Catalysis of 2-D conjugated polymers of metal-porphyrazine with sulfur bridges to the Li/SOCl_2 cell

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)]。相对于不含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。

The catalysis of 2-D conjugated polymers of metal-porphyrazine P （ MPzS8 ） [ M = Fe （ II ）, Co （ U ） and Zn （ II ） ] to lithium/thionyl chloride（ Li/SOC12 ）cell was studied. It was found that P（ MPzSs ）had high catalytic activity[ Fe（ II ） ≥ Co（ II ） 〉 Zn（ II ） ] to Li/SOC12 cell. When the cells contained O. 0150% P（ ZnPzSs ） ,P（ CoPzSs ） and P（ FePzSs ） were discharged at low tem- perature -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/cm^2 ,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.
