Thermal stability and structural studies on the mixtures of Mg(BH4)2 and glymes
Abstract
Coordination complexes of Mg(BH4)2 are of interest for energy storage, ranging from hydrogen storage in BH4 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(BH4)2 with different glymes by DSC-TGA, TPD-MS and powder XRD analysis. Despite their structural similarites, these mixtures show diverse phase transitions, speciations and decomposition pathways as a function of linker lengthPublished: May 27, 2022
