Review: Comparison of the LiBH4 Material Synthesis Method and its Application as a Hydrogen Energy Storage
Abstract
Nano-LiBH4is a promising material in technology development, especially as a storage materialof the alternative energies that has prospects in the future, i.e. hydrogen. The depleting fossil energy sources requires research and development of renewable energy to fulfil human energy needs on a large scale. This includes the used of methods and materials in storing this energy. This paper aims to review the researchresults of scientific studies on material sources, methods, and catalysts that can be used to obtain LiBH4nanomaterials with a high application rate, especially as a safe storage material for hydrogen energy. This review contains 15 papers from 1945 to 2019 consisting of several LiBH4 synthesis methods, i.e.ballmilling,chemical treatment, electrosynthesis, impregnation, andnano-confinement.The comparison results show that the best method for synthesizing LiBH4wasball milling because the process was simple and only requires a short time to obtain the nanoparticles. There are several goodmaterial sourcesfor LiBH4 synthesis,i.e. lithium, boron, Mg-Al waste, metaborate compounds, LiBD4, ZnCl2, LiH, LiBO2, Li3BO3catalyst,commercial LiBH4, and mesoporous carbon. Based on the comparison, the beststarting material was a mixture of commercial LiBH4 with mesoporous carbon which produces nano-LiBH4/Cmesoporous with a diameter of 5 nm.
