Boric acid-destabilized lithium borohydride with a 5.6 wt% dehydrogenation capacity at moderate temperatures

Boric acid effectively promotes the dehydrogenation of lithium borohydride due to the interactions between protonic and hydridic hydrogen. The simple mixture of LiBH4-(4/3)B(OH)(3) can release 5.6 wt% hydrogen below 180 degrees C with only a trace amount of water, thus constituting a highly attractive single-use hydrogen storage material.
