mechanism at the molecular/atomic level. Lastly, prospects and possible research directions for MOF-related sulfur electrocatalysts are proposed.</p></div>","PeriodicalId":100489,"journal":{"name":"eScience","volume":"3 5","pages":"Article 100107"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50204056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To overcome these shortcomings and reduce the reliance on lithium, electrode materials used for these post-lithium batteries must be improved. Pre-intercalation of foreign species into the lattice of promising electrode materials can enhance their electrochemical performance in comparison to the un-pre-intercalated counterparts, closing the performance gap with lithium-ion batteries.

Current Li-ion batteries suffer a major loss of capacity and power and fail to operate normally when the temperature decreases to −20 ​°C. This deterioration is mainly attributed to poor Li-ion transport in a bulk carbonated ester electrolyte and its derived solid–electrolyte interphase (SEI).
