Application and development of LiBH4 hydrogen storage materials

Hydrogen energy as a novel energy carrier holds promising prospects, and the storage and transportation technology of hydrogen energy is a focal point in current research on new energy sources. Among the many hydrogen storage materials, lithium borohydride has a good development prospect due to its high hydrogen storage capacity. This manuscript presents a thorough examination of the advantages and drawbacks associated with lithium borohydride as a hydrogen storage medium. It delineates the key methodologies involved in its synthesis, elucidates its crystal structure and decomposition kinetics, and underscores recent research endeavors aimed at enhancing the hydrogen storage capabilities of LiBH4 through strategies such as nano-confinement, composite material synthesis, catalyst incorporation, ion substitution, and other innovative techniques. Furthermore, it is suggested that employing multiple modification methods can enhance the hydrogen storage performance of LiBH4, although challenges such as reduced hydrogen storage capacity and decreased cycling performance should not be overlooked. This review offers valuable insights for the future development and application of LiBH4 as a hydrogen storage material. As the demand for hydrogen energy continues to grow, further research and enhancement of the performance of lithium borohydride will play a crucial role in advancing hydrogen energy technology.
