He sometimes wonders whether to modify the No. [-] system and install it in the mobile phone, but he finally gave up.
One is that the workload of the code is too large, and the other is that he is a little worried about handing over the source code. This intelligent system will be used in intelligent driving in the future. If someone takes advantage of it, it will be a great fun.
Qingshi, we can only do so much about mobile phones for the time being. The future science and technology laboratory needs a lot of talents. No play.
I know that during this period of time, Huaqing and the Chinese Academy of Sciences helped interview some people. By the end of the month, 106 people had arrived, and at least they were all PhDs who had worked for three or four years. This should relieve the pressure.
Luo Qingshi also has a headache about this matter, Dr. Xia Guoque?
There must be no shortage, 5 to 6 graduates every year, but there are really not many who meet Chen Nuo's requirements, and they still have to compete with so many large companies across the country.
There are too many factors that affect a person's choice, such as region, city, family, feelings and so on.
For those who have worked hard for 20 years, settled down and dragged their families, it may not be that courageous to let them give up what they are now.
Just keep an eye on this matter. We have solved several major problems of lithium-sulfur batteries. If everything goes well, samples will be produced at the end of the month, and a press conference will be held at that time. This will help you recruit people!
sample?So fast?
Luo Qingshi, who has always been prudent, was also surprised at this meeting. Although she doesn't understand technology, she has read the project document for the laboratory project, and the difficulty is not ordinary.
Samples were released in less than a month, this speed is too scary.
After chatting with Luo Qingshi for a while, Chen Nuo went to the fourth floor, found Lao Ying and others, checked the progress of some Sky Eye systems, and answered some of the questions.
One morning passed like this, and when it was time to eat at noon, the eagle said: Boss, those people who failed the test of the Xuanwu project team last year want to come back, you see?
According to the process, as long as the technology meets the requirements, you and Mr. Luo will ask for instructions. In addition, you need to recruit ten times and twenty times the number of people. You will not only work on the Sky Eye system, but also other projects on the Internet of Everything, otherwise the city brain will be a mess. empty talk.
clear!
After arranging these, Chen Nuo returned to the Future Science and Technology Laboratory and continued to fish.
In addition to returning to school in the middle to determine the topics for several doctoral students, he will look at the experimental results in the future science and technology experiments, and study the Ge Guess, Hodge Conjecture, etc.
Life is also relaxed and contented.
Until the twentieth day, Zhang Yueqi and Shen Yuanxing came hand in hand, interrupting the tranquility.
Looking at the excited two people, Chen Nuo's heart moved: Did all the experiments succeed?
Yes, we're starting to assemble it now, would you like to take a look?
go!
The three arrived at the assembly experiment, and several professors were doing the assembly.
Fifteen steps including negative electrode homogenization, positive electrode homogenization, coating, rolling, slitting, baking, winding, shelling, spot welding, baking, liquid injection, cap welding, cleaning, drying, and alignment inspection.
It has to be said that several professors of energy science are veterans, and it is more slippery to call it a day at this step.
Professor Chen, the last step is formation, do you want to try it?
Forget it, let's do it together, look at other people's eyes will pop out!
Everyone laughed, and several professors began to form.
The transformation is to charge the assembled battery, activate the active materials of the positive and negative electrodes, and let the battery have the process of discharging and charging.
Only after this step of formation can the battery be used.
This process only takes a few minutes.
That's it!
Chen Nuo was also a little excited when he saw that there was a simple battery block with a volume of only 10*10*8cm in front of him.
It is not necessary for the experimental product to be so large.
It is estimated that no one will notice this thing if it is thrown on the road, it is too inconspicuous.
Do the OCV test and see the final result!
Chapter 273 Surprise?frightened
Minister Zhou, are you busy? If you are not busy, come to our laboratory to give guidance!
Chen Nuo called Zhou Zhengfeng.
Nonsense, you are full of top professors, what can I guide?
Zhou Zhengfeng replied angrily: I have something to say, I'm busy!
Well, I wanted to share some good news with you, but you didn't appreciate it, so forget it, keep busy!
After Chen Nuo finished speaking, he immediately hung up the phone.
Listening to the busy tone coming from the phone, Zhou Zhengfeng shook his head, and said to himself: What good news can you have for this kid!
Just when he picked up the materials and was about to continue working, Zhou Zhengfeng froze for a moment, as if he remembered something.
Is it a breakthrough in new energy battery technology?
Zhou Zhengfeng had this guess, then he stood up and shouted outside: "Xiao Li, prepare the car!"
A few minutes later, the car was driving on the road leading to the future technology laboratory. Looking at the congested road, he frowned.
What is this old man doing, why is the progress so slow?
Minister, this is fast. I heard from friends in the traffic control department that their plan is to gradually remodel from the outside of the fifth ring road to the center of the city. The traffic lights in the center area are dense and the traffic is heavy. If something goes wrong during the renovation process, it will be bad. .
The second is to test the system, collect data, and optimize during the modification process. It is estimated that it will be in mid-June here!
Hey, thinking about the final result mentioned by Professor Chen, I have some expectations.
While waiting, Zhou Zhengfeng arrived at the Future Technology Laboratory. After four or five verifications, he finally reached the first floor.
Minister Zhou, Professor Chen asked me to wait for you here!
As soon as he entered the door, Yang Song, Chen Nuo's assistant, greeted him.
this kid!
