"Passed, my god, the C72 fullerene mask actually allows electrolyte electrons to pass."

"Who would have thought that this was passed through the mask."

"Du Wei, you have made a great contribution."

“……”

In an instant, everyone was fried.

The researchers cheered excitedly.

And the researcher who made the mask, called Du Wei, looked confused.

Du Wei didn't expect that the mask he made with fullerene could solve Xia Guo's last problem in the field of lithium batteries, lithium battery separators.

This is really impermanence!

Ye Fei and Professor Gao glanced at each other, and Ye Fei smiled: "Professor Gao, it seems that C72 fullerene still has a lot of fields that we don't know!" ”

"yes!" Professor Gao nodded, and then looked at Ye Fei with admiration: "If you don't insist on researching, can C72 fullerene be used in the field of lithium batteries." ”

"None of us know that C72 fullerene can be used in lithium batteries."

"In this way, my country does not know when it will be able to develop a lithium battery separator."

There are four core materials in the field of lithium batteries, cathode materials, anode materials, electrolytes and separators.

Xia Guo had mastered the three core materials before, and now the last diaphragm was about to be mastered.

With the current demand for lithium batteries in Xiaguo, as long as the lithium battery separator technology is mastered, the price of the manufactured lithium batteries will be reduced.

Professor Gao said: "In the past 20 years or so, lithium battery separator technology has been mastered by Beili and Dongying, and China is the largest sales market for new energy vehicles and lithium batteries. ”

"China imports a large number of lithium battery separators from abroad every year."

"This has led to a gradual increase in the price of lithium battery separators every year."

"But we had to buy it again."

"Do you know how cheap polypropylene and polyethylene, the raw materials used to make lithium battery separators, are cheap?"

"One ton is only 20,000 yuan, but after being made into a lithium battery separator, the price of one ton is 3 million yuan."

"One hundred and fifty times the difference!"

"And now we have developed a lithium battery separator." Professor Gao's eyes lit up and said: "In the future, in the field of lithium battery separators, the days when we let others slaughter them are gone." ”

All the researchers around nodded their heads, their hearts boiling.

They do scientific research, first, because they love scientific research, and secondly, they do it for the country.

Break the technological blockade and let the country master more and more technology.

With more technology, the country is rich!

When the country is rich, the people are strong!

Ye Fei looked at Du Wei and said with a smile: "Thank you, if it weren't for your mask, I wouldn't have thought of using a fullerene mask to let electrolyte ions pass through." ”

Someone laughed and said, "Du Wei, it seems that your mask is still useful?" If you make a mask in the future, Director Gao will definitely not say anything about you. ”

Du Wei scratched the back of his head and said with a dry smile: "I didn't expect this, I thought that Director Ye asked for a mask from me, and he applied it himself!" ”

Professor Gao shook his head and smiled: "I just said that Ye Fei is not that kind of person, he asked for a mask to do experiments." ”

Ye Fei said: "Okay, now that it has been proved that C72 fullerene can make lithium battery separators, we can conduct in-depth research in this field." ”

Professor Gao nodded and said, "Yes, but we are not researchers specializing in lithium batteries, we need to find professionals in the field of lithium batteries." ”

"Yes!" Ye Fei nodded.

After that, Professor Gao cooperated with Academician Guo Ruo of the Institute of Physics of the Chinese Academy of Sciences through personal relationships.

Academician Guo Ruo is a researcher and doctoral supervisor of the Institute of Physics of the Chinese Academy of Sciences, and the deputy director of the Institute of Physics of the Chinese Academy of Sciences.

He is mainly engaged in computational physics research, including computational research on magnetism and surface physics problems.

Early in the morning, Professor Gao and Ye Fei stood at the door of the Kyoto Graphene Research Institute.

The two are waiting for the arrival of Academician Guo Ruo.

Ye Fei asked, "Professor Gao, what kind of person is Academician Guo Ruo?" ”

Ye Fei felt the need to get to know Academician Guo Ruo.

After all, they are going to work together for a while in the future.

Professor Gao thought for a moment and said, "How can I say it, it's an old man with a strange temperament. ”

"Eccentric?" Ye Fei was a little apprehensive in his heart: "Then it shouldn't be easy to get along!" ”

There are quite a few such people in the scientific community, and Ye Fei finds it difficult to get along with such people.

This reminded Ye Fei of Professor Zhou Kang, who worked with Ye Fei in the computing laboratory when he was at Zhonghu University.

At that time, Ye Fei invented mathematical algorithms in the computing laboratory.

Professor Zhou Kang is a man with an eccentric temperament.

However, he admires Ye Fei's talent very much, and he is also very good to Ye Fei.

However, to others, Professor Zhou Kang is a nose not a nose, and his eyes are not eyes.

