Black technology starts from the steel suit

Chapter 34 33 Yanda Energy Laboratory

He doesn't have time to deal with negotiations now. At this moment, he is in the No. 5 area of ​​Summer Palace Road, visiting their future workplace with Senior Brother Hua and his team in the two laboratories assigned to him by Yanda University.

It has to be said that Yanda is very generous in doing things. Not only did he allocate the laboratory to them without saying a word, but he also deployed a large number of personnel and equipment to establish the Yanda Energy Laboratory and hired him as a professor and as a laboratory director.

Although Yan University got a big share of this project, they paid for the site and personnel. The deputy director of the laboratory is a Maverick at the level of a Changjiang scholar, which greatly alleviated the problem of Wang Feng's shortage of personnel. On the one hand, Wang Feng is not at a loss. He has no intention of making any money from this national project, so the more people involved, the better.

As for the promise over there, he intends to use it as an academic capital to enhance his influence and voice in the academic world. Since he has some disadvantages in terms of age, he will use other things to make up for it!
So although there is no establishment, and they are working for the National Laboratory as temporary workers, the people under him are not at a disadvantage. The salary is all subsidized according to the standard of official research fellows of Yanda University, and they also receive what Wang Feng gave them. The salary and subsidies are simply blood money!
"Let me introduce to you first. This is Professor Liu Xuelin, the deputy director of our laboratory. Let's get to know each other first!" Wang Feng introduced to everyone.

"Hello Director Liu, I'm Hua An!"

"Professor Hua, Academician Liu's senior student, I've heard of you..." Professor Liu shook hands with Hua An without putting on airs and said, "I would like to congratulate you on being awarded the title of professor. Young people nowadays are more and more It's getting stronger!"

"Where is it..." Hua An said modestly, with an expression of "if you can talk, talk more".

"Professor Wang is the most powerful. You have been awarded the title of professor by Yanda University and the University of Science and Technology of China at the same time. I admit that I am an associate professor..." Brother Hua and Wang Feng have a good relationship, otherwise they wouldn't carelessly put the membership card in the consumption list Give it to him directly.

"It's just a false name, it's all a false name, hahaha!" Although Wang Feng is very useful, his expression still betrays himself: "Professor Liu has been rated as a Changjiang scholar at such a young age, and the future may be limitless!"

The meeting of the three of them was like a business meal, and they seemed very harmonious.

The academic circle is so small. At the top of the pyramid are academician-level big cows, or other top predators. In the middle are young people like Changjiang scholars. Everyone basically knows each other, no matter how bad they are, they also know their names.

After that, there are some more influential professors, as well as low-level scientific research bricklayers. The vast majority of people in this part do not have names.

Everyone: mmp!

It's okay, this pretense is too hard, and these trembling brickworkers can't take it.The title of professor at a university requires at least 7 years after graduation. This is still a smooth situation; if it is a professor at a top 10 university like University of Science and Technology of China or Yanda University, the difficulty may be even higher.

As for the Yangtze River Scholars... this is still far away from them, so it's worth not mentioning it.

Of course, there is something else to say about people like Wang Feng. This kind of guy with a superhuman IQ is not the same species as them at all; there is another kind of boss who is very powerful, like Brother Hua, who is also very capable, but he can jump so fast. To the associate professor level, in their eyes, he is still his former academician boss and current boss Niu!
Thinking about it this way, they suddenly felt that the future was brighter.

"Yeah, it saved me two or two years of struggle. Now that I think about it, I still find it unbelievable. So, Professor Wang, you should hurry up and tell us what our mission is. With such a strict political review, we 100 There are so many people, only 80 people are still standing here!"

Speaking of this, Hua An felt a little dreamy. They were able to enter Wang Feng's team through inspections. They had passed the test and investigation. Wang Feng himself might not know this, but the bodyguards around him knew it very well, but that's all. Brush down a large number of people.

"Okay, then let's have a good chat. You people in charge come over with me, and others can take a look here!" Speaking of business, Wang Feng also became serious.

Although the rest of the people looked at each other in blank dismay, they were somewhat nervous, but the relaxed tone of the chat between Associate Professor Hua and Professor Wang still played a role in diluting some of their nervousness.

"You are all able to sit here, which shows that both your personal conditions and wishes have met the requirements, so I won't go into details, and get straight to the point!"

"At present, there are two main research directions for us, and that is to further improve the safety and capacity of the l3 lithium battery so that it can meet the harsher environmental requirements and higher energy density requirements."

