Thermal study on decomposition of LiBH4 at non-isothermal and non-equilibrium conditions

Thermal decomposition measurements for lithium borohydride (LiBH4) are performed at non-isothermal and non-equilibrium conditions by means of differential thermal analysis (DTA). A simplified alternative procedure is introduced for evaluating thermodynamic and kinetic parameters simultaneously using a single set of measurements. Rate constant (k) and enthalpy (??H = ???102.1 ± 0.7 kJ mol???1 LiBH4) are archived. Temperature dependence for activation energy (E a) is found taking advantage of Guggenheim???Arrhenius method; the mean activation energy is E?????????a 93.9 ± 0.9 kJ mol???1 LiBH4 in the range of heating rate ?? 1???50 K min???1.
