Rebirth of the Tech Frenzy

When I got up in the morning, Xiang Qiang came to the city library alone. Continue to look for some materials related to the production line stereotyped production. There are some in these libraries. Many companies will collect the materials and send them to the city library to use as research materials for other R&D companies.

Although Huayan is a private research and design enterprise, research and development is also a real thing that can benefit the people. If the mobile phone battery can be promoted, at least the domestic people don't need to be so entangled with the battery, just charge it and use it instead of the original.

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

The deep innocence gave him the energy to struggle. He began to work hard to find production cases related to batteries and some common problems in production. There seems to be little growth in the domestic materials, so Xiang Qianjin decided to look at the foreign materials, there may be some useful information in it!

It's just that the texts of those materials are in foreign languages, which are available in any country, but most of them are in English. Most of the publications are White Eagle and Royal. At present, the development of science and technology mainly revolves around the branches developed by them, and the other is Chongying, and there are many books on Chongying.

Xiang Qianjin didn't think so much, so he hurried to learn. He understood English and read it often, but Zhongyingwen rarely read or understood. But after the system is in place, everything seems to be easy, and everything is taken over and seen.

Not only can you understand it, it's the same as reading Chinese, and you can see the implicit meaning clearly.

In the library, there are a lot of people writing questions. Many graduate students are working hard in the library. Opposite Xiang Qianjin sat a beautiful girl who was wearing a white down jacket and a single ponytail. She was sitting at the table reading a book seriously, and soon another man in a black trench coat came over and said with a smile: "Yuhan, what a coincidence, are you reading here too?"

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

"If you have any questions, you can ask me. I bought a computer and found it much faster."

Xiang Qianjin doesn't bother to talk to him. Why are you running here if you have a computer? Show off? Young man, you can do it, but the girl who doesn't blush when she picks up girls?

When Xiang Qianjin was holding a Russian copy of "Modern Industrial Dry Battery Manufacturing Cases", the girl glanced, and she saw the book in Xiang Qianjin's hand at a glance. Is it a book in pure Russian? Xiang Qianjin flipped through the book quickly. He didn't know that there was a girl looking at him. After a short time, after Xiang Qianjin read it, he began to search for some White Eagle and Royal Science magazines, and found some related information. data of. The man glanced at Xiang Qianjin and snorted coldly: "If you don't understand, you can still pretend."

Xiang Qianjin just put down the book. He glanced at the man. The man looked quite young, and he seemed to be about the same age as Xiang Qianjin. He glanced forward at the other person, and then continued reading as if he were air.

Nonsense, where can I take care of him? It didn’t take long before Xiang Qianjin read all the books in front of him. With such a large number of books, I originally planned to see if there are any useful experience and actual production cases, but no What I think of is that these materials are really old antiques, and there is nothing to learn from Xiang Qianjin at all! It can be read as a history book...

Xiang Qianjin sighed and whispered, "The books in the library are too shallow, and there is nothing I want..."

The young man who heard this sentence was taken aback, and the city library didn’t have enough books to read? Too shallow? Can you die if you don't pretend? This made him pretend to be the science and technology magazine of Baiying in the left hand and the technical weekly magazine of Shigeo in the right. The pretending to be the last 1 score of 99 is afraid of you being proud!

However, Xiang Qianjin didn't bother to talk to him at all and continued to get professional books. The girl noticed a problem. Xiang Qianjin had been looking for things in professional books, and he basically didn't go to other places to read. At present, Xiang Qiang is specifically looking for science and technology books, and they are all the latest science and technology. He flipped through the magazine and looked at it seriously. After reading it for a while, he always had a helpless smile on his face. It was like a college student reading a general undergraduate book with great interest, and he found that it was a natural elementary school feeling...

And if Xiang Qianjin couldn’t understand, he couldn’t pick it so carefully. He was obviously looking for professional books, and he was very serious when choosing books. Some books were turned over on the shelf and put them back. Up. Some books will stay. This is definitely not pretending to understand. It seems that this person should be a scientific researcher. How can Xiang Qianjin take care of some big beauties at this time~www.readwn.com~! The ocean of knowledge has completely isolated him from the world. Besides, Lin Kexin and Liu Ruoxin are shaking in front of him every day. They have long been immune to the so-called beauties. Xueba doesn't need to pay attention to beauties!

Right now Xiang Qiang didn’t want to think about anything, just brushing the book... Crazy brushing, swearing to eat science and technology to the end, when Xiang Qiang was reading the book, the girl took her own book and asked: "Meng Yang, look at this. Questions, the subject of lithium-ion batteries, take a look."

Meng Yang took this question suspiciously, and then said: "Lithium-ion battery? Let me think about it! Isn't lithium battery metal? Yuhan why did you choose such a difficult subject? Crazy you! This technology you I have to wait until we go abroad. My dad said that he will definitely help us go abroad. Who can know this in China?"

Xiang Qianjin was like an old monk who had entered Ding, and replied calmly: "Lithium-ion batteries were first developed by a company in Chongying in 1990. This company embeds lithium ions into carbon to form a negative electrode, while traditional lithium The battery uses lithium or lithium alloy as the negative electrode. LixCoO2 is commonly used as the cathode material, and LixNiO2 and LixMnO4 are also used. The electrolyte uses LiPF6 + diethylene carbonate (EC) + dimethyl carbonate (DMC). His carbon is petroleum coke and graphite As a negative electrode material, this material is non-toxic and has sufficient resources. After lithium ions are embedded in carbon, it overcomes the high activity of lithium and solves the safety problems of traditional lithium batteries. The positive electrode LixCoO2 is in charge and discharge performance and life. Both can reach a higher level, reduce the cost, and improve the overall performance of lithium-ion batteries. As for the reaction formula of lithium-ion secondary batteries when charging and discharging should be "LiCoO2+C=Li1-xCoO2+LixC". "

"Are you a battery professional?" The girl was surprised to open and press Xiang Qiang, Xiang Qiang actually just said casually. As a result, the other party got stubborn, and he also looked around in a daze and then pointed to himself and said: "Me? "

The girl nodded, and she smiled and said: "Hmm! Hello, this is Zhou Yuhan from the University of Engineering Science, may I ask if you are..."

"Oh! Hello! I am a student in the R&D room of the University of Science and Technology, and my name is Xiang Qianjin. I am now in the on-the-job study stage."

"Xiang Qianjin? Haha, the name is interesting! Are you developing lithium batteries? Are we still neighbors?" Zhou Yuhan looked at Xiang Qiang with excitement.

Xiang Qianjin nodded and said, "Well, I'm participating in a lithium battery research and development project. This is not collecting materials to tackle the new generation of lithium battery research and development. Now I have to come up with a plan. Unfortunately, this library only has so many materials. Nothing is useful at all."

"HKUST R&D? Can you talk about it? I remember that you have a Zheng Qiaomin at HKUST, Mr. Zheng, who is an expert!" Zhou Yuhan looked at Xiang Qiang with bright eyes, because it was an alumnus next door, the relationship could be closer in terms of affection. a little.

However, Xiang Qianjin glanced at Meng Yang next to him, and he snorted very uncomfortably. Then he said, "I think it's just an ordinary college student. He can know what a shit! He is still engaged in scientific research and is still studying on a job. Just listen to him! Besides, domestic scientific research has a shit! Going abroad is the right way. And you won’t be able to enter the research institute in the future, right? Huh, a guy who can’t even enter the research institute is still playing here? The domestic civil sciences? What a joke!"
