Lots of theoretical studies have predicted possible mechanical, magnetic, and catalytic properties of MBenes, which inspired their research in energy storage and conversion applications. However, a detailed review focusing on the synthesis of high-quality MBene nanosheets and their energy-related applications is not available. In this review, MBene with different structures and the latest developments in synthesizing high-quality MBene nanosheets from top-down exfoliation and down-top chemical vapor deposition are first summarized. Then, the basic properties of MBene are investigated, including mechanical properties, metallicity, and magnetism. Next, their key applications such as hydrogen production, ammonia production, and energy storage are elaborately discussed. Finally, the future perspectives and key challenges of MBenes's synthesis and applications are briefly provided.</p>","PeriodicalId":100919,"journal":{"name":"MetalMat","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/metm.12","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141967399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, as a retirement wave of more and more LIBs approaches, the disposed end-of-life batteries represent a growing hazard to ecosystem and human health. Recycling valuable metals from those spent LIBs still remain challenging because the current conventional metallurgical recycling processes involve the emission of toxic gas and waste chemicals as well as intensive energy consumption. These processes are not considered as green recycling approaches that contradict with the principles of carbon neutrality and circular economy embraced by the world. Hence, implementing green and sustainable recycling technologies of spent LIBs, especially for cathode materials, is an urgent need. This review provides a comprehensive understanding and critical evaluation of traditional pyrometallurgy, hydrometallurgy, and state-of-the-art direct recycling for recovering valuable metal materials from the spent LIB cathode. The fundamentals, methods, efficiencies, and feasibility of the three recycling approaches are also assessed. In addition, the recent progress for green innovation of hydrometallurgical and direct recycling processes as well as the potential research tendency for spent LIBs are discussed.</p>","PeriodicalId":100919,"journal":{"name":"MetalMat","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/metm.5","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136211838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
