Chapter 38

In the morning, Xiang Qian came to the city library alone. Continue to look for some information about the production line finalization. There are some in these libraries. Many enterprises will collect the information and send it to the municipal library for other R & D enterprises as research materials.

Although Huayan is a private scientific research and design enterprise, R & D is also something that can benefit the people. If the mobile phone battery can be promoted, at least the domestic people will not need to be so tangled with the battery, charging and using, instead of the original way.

Xiang Qianjin knows his own direction. If he goes out, it is very likely that he can really improve the pattern of domestic products. Although it is only a small step, it is also a big step in the foundation. If this step is taken and the production is completed, many mobile phone manufacturers can do it through this aspect.

He began to work hard to find production cases and some common problems in battery production. It seems that the domestic data can not be increased, so Xiang Qianjin decided to look at the foreign data, maybe there is some useful information in it!

However, the materials are written in foreign languages, which countries have, but most of them are in English, and most of the publications are in white eagle and Huangjia. At present, the development of science and technology is mainly around their branch lines. In addition, there are many books about CHONGYING.

Xiang Qianjin didn't think so much about it. Hurry to learn. He knows English and often reads it, but CHONGYING seldom reads it and doesn't understand it. However, with the system in place, everything seems to be easy. You can take everything and see it.

Not only can you understand it, just like reading Chinese, you can understand its implied meaning.

In the library, there are many people who brush the questions. Many graduate students are seriously brushing the questions in the library. Opposite Xiang Qian, there is a beautiful girl. She is wearing a white down jacket and a single ponytail. She sits at the desk reading with a serious face. Before long, a man in a black windbreaker comes over, He said with a smile: "Yuhan, what a coincidence, you are also reading here?"

"Well, I'm looking for books on my subject."

"If you have any questions, you can ask me. My family bought a computer, and it's much faster to find out."

Xiang Jin is too lazy to pay attention to him. What are you doing here with a computer? Showing off? Young man, you can, you don't even have a red face?

When Xiang Qianjin was holding a Russian book "modern industrial dry battery manufacturing case", the girl glanced at it and saw the book in Xiang Qianjin's hand. Is it a pure Russian book? Xiang Qianjin flipped through the book quickly. He didn't know that there was a girl watching him. Not long after Xiang Qianjin read it, he began to look for some white hawk and royal science magazines to find some relevant information. The man glanced forward and hummed coldly: "if you don't understand, you can still pretend."

Xiang Qianjin just put down a book. He glanced at the man. He looked very young, and he was about the same age as Xiang Qianjin. He glanced forward at the other person, then continued to read as if he were the air.

Bullshit, where have time to talk to him? Before long, Xiang Qianjin has finished reading all the books in front of him. Originally, he intended to see if there are any useful experiences and actual production cases, but what he didn't expect is that these materials are real antiques. In Xiang Qianjin, there is nothing to learn from! I can read it as a history book

Xiang Qianjin sighed and said in a low voice: "the books in the library are too shallow. There is nothing I want at all..."

The young people who listen to this sentence are stunned. Are there not enough books in the city library? Too shallow? Can you die without pretending? It's a science and technology magazine with white hawk in the left hand and a technology weekly with heavy cherry in the right hand. It's the last one with 99 beep index. I'm afraid you're proud!

However, Xiang Qianjin didn't bother to pay attention to him at all and continued to get professional books. The girl noticed a problem. Xiang Qianjin was always looking for something in professional books. He basically didn't go to other places to read. At present, Xiang Qianjin is looking for science and technology books, and they are all the latest technology. He read the magazine carefully. After reading it for a while, he always had a bitter smile on his face. It was like a college student reading a popular science book with great interest. It turned out that it was a natural feeling in primary school

Moreover, if Xiang Qianjin could not understand it, he would not have chosen it so carefully. He was obviously looking for professional books, Moreover, he was very careful when selecting books. Some books were turned over on the shelf and put back. Some books will stay, which is definitely not pretending to understand. It seems that this person should be a scientific researcher. Xiang Qianjin can't care about the beauty at this time. Read a book! The ocean of knowledge has completely isolated him from the world. Besides, Lin Kexin and Liu Ruoxin shake in front of him every day. They are immune to the so-called beauties. Xueba doesn't need to pay attention to beauties!At present, Xiang Qianjin doesn't want to do anything but brush the book... He brushes crazily, like he is vowing to eat science and technology to the end. When Xiang Qianjin looks at the book, the girl takes her book and asks, "Meng Yang, look at this topic, the topic of lithium-ion battery, look at it."

Meng Yang suspiciously took this question, and then said: "lithium ion battery? Let me see! Isn't lithium battery made of metal? Yuhan, why do you choose such a difficult subject? Crazy you! You have to wait until you go abroad. My father said that it will help us go abroad. Who in China can know this? "

Xiang Qianjin, like an old monk, calmly replied: "lithium ion battery was first developed by a company of CHONGYING in 1990. The company embeds lithium ions into carbon to form negative electrodes, while traditional lithium batteries use lithium or lithium alloys as negative electrodes. LixCoO2, lixnio2 and lixmno4 are commonly used as cathode materials, and LiPF6 + ethylene carbonate (EC) + dimethyl carbonate (DMC) is used as electrolyte. He uses petroleum coke and graphite as anode materials, which are non-toxic and abundant in resources. After lithium ion is embedded in carbon, it overcomes the high activity of lithium and solves the safety problem of traditional lithium battery. LixCoO2 cathode can achieve a high level in charge and discharge performance and life, which reduces the cost. In a word, the comprehensive performance of lithium-ion battery is improved. As for the reaction formula of lithium-ion secondary battery during charging and discharging, it should be "LiCoO2 + C = Li1-xCoO2 + lixc"

"Are you a battery professional?" The girl was surprised to open and press the item to move forward. In fact, the item to move forward was just a casual remark. As a result, the other party picked up the fault. He was stunned and looked around. Then he pointed to himself and said, "me?"

The girl nodded, and she said with a smile, "Well! Hello, I'm Zhou Yuhan from the University of technology. Who are you... "

"Oh! Hello! I'm a student in the R & D Department of HKUST. My name is Xiang Qianjin. I'm studying on the job. "

"Go ahead? Ha ha, this name is interesting! Are you developing lithium batteries? Are we still neighbors? " Zhou Yuhan looked forward with excited feeling on his face.

Xiang Qianjin nodded and said, "well, I'm participating in a lithium battery research and development project. This is not a collection of materials to tackle the research and development of a new generation of lithium batteries. Now we have to come up with a plan. Unfortunately, there are only so many materials in the library. There is nothing useful at all. "

"Research and development of HKUST? Can you talk about it? I remember that there is a Zheng Qiaomin in your university of science and technology. He is an expert Zhou Yuhan's eyes are shining and he looks at Xiang Qianjin. Because he is an alumni next door, his relationship can be closer from the emotional point of view.

However item forward swept the Meng Yang beside one eye, he was very displeased of hum a. Then he said, "I think he is an ordinary college student. He can know a fart! Those who are still engaged in scientific research are still working and studying. Listen to him! Besides, domestic scientific research is useless! Going abroad is the right way. And I won't be able to enter the Graduate School in the future, will I? Hum, a guy who can't even get into the research institute is still blowing here? Civil Science in China? What a joke
