Study and characterization of the effect of titanium-based compounds on the hydride system Li-B-Mg-H with high hydrogen storage capacity

One of the main constraints 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 hydride compounds formation is a potential alternative to address this problem. In this work, it is studied the effec...