It's like the eldest in the sky, the second in the earth, and the third in him.

In the entire School of Computer Science, Professor Zhou Kang's temper is the most eccentric.

Professor Gao smiled and said, "It's okay, it's okay, when he comes, you'll know." ”

Ye Fei nodded, suppressing the doubts in his heart.

After a long time, a car pulled up to the entrance of the research institute.

Professor Gao said, "Here it is." ”

After speaking, the two greeted him.

Professor Gao personally opened the car door and said with a smile: "Academician Guo, hello! ”

Academician Guo got out of the car, and Ye Fei looked at Academician Guo.

Academician Guo is relatively tall, about 1.8 meters.

Academician Guo is in his seventies, and it is very rare for people born in the sixties of the last century to have such height.

Academician Guo was very thin, standing there like a bamboo pole, wearing glasses, and his face was full of wrinkles.

But the eyes are very bright and full of sharpness.

Academician Guo did not speak in the face of Professor Gao's greeting, but nodded lightly.

Then, Academician Guo looked at Ye Fei and said, "You are Ye Fei." ”

"Hello Academician Guo!" Ye Fei said respectfully.

"I heard Liu Shuquan's old man talk about you." Academician Guo said: "He said that you are a mathematical genius, why did you come to study materials?" ”

Academician Liu Shuquan is an academician of mathematics, and Ye Fei was in the supercomputing center of Zhonghu University back then.

Ye Fei developed a supercomputing algorithm, which was taken by Academician Liu Shuquan to check it.

Later, Liu Shuquan recommended Ye Fei Demotivation Research Institute.

Ye Fei thought for a moment and said, "It was Professor Gao who invited me here." ”

"Hmm!" Academician Guo nodded and said, "It's quite honest." ”

"Let's go, take me to see the lithium battery separator made of C72 fullerene."

Professor Gao said: "Academician Guo, please! ”

After speaking, Professor Gao led the way for Academician Guo in front.

Soon, the three of them entered the fullerene research institute to check out the mask made by Du Wei.

Academician Guo frowned instantly when he saw the mask, and said, "This thing can let electrolyte ions pass through?" ”

Professor Gao said: "Academician Guo, let me demonstrate it for you!" ”

"Good!" Academician Guo said.

Ye Fei saw Professor Gao doing it himself, Ye Fei said, "Professor Gao, I'll come!" ”

After speaking, Ye Fei started to do the operation at that time again.

Soon, a lot of data appeared on the computer screen.

"It really allows electrolyte ions to pass through." Academician Guo was stunned and said, "Who found this?" ”

Professor Gao said: "It's Ye Fei. ”

Academician Guo looked at Ye Fei in surprise and said, "Come, tell me, how did you think of using this method at that time?" ”

Ye Feidao: "The positive and negative electrodes of lithium batteries cannot conduct electricity when they are in contact with fullerene, but when electrolyte ions pass through fullerene, they generally cannot pass through. ”

"But after my research, I found that the fullerene molecule has a unique geometry and electronic structure, and the electrode material it coats exhibits excellent electrochemical reactions."

"So, it's not the fullerene that the electrolyte ions pass through, it's the fullerene molecule."

"Only fullerene molecules can allow electrolyte ions to pass through."

"At the same time, the positive and negative electrodes of lithium batteries do not touch."

Academician Guo nodded with satisfaction, and then he frowned and looked at the mask in the glass box with disgust, and said, "If you make fullerene molecules, you will make fullerene molecules, how can you make this ghost thing." ”

"Uh......" Ye Fei said with a dry smile: "This is made by a colleague of mine, I'll use it." ”

Academician Guo said: "Was this C72 fullerene discovered by the two of you?" ”

Professor Gao hurriedly shook his head and said, "No, Ye Fei found out." ”

"Huh?" Academician Guo frowned and said, "I saw that the corresponding author and the first author of the paper were the names of the two of you, didn't you discover it together?" ”

"It's not!" Professor Gao shook his head: "Ye Fei discovered it alone, and I invited him to use mathematical methods to find fullerenes with better stability than C60 fullerenes. ”

"I just wanted to try it, but I didn't expect him to find it."

"After that, according to the interval determined by Ye Fei's mathematics, he searched for fullerene, and Ye Fei also discovered C72 fullerene."

Academician Guo stared at Ye Fei and said, "How do you use mathematical methods to find C72 fullerene?" Tell me about it again. ”

"Okay!" Ye Feidao.

After speaking, Ye Fei explained to Academician Guo how to use mathematical methods to find C72 fullerene.

