| Summary: | 碩士 === 國立臺灣科技大學 === 應用科技研究所 === 105 === In this study, benzimidazole as the main body of the structure to research different functional groups as the electrolyte solution of lithium salt. The results were tested by electrochemical quartz crystal microbalance to investigate benzimidazole lithium salt additives in different electrodes electrochemical reaction kinetics and the formation mechanism of Solid Electrolyte Interface (SEI). The chemical composition of solid electrolyte interface film was identified by nuclear magnetic resonance spectroscopy.
The results showed the addition of benzimidazole lithium salt did affect the EC reduction potential, especially in LiBZ and LiMB, not only in the results of the gold electrode but also the results of the graphite electrode showed the effects of the early reduction reaction. The reaction of kinetics changed significantly as well. In addition, LiTFB contains (-CF3) substituents improved the electron density of LiTFB. In the previous research and in-situ EQCM proved that the LiTFB and carbonates would produce novel forms of solid electrolytes.
