Embodiment 1

[0040] The synthesis of conjugated nitrogen-containing aromatic fused ring polymer P-1 is as follows:

[0041]

[0042] 3,6-dibromo-9-(4-bromophenyl)carbazole, 5,10-dihydrophenazine, catalyst Pd(OAc) 2 , XPhos ligand and t-BuONa were added in proportion to anhydrous o-xylene for three freeze-pump-thaw cycles for degassing. The mixture was stirred at 120° C. for 48 hours under argon to carry out polymerization. After the reaction is completed, the mixture is filtered, washed and purified by Soxhlet extraction, and dried at high temperature under vacuum to obtain the conjugated aromatic condensed ring nitrogen-containing polymer P-1.

[0043] Mix 24mg P-1, 30mg KB and 6mg sodium carboxymethyl cellulose thoroughly, add 0.5ml deionized water, grind again to obtain a homogeneous slurry, evenly coat on aluminum foil, and then vacuum dry at 80°C for 12 Electrode film was prepared in hours. In a dry argon glove box, use the prepared electrode film as the positive electrode, glas...

The metal ion battery organic electrode material is a carbazole auto-polymer, a carbazole derivative auto-polymer, a carbazole and carbazole derivative auto-polymer, or a copolymer formed by copolymerization of carbazole and reduced phenazine, a copolymer formed by copolymerization of a carbazole derivative and reduced phenazine, or a copolymer formed by copolymerization of carbazole and tripolyindole, and a copolymer formed by copolymerization of a carbazole derivative and tripolyindole. The invention also provides a positive electrode containing the organic positive electrode material, a battery containing the positive electrode, and methods for preparing the positive electrode and the battery. The metal ion battery prepared from the material provided by the invention has relatively high capacity and energy density, good cycling stability and rate capability, and is expected to be used in a next generation of energy storage batteries with high energy density, environment friendliness and sustainability.

Description

technical field [0001] The invention belongs to the field of metal ion batteries, and more specifically relates to an organic electrode material for a metal ion battery, an electrode, a battery and a preparation method. Background technique [0002] Among existing electrical energy storage devices, batteries—particularly lithium-ion batteries—are one of the most efficient energy storage devices for integrating renewable energy. However, the increasing demand for human life and production, as well as the rapid development of portable electronic devices, electric vehicles, and large-scale energy storage, have further intensified the contradiction between the increasing demand for lithium-ion batteries and limited lithium resources. Therefore, Research and development of new energy storage devices and systems is imminent. [0003] Traditional inorganic cathode materials are limited by their theoretical capacity and structural stability, making it difficult to further increase ...
