Abstract
Solid-state light metal borohydrides represented by LiBH4, NaBH4, Mg(BH4)2, and Ca(BH4)2 with high hydrogen capacity are promising media to store and transport hydrogen safely and efficiently, raising a hope for popularizing electricity-hydrogen coupling systems built on clean and renewable energy. Yet stable thermodynamics and sluggish kinetics of light metal borohydrides remain two key issues to be addressed for achieving the rapid and reversible hydrogen desorption and absorption under mild conditions. In this review, the short introductions for basic hydrogen storage characteristics of light metal borohydrides and fundamental principles of common thermodynamic and kinetic modification strategies are first presented. Then the focus is on the research advances in reducing operation temperature, accelerating reaction rates, and enhancing cyclic reversibility of light metal borohydrides by using these strategies or their synergy. On this basis, the existing challenges and future directions on light metal borohydrides are proposed from novel and specific perspectives, aiming to obtain high performance hydrogen storage materials practically available towards electricity-hydrogen coupling systems.
期刊介绍:
The mission of Renewable and Sustainable Energy Reviews is to disseminate the most compelling and pertinent critical insights in renewable and sustainable energy, fostering collaboration among the research community, private sector, and policy and decision makers. The journal aims to exchange challenges, solutions, innovative concepts, and technologies, contributing to sustainable development, the transition to a low-carbon future, and the attainment of emissions targets outlined by the United Nations Framework Convention on Climate Change.
Renewable and Sustainable Energy Reviews publishes a diverse range of content, including review papers, original research, case studies, and analyses of new technologies, all featuring a substantial review component such as critique, comparison, or analysis. Introducing a distinctive paper type, Expert Insights, the journal presents commissioned mini-reviews authored by field leaders, addressing topics of significant interest. Case studies undergo consideration only if they showcase the work's applicability to other regions or contribute valuable insights to the broader field of renewable and sustainable energy. Notably, a bibliographic or literature review lacking critical analysis is deemed unsuitable for publication.
