AbstractThermal decomposition of LiPF6 and LiBC4O8 (lithium bis(oxalate)borate, abbreviated as LiBOB) were studied using TG (thermogravimetry)-DTG (derivative thermogravimetry) method with different heating rate beta of 5, 10, 20 and 40 degrees C min(-1) or at different constant temperature theta(C) (109.80, 118.79, 148.41, 176.86 degrees C for LiPF6 and 278.51, 298.13, 317.65, 336.13 for LiBOB). From the nonisothermal kinetics we calculate that n(LiPF6) is 1.01, n(LiBOB) is 1.04, EUPF6 is 91907.61 J/mol, and E-LiBOB is 205179.88 J/mol; from the isothermal kinetics we calculate that n for both LiPF6 and LiBOB are 1, E-LiPF6 is 91907.61 J/mol, E-LiBOB is 205179.88 J/mol, InA(LiPF6) is 16.89 s(-1), and InA(LiBOB) is 31.96 s(-1). The results obtained from the two ways have minor differences and can validate each other.
