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

Chapter 124 Is He About Him?

When Jiang Fan heard Zhang Feng's invitation, he had nothing to worry about if he had the patch, so he agreed.

For Wei Qiang's side, he mainly gathered some core personnel of the department, including the original chief scientists of several other companies at the same level as him, as well as some senior researchers.

"Old Wei, why did you ask us to come here? Do you have any new ideas?" A specially-appointed professor from Ningde, who is about the same age and qualifications as Wei Qiang, asked. He just led the team to break through an important project. The specific technique was called out by Wei Qiang.

"I called everyone here to tell you a piece of good news. The breakthrough of our power battery is coming soon." Wei Qiang couldn't hide his excitement when he spoke.

"Oh?" The participants were stunned when they heard the news. The experiment just failed today. It's only been a few hours. You said a breakthrough will be made soon?It's a bit of a joke.

Could it be that you have learned something from this failure?It's not right, we participated together, why didn't we see it.

Wei Qiang knew everyone's doubts, but he didn't explain, and asked his assistant to turn on the projector, and projected the data on the computer connected to the mobile hard disk on the projection screen.

Open a document on the general nature of the solution for all-solid-state batteries, look at everyone and say:

"The all-solid-state battery we have been developing has been unable to make a breakthrough, mainly due to the following two reasons:

1. High impedance, poor lithium conduction ability of solid electrolyte, low lithium ion conductivity.At the same time, the solid is in contact with the solid, and the contact is also poor.High internal resistance, resulting in particularly low efficiency of lithium ion internal transport;

2. During the cycle charging and discharging process, the physical contact will also deteriorate, so the life of the solid-state battery has yet to be resolved.

For these two problems, we have made many attempts, but there is still no good solution.

But if we add sulfide to it, the sulfide is a soft solid with good conduction performance, so it can enhance the performance of lithium conduction and solve the problem of physical contact at the same time? "

A group of professors looked at each other, and it was still the professor Ning De who said: "Sulphide is indeed one of the general ideas to solve solid-state batteries, and this includes us and is also being studied internationally.

However, sulfide itself is unstable, sensitive to air, and the manufacturing conditions are still very strict. These core problems are still unresolved. "

Other experts and professors also nodded after hearing this. The idea of ​​sulfide is not new, but these issues are the key.

Wei Qiang didn't panic, he pulled down the opened file, saw that it stopped somewhere, and said to the professors and researchers:

"The solution is here. As long as we add the alloy material mentioned in the article to the sulfide, and at the same time adjust its conduction structure as mentioned in the article, we can solve all the problems of sulfide stability, sensitivity, etc. Some Problems."

"Huh?" The eyes of the researchers all brightened. Although they haven't actually tried it yet, from the overview of their ideas, they faintly feel that this method is indeed completely different from the previous methods, as if they have opened up a new continent. Can do it.

Several professors, including the chief scientist Professor Ningde, also felt a sense of relief after seeing it. Yes, the sulfide is unstable, and it is not completely impossible.

As long as some conductive structural adjustments are made, and these alloys are adjusted in proportion to change the properties of the sulfide, the problem may really be solved.

"Where did you get this material?" Other professors asked Wei Qiang impatiently.

Wei Qiang said: "It was given by the superior. I asked him where it came from. It wasn't from the Jun party. He said it was given to us by a patriot after he got it."

"Patriots?" Everyone looked at each other in blank dismay. What kind of patriots can get such information?
Made from island countries and the United States?Not right, according to the conventional route of technological progress and the understanding of their current progress, they have made a 70% solid-state battery, which is considered a major breakthrough.

However, it is written in the information that the development of all-solid-state batteries can be realized, which is a bit big.

Gull state?Neither.Asan?Hehe~
Forget it, no matter how it got there, for a group of professors and scientists, nothing fascinates them more than technology itself.

So I didn't think about the source anymore, and hurriedly asked Wei Qiang to include these materials into the database of the research institute so that they could study them easily.

Wei Qiang was also anxious to study the details inside carefully, and he came to them just to tell them about this matter.

So there was no more ink, and the meeting was adjourned directly, and then the assistant found the data management personnel, and asked him to transfer the data to the internal database of the institute, and set the permissions so that different people can view the content with different permissions.

With these materials, in the past few days, everyone has even forgotten to eat and sleep, completely immersed in the joy of discovering the new world, and various researches, interpretations, discussions, and attempts are carried out all the time.

With the help of data, breakthroughs have been made in many specific technical aspects and experiments have been successful.

But after this wave of success, everyone encountered another problem. Although with these materials, the all-solid-state battery will eventually be able to break through, but the time may not be enough.

