After a thousand years of trading, start a million barrels of oil

Chapter 125 This Is Excellent?

Everyone looked at Director Jiang introduced by Secretary Liu, who was only in his early 20s, and looked at each other for a moment.

It's not like they haven't seen young geniuses before, such as Wei Dongyi and Wei Shen from Imperial University.

The 49th and 50th International Mathematical Olympiad full score winners, Hua Luogeng gold medal winners, Chen Shiingshen gold medal winners, Lin Jiaqiao gold medal winners.

The world-class mathematics competition award, if he goes, others can only compete for the second place.

He entered Imperial University directly without taking an exam, and was called the 'Sweeping Monk of Imperial University'. He created a set of problem-solving methods that were simpler than the standard answers, and was called the 'Wei Method'.

A doctoral team studied a problem that had not been solved for 4 months, and asked Wei Shen for help, and quickly got the answer, which was verified to be completely correct.

People wanted to pay Wei Shen, but Wei Shen said it was too simple to pay.

But that kind of arrogance can only be produced by more than a billion people, and mathematics can be cultivated from an early age, but in specialized fields such as batteries, including electrochemistry, light contact may require at least a university, let alone three or four years. Industry dean.

But Secretary Liu said that he was the director, which made it really hard for them to accept for a while.

Everyone looked at Wei Qiang. At this moment, it must be Professor Wei who raised the question.

Professor Wei understood other people's thoughts, and it was hard for him to believe it, so he walked over and stood in front of Secretary Liu and said, "Secretary Liu Liu, did you make a mistake? He is a student of my friend Professor Zhu Sixue from Sichuan University. How could he be?" What about our boss?"

Secretary Liu just smiled lightly: "There is no mistake. We picked up the person after checking the information and photos. Director Jiang has no problem."

"Uh oh." Wei Qiang also knew that he was presumptuous to ask. He was a secretary, and he was the secretary of a high-level chief. How could he do such a thing as picking up the wrong person.

Even if I don't believe it anymore, I can only accept it now. I expected that they might be over 21 years old, or at least the same age as the leading experts, but they are just a [-]-year-old young man, and he is still a student of his friend at school. .

Hey, maybe it's the back waves of the Yangtze River.

Wei Qiang could only look at Jiang Fan with a little embarrassment and smiled, and at the same time stretched out his hand and said, "Director Jiang Jiang, hello."

A few minutes ago, I was patting someone on the shoulder as an elder, and I even forgot his name a few minutes ago.

"Professor Wei, hello." Jiang Fan also shook hands generously.

It took him a while to realize that it was exactly what he had guessed. No wonder, what Professor Wei talked about last time was power batteries, but it was just a coincidence.

The other experts and professors saw that Professor Wei had already approved it, and they couldn't say anything more if they had any doubts. They all looked at Jiang Fan, nodded and smiled.

The group then went upstairs together. Wei Qiang first took Jiang Fan to visit the research institute according to the procedure, including the organizational structure, staffing, research and development direction, etc., and introduced Jiang Fan while walking. Still following behind, out of politeness, it is also to see if the new director has any pointers.

When passing the testing room, Wei Qiang took Jiang Fan to stop and observe in front of a battery being tested.

The researcher who operated the test asked Wei Qiang about the negative electrode material yesterday, but none of their professors could answer that question.

After the researcher's test, the battery result did not meet the standard. He remembered that Professor Wei said that he would ask the new director tomorrow. He could not believe it when he called the young man "Director Jiang", but he was probably sure. This person is probably the Director Jiang that the professor mentioned.

So I just took this opportunity to raise the question, and said: "Professor Wei, Director Jiang, the same question as mentioned yesterday:

The current negative electrode materials are mostly carbon or silicon. When the battery is charged, lithium ions move from the positive electrode to the negative electrode and are fixed in these materials.

If carbon is used for the negative electrode, 6 carbon atoms are needed to accommodate one lithium atom, and the energy storage efficiency is low.

However, many countries and enterprises are now trying to increase the energy density of the 'carbon silicon anode' by adding silicon to the carbon anode, but the upper limit is only 300Wh/kg.

More research on solid-state battery companies is to use lithium metal directly in the negative electrode, which can not only increase the energy density to 500~600Wh/kg, but also reduce the weight of the battery.

However, after lithium metal is used in the negative electrode, the repeated expansion and contraction of the negative electrode material during the charging and discharging process will cause lithium to form dendrite crystals, which will lead to short circuits and even fires.

So there seems to be no good way to solve this problem, and it is also the reason why we have been adjusting the method but still fail to meet expectations. Is there any good way to solve it? "

After he finished speaking, he turned his attention to the two of them, mainly to the new Director Jiang. He really wanted to know what kind of ability this young man, who was ten years younger than him, could overwhelm all the experts. Professor, take the director's seat directly.

Not only him, Professor Wei and other professors are the ones who most want to know the answer.