Zhou Zhengfeng gave a low laugh, and followed Yang Song to the laboratory where Chen Nuo and others were.
Minister Zhou, you are here!
Everyone greeted each other one after another, Chen Nuo looked back at Zhou Zhengfeng and grinned.
What are you doing?Why are you staring at this brick?
When everyone heard Zhou Zhengfeng's words, they couldn't laugh or cry.
Lithium-sulfur batteries are bricks, but are they okay?
Minister Zhou, here is a sample of a lithium-sulfur battery!
Zhou Zhengfeng was stunned by Shen Yuanxing's words.
Lithium sulfur battery?Zhou Zhengfeng was stunned for a moment: What a fool, I made a lithium-sulfur battery in a month, do you think I look like a fool?
Professor Chen, even if you're trying to make me happy, don't joke about it!
Do you think I'm idle?
Chen Nuo stared at the lithium-sulfur battery sample being tested, and replied without looking back.
Looking at the expectant eyes of the other professors, Zhou Zhengfeng said to Shen Yuanxing: Professor Shen, is this true?
Really, truer than real gold!
Shen Yuanxing became excited when he said this: During this period of time, we have done a lot of experiments and solved the problems of positive electrode activity, shuttle effect, lithium dendrites, etc. After solving these problems, lithium-sulfur batteries will naturally be made.
it's done it's done
Only these four words echoed in Zhou Zhengfeng's mind.
When Chen Nuokeng asked for 6 million yuan, he thought that Chen Nuo would definitely be able to break through some technical limitations.
But which type of battery Chen Nuo was researching, he asked several times, but Chen Nuo kept it a secret.
He thought it was one of the ternary lithium battery, lead-acid battery, lithium manganese oxide battery or lithium iron phosphate battery, but he didn't expect this kid to be Wang Zha.
Zhou Zhengfeng was in a daze, no one laughed at him.
If they were not involved, someone told them to solve the lithium-sulfur battery in a month, and he would think that the person who told him was crazy.
Professor Chen, it has been calculated that the current energy density is 1816Wh/kg, which is 8.25 times that of the lithium iron phosphate battery announced by LG Chem, and 9 times that of the currently known ternary lithium battery.
Only 1800?It's a little low!
Chen Nuo frowned, apparently dissatisfied with this value.
The theoretical energy density of lithium-sulfur batteries is 2600Wh/kg, and the current one is less than 70% of the theoretical one.
Although everyone was used to Chen Nuo's monsters, but now hearing his dissatisfaction, they still wanted to curse.
Professor Chen, it’s not too low. This density can beat any battery in the world.
That's right, the ternary lithium battery was just over 60 Wh/kg when it was first made, but after decades of development, it is now only 180Wh/kg, which is already a very high starting point.
Give us a year or two, and it will not be a problem for the energy density to reach more than 2200.
Yes, even if it reaches 2600 km, the above will not allow it to do so. For ordinary new energy vehicles, I think it is very good to have a battery life of 1500-2000km, which is enough for us!
Everyone was expressing their opinions in one go, and Zhou Zhengfeng was awakened by the sound of discussion.
I seem to have heard 1800 just now?What 1800?
Minister Zhou, it is the energy density of lithium-sulfur batteries!
hiss!
Zhou Zhengfeng, who had just woken up, started his fugue state again.
Forget it, let's do this first, and leave it to the newcomers to practice!
Everyone rolled their eyes in unison again.
Everyone, in the 70-meter race, we have already run [-] meters, and we will do a violent test next, and the safety issue is the most important.
Internal short circuit test, continuous charging test, overcharge drop test, penetration test, heat abuse test, water immersion test, burning test, high voltage test, baking test, electronic furnace test, etc. Do it over fifty times!
Chen Nuo talked about 17 battery testing methods in a row.
Everyone's face was serious, this kind of test is very necessary.
The energy density of lithium-sulfur batteries is too high, even if it is reduced to 5 times, if something goes wrong, it will be a bomb, and the people in the car will have no chance to escape.
As for the electric vehicle battery management system, Chen Nuo did not mention it. All major car companies have very mature systems, and it would be a waste for him to do another one.
Professor Zhang, take someone to sort it out from the beginning to see if there is any optimization, and calculate the cost by the way.
Professor Shen, you take people to do safety test experiments, to see the charging time and so on.
Professor Qi, take someone to sort out the production process of each link of the battery, etc.!
I want accurate results within three days, is there a problem?
After the three professors clicked responded, they each left with some people.
Minister Zhou, how about this surprise?
At this time, Zhou Zhengfeng finally had a chance to intervene. Hearing Chen Nuo's words, he sighed secretly.
Completely change the problem of travel, sweep the battery and new energy vehicle markets all over the world, and change the structure of the automobile market.
Xiaguo's carbon peak may be advanced one to two years, which will save trillions of funds.
This isn't a surprise at all, it's a complete shock.
Fortunately, he didn't have a heart attack, otherwise today's surprise would probably send him away directly.
You boy is such a monster!
Thousands of words came to his lips, but they became such a sentence.
Chapter 274 Old Zhou, You Are Not Real
Chen Nuo, tell me about lithium-sulfur batteries in detail!
In Chen Nuo's office, Zhou Zhengfeng looked serious.
The matter is so important that he cannot be careless.
