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/C_mesoporous with a diameter of 5 nm.