Competitors will launch electric vehicles equipped with new batteries soon, and it may not be a matter of time before they overcome and complete the uncompleted parts of the technical information provided.

In the past few days, I have encountered many small bottlenecks, including the participation of the professors and they still have no immediate judgment on these bottlenecks, or they just continue to debug and adjust their thinking, which is too time-consuming.

But at present, there is no way to do this. It seems that there is no better solution than continuing to study, so let's take it step by step.

Wei Qiang received the news that the director would come over tomorrow, which surprised him again. He was looking forward to it, and finally the master came over.

Although it says that titles are only honorary directors, he knows that some respected old experts and seniors don't like to hang titles, they have honorary titles, but what they do is what the director does, and the essence is the same.

And I heard that the director also has a good strategic vision and decision-making level, and it is said that he has participated in the international PK of high-end CNC machine tools and has rich experience.

Under the circumstances that the current development progress cannot be promoted quickly, this person may be able to have some high-end insights to help the team more effectively adjust and deal with the pressure brought by internal and external problems in terms of rhythm.

With him here, a large part of my pressure can be shared.

Wei Qiang plans to go back early today, get a good night's sleep, and receive the honorary director tomorrow.

"Professor Wei, we have encountered a problem and would like to ask you to take a look at it." Wei Qiang was about to leave when a researcher below called him to stop him.

Wei Qiang went to the experiment with the researcher, planning to go back after solving the problem.

This is a question about negative electrode materials. Wei Qiang discussed with the researchers for a long time, and brought several other professors and experts to study, but there was no result.

"Let's talk about it tomorrow. It happens that the new director will arrive tomorrow. You can ask his opinion tomorrow." Wei Qiang said.

Everyone thought it was okay, and it happened to let the new director show off his abilities.

On the second day, according to the agreed time, Jiang Fan sent a special vehicle to the research institute located in a park in the city center.

In the research institute, Professor Wei and his team are directing the work of the researchers below, and at the same time, they are actually looking forward to seeing the lineup of this honorary director. He must be a highly respected senior, but I don’t know who it is .

"Hey, the director is here? Okay, I understand." Professor Wei's expression changed from serious to joyful when he received the notification from the access control, and he looked at the others and said:

"The director is here, let's meet him at the door."

Everyone cheered.

A group of people hurriedly walked towards the door, and ran into Jiang Fan head-on first.

"Professor Wei." Jiang Fan was brought by Professor Zhu to meet Wei Qiang on the forum before. Although he wondered why he was here, he still wanted to say hello.

Wei Qiang was called out by Jiang Fan, looked at him and recalled it, and remembered that this was the student brought by Professor Zhu that day, and he was invited by him to come to the institute as an intern.

So he also looked at Jiang Fan with a smile and said, "Young man, your name is Jiang."

He's a little out of sorts.

"Jiang Fan." Jiang Fan took the initiative to add.

"Yes, Jiang Fan, why, I have time recently, and plan to come to my institute for an internship?" Professor Wei asked with a smile.

'practice? 'Jiang Fan almost forgot about this, and he just reflexively put it off and reminded him of it.

But when he said this, Jiang Fan faintly felt that something was wrong?But he couldn't say it all at once, so he smiled awkwardly and nodded as a response.

Wei Qiang didn't have much time to talk to Jiang Fanduo, so he patted him on the shoulder, and then he turned around and planned to continue walking outside to meet the new director.

"Professor Wei, what are you doing?" Wei Qiang and the others had just taken two steps when they were stopped by someone in front of them. Wei Qiang had seen this person before, and it was this person who handed over the mobile hard disk last time. secret.

The big secretary answered a call just now, so he was two steps behind, Jiang Fan walked in first by himself.

"Secretary Liu, you came here in person." Professor Wei hurried up to shake hands, and after shaking hands, he said to Secretary Liu:
"You came here with the director, right? Where is the director?"

"Director?" Secretary Liu was also taken aback when asked, isn't Jiang Fan standing behind them?So he pointed behind them and said, "No, that's the one."

After hearing this, a group of people turned around subconsciously and looked behind, but there was nothing special about it, except for the kid just now, there was no one else.

Professor Wei turned back to look at Secretary Liu doubtfully, "Where is there? No."

Secretary Liu also thought that this group of people was quite amusing. They didn't just stand there straight, and they didn't play guessing games with them. They walked past Wei Qiang, walked to Jiang Fan, and gestured to everyone. Jiang Fan said: "This is your new Director Jiang."

"Him?" All the experts and professors were dumbfounded for a moment.
