Destabilization of LiBH4 by (Ce, La)(Cl, F)3 for hydrogen storage

▶ Ce(BH4)3 and La(BH4)3 were obtained by ball milling LiBH4 + 1/3(Ce, La)Cl3 mixtures. ▶ The dehydrogenation temperatures of ball milled LiBH4 + 1/3(Ce, La)(Cl, F)3 were decreased to 220-320 °C.▶ Partial reversibility was achieved for LiBH4 + 1/3(Ce, La)(Cl, F)3.
