Super Copy of Great Power Technology

"I didn't expect that after all the twists and turns, I would go back to my old job. Ruida Aerospace. What a coincidence. The express company I am working for now is also called Ruida. I don't know if it is a coincidence or not." Hang up the phone. , put away the phone, Cao Yifei sat in his seat and thought for a while, then hurriedly started the tricycle and ran towards the express station.

In the afternoon, Qiao Ruida was testing the newly developed graphene battery at Ruida Research Institute. I witnessed with my own eyes that a set of graphene batteries the size of a school bag drove the air conditioner through an inverter and ran normally for an hour, consuming only about 10% of the battery's power. The same set of batteries, after being discharged, was quickly charged from 0% to 100% in only eight minutes.

After the test was completed, Qiao Ruida nodded with satisfaction and said, "The graphene battery you made this time basically met my requirements. Is there no problem with mass production?"

Fan Decheng, the leader of the battery research team, said with a grimace: "Mr. Qiao, this set of batteries is made according to the standards of the lowest-end graphene battery in the technical information you provided. Even so, this The cost of a set of batteries has reached 50 yuan. Even if such expensive batteries are mass-produced, not many people can afford them, right?"

"A set of batteries costs 50 yuan, and it is only the lowest-end graphene battery. I remember that the production method mentioned in the information is not very simple. How can it be so expensive?" The relevant information on graphene batteries was obtained by Qiao Ruida twenty years later. He found it on the Internet. He knew the specific production process very well. He really didn't understand why something so simple could be so expensive.

"Mr. Qiao, the technical information you provided is really refreshing. The graphene battery structure mentioned above is also very clever. It is not too troublesome to produce. It can be easily prepared with existing equipment. The problem is to produce the battery. The graphene raw material must be electronic grade graphene, which costs hundreds of dollars per gram. And our battery uses two kilograms of graphene, so the cost is not expensive. "Fan Decheng is a typical example. A man from science and engineering, he spoke straightforwardly. He highly praised the technical information provided by Qiao Ruida, but also felt helpless about the high price of the raw material graphene. The technology is good, but the cost is too high and mass production is not possible.

Qiao Ruida patted her forehead and said suddenly: "It turns out that the problem lies in graphene, so it will be easy to solve. In our research institute, another group is developing a new graphene preparation method. If the test is successful, the electrons can be The cost of high-grade graphene has been reduced to a few cents per gram.”

Graphene is a very magical two-dimensional material. Since it was prepared by two British scientists in 04 using a mechanical exfoliation method, it has been a star material in the scientific research community. Its various magical properties are constantly being discovered, and its various uses are constantly developed. It is no exaggeration to say that it is the king of materials in the new century. However, these high-tech products developed using graphene materials rarely appear in the consumer market. For no other reason than the cost of graphene is too expensive. Electronic-grade graphene with the highest standards sells for 200 yuan to 500 yuan per gram, and even the roughest multi-layer powder graphene sells for more than 20 yuan per gram.

Now the graphene battery developed by Ruida Research Institute also encounters the problem that the cost is too high and cannot be mass-produced and promoted. If you switch to other companies or scientific research institutes, this problem is basically unsolvable. You can only publish a few papers on scientific research results, register a few patents, and if you have connections, you can also use them for awards, and that's it. But the same problem is not a problem when faced with a cheater like Qiao Ruida. Isn't it just electronic grade graphene? As long as you have a sample, take a photo, use the golden finger, and copy it in batches, you can get whatever you want. As for the cost, it is almost zero. Even if he doesn’t cheat directly, Qiao Ruida can still find a low-cost preparation plan for graphene from the Internet twenty years later, COPY it, and significantly reduce the cost of graphene. Coincidentally, among the new batch of technical information he handed over to the institute a few days ago, there was information on the production of graphene by microbial exfoliation. The project has been approved for research and development, but the time is still short and a breakthrough has not yet been achieved.

