Chapter 2

The best way to enter Huacheng is to take this project down and use it to make Huacheng go up the hill. At that time, Huacheng's scientific research was through financing, and this financing is the key to bury mines in the future. If Xiang Qianjin wants to change all this, it must help Huacheng win the project. Stop financing!

In 1997, China's science and technology industry was basically monopolized by foreign countries. Whoever breaks the monopoly can earn the first bucket of money, time! It takes time to move forward! And this time, now only 20 days!

However, Xiang Qianjin's present status is really too bad. Xiang Qianjin's family situation is not optimistic. My mother died before I went to college. My father used to be a researcher. He was a secret research project. Unfortunately, he died, leaving his three sons and his mother alone. My mother is also a graduate student. She lives on her little salary and her father's pension and salary. This money, raised three sons, big brother Xiang Qianchong, second brother Xiang qianyong, third is him, Xiang Qianjin. The elder brother went to the police academy and became a policeman. The second brother worked in a factory, and he was the only one who went to university.

The three brothers have a very good relationship. Xiang Jin's tuition is provided by the elder brother and the second brother. In fact, if he finds a job now, it can also ease the situation at home. He remembers that if he had been financially independent earlier, he would have been able to relieve the pressure on the elder brother and the second brother, who might not have gone the way of the future.

Xiang Qianjin was walking along the corridor of the teaching building when someone stopped him.

"Forward? You're not in the lab. what are you doing? "

Xiang Qianjin was excited. He looked up and saw an old man looking at himself. At this glance, all of a sudden to break the fog forward, it seems that... The opportunity has really come!

Xiang Qianjin went up without hesitation, helped the old man take over the information and said, "Mr. Zheng! Ha ha, I have something to ask you. "

"Oh! What's the matter? " Zheng looked at Xiang Qianjin suspiciously. Xiang Qianjin said with a smile: "well, Zheng, I have an idea. Isn't this an internship in the scientific research room? I have an idea, but Cheng Zhi doesn't listen to other people's opinions, and I don't want to discuss it with him. I want to ask you. After all, if you are a teacher, he will belittle others. "

"Well, if you have any problems with Cheng Zhi, you should quit his R & D team first, and I'll give you a piece of news quietly! Our school will have a project soon. I value you, boy Mr. Zheng said this with a mysterious smile. Xiang Qianjin of course knows what Mr. Zheng said about the project, that is, the DC electric control design project of large-scale equipment presided over by Mr. Wang. Xiang Qianjin will push this project to the climax. Xiang Qianjin said with a smile: "I'm not saying bad things about him to you. I really have ideas. I want to discuss with you."

Mr. Zheng smiles. He looks at Xiang Qianjin and asks, "OK! In that case, let's go to the classroom over there and have a talk! "

Mr. Zheng took Xiang Qianjin into a classroom that was not used for the time being. He turned to Xiang Qianjin and asked, "OK, what do you think! Let me hear what you think. "

Mr. Zheng is such a person. He likes to listen to young people's ideas. He will encourage you to do it even if it is unconstrained. Moreover, if your idea can work in theory and reality, Mr. Zheng will help you realize your idea. Therefore, this is definitely the breakthrough point to break the biggest obstacle for the project! First of all, we should get Zheng's approval.

Thinking of this, Xiang Qianjin explained: "we are now developing a new generation of batteries. They want to continue to upgrade from NiMH batteries. I don't think it will work. No matter how to upgrade NiMH batteries, they won't be able to match the natural advantages of lithium batteries. After all, we are developing mobile phone batteries, not large batteries. "

Zheng Lao looked at Xiang Qian suspiciously and asked: "Oh?! You say natural advantage? What's the advantage? "

Xiang Qianjin confidently replied: "well, the operation of Ni MH battery has a" memory effect ". The so-called memory effect is that the battery needs to be continuously charged for 12 to 14 hours. The life of continuous charging is about 500 times. However, the effect of lithium-ion batteries is different. Now CHONGYING has launched lithium-ion batteries. They use a polymer material called "lithium iron phosphate". This polymer material has a relatively stable olivine lattice structure, fast charging speed, long life and excellent stability. The only bad thing is that it does not work well at low temperature. But we can do something else. The problem of poor working at low temperature can be solved through the solution of external materials. "

These things are common sense problems in some popular science materials for Xiang Qianjin. For him, it is no longer necessary to prove whether it is reasonable. In the research and development of DC power, there is a great progress in battery research. So in terms of batteries, Xiang Jin is an expert.

Zheng was slightly stunned. He took a deep breath and carefully thought about what Xiang Qianjin said. After a long time, he said in a low voice: "do you mean that you want to use lithium-ion batteries made of polymeric materials? Do you know about polymer materials for lithium ion batteries? "Xiang Qianjin looked around. He looked back and saw a blackboard behind him. Then he picked up the chalk confidently and brushed on the blackboard to write a lot of chemical formulas.

