The Synthesis Of Phthalocyanine Complexes And Their Catalytic Activity Of The Lithium / Thionyl Chloride Battery

In this thesis, twenty-two phthalocyanine compounds which fall into four categories were designed and prepared. Besides, we discussed the effects of different series and different metals to the discharge characteristic of Li/SOCl2 battery.Among these phthalocyanine compounds, chloride single-core and double-core metal phthalocyanines which include homonuclear and heteronuclear compounds were prepared by solide-phase melting method, and a-(QO)4PcZn was prepared in solvent. All of the compounds were characterized by Element Analyse, FT-IR, UV-vis and some of them were also characterized dy TGA.The catalytic activity of all these prepared compounds were evaluated by electrical property test for Li/SOCl2 battery. Besides, some cyclic voltammetry experiments were completed to study the property of the catalystic reaction. As shown in the result, The different substitute group, the amount of substitute group and the conjugated circumstance all will effect the catalytic activity.The SEM analyse were finished to study the morphology of carbon membrane, the result shown that the carbon membrane were loosen by phthalocyanine compounds, which could increase the discharge voltage of Li/SOCl2 battery. The catalytic mechanism of Li/SOCl2 battery was also investigated. Phthalocyanine compounds will act as efficient active catalyst when they have enough active sites and all these active sites reach a proper state by synergistic effect.Besides, we designed a lot of experiments to obtain the crystal of the phthalocyanine compounds, which could study the accurate molecular structures of the catalysts.
