| Li/SOCl2 battery is a chemical power source with several excellent characteristics,such as high specific energy,high voltage,long storage life and a wide range of operating tempera-ture,which has been widely applied in various fields.However,this battery also has disad-vantages like voltage hysteresis and safety performance.Firstly,in this paper,nitrobenzene using as a solvent and the 4-Nitrophthalimide and 3-Nitrophthalic acid as precursors,2,9,16,23-Tetranitro-metal-phthalocyanine(Cu2+,Co2+,Ni2+,Zn2+,Fe2+,Mn2+)and 1,8,15,22-Tetranitro-metal-phthalocyanine were synthesed,and then reduced with Sodium sulfide nonahydrate and change into Tetraami-no-zinc-phthalocyanine.finally,Multi-walled carbon nanotubes chemically modified by 2,9,16,23-tetraaminophthalocyanine-cobalt and 1,8,15,22-tetraamino-phthalocyanine-cobalt with secondary amines bond.Their structures have been prepared and characterized by ATR-FTIR spectra,UV-Vis,SEM,XPS,X-RAY powder diffraction and X-ray photoelectron spectroscopy analysis spectra.According to discharge test and cyclic voltammetry,the catalysts have enhanced the per-formance of Li/SOCl2 battery.Experiment results show that:a.The voltage and capacity can be effectively increased by 8.86%and 89.2%by using 2,9,16,23-TAPcCo as catalysts;And 9.72%,93.3%by useing 1,8,15,22-TAPcCo as catalysts;And 10.1%,97.5%by using Chemical Modification of Multi-Walled Carbon Nanotubes by 2,9,16,23-Tetraamino-phthalocyanine-Cobalt as catalysts;And 10.5%,103.3%by using Chemical Modification of Multi-Walled Carbon Nanotubes by 1,8,15,22-Tetraamino-phthalocyanine-Cobalt.b.the catalyst has good catalytic behavior at room temperature,but it still changes little,although it has different substituent positions. |
