Huaxing Group has also continued to carry out research and development on graphene materials for nearly ten years, and has finally seen great results so far. ∝ 8∝8∝ read ∝ books, .◆.o+

At present, in the application of graphene materials, the group company is mainly used to manufacture conductive inks, fuel cells, lithium batteries and solid supercapacitor batteries and coatings.

Two-dimensional graphene is difficult to use, graphene with intact structure has high chemical stability, the surface is inert, so it is insoluble in water and commonly used organic solvents, the interaction with other media is weak, and there is a strong van der Waals force between graphene sheets, which is easy to aggregate, which has caused great difficulties to the further research and application of graphene.

After years of painstaking development and exploration of dozens of directions, Huaxing Group finally prepared a variety of functional graphene materials.

It mainly focuses on catalysts, focusing on the three fields of photocatalysis, metal oxide catalysis and electrocatalysis, especially in the research and development of three-dimensional graphene materials as catalysts to reduce the use of precious metals.

The R&D team of hydrogen storage materials led by Chen Xiaojun of the Institute of Electrochemistry began to use three-dimensional graphene materials to design new compound structures to increase the number of hydrogen atoms and release hydrogen atoms when needed.

Chen Xiaojun and his team have used computer simulations to design the mechanism of this new material, which combines boron nitride nanotubes and graphene to form a unique three-dimensional structure.

In fact, the principle of hydrogen storage in these materials is not complicated, and the use of columns to support the load like building a house can create more space, but the difficulty lies in how to further increase the number of hydrogen atoms put in it and release them when needed. ⊕ 8⊕8⊕ read ⊕ books, .◇.o≮

Chen Xiaojun: That's what they're studying.

After Yang Jie came to the Institute of Hydrogen Storage Materials, Chen Xiaojun also reported to Yang Jie that in the experiment of graphene composites, this material has the best hydrogen storage capacity at room temperature and environmental pressure, and now they have found the catalyst and conditions for the release of hydrogen from this material, and are developing a new type of hydrogen oil.

Of course, they also designed another graphene composite material to prepare a separator material for use in the previous hydrogen-oil separation equipment, which can obtain higher purity hydrogen.

In addition to these graphene materials used in electrode materials and electrolytes, the Machine Tool Research Institute has also begun to use lubricating oils, slurries, cutting fluids and other products.

These polymer graphene graphene graphene has good dispersion, there are many functional groups on its surface, it can be easily grafted with other related materials, and can exist stably in the lubricating oil for a long time, so that the original ordinary lubricating oil has better wear resistance and thermal conductivity characteristics.

Compared with gallium nitride materials, graphene can only be used through specific functional group modification, which requires enterprises to invest a lot of effort to develop different graphene materials, Huaxing Group has only developed more than ten kinds of graphene materials with different functions, so it is destined to be used only in some specific technical fields.

Huaxing Group has the greatest strength for gallium nitride materials, because gallium nitride materials have now been shipped to semiconductor devices, with greater economic benefits and the advantages of replacing silicon-based materials.

Graphene materials do not have this possibility, many materials are not worse than graphene materials in some specific aspects, and they are cheaper, and the general modification can also continuously improve the performance.

Of course, Huaxing Group will not stop the research and development of graphene materials, but only in some specific areas where graphene materials have advantages.

Since Huaxing Group was the first to become the discoverer of graphene materials, graphene materials have become a gimmick for domestic and foreign corporate speculation, especially some listed companies have used it to speculate, so that their companies can make money in the stock market.

Especially in recent years, the concept of graphene has been very hot, and many companies have nothing to do with graphene materials at all, and they are also very shameless to hype graphene, as if graphene materials have become universal materials.

Huaxing Group is not listed, and has been carrying out various research and development of graphene materials for more than ten years, and now it is the best company in terms of material preparation and process equipment and material application, and it also has a large number of technical patents in its hands, but it is very low-key.

Now the only domestic large-scale production of graphene materials is only Huaxing Group Company, as early as 03 years to build an annual output of 30 tons of graphene material production, to now this factory has expanded the production capacity to an annual output of 300 tons.

Now that Huaxing Group has mastered the technology of preparing three-dimensional graphene materials, Yang Jie also decided to quickly build a new production line to increase the number of three-dimensional graphene foam materials.

The three-dimensional graphene foam material prepared by the Institute of Electrochemistry has pores uniformly distributed in the foam body, and the pore size is 20 nanometers, which increases the specific surface area of the electrode, improves the conductivity of the graphene network, and has a porous channel that is conducive to ion transport in the electrolyte, and can now be used in electrode materials, catalysts and thin film materials on a large scale.

In the past, graphene, as a planar two-dimensional material, was very easy to stack between sheets, resulting in a great reduction in specific surface area and pore volume, which was not conducive to the improvement of battery capacity and energy density, and had poor stability, and was easy to fall off after long-term use, which seriously affected its application as a battery electrode material.

Moreover, this material uses microspheres as a template, which can easily control the size of the pores in the material to obtain foam materials of different specifications, this honeycomb material has the same stability as diamond, and has good dispersion as a polymer material, and can easily prepare a graphene material with a uniform material of tens of nanometers, which opens up the application of graphene materials at once.

If this material is to be used on a large scale for electrode materials, catalysts, and thin film materials, the production scale will be expanded to at least several thousand tons per year.

Yang Jie also agreed to the application of the Institute of Electrochemistry to build a 1,000-ton material production line this time, and if the capacity supply is insufficient, it will continue to expand the production capacity at that time.

The next day, Wan Zihao also led more than a dozen experts and professors to Tanzhou City, and Yang Jie also met with them.

Huaxing Group also provided a small number of three-dimensional graphene microchips to Tongji University for research, and Tongji University also provided several technical patents for three-dimensional graphene materials to Huaxing Group. 11