"It's just a few cents per gram. It's incredible. If graphene is really so cheap, then the capacity of our graphene battery will be increased three to four times, and the energy density will be higher than that of gasoline. And the amount of graphene used will not be a problem." With the increase, the charging speed of the battery can continue to be accelerated, and it is not impossible to achieve fast charging in five minutes." Hearing this news, Fan Decheng was extremely surprised. If the price of black gold materials such as graphene can be reduced, then they will. There are so many places where these researchers can play their part.

The most criticized thing about new energy vehicles is that the charging speed is too slow and they are not as convenient as fuel vehicles. You can refuel and go immediately. Take the MINIEV, the best-selling model of Reda Auto, for example. Even for high-end models equipped with fast charging interfaces, it takes at least an hour to charge using a fast charging pile. If it is a basic model without a fast charging interface, the charging speed is even more frighteningly slow. It takes at least 0 hours to charge from 100% to 14%.

Another criticism of new energy vehicles is that they have a relatively high weight and a relatively long braking distance. This is actually because the energy density of lithium batteries is relatively low. To meet the basic battery life needs of a car, a large number of lithium batteries need to be accumulated. This is why new energy vehicles are always hundreds of kilograms heavier than fuel vehicles of the same model. The most powerful lithium battery now has an energy density of only 300Wh/kg, while the energy density of gasoline is 4.6x10 Joules/kg. When converted into a power density, it is about 7Wh/kg, which is about 12222 times that of lithium batteries. . Improving the energy density of rechargeable batteries to the level of gasoline is the ultimate dream of countless battery developers. Now when he thinks that this ultimate dream will become a reality in his own hands, Fan Decheng's hands are trembling with excitement.

"If you want to continue to study in depth, of course there is no problem. If you don't have enough graphene, you can report it directly. I should be able to get you a batch of cheap electronic grade graphene through special channels for experiments. But first The graphene batteries that are mass-produced and put on the market can only maintain the energy density of this set of sample batteries. It is already a black technology that is ten times higher than that of existing lithium batteries. If you take it out, it will shock a lot of people. People. If you have better research and development results in the future, they will be used as technical reserves and then released one after another in a few years. After all, only by continuous updates and iterations can the economic benefits be maximized.”

While Qiao Ruida was telling about the bright prospects and sales plans of graphene batteries, the cell phone in her pocket suddenly rang. He took out his cell phone and looked at it, and found that the call was from his secretary He Shuhui. Several of Qiao Ruida's secretaries have his personal mobile phone number, but they all know the rules and will not call to disturb his private life unless there is something very urgent. Now Xiao He called him because something important happened.

After the call was connected, He Shuhui's voice came from the receiver, "Mr. Qiao, the Cao Yifei recommended by the headhunting company has arrived at the front desk of the company. Do you want to come back to interview him in person, or arrange for someone from the company's human resources department to receive him?"

Qiao Ruida pondered for a while and said: "I'd better go back. After all, we are recruiting the general manager of a company with a scale of 100 billion. I won't worry unless I see it with my own eyes. Xiao He, please arrange for Cao Yifei to stay in the reception room first. I'll be there soon." After hanging up the phone, Qiao Ruida said to Fan Decheng and a dozen other researchers: "This graphene battery works very well. Thank you for your hard work. Please double the bonus this month. After the industrial mass production process is developed, and when another R&D team’s microbial exfoliation method for producing graphene is successfully developed, we will build a dedicated graphene battery factory to produce various types of graphene batteries. That’s all. Come on, keep up the good work, I have something else to do, so I’ll leave first.”

After a few words of explanation, Qiao Ruida quickly left the battery laboratory and took the stairs downstairs. After the Reda Technology R&D Department became independent and established the Reda Research Institute, it remained in the original scientific research building and did not move. After the restructuring of the Ruida enterprise group, the group headquarters was located in the original Ruida Technology Office Building, but now the name of this building has been changed to the Ruida Group Headquarters Building. As a result, many senior management positions have been adjusted, but the office location has not been changed at all. Since the two buildings are very close to each other, Qiao Ruida only walked for ten minutes from the scientific research building back to the Ruida Group headquarters building.

Qiao Ruida took the special elevator on the top floor and arrived at the 66th floor of the headquarters building. As soon as she stepped out of the elevator, secretary He Shuhui came up to her and reported: "Mr. Qiao, I have arranged for Cao Yifei to be in the reception room No. . You have to go and see him now." him?"