Charging state: LiFePO4 XLI (lithium ion) - Xe → xfepo4 + X (1-x) LiFePO4

Discharge state: FePO4 + XLI + Xe → xlifepo4 + 1-x FePO4

Cathode reaction: LiFePO4 ↔ Li1-xFePO4 + xLi+ + xe- ；

Negative reaction: XLI + + XE - + 6C ↔ LixC6；

The total reaction formula is LiFePO4 + 6xc ↔ Li1-xFePO4+LixC6。

After Xiang Qianjin finished his last stroke, he clapped his hands and turned his head and said, "Mr. Zheng, do you think this is a problem?"

Mr. Zheng stood up and looked at the equation suspiciously. Then he looked at Xiang Qianjin and said, "where did you learn that? Don't you... Major in electronic control? "

Xiang Qianjin said with a smile: "such a basic thing, as long as you use some heart, you can understand it!"

Zheng picked up the presbyopic glasses and studied on the blackboard in surprise. He looked at the things on the blackboard like a ghost. He kept looking and thinking. At last, Zheng took off his eyes and nodded. He was puzzled and asked: "go ahead! You tell me the truth, you made it all by yourself? "

"Well, yes, I have all the supporting plans for the production process." Xiang Qian confidently straightens his chest. Zheng Lao points to Xiang Qian and says: "really?! You mean, can you come up with a whole plan right now? "

"I can try, but I'm not sure, so I'm looking for you. I'm a scientific and technological personnel. Although I haven't graduated yet, I should have professional ethics now. I'm responsible for what I say, so what I want to tell you is that I can do it. "

Mr. Zheng nodded. He frowned and thought for half a day. Then he said, "in this way, if you go to the office with me, you don't go to the research room in the afternoon. Come up with a plan as soon as possible. If you have any questions, you can ask me directly. " Zheng was obviously a little excited. Although he was not tall, when he grasped Xiang Qianjin's hand with his big thick hand, Xiang Qianjin felt that his hand was very thick and warm. And reliable

Zheng is always a good man, but he doesn't have a good eye and looks at the wrong person. He married his granddaughter to Cheng Zhi, but Cheng Zhi was a scum. In the end, when she gave birth to a girl, she took poison and killed herself. This matter to Zheng Laoqi disease, not long passed away. He still remembers this. This old man is really a good man. Unfortunately, good people are always bullied by evil people.

Xiang Qianjin smiles and helps Mr. Zheng take the information to his office. There is an electric stove in Mr. Zheng's office. The room is warmer than the scientific research room. Xiang Qianjin sits in front of his desk and writes his plan calmly. Does Zheng Qiaomin pour hot water for Xiang Qianjin, then look at his plan at any time and constantly give him suggestions. Unlike Cheng Zhi, Cheng Zhi will step on others, but Zheng is not. Mr. Zheng likes to explore, even if he is facing a college student.

After Xiang Qianjin finished all the plans, Zheng looked at them excitedly. He watched them for an hour, almost word by word! For an hour, Mr. Zheng didn't say a word, and he took the data from time to time for comparison. Finally, after reading all of them, Mr. Zheng's excited eyes were red. God bless the country! Unexpectedly... Unexpectedly out of you such a talent! Ha ha ha! forward! Do you know what your plan stands for? Your plan represents the future! Let us in the battery industry, if these ideas can really pass the laboratory, at least we have caught up with the pace of the world! Good boy!! Good boy!!! Ha ha ha!! You've reduced our generation gap by at least 15 years! "

"Yes? My plan? " Xiang Qianjin asked curiously, and Zheng praised: "if I didn't see it with my own eyes, it was you who wrote it, or if I didn't discuss it with you personally, I can't believe it was you who wrote it! This scheme is too sophisticated. I can hardly find any problems in details! You think of almost all the production and possible details. It's not like a research and development plan, but it's like a design description of production! "

At this point, Zheng's excited face turned red, and his face was full of red light. He is really happy, Xiang Jin is just a smirk. Although he was happy, there was something else in Xiang Qianjin's mind that might make Zheng angry. That is... To join Huacheng scientific research.

Dong Dong!

When Zheng Laohe Xiangqian was immersed in the joy of success, Sun Jin knocked on the door and said, "go ahead! Why are you here? No! Cheng Zhi, he said that you were maliciously absent from school, so he reported it. It has been sent to the director of instruction! "Mr. Zheng pulled his face and said, "what? Go ahead, have you asked for leave? "

"Please Xiang Qianjin said blankly, and Sun Jin testified and said, "I testify, please go forward. Cheng Zhi agreed, and then he did it! "

"This man, I don't think he's a good young man. He has a bad mind." Zheng old gloomy face, if do project malicious absenteeism was caught, in the future the way forward is finished, because there will be punishment, and many projects will not let him on.

The general teacher will not say anything to the students who are really absent from class two or three times. As a result, they all ask for leave. It's too much for him to say so!

After thinking about it, Zheng pointed to Sun Jin and said, "where is Cheng Zhi? Take me to him
