Embodiment 1

[0034] First, 70 mL of N,N'-dimethylformamide (DMF) was added to a round-bottomed flask equipped with a condenser and a stirring device. Weighed 1,4,5,8-naphthalenetetracarboxylic anhydride (3mmol, 0.805g) and 3-amino-1,2,4-triazole (6mmol, 0.504g) were added to the previous DMF solution under nitrogen protection In the process, a suspension is obtained by stirring, and then the suspension is heated to 150°C in an oil bath under the protection of nitrogen or argon, and the reaction is carried out for 15h. The whole process requires continuous stirring and reflux. Finally, the oil bath was removed, and after the temperature of the solution dropped to room temperature, the product was precipitated through an ice bath, washed with water, and filtered to collect the gray-green solid product Compound A. 1 H NMR spectrum ( figure 1 ), 13 C nuclear magnetic spectrum ( figure 2 ),Infrared spectra( image 3 ) indicates that the synthesized product is A. Heat Gravity Map ( Figur...

Embodiment 2

[0036] The experimental method is the same as in Example 1, except that the 3-amino-1,2,4-triazole is changed to 4-amino-4H-1-2-4-triazole (6mmol, 0.504g) to obtain compound C .

Embodiment 3

[0038] The experimental method was the same as that of Example 1, except that 3-amino-1,2,4-triazole was changed to 2-aminoimidazole (6 mmol, 0.498 g) to obtain compound E.

Abstract

The invention relates to a polycarbonyl nitrogen heterocyclic organic compound for an electrode material of a lithium battery, and belongs to the field of preparation of lithium battery electrode materials. A preparation method of the polycarbonyl nitrogen heterocyclic organic compound comprises: dissolving an aromatic carboxylic acid anhydride and an amino nitrogen heterocyclic compound into a suitable organic solvent, reacting for a period of time under the protection of nitrogen or argon and at a reflux temperature, then cooling, filtering and washing to obtain a solid polycarbonyl nitrogenheterocyclic organic compound. The obtained polycarbonyl nitrogen heterocyclic organic compound has certain specific capacity and excellent cycle stability for preparing an electrode material of a lithium battery. The method has the advantages of simple process, low cost, low energy consumption, good reproducibility and excellent performance, and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of preparation of electrode materials for lithium batteries, in particular to a polycarbonyl nitrogen heterocyclic organic compound used as an organic positive electrode material for lithium batteries and a preparation method thereof. Background technique [0002] Under the continuous development of the economy, people will also face the huge challenge brought by the energy crisis. In such an environment, mankind will be more dependent on renewable energy in the future. Since most of these energy sources are affected by regional and intermittent nature, the search for new green energy storage and conversion devices has become a research hotspot. In the past ten years, new energy storage devices such as lithium batteries have developed rapidly. Among them, lithium batteries have the most development potential due to their large energy storage capacity, high development efficiency and low cost. However, the emerging ...
