摘要：

Enthalpy of formation of lithium hexafluorophosphate was calculated based on the differential scanning calorimetry study of heat capacity and thermal decomposition. It was found that thermal decomposition of LiPF6 proceeds at normal pressure in the temperature range 450-550 K. Enthalpy of LiPF6 decomposition is Delta(d)H(LiPF6, c, 298.15 K)= 84.27 +/- 1.34 kJ mole(-1). Enthalpy of formation of lithium hexafluorophosphate from elements in standard state is Delta(f)H(0)(LiPF6, c, 298.15 K) = -2296 +/- 3 kJ mol(-1).
