Highlights In this study Mn(BH 4) 2 was prepared by ball milling LiBH 4 + MnCl 2. DSC and TGA-MS showed that thermal decomposition started at 130 C and finished at 180 C with a total mass loss of a 8.5 wt.%. Concurrent desorption of hydrogen and diborane (approximately 9:1) was observed. The presence of excess LiBH 4 lowered the …
