preparation example Construction

[0046] figure 1 It is a synthesizing schematic diagram of an organic electrode material of the embodiment of the present invention, such as figure 1 Shown, a kind of preparation method of organic electrode material comprises the following steps:

[0047] S1: Add an aprotic solvent to the container, place the container in an oil bath environment, pass inert gas, add a condensing device, and pass in circulating cooling water;

[0048] S2: adding an acid anhydride and an electrochemically active diamine to the aprotic solvent described in step S1 in sequence, and stirring at room temperature for 8-12 hours;

[0049] S3: The uniformly stirred mixture in S2 is gradually heated from room temperature to a certain temperature in the range of 200°C to 250°C, and kept at this temperature for 6 to 12 hours under reflux, then stop heating and cool to room temperature;

[0050] S4: The mixture obtained in step S3 is suction filtered, and washed with dimethylformamide ethanol, an aprotic ...

Embodiment 1

[0059] S1: Add 50mL quinoline into a 150mL three-necked flask, place the three-necked flask in an oil bath environment, pass nitrogen gas to add a condensing device and circulate cooling water.

[0060] S2: Add perylenetetracarboxylic dianhydride (PTCDA) and 2,6-diaminoanthraquinone (DDAQ) sequentially to the quinoline solution described in step S1, and stir at room temperature for 8 h.

[0061] The ratio of the amount of substances of PTCDA and DDAQ satisfies the following relationship:

[0062] n(PTCDA):n(DDAQ)=1:0.8

[0063] S3: The homogeneously stirred mixture in S2 was gradually heated from room temperature to 250° C., kept at this temperature and heated to reflux for 12 h, turned off the heating and cooled to room temperature.

[0064] S4: The mixture obtained in step S3 is suction-filtered, and repeatedly washed with ethanol, dimethylformamide (DMF), n-methylpyrrolidone (NMP) and deionized water until the filtrate is basically colorless, and the suction-filtered The ...

Abstract

The invention discloses an organic electrode material, which comprises an estolide part and a diamine part with electrochemical activity, wherein the estolide is one or several of pyromellitic dianhydride, naphthalenetetracarboxylic dianhydride or perylenetetracarboxylic dianhydride; the diamine is one or two of 2,6-diamino-anthraquinone, 1,4-diamino-2,3-dicyano anthraquinone; n(estolide):n(diamine) is 1 to (0.8 to 1.2). The invention also provides a preparation method of the organic electrode material. The invention also discloses a sodium ion battery with the organic electrode material. The organic electrode material provided by the invention has the advantages that the voltage of the material is improved; through increasing the electrochemical activity centers of the material, the volume of the material is increased; in addition, the preparation process of the material is simple; the sodium ion battery with the organic electrode material shows good electrochemical performance.

Description

technical field [0001] The invention belongs to the field of energy storage materials and technologies, and more specifically relates to an organic electrode material, a preparation method thereof, and an application thereof in an organic electrolyte. Background technique [0002] Information, energy and materials are called the three pillars of the new technological revolution. With the further development of human society, the economy is changing with each passing day, science and technology have made great breakthroughs, and the process of socialization has prompted people to increase their demand for energy. At present, primary energy is mainly used by human society, and the excessive use and abuse of non-renewable energy has exhausted the non-renewable energy, and a series of environmental pollution problems caused by this have seriously restricted the further development of society and science. The non-renewable and uneven distribution of traditional energy makes peop...
