Technical Field

Background
The super capacitor is used as a novel electrochemical energy storage device, is between a traditional capacitor and a rechargeable battery, has the advantages of high charging and discharging speed, simple preparation, environmental protection and the like, and becomes an energy device which is widely applied. The energy storage mechanism can be divided into an electric double layer capacitor and a pseudo capacitor, and the electric double layer capacitor and the pseudo capacitor respectively store charges through an electric double layer structure and a redox reaction.
The porous carbon material is a carbon material with different pore structures, has the characteristics of large specific surface area, heat and electricity conduction, high thermal stability and chemical stability and the like, and has important application in a super capacitor as an electrode material. However, the pores with different pore diameters have different effects on electrochemical transmission, so that the specific capacitance of most porous carbon materials is not ideal. It is reported in the literature that micropores, especially ultramicropores, contribute significantly better to electrochemical energy storage than other pores. The conjugated microporous polymer is used as a precursor, so that the porous carbon material with more micropores can be obtained, nitrogen atoms are easily introduced, the pseudo capacitance is increased, and the specific capacitance of the carbon material is favorably improved. However, most of the current conjugated microporous polymers are complex to synthesize, and large-scale synthesis is difficult to realize. For example, Jiang et al synthesized CMP-1 and CMP-1-NH2 using a Pd-catalyzed Sonogashira-Hagohara coupling method, and carbonized these two conjugated microporous polymers as precursors in an atmosphere of N2 or NH3 to obtain different porous carbon Materials (Journal of Materials Chemistry A,2016,4, 7665).

And after the reaction is finished, performing suction filtration, firstly stirring and washing for 24 hours at room temperature by using 1mol/L ammonia water, then washing for 24 hours at 60 ℃ by using deionized water and anhydrous methanol respectively, and after the suction filtration, placing in a vacuum oven at 60 ℃ for drying for 24 hours to obtain the pyridyl-containing conjugated microporous polymer. Then, heating the obtained pyridyl conjugated microporous polymer to 1000 ℃ at a heating rate of 5 ℃/min under an argon atmosphere for pyrolysis for 1h, and cooling to room temperature to obtain a pyridyl porous carbon material, namely a carbon material-1, wherein the BET specific surface area of the pyridyl conjugated microporous polymer is 1232m2/g。
The pore size distribution curve of the carbon material-1 obtained in this example at 77.4K by NLDFT is shown in fig. 2, and it is understood that the pore volumes are all contributed by pores having a pore diameter of 2nm or less, and there is substantially no significant fluctuation in pore volume at 2nm or more, which proves that the pores of the carbon material-1 are mainly micropores and a certain amount of ultramicropores exist.

The specific capacitances at current densities of 0.2, 0.5, 1, 2, 5, 10A/g were 262.2, 233.5, 212.7, 197.6, 177, 157.7F/g, respectively.

The carbon material-2 obtained in this example was in a three-electrode system and 0.5M H2SO4The GCD curve in the electrolyte is shown in FIG. 8, and the specific capacitance of the carbon material-2 is 324F/g under the current density of 0.1A/g, which is obviously superior to that of the common porous carbon material, so that the introduction of the pyridyl and the increase of the micropore volume are beneficial to improving the electrochemical energy storage of the carbon material. The specific capacitance at current densities of 0.2, 0.5, 1, 2, 5, 10A/g were 282, 239.5, 226, 212.6, 196, 182.4F/g, respectively.
