Enhanced Stability of Li-RHC Embedded in an Adaptive TPX™ Polymer Scaffold

In this work, the possibility of creating a polymer-based adaptive scaffold for improving the hydrogen storage properties of the system 2LiH+MgB₂+7.5(3TiCl₃·AlCl₃) was studied. Because of its chemical stability toward the hydrogen storage material, poly(4-methyl-1-pentene) or in-short TPX^TM was chosen as the candidate for the scaffolding structure. The composite system was obtained after ball milling of 2LiH+MgB₂+7.5(3TiCl₃·AlCl₃) and a solution of TPX^TM in cyclohexane. The investigations carried out over the span of ten hydrogenation/de-hydrogenation cycles indicate that the material containing TPX^TM possesses a higher degree of hydrogen storage stability.