Although Wang Feng didn't say it clearly, everyone knows exactly what the harsher environmental requirements and higher energy density are aimed at. After all, only military missions will have such strict reviews!
"The first thing to put forward is the safety requirement. Everyone should be aware of this. After all, this is the most important problem to be solved in the promotion of lithium batteries. Although its safety is still very good, whether it is a puncture test or a collision, It can meet the requirements of destructive tests such as extrusion, or safety tests of a single battery out of control."

"But then we discovered a fatal flaw in it. This is a loophole in our security testing experiment. We must never do it again in the future!"

"What defect?"

"No way, we have done such a comprehensive test and tested it according to international standards. Are there any loopholes?"

"Ahem, facts speak louder than words, let me play a PPT for everyone!"

Everyone:!!!∑(Дノ)ノ

"What kind of shit is this!"

"I'll go, is this serious?"

"Hey, hey, we are making batteries, not bulletproof panels!"

"Isn't it too much for you to test the battery with explosives?"

"It's fine to use TNT, but you actually go directly to Hexokin, and it's a good thing that the total nitrogen compound has not yet entered the mass production stage!"

Although Wang Feng did not release the picture of the deflagration of the battery that was bombarded by shells, the picture of the battery pack being "bombarded" by explosives and then being pierced by the experimenter with a sharp object such as a blade still makes these averagely above the master's degree. A researcher with a degree is swearing!

"Ahem, cough, please don't get excited. After all, the buyers on the screen are not ordinary users. It is understandable that the usage requirements are stricter." Wang Feng can only appease his people first, otherwise, everyone will probably be able to complain all day. .

"Professor Wang, it's not that we are excited, but the shock resistance of the compacted material is just like that. Being swept by the shock wave will inevitably lead to the destruction of the material structure. This is determined by the characteristics of the material itself!"

"It is not impossible to increase the compaction density, but it will have to sacrifice battery performance. After all, if the density continues to increase, the ability of the negative electrode to deintercalate lithium will be greatly reduced, and the gain outweighs the gain."

"And this may not necessarily solve this problem. The shock wave of the explosion destroys the structure, and denser compression only adds some weight, and the strength improvement is very limited..."

Everyone is majoring in lithium batteries or materials science, and they are naturally familiar with these things, so everyone is so excited.

Professor Liu was also really shocked: the deputy director and the research funding are really hot!

"So we have to redesign the pretreatment of the carbon nanotubes according to the characteristics of the liC anode material. Maybe we have to consider not to slightly oxidize it."

"You mean starting with van der Waals force?"

Everyone understands Wang Feng's intention. Slight oxidation will reduce the aggregation degree of nanotubes, and at the same time reduce the binding ability of van der Waals force, so that lithium can be better deintercalated. This is an advantage in the past, but if military use is considered, this It becomes a disadvantage.

"So we need better technology to solve the problem that the aggregation of carbon nanotubes affects the efficiency of lithium deintercalation. If we do not perform oxidation treatment, how can we solve the problem of poor dispersion."

"My opinion is to start with the treatment method. Since covalent modification will affect its structural stability, then we should start with non-covalent modification or even inorganic coating to consider the solution!"

"Personally, I am more optimistic about inorganic coating. After all, the most prominent issue is structural safety issues, and we also have considerable experience in vapor deposition methods for reference. This is the second."

"Then what should we do about the energy loss caused by this?" Brother Hua asked curiously.

"This is the last point I want to say. We will cooperate with BYD's blade battery R&D team to jointly develop blade-type l3 series batteries, so as to make up for the energy loss of the negative electrode mixed with the coating material."

"Blade battery?"

The people present looked at each other in blank dismay. They were all professionals in the industry. Naturally, they knew very well the principle of the blade battery. It was because of their understanding that they seemed confused.

"The battery pack space utilization rate of our square L3 battery has reached 50%. Is it necessary to use BYD's technology?"

"Yeah, it's not necessary, our technology is not much worse than theirs!"

Unlike natural science, which directly benefits all mankind, this kind of science that involves practical application is related to the distribution of benefits. The most practical thing is patent rights. In the horizontal project of cooperation with enterprises, Yanda Energy Storage The laboratory can enjoy 30% of the results. Wang Feng doesn't care about this part, but they do!
"The answer is that it is necessary. We should cherish any opportunity to increase the capacity of the battery without adding too much cost. I mean the cost of materials and the cost of manufacturing."

Wang Feng's words can be regarded as the final word. He is the person in charge of the laboratory, the leader, and other people have no right to refute what he has decided.
