Description
Summary:Coordination complexes of Mg(BH 4 ) 2 are of interest for energy storage, ranging from hydrogen storage in BH 4 to electrochemical storage in Mg based batteries. Understanding the stability of these complexes is crucial since storage materials are expected to undergo multiple charging and discharging cycles. To do so, we examined the thermal stabilities of the 1 : 1 mixtures of Mg(BH 4 ) 2 with different glymes by DSC-TGA, TPD-MS and powder XRD analysis. Despite their structural similarities, these mixtures show diverse phase transitions, speciations and decomposition pathways as a function of linker length. Understanding speciation, stability, and degradation of Mg(BH 4 ) 2 ·glymes by powder XRD, DSC-TGA & TDS-MS.
