High-conductivity carbon material and preparation method thereof

Abstract

The invention discloses a carbon material and a preparation method thereof. The preparation method comprises the following steps: adding a compound containing at least three alkynyl as well as a catalyst into a solvent, and reacting at a certain temperature, so as to obtain the carbon material. The preparation method has the advantages that the carbon material is prepared from the compound containing three alkynyl under a very mild condition by virtue of the high activity of alkynyl, the preparation efficiency of the preparation method is greatly superior to that of an existing preparation process of high-temperature carbon materials, the microstructure of the obtained carbon material is easy to control, the molecular structure of the carbon material can be designed, the structure of the carbon material can be adequately regulated and controlled according to practical application demands, and the obtained carbon material is good in conductivity and stability and has relatively excellent processability. Meanwhile, the method is simple in process, low in cost, wide in application range and relatively beneficial to industrial large-scale production, and the carbon material can be further popularized to more application fields requiring mild operation conditions.

Description

technical field [0001] The invention belongs to the field of carbon material preparation, and in particular relates to a high-conductivity carbon material and a preparation method thereof. Background technique [0002] Carbon materials have played an increasingly important role in modern society, and the development of carbon materials has provided important development opportunities for various industries. In recent years, the world is facing the challenges of gradually warming climate, increasingly serious pollution, and the year-by-year reduction of non-renewable fossil energy. Countries around the world are calling for cleaner energy, including fuel cells, lithium-ion batteries, and supercapacitors. , solar cells, and microbial fuel cells have become key scientific and industrial development projects in recent years. As we all know, the above clean energy sources are all inseparable from carbon materials with excellent performance, especially it is hoped that high-perfo...

Problems solved by technology

However, these materials are produced at extremely high temperatures (higher than 800°C), and cannot meet the urgent needs of various energy systems in electrochemical energy applications.

For example, the current carbon materials cannot realize the low-temperature carbon coating technology required by some potential high-energy-density battery electrode materials, so as to improve the cycle, safety and fast charging performance of the electrode material through the carbon coating of the electrode material. ; Another example is that the current carbon materials do not have the high specific surface area, high conductivity, and high adhesion to the catalyst required by the cathode and anode of the fuel cell, and at the same time need to have high-efficiency transmission of gases and liquids; another example is light Catalysts require a certain semiconducting carrier to increase the force between the catalyst and the carrier, and to further optimize the photocatalytic performance of the catalyst. However, the current carbon materials cannot be used as such a carrier.

[0004] Many of the applications mentioned above pose serious challenges to the traditional production methods of carbon materials and the properties of carbon materials
