Among renewable resources, biomass-derived materials have recently emerged as particularly promising candidates for semiconductor development, driven by progress in synthetic strategies. This review focuses on key synthetic approaches for producing semiconductors from biomass-derived materials, specifically tailored for sustainable energy systems.

Despite their potential, commercialization remains limited by key challenges such as the polysulfide shuttle effect, sulfur’s insulating nature, lithium metal anode instability, and thermal safety concerns. This review provides a comprehensive and forward-looking perspective on emerging material strategies—focusing on cathode, electrolyte, and anode engineering—to overcome these barriers. Special emphasis is placed on advanced sulfur–carbon composites, including three-dimensional graphene frameworks, metal–organic frameworks (MOFs), covalent organic frameworks (COFs), and MXene-based materials, which have demonstrated significant improvements in sulfur utilization, redox kinetics, and cycling stability. Innovations in electrolytes—particularly solid-state and gel polymer systems—are discussed for their roles in suppressing polysulfide dissolution and enhancing safety. The review also examines lithium metal anode protection strategies, such as artificial SEI layers, 3D lithium scaffolds, and lithium alloying. Finally, it discusses critical issues related to large-scale manufacturing, safety, and commercial scalability. With ongoing innovation in multifunctional materials and electrode design, Li–S batteries are well positioned to transform energy storage for electric vehicles, portable electronics, and grid-scale systems.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"13 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143866615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hydrogen was desorbed from Mg(BH4)2+30HEH@Ti3C2 at 83.5 °C, with a complete hydrogen release of 9.84 wt% achieved at 330 °C. The dehydrogenation activation energies were notably reduced to 131 kJ/mol and 163 kJ/mol, which were identified as the primary factors responsible for the enhanced dehydrogenation kinetics. Cyclic tests revealed that the HEH@Ti3C2 significantly enhanced the reversible ability of Mg(BH4)2, maintaining a reversibility of 4.6 wt% after 10th test.
