Embodiment 1
[0029] In a 100mL three-necked flask, 60mL of acetic acid was added, while 2,3-diamino-1,4-dimethoxybenzene (0.756g, 4.5mmol), cyclohexanone decahydrate (0.522g, 1.5mmol) were added , under the protection of nitrogen, the reaction mixture was continuously stirred in the reflux state. The reaction time was 48 hours. After the reaction, stop heating, add water to precipitate the brown solid product, collect the solid by suction filtration, wash with water and ethanol for several times, and vacuum at 80 ° C. After drying for 6h, Compound A: 1,4,7,10,13,16-hexamethoxydiquinoxaline phenazine was obtained. figure 1 is the infrared spectrum, figure 2 is the H NMR spectrum, image 3 is the carbon NMR spectrum, Figure 4 for the massspectrogram.

Abstract
The invention relates to a diquinoxaline phenazine derivative and a synthesis method and application thereof and belongs to the field of synthesis of electrode materials for lithiumion batteries. Thesynthesis method comprises that a 2, 3-diamino-1, 4-phenyl derivative and cyclohexanone decahydrate are added into a reactor in an inert protective atmosphere and are dissolved in an organic solvent,the reaction mixture is continuously stirred in a reflux state for 6-48h, after the reaction, heating is stopped, and water is added into the reaction system so that solid products are precipitated.The diquinoxaline phenazine derivative has a broad application prospect in the field of lithiumionbattery electrode materials.
Description
technical field [0001] The invention belongs to the field of synthesis of lithiumionbattery electrode materials, in particular to bisquinoxaline phenazine derivatives and their synthesis methods and applications. Background technique [0002] With the increasing demand for large-scale battery systems from electric vehicles (EV) and smart renewable energies, the prospect of using organic materials as electrodes for rechargeable batteries is becoming increasingly attractive. In recent years, the research and application development involving positive and negative electrode materials and functional electrolytes of lithium-ion batteries at home and abroad are quite active. The purpose is to develop low-cost, high-safety, high-capacity, high-power, long-life, and environmentally friendly lithium-ion batteries . [0003] Currently, based on embedded metal oxides (such as LiCoO 2 , LiMn 2 o 4 、LiFePO 4 etc.) The specific energy of the lithium-ion battery of the cathode mater...
