Practical applications of Li-S batteries (LSBs) are inhibited by their poor electrical conductivity of electrode materials, greatly volumetric variation, as well as the polysulfide formation upon the cycling. To address these problems (MOFs)-based cathode materials, and easy morphology design have been extensively studied. An international team of researchers (Japan, China) has provided a comprehensive overview of MOFs-based sulfur host materials, their electrochemical reaction mechanisms, related evaluation parameters, and their performances used in LSBs in the past few years. The recent advances using in-situ characterization technologies for investigating the electrochemical reaction mechanism in LSBs are highlighted. They discussed the challenges and prospects associated with future research on MOF-related sulfur host materials. According to the researchers their overview may provide guidance for the identification of suitable MOFs-based sulfur cathode materials for high-performance LSBs for researchers… read more.
