One of the main limitations for the implementation of hydrogen as energy carrier is the lack of an efficient and safe hydrogen storage system. Hydrogen storage in solid state through the formation of hydride compounds is a potential alternative to address this problem. In recent years, much effort has been devoted to improve the kinetic behavior of promising Li-Mg-B-H and Li-Mg-B-N-H destabilized hydride systems. In this work, nanosized additives added to 2LiBH4+MgH2 and 6Mg(NH2)2+9LiH+ LiBH4 are characterized via transmission electron microscopy (TEM). The aim is to understand the role of in situ formed nanostructured additives on the kinetic behavior of the investigated hydride systems. The information gained by TEM is helpful to optimize solid state hydrogen storage system for practical applications.