As Qiao Ruida continued to walk forward, she said: "I will go back to the office to get two documents first, and then go to see him."

Five minutes later, Qiao Ruida pushed open the door of the reception room and saw a middle-aged man in front of her. She raised her head in astonishment and met his eyes. This middle-aged man should be Cao Yifei, a talent recommended by a headhunting company. I saw that this person had a face with a Chinese character, his eyes were as calm as water, and his stubble was cleanly shaved. His hair may have been unkempt for a long time, so it looked a little uneven. Perhaps because he is middle-aged and lacks exercise, Cao Yifei has gained some weight. What surprised Qiao Ruida the most was that Cao Yifei was actually wearing a Reda Express uniform at this time. The huge Reda LOGO on the front of the clothes was so eye-catching that it was absolutely impossible for him to admit his mistake. If it weren't for Cao Yifei's age, Qiao Ruida would have thought she saw a courier boy from her own courier company.

"You are Mr. Qiao Ruida Qiao, I have long admired your name!" After all, you are a person who has been the vice president of a state-owned enterprise. There is absolutely no problem in accepting people and entertaining guests. Cao Yifei stood up, took the initiative to extend his hand, and spoke politely without being rude.

"You are Cao Yifei, Mr. Cao. Nice to meet you!" Qiao Ruida also extended her hand and shook it with Cao Yifei.

"Not to mention the bravery of a good man, I am just a grassroots courier now, and I don't deserve to be called Mr. Cao. Mr. Qiao can call me by my name, or Lao Cao." Cao Yifei quickly waved his hand and corrected Qiao Ruida's wrong title. When speaking, Cao Yifei's eyes were still calm and calm, without any embarrassment or any blame.

"Okay, you're much older than me, so I'll call you Lao Cao. Come on, Lao Cao, let's sit down and talk. Xiao He, make two cups of tea and bring them over. Remember to use the best one from the box in my office. Biluochunpao."

Qiao Ruida invited Cao Yifei to sit down and chatted casually for a while. Finally, he couldn't help his curiosity and asked: "Old Cao, you just said you were working as a courier at Ruida Express Company, a subsidiary of Ruida Group. Are you working? The clothes you are wearing seem to be the uniforms issued to couriers by our express delivery company."

"Mr. Qiao, you guessed it right. I do work for Ruida Express Company now, working as a courier at the express station in HR District of Beijing. After my business failed, I owed a lot of debt. In order to support my family, I had to work everywhere. . It’s just that I’m too old and have changed many jobs, but the salary is not very high. Working as a courier at Ruida Express is the highest-paying job I have found in the past few years. I work hard every day. With a monthly salary plus bonus, I can get 15,600 yuan. In addition to providing for my family’s daily expenses, I can also pay back some bank interest.”

From the tone of his voice, it can be heard that Cao Yifei is under a lot of pressure. Not only does he have the burden of his family, but he also has millions of dollars in debt from the bank. But in the face of difficulties, he did not back down, but chose to face it bravely. In order to earn thousands more yuan every month, he was willing to work hard as a courier. Qiao Ruida has read the reports submitted by Ruida Express and knows that ordinary couriers can only get a salary ranging from two yuan to five yuan for delivering a package, but Cao Yifei can get a salary of 15,600 yuan per month. With a casual calculation, you can figure out how many express deliveries he has to deliver in a day. Many young people cannot resist this hard work, not to mention that Cao Yifei is still a middle-aged man in his forties.

While the two were chatting, He Shuhui had already brewed two cups of tea and served them to them. Qiao Ruida picked up the tea cup, took a sip, and said, "Old Cao, let's start the formal interview. First, tell us your views on private aerospace companies."

Cao Yifei pondered for a moment, organized his words, and then said: "In my opinion, aerospace is an industry with high investment, high risks, and very difficult to make profits. If nothing else, the cost of a medium-sized launch vehicle is only 3000 More than . A private aerospace company with no technical reserves has invested more than billion just to develop such a medium-sized launch vehicle." (End of Chapter)
