Embodiment 1

[0034] First, 70 mL of N,N'-dimethylformamide (DMF) was added to a round bottom flask equipped with a condenser and a stirring device. Weigh 1,4,5,8-naphthalene tetracarboxylic anhydride (3mmol, 0.805g) and 3-amino-1,2,4-triazole (6mmol, 0.504g) into the previous DMF solution under nitrogen protection , the suspension was obtained by stirring, and then the suspension was heated to 150° C. in an oil bath under the protection of nitrogen or argon, and reacted for 15 hours. The whole process required 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 in 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 NMR spectrum ( figure 2 ),Infrared spectra( image 3 ) shows that the synthesized product is A. thermogravimetric map ( Figure 4 ) shows that this organic matter has high therma...

Embodiment 2

[0036] The experimental method is the same as in Example 1, except that 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 in 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 of a lithium battery electrode material, and belongs to the field of preparation of lithium battery electrode materials. The preparation method of polycarbonyl nitrogen heterocyclic organic compound is: dissolving aromatic carboxylic acid anhydride and amino nitrogen heterocyclic compound in a suitable organic solvent, reacting for a period of time under nitrogen or argon protection and reflux temperature, and then cooling down, Filter and wash to obtain a solid polycarbonyl nitrogen heterocyclic organic compound. The obtained multi-carbonyl nitrogen heterocyclic organic compound has a certain specific capacity and excellent cycle stability when used to prepare lithium battery electrode materials. The inventive 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 lithium battery electrode materials, in particular to a polycarbonyl nitrogen heterocyclic organic compound used as an organic positive electrode material of a lithium battery and a preparation method thereof. Background technique [0002] With the continuous development of the economy, people will also face the huge challenges brought about by the energy crisis. In such an environment, the future of mankind will be more dependent on renewable energy. Since most of these energy sources are affected by region and intermittency, seeking new green and environment-friendly 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 battery has the most development potential because of its large energy storage capacity, high development efficiency and low cost. However, the e...
