摘要：
Li(CH3CN)(4)PF6 and Li(C4H10O2)(2)PF6 complexes are important intermediates created in the synthetic process of high-purity LiPF6 electrolyte via transformation method. The thermal decomposition behavior of as-prepared Li(CH3CN)(4)PF6 and Li(C4H10O2)(2)PF6 crystals in pure nitrogen atmosphere has been studied by means of thermogravimetric-differential thermal analysis coupled with mass spectrometry (TG-DTA-MS). Results suggest that the decomposition of Li(CH3CN)(4)PF6 complex can be roughly divided into a three-stage process, and CH3CN is the primary gas product of decomposition process for Li(CH3CN)(4)PF6 in open Al2O3 pans. Further insight into Li(C4H10O2)(2)PF6 crystal indicates that it undergoes a similar decomposition process to Li(CH3CN)(4)PF6. Accordingly, the detailed deduction of the thermal decomposition mechanism formulas for them was presented in this paper. Besides, the thermal behaviors of Li(CH3CN)(4)PF6 and Li(C4H10O2)(2)PF6 complexes in hermetic aluminum pan were also investigated by differential scanning calorimetry (DSC).
