Chapter 13

When Xiang Qianjin was studying a new plan, someone came in and said anxiously, "Xiang Qianjin, put down the work first. Professor Ivan has something to do with you."

"Professor Ivan? What does he want from me? " Xiang Qian asked suspiciously.

"Go on! Otherwise, our headmaster Feng will become the criminal of history! Hurry up Being called away by counselors, Xiang Qianjin is also helpless. Although I don't know what's going on, I can guess.

After all, in this era, China is superstitious about foreign experts. Basically, foreign experts are the absolute authority. They are determined by foreign experts. It is estimated that Mr. Feng will be completely destroyed in the future. Xiang Qianjin came to the conference room with a headache. He calmly pushed open the door of the conference room. Xiang Qianjin said in a low voice: "Hello, Professor Ivan."

"You?" Professor Ivan stares at the young Xiang Jin outside the door. This young man is so young! He's only twenty, isn't he?

Professor Ivan was surprised and asked, "are you going forward?"

Xiang Qian nodded and said calmly, "yes, I am Xiang Qian."

Professor Ivan looked at him suspiciously, and then Professor Ivan said in a low voice: "according to my experience, this scheme can't be made by one person, can you explain it to me? If you are a foreign expert Professor, I may be able to trust you, but you are a student. It's really unbelievable that this kind of thing happened in China. "

Xiang Qianjin snorted coldly. Then he cleared his throat and replied in the same language as Ivan: "first of all, I want to thank you for looking at my plan carefully, Professor Ivan. But what I have to tell you is that we Chinese are no less than others. Why is this incident reasonable abroad and unreasonable at home? Isn't that good? Of course, Huaxia is backward in technology as a whole. It's not because we Huaxia people can't do it, but because we have experienced wars and invasions all the year round, so our technology has never developed. But today's China is totally different. We haven't fought for many years, and the domestic peace will continue. We have a safe environment to carry on. Our scientific research personnel can serve our motherland with an open heart, and our predecessors have given us a peaceful and prosperous motherland, We also have the conditions to climb high technology. Why can't we go on the road of high technology? "

Ivan was a little confused by Xiang Qianjin's words. He said with a little apology: "sorry, classmate, I'm not belittling your country, but this project really needs too much foundation to do. How did you complete it?"

"Learning, trying to surpass. As long as we pay attention to their trends, guess their intentions, and have enough creative thinking and boldness, I don't think it's difficult. " Xiang Qianjin said seriously.

Ivan whispered, "but it needs a solid foundation."

"Yes, and I have this point. As a student, I come to study to learn the foundation. My family is not rich, so I have a direct situation in front of me. If I want to change my life, I have to make more efforts and make more efforts. Therefore, I suggest that you should give up the inherent prejudice against us in China. Isn't it prejudice that science should eliminate first? " Xiang Qianjin finished, Ivan nodded, he said in a low voice: "well, I apologize to you, Xiang Qianjin. This is really my problem. So, since you are responsible for this project, can you answer some of my questions? "

"Of course." He went back with a smile on his face.

Ivan calmly said: "you mentioned the problem of lithium iron phosphate, one of which is low density and large volume. But you still want to miniaturize the battery in this scheme. Can you explain the future scheme?"

"Spheroidizing, reducing the gap between particles and increasing the overall density is the best solution at present. The material itself has its own characteristics, but we can make the particles nanometer and then make the material finer! But because of its low diffusion coefficient, we can not evenly spread coating, so we can consider using ultrasonic dispersion device. Or add dispersant, but I think it's only a temporary method. I prefer adding special linear conductive agent. Because there is another problem with LiFePO4, that is, poor conductivity and additional adhesion, which requires us to keep up with the steps in the subsequent product development. Not only that, but also the negative electrode material, LiFePO4, which we use on the positive electrode, I don't plan to use graphite as the negative electrode material, I plan to use lithium titanate. Of course, what I'm talking about is the research on large batteries, and miniaturization is the process of seeking stability. "

After Xiang Qianjin finished, Ivan looked at Xiang Qianjin in surprise and said, "lithium titanate? Do you really think so? "

"Yes, not only that, I also have an idea that the next development direction of LiFePO4 is lithium iron titanate battery, which has fast charging, amazing high charging energy and super long life. Although the problem of miniaturization is further increasing, I intend to use this kind of battery in large mechanical fields, even in the military." Xiang Qianjin said here, Ivan looked at Xiang Qianjin in amazement. Is this a student?Isn't this a young expert from a foreign super laboratory who has come out to harm people?

Xiang Qianjin's mastery of technology and his advanced thinking have made Ivan confirm that this young man, let alone the future, should be a national treasure expert now! Ivan nodded and said, "I apologize again for what I said just now. Oh, no, my dear davaris, I'm very interested in your idea. If you are really willing to develop, I'd like to join your R & D team. "

"Welcome to join Professor Ivan, but we need to come step by step. At present, the problem of lithium titanate is not easy to solve, so we still have a lot of topics to study in the aspect of battery, such as the problem of super capacitor. So what I'm going to do now is to take a quick step across the times. We still need to do everything step by step. Now we mainly want to make the blue picture better. "

Ivan said happily, "well, you're right. I support you in this matter. "

When Ivan was chatting with Xiang Qianjin, principal Feng realized that he almost became a criminal of history. Professor Ivan is an internationally recognized battery expert, and he has been studying batteries all the time. His specialty is the battery design of aerospace and naval vessels. Xiang Jin has been highly appreciated by him. The school is really lucky this time!

Principal Feng said with a smile: "ha ha, go ahead, are you doing research on lithium titanate now?"

"Yes, principal."

"In this way, I will give you a scientific research office, and you will go to the scientific research office in the future to do serious research and development, and strive to make great contributions to the motherland!"

Liu Ruoxin coughed twice, then calmly said: "cough, headmaster. In fact, Xiang Qianjin can also go to our company's R & D building. He... Is now an expatriate learning employee of our company, and his tuition fee will be fully borne by us in the future. You just need to send the bill to our company. However, you can rest assured that Xiang Qianjin can still participate in the school's R & D projects to what extent he can read, but it can only represent our Huacheng research and development. "

Headmaster Feng looked at Liu Ruoxin in surprise. He said suspiciously, "Liu Ruoxin, it's fast enough to start!"

Liu Ruoxin said in a low voice, "if I start slowly, I will lose this important opportunity. I'm a businessman. Of course I have to start fast."

Ivan laughed: "Oh, ha ha ha, I think this kid goes to the civilian technology company can create greater achievements, after all, he is too young, too restrictive in the national institutions, it is not easy for him to play a role, so it is better to let himself out of a new world."

Headmaster Feng said with a smile: "ha ha, Professor Ivan is right. Our school can unify his on-the-job study, but our school must share the right to use the technology of R & D projects. You always agree, I'll sign for you, but you don't agree... "

"I promise. But when Xiang Qianjin is in school, he must join the research in the name of Huacheng scientific research, which is also my bottom line. " Liu Ruoxin said with a smile, principal Feng nodded, he said with a smile: "you girl, you are really a ghost! In this way, you Huacheng scientific research can participate in the development of national projects, which is beneficial to your company! Sure enough, the businessman.... is a businessman
