Chapter 980: Graphene Technology Breakthrough!

In terms of construction machinery and equipment, the main producers are Germany, Eagle Sauce, Neon, Gallic Chicken and other Western countries, there are more than 10 top companies in the world, and the world market is mainly concentrated in North America, Europe and Asia.

Yang Jie also hopes that Huaxing Construction Machinery Company can also become an evergreen existence, deeply rooted in this field, after all, clothing, food, housing and transportation are needed by everyone in the world, and construction machinery and equipment have always had market demand.

Of course, Ishikawajima Construction Machinery has been immersed in the field of construction equipment for decades, and there are many equipment still in operation all over the world.

The management of Huaxing Construction Machinery Co., Ltd. has begun to remanufacture Ishikawajima construction machinery equipment, mainly using Ishikawajima's global dealer network to repair equipment, inject new vitality into old equipment, and provide customers with reduced product life cycle operating costs.

Yang Jie also hopes that this business will become an important business of Huaxing Construction Machinery in the future, because from now on, the design process of the entire product of Huaxing Construction Machinery Company is completed by its own company, so the technical patent of the product subsystem will be in its own hands, and it does not need to be clamped by other parts manufacturers.

In the past, a large part of the components of many construction equipment on Ishikawa Island were designed by these parts manufacturers, and the technology patents were in the hands of these parts manufacturers, and the remanufacturing business had to be purchased from these manufacturers, but in fact, it did not make much money.

However, from now on, the design of these subsystems will be completed by the R&D and design department within Huaxing Group, getting rid of the dependence on component suppliers.

Although it is not a lot of money to make money from these parts manufacturers to carry out these businesses, Yang Jie also hopes that the design and technical patents of these subsystems will be completed by the group company itself within five years.

Huaxing Construction Machinery Company also has a business to carry out is the design, manufacture and production of large-scale mining equipment, after all, the domestic technical foundation in this field is also very weak, leaving a lot of market space for the company.

After meeting with these expert groups from the Neon Country, Yang Jie rushed to the Institute of Electrochemistry.

In the graphene material laboratory, Gao Tianming, who is responsible for the research and development of graphene microsheets, is excitedly explaining to Yang Jie a new type of physical liquid-phase mechanical exfoliation method developed by the laboratory.

Subsequently, Yang Jie was also shown the very thin three-dimensional graphene microsheets prepared by this equipment.

"Yang Shao, we also sent this three-dimensional graphene microsheet to the Shenguang light source to observe the microsheet, the internal graphene atom arrangement is very stable, there is no graphene atom stacking, and the conductivity is very good.

Gao Tianming said excitedly: "This preparation process does not use the commonly used concentrated nitric acid treatment nitriding process, we use a simple and low-cost technology to solve nitrogen oxide pollution, the effect is very good, not only greatly reduce the cost of graphene microsheet preparation, but also very friendly to the environment." ”

Before the process of graphene preparation of Huaxing Group Company, the process of using silica as a template, using the vapor deposition process, using methane as a carbon and nitrogen source to grow graphene materials, and then using hydrofluoric acid to corrode off the template to obtain three-dimensional graphene block materials, the cost of preparation is really high, these materials are mainly provided by Aode Technology Company for the production of supercapacitor battery modules, although the performance of supercapacitor batteries of Aode Technology Company is very good, but it is really expensive.

For example, supercapacitor batteries installed in energy storage stations and fuel cell vehicles, as well as high-speed railways and weapons and equipment are five or six times more expensive than lithium batteries on the market, but Yang Jie insists on using them in these products.

Huaxing Group also has a stake in Aode Technology Co., Ltd., a subsidiary of Tongji University, and the two sides are very close in the research and development of graphene materials in supercapacitor batteries.

Huaxing Group is mainly responsible for the preparation process and equipment of graphene materials, and Tongji University focuses on the application technology of graphene materials in supercapacitor batteries and batteries.

In recent years, a lot of research has been carried out on the electrode, electrolyte, separator and other aspects of supercapacitor batteries, and Tongji University has also published a number of top papers in the international top natural comprehensive science journals.

Under the leadership of a number of experts, Aode Technology Co., Ltd. has made great breakthroughs in the development of hydrogel electrolytes and composite electrode materials for the preparation of graphene with aerogels.

As the key factors affecting the performance and production cost of supercapacitors, electrode materials and electrolytes have been listed as key research areas of Tongji University in research, and Tongji University has been at the forefront of the world in this regard.

This is mainly because Aode Technology has now become one of the top battery suppliers in China, and has also become a world-renowned battery supplier, the company not only produces supercapacitors, but also produces lithium batteries and ternary lithium batteries, mainly for Huaxing Group and other companies at home and abroad to provide batteries for digital electronic products.

The turnover of the battery business of Aode Technology Company has reached more than 20 billion, and the gross profit can reach more than 30 percent, which is very profitable.

Huaxing Group purchased the patent license of Bell Labs' polymer lithium battery as early as 2,000 years ago, and also recruited several technical experts in this field to establish Aode Technology Company. Through experiments, adjustments, and improvements in the electrolyte formula, we have made a non-blowing battery to provide batteries for our company's products.

Later, Tongji University also invested in Aode Technology Company, and a group of experts from Tongji University in battery technology also joined in.

Aode Technology Co., Ltd. has brought a steady stream of funds to Tongji University, and has also increased the research and development of battery technology, which can be said to have become the strongest university in battery technology.

Tongji University has now made a major breakthrough in electrode material technology last year, successfully embedding graphene microsheets into the molybdenum disulfide layer, which is caused by the in-situ carbonization of polyetherimide embedded in the molybdenum disulfide layer.

This process is mainly to mix the nanosheets of polyetheriamide and molybdenum disulfide in water, and the polyetheriamide molecules of these two materials are easily adsorbed on the surface of the molybdenum disulfide nanosheets due to the electrostatic attraction of the two, and are embedded in the molybdenum disulfide layer under the action of ultrasound.

After freeze-drying, the mixture forms an aerogel-like three-dimensional molybdenum disulfide/polyetherimide complex, and after freeze-drying, graphene is embedded in the molybdenum disulfide material by calcination, which exposes more active sites due to the embedding of graphene-like carbon between the molybdenum disulfide layers, creating a new ion and electron transport pathway, so that the monolayer of molybdenum disulfide exhibits excellent electrochemical properties.

Through experiments, this electrode material has an ultra-high pseudocapacitance, and now this material has begun to be used in supercapacitor batteries and other battery electrodes.