Even this group of intellectuals who have always been arrogant and arrogant still have a kind of angry attitude in their hearts. Why should such a young man be our leader?Not even for reputation.

Jiang Fan didn't think too much about it. He was lucky. Fortunately, he asked young people to ask for knowledge patches on electrochemistry and batteries. Otherwise, he would be embarrassed if he didn't even understand the questions.

Now, Jiang Fan is clear about the key points and crux of the researcher's question, and then he looks for the solution in the knowledge patch, and finds it quickly.

Clearing his throat, he explained to the researcher: "The idea of ​​using lithium metal as the negative electrode is correct, the key lies in solving the problem of its expansion and contraction.

Alloys such as nickel-cobalt-manganese can be added to neutralize its expansion characteristics. To achieve this goal, it is necessary to have a quota for the ratio of these rare metals. Take a piece of paper and I will draw it for you. "

The researcher brought a piece of paper, and Jiang Fan listed more than a dozen metal and non-metal substances for him, and wrote down the amount and ratio of each, and explained the reason for this configuration from the perspective of chemical principles.

After hearing this, the researcher felt as if he could see the blue sky through the clouds and mist, which was amazing.

"Okay, I'll go and make it according to this." The researcher happily took Jiang Fan's paper and ran to the laboratory excitedly.

Wei Qiang and a few other professors also looked stunned after hearing the plan. How did this person come up with such an exquisite formula and the relationship between them?That's amazing, is he really the God of Electrochemistry?

All the experts and professors looked at Jiang Fan full of astonishment, but what followed was admiration. If this person has this kind of strength, he will have no problem being the director of the joint research institute.

Wei Qiang was also so surprised that he shook his head helplessly. This little classmate was really hiding something, and Professor Zhu didn't tell me anything.

Oh no, he said that this is an excellent student, but this can't be called excellent, it is not too much to call it outstanding or outstanding.

At least for the problem that was just solved easily, none of their so-called field experts and leading professors thought about it for a long time last night.

This old Zhu almost caused him an embarrassment, and he must ask him to treat him later to make up for it.

After visiting the research institute, everyone had a meal together at noon. After a short break in the afternoon, Wei Qiang held a weekly meeting with the participation of major experts and professors.

On the one hand, this meeting is to formally welcome Director Jiang, and on the other hand, it is also to discuss the strategy, direction and pace of recent research and development.

It's just that this time it's different from Professor Wei's acting as the host. Since Director Jiang is here, it's natural that Director Jiang will be the host.

Jiang Fan is not afraid to host this kind of strategic meeting. He hosted many such meetings when he was training as an executive in Shanchuan Mining.

Professor Wei first introduced the situation we are facing. The most important thing is the development progress. The information given above has solved all the core difficulties, but many small bottlenecks still hinder the rapid progress of the development progress.

The second is about the new car product that will be launched in a month from the special tear of the rival Masigram on the other side of the ocean.

It is said that the latest 4680 battery is to be loaded. The so-called 4680 battery is not a breakthrough in the technology of the battery itself.

4680 is just a synonym for size, which is a large cylindrical battery with a diameter of 46 mm and a height of 80 mm. The larger size increases the capacity. It has 21700 times more capacity than the currently used 5 battery.

That is to say, a car was originally equipped with 1000 batteries, and each battery had a capacity of 1 and a volume of 1. Now that the capacity of each battery is increased to 5, the energy density has not changed, so the volume has also become 5 times that of the original.

Originally, a car could carry 1000 cells, but because the volume of a single battery has become five times that of the original, it can only carry 5 cells.

The essence is to drink one cup of 500ml water cup or five cups of 100ml water cup, there is no essential difference in energy carrying.

The reason why it can increase battery life is because the efficiency of grouping is improved, and the reduction in number greatly reduces the difficulty of battery management and improves battery life.

Including its real black technology, that is, self-developed electrodeless ear technology, this design can greatly reduce internal resistance and heat generation, and greatly improve battery safety and service life.

Therefore, according to Professor Wei’s estimation, compared with the 4680% mileage increase of the first generation 16 this time, the mileage increase of this batch of products may reach 40%, that is, the general mileage may increase from 550 The multi-kilometer increase to nearly 800 kilometers will greatly impact the domestic electric vehicle market.

If this wave allows the other party to seize the opportunity and lose the market, even if a better battery technology is developed later, the other party can rely on the market itself to iterate faster, and a series of factors such as consumer brand awareness will form barriers for others , it is likely to be absolutely at a disadvantage in this round of new energy competition, and even be completely eliminated in the end.

When Professor Wei talked about the current situation, everyone looked very solemn. This is the current situation faced by their research institute and China's power battery and electric vehicle industry, but because the time is too tight, they have no good way to deal with it for the time being.

"Director Jiang, what do you think of this question?" Professor Wei asked Jiang Fan.
