Chapter 15

Graphene battery, a new energy battery, is developed based on the characteristics of lithium ion shuttling between graphene surface and electrode.

In the field of mobile devices, battery endurance and charging speed have always been one of the focuses pursued by major brands and consumers. However, the service life of graphene battery is twice as long as that of lithium battery and four times of that of hydrogenated battery. The weight of graphene battery is only half of that of traditional battery, and the cost of graphene battery will be 77% lower than that of lithium battery. From the performance point of view, a 5000 Ma battery can be fully charged in half an hour. After using 2000 times of discharge, the decay rate is less than 15%, while that of ordinary lithium battery is 40% - 80%.

But all of these graphene batteries are laboratory products, and none of them can be put on the market. The main reason is that there is no high-quality low-cost graphene products. Almost all the popular methods for preparing graphene have the disadvantage of serious pollution. Therefore, if we want to make a breakthrough, it is very important to produce large-scale high-quality graphene.

"That means our laboratory is at the same level?" Lei Tiantang listened to Zhao Junxian on the introduction, want to ask.

"No, Mr. Lei. At present, we are still in the research and development stage in the field of batteries, and we have no good results, because we focused on large-scale graphene production technology before." Zhao Junxian explained.

His previous boss wanted to make a short-term profit. Although his investment in the laboratory was also very positive, he had little support for the graphene battery technology which had not been broken through for a long time. So the lab's experience on batteries is not very good, they are just repeated experiments to track the latest experimental reports.

"Well, I know the details. As for the large-scale high-quality graphene, I have it here, and how many I want. In the future, our company can also produce high-quality graphene, so I hope you can adjust your research direction to the specific application of graphene in the future Lei Tiantang envied Zhao Jun.

What preparation method can be cheaper than him? His cost is almost zero, that is to buy graphite to spend some money, and then use absolute field to control it. Of course, he can't just produce all of them by himself. It's OK to sell them all at once. If they sell more, they can't do it. After all, for materials like high-quality graphene, the outside world will also pay attention to its origin, so we must find ways to make the company have the ability to produce this kind of high-quality graphene.

"Mr. Lei, do you have high quality graphene?" Zhao Junxian is a little skeptical. It's not that he doesn't believe the boss, but that he has never heard of a company that can produce high-quality graphene on a large scale. The boss has just acquired the company. The company's backward production line has not been started. What's more, the company does not have this technology. Where does graphene come from?

"Yes, I have, and you can have as much as you want. As for where it comes from, I won't tell you. It's a company secret. What's more, I decided that the company would officially sell high-quality graphene, but in that case, other people would be in the same running line as you. Are you confident to compete with them? "

How could Lei Tiantang tell us the origin of graphene? Besides, no one believed it. Anyway, he only plans to take out this once, and if someone really wants to know, he can send him away with a company secret.

"There is no problem with this. My team and I still have the confidence that we need to invest more in the laboratory and purchase more experimental equipment." Zhao Junxian confidently said to Lei Tiantang. He came to such a small company after studying abroad because it was a company willing to invest money in the laboratory.

"There's no problem with this. What equipment do you need? I'll arrange people from the company to buy it." Lei Tiantang's investment in the laboratory was not hindered. After all, the laboratory wants to have achievements. In addition to personnel, experimental equipment is also an important factor.

"No problem, Mr. Lei. As long as the equipment arrives, I believe our breakthrough is just a matter of time." Zhao Jun envied the way.

"Well, that's good. Then I'll get the business department to start contacting buyers who need high-quality graphene." Lei Tian Tang laughs. He didn't have much hope about when the laboratory would make a breakthrough, but he was still willing to invest in it, because if there was to be a major breakthrough, the benefits of using graphene to make finished products would far exceed the income he earned from selling materials.

After Zhao Junxian left, Lei Tiantang contacted Liu Antu, the newly recruited business manager of the company, and asked him to be responsible for selling the graphene he provided to companies and laboratories that needed high-quality graphene.

As for the pricing of graphene, Lei Tiantang has made an investigation. At present, the price of low-grade graphene on the market is about 2000 yuan per kilogram, while no one is selling high-quality graphene. So as soon as his graphene is taken out, he can basically monopolize the high-end market.

Lei Tiantang wanted to sell a large number of graphene, so the price could not be too high. He planned to sell a lot of high price graphene at first, and then the high price graphene was digested and sold in large quantities at a reduced price.

So the price of the first batch of graphene is 8000 yuan per kilogram. This price can be said to be very high. However, this is the first time that high-quality graphene has appeared in the market, and the sales volume will not be too low.Lei Tiantang arranged the company's business and drove to the warehouse he rented before. The high-quality graphite he ordered two days ago was put here.

Looking at the graphite, Lei Tiantang began to imagine the companies and laboratories buying them like crazy, and then they turned into money.

Shaking his head, Lei Tiantang couldn't help laughing. He was also a little happy with his divergent thinking. Concentrate on it, Lei Tiantang directly controls the absolute field in the warehouse and begins to process these graphite.

Lei Tiantang processes them into 20 inch flake single-layer graphene, because the largest single-layer graphene in the world is only 15 inches, which is also made by domestic laboratories. Moreover, it is a laboratory product, and there is no way to mass produce it. Now, the scale of Lei Tiantang's production is factory level, and the quality is better than that of the laboratory. You know, stone The larger the sheet size of graphene, the wider the scope of its use.

Lei Tiantang looked at the processed graphene and thought, brother, I now regard them as the first generation of export products. When other companies can produce 20 inch products in the future, he is introducing larger sizes! The high-end field of this industry is brother's private plot!

Looking at the graphene that has been processed, Lei Tiantang takes out the sealed barrel made of stainless steel that he bought, and then encapsulates the graphene in the barrel. Then he called Liu Antu, told him the address of the warehouse, and then left the rest to him. As for the safety of these unattended graphene, he would not worry, because most people would not know that these black things were worth a lot of money.

As expected, Lei Tiantang did not expect. With the company's salesmen taking samples to promote sales, each company and laboratory all placed more or less orders. Finally, Lei Tiantang was happy. It's true that this wave has made too much money. The combined sales volume of companies and laboratories from all over the world has reached more than 12 tons, and the total sales volume is more than 1 billion yuan! And this is only the result of the first purchase!

Although the next time the company can produce and sell again, the price will drop, but it will not drop much, because now this business can be regarded as the exclusive business of Lei Tiantang. Don't worry about no buyers.
