Abstract

The thermal desorption temperature T_d of single-cation borohydrides was found to decrease with increasing the value of the Pauling electronegativity χ_P of the cation (metal). We examined T _d of double-cation borohydrides ZrLi_n-4(BH ₄)_n, and then the correlation between T_d and χ_P determined for single-cation borohydrides is extended to double-cation ones. T_d for ZrLi_n-4(BH₄) _n with the composition n from 4 to 6 continuously increases from 440 K to 650 K, and approaches that of LiBH₄, 740 K: T_d correlates with the averaged χ_P calculated from n. The extended correlation might lead to precise adjustments in the thermodynamical stabilities of borohydrides.
