含硫桥的金属-四氮杂卟啉二维共轭聚合物对Li/SOCl2电池的催化作用

摘要

The catalysis of 2-D conjugated polymers of metal-porphyrazine P (MPzS8) [M =Fe (Ⅱ),Co (Ⅱ) and Zn (Ⅱ)] to lithittm/thionyl chloride(Li/SOCl2)cell was studied.It was found that P(MPzS8)had high catalytic activity[Fe(Ⅱ) ≥ Co(Ⅱ) ＞Zn(Ⅱ)] to Li/SOCl2 cell.When the cells contained 0.0150％ P(ZnPzS8),P(CoPzS8) and P(FePzS8) were discharged at low temperature-40 ± 2 ℃ and current density of 5 mA/cm2,the discharge time prolonged for about 20％,45％ and 55％,stable working voltage increased about 160 mV,200 mV and 300 mV;when discharged at room temperature 25 ± 5 ℃ and current density of 25 mA/cm2,the discharge time prolonged for about 8％,15％ and 15％,stable working voltage increased about 120 mV,160 mV and 180 mV,discharge voltage delay time shortened for 10 s,15 s and 15 s.%研究了金属-四氮杂卟啉二维共轭聚合物P(MPzS8)[M=Fe(Ⅱ)、Co(Ⅱ)和Zn(Ⅱ)]对锂/亚硫酰氯(Li/SOCl2)电池的催化作用,发现配合物具有较高的催化活性[Fe(Ⅱ)≥Co(Ⅱ)＞Zn(Ⅱ)].相对于不舍P(MPzS8)的电池,含有0.0150％ P(ZnPzS8)、P(CoPzS8)和P(FePzS8)的电池在低温-40±2℃下,以5 mA/cm2的电流密度放电,放电时间分别延长了约20％、45％和55％,稳定工作电压分别提高了约160 mV、200 mV和300 mV；在室温25±5℃下,以25 mA/cm2的电流密度放电下,放电时间分别延长了约8％、15％和15％,稳定工作电压分别提高了约120 mV、160 mV和180 mV,放电电压滞后时间分别缩短了10 s、15 s和15 s.
