Problems solved by technology

Among many cathode materials for lithium batteries, inorganic transition metal oxides are the current research hotspots. However, this type of cathode materials has the following disadvantages when used in future power sources: First, the theoretical specific capacity is low, and LiCoO 2 , LiNiO 2 , LiMn 2 o 4 、LiFePO 4 The theoretical specific capacity of such materials is below 300mA h / g, and the actual available specific capacity does not exceed 170mAh / g, so the room for improvement is very limited; secondly, the reserves of raw materials in nature are limited, and some materials have the problem of heavy metal elements polluting the environment. They need to consume a lot of energy, which does not meet the requirements of low-carbon economy and sustainable development; third, there are still hidden dangers in safety. When the battery is overcharged, it is easy to produce high-valence metal oxides, and with the release of oxygen, violent explosions occur. Exothermic reaction

example 1

[0018] Dissolve ADDAQ (500mg, 1.95mmol) in 40ml of ethyl acetate, add 3 equivalents of anhydrous ferric chloride (1.03g), stir at room temperature for 6h, point samples for analysis of no raw material points, add a large amount of distilled water, filter, and wash with alcohol A tan product was obtained in about 80% yield.

example 2

[0020] At room temperature (25°C), dissolve ADDAQ (500mg, 1.95mmol) in 50ml of acetic acid, cool down to 0°C, and slowly add (NH 4 ) 2 S 2 o 8 (1.2g, 5.26mmol) of saturated aqueous solution 5ml, stirred in an ice bath for 4h, sampled and analyzed without raw material points, then added a large amount of distilled water, stirred and left standing overnight, filtered and washed to obtain a reddish-brown powdery product, the yield was about 85% %.

example 3

[0022] The concentrated sulfuric acid of 2.17ml 98% is slowly added dropwise in DMF, configures 40ml DMF sulfuric acid solution, sulfuric acid concentration is 1mol / L, the ADDAQ of 2mmol is added in 30ml DMF sulfuric acid solution, then its ultrasonic dispersion 15min, impels single 200mg (2mmol) of chromium trioxide was dissolved in 10ml of DMF sulfuric acid solution, and the oxidant was added dropwise to the continuously stirring monomer solution, and the reaction was carried out at room temperature (20°C) for 24h. The reacted solution was suction filtered, and then the product was washed with DMF to obtain a brown product with a yield of about 78%.

[0023] According to the nuclear magnetic spectrum ( figure 1 ), ADDAQ 1 H-NMR shows that δ=14.104 and 13.640 correspond to the two hydrogen atoms on the hydroxyl group respectively, δ=6.955 corresponds to the two hydrogen atoms on the amino group, and δ=7.545~7.366 correspond to the 6, 7 and 8 carbons on the ring respectively ...

Abstract

The invention relates to a preparation method of a novel aminoanthraquinone polymer having a structural formula shown in the specification. A quinone compound is prepared by a one-step reaction of 5-amino-2,3-dihydro-1,4-dyhydroxy anthraquinone (ADDAQ) as a raw material and an oxidizing agent in a solvent. The compound can be used for positive pole materials of high specific capacity lithium batteries, and can also be used for optoelectronic device materials, dyeing agents and the like. The preparation method is simple and easy, a pure product can be obtained without purification, and the yield is more than 80%.

Description

technical field [0001] The invention relates to a novel quinone polymer and a preparation method thereof. The polymer can be used as positive electrode material of high-capacity lithium battery, as well as photoelectric device material and dyeing agent. Background technique [0002] Energy is an important resource for national economic and social development. The widespread use of coal and petroleum does not meet the requirements of a low-carbon economy, and non-renewable resources such as petrochemical energy are decreasing day by day, which is unsustainable. Therefore, the development and rational use of renewable energy has become a major project related to the national economy and people's livelihood. Due to its high specific energy and long cycle life, lithium secondary batteries have become one of the keys to the utilization of renewable energy in the future. Among many cathode materials for lithium batteries, inorganic transition metal oxides are the current researc...