The more Academician Guo listened, the more his eyes lit up, and he was very surprised in his heart: "Can it still be like this?" ”

After a long time, Ye Fei stopped lecturing and said, "Academician Guo, this is how I determined the fullerene interval, and then found C72 fullerene through experiments. ”

Academician Guo nodded with satisfaction, and then said hesitantly: "Ye Fei, have you ever thought about physics?" ”

Academician Guo is interested in Ye Fei's mathematical ability.

If Ye Fei's mathematical ability is to study physics, it will be like a tiger.

"Uh......" Ye Fei looked at Academician Guo in surprise.

Academician Guo said: "Don't do mathematics, come to physics, you are very talented in the field of physics." ”

"Your talent is buried in mathematics, and you should go to physics."

"With your talent, you will definitely be able to make a big difference in the field of physics."

"If you're doing physics, you're always welcome here."

"I am the deputy director of the Institute of Physics of the Chinese Academy of Sciences, you come to me, with my identity, I will not bury your identity!"

"As long as you come, I can make you a second-level researcher next year!"

A second-level researcher is equivalent to a second-level professor.

Ye Fei scratched the back of his head and said with a dry smile: "Academician Guo, I still have a lot of other work to do, and it is not suitable to go to the Institute of Physics of the Chinese Academy of Sciences." ”

"What else do you have to do?" Academician Guo glared at Ye Fei and said, "What work can be more important than coming to the Institute of Physics of the Chinese Academy of Sciences?" ”

"Do you know how many researchers across the country want to work at the Institute of Physics of the Chinese Academy of Sciences, but they don't have the opportunity yet!"

Professor Gao saw that Academician Guo was angry, and hurriedly stepped forward to appease him, and said: "Academician Guo, you are angry, Ye Fei is indeed not suitable to work at the Institute of Physics of the Chinese Academy of Sciences, he is also the dean of the Meta Blockchain Research Institute and the Latitude Blockchain Research Institute. ”

"What if he is the dean of the Meta Blockchain Research Institute and the Latitude Blockchain Research Institute?" Academician Guo said angrily: "If he can come here to work, why can't he go to work with me?" ”

Ye Fei said with a face full of grievances: "Academician Guo, I really can't go to work at the Institute of Physics of the Chinese Academy of Sciences!" ”

"I came here to work because I knew how important it was to C72 fullerene."

"So, I stopped my work in the Meta Blockchain Research Institute and the field of mathematics and came here to work."

"When the work here is over, I will return to my original post and continue my work."

When Academician Guo heard this, he said with some loss: "Okay, since you don't come, forget it, but I will always open the door for you here, as long as you want to come, you can come at any time." ”

"Okay!" Ye Feidao.

In the following time, under the leadership of Academician Guo, Ye Fei and the others spent more than a month to make C72 fullerene into a large number of C72 fullerene molecules, and then made C72 fullerene molecules into lithium battery separators.

It's mid-November!

In the lab!

Everyone looked at the computer screen and waited for the test results of the lithium battery separator.

The lithium battery separator has been developed, and now it is time to start testing the data.

After a few moments, the lithium battery separator data was displayed on the computer.

[Thickness: 10um.]

Breathability: 20cc

Automatic shut-off mechanism: 800°C

Porosity: 30%

Thermal stability: -40°C~90°C

Mechanical strength: tensile: ~90N, transverse: ~90N

Chemical Stability: Inert

Everyone looked at this data and gasped in their hearts.

Someone exclaimed, "That's a great stat!" ”

The thinnest thickness of the best lithium battery separator in the world is 15 microns, while theirs is 10 microns.

The thinner the thickness, the better, but the better it is for mobile phones, and it is easy to carry.

If it is used in new energy vehicles, the thickness should be thickened, and the thicker the safer.

Of course, since the thinness can reach 10 microns, it can also be thickened.

Lithium battery separator is difficult to reduce thickening, and thickening is simple.

The air permeability is 20cc, and the best international lithium battery separator air permeability is 50cc.

This is 30cc less than the best battery separator in the world, which proves that Ye Fei's lithium battery separator is very good in terms of air permeability.

The automatic shut-off mechanism is that the higher the temperature, the safer, the best lithium battery separator in the world, the temperature is about 600 degrees Celsius.

And theirs is 800 degrees Celsius.

The smaller the porosity, the better, the best lithium battery separator in the world, the porosity is 35%, and their porosity is 30%.

Thermal stability, the smaller the lower limit, the larger the upper limit, the better the lithium battery separator, the temperature range of the thermal stability of the best lithium battery separator in the world is -20°C~60°C.

And their thermal stability temperature range is -40°C~80°C.

The mechanical strength must be consistent with the tensile and transverse, and the tensile and transverse strength of the best lithium battery separator in the world is 50N.

And their mechanical strength is 90N in tensile and transverse, and the greater the force, the better.

Chemical stability must be inert to be best.

Academician Guo said in surprise: "Judging from this data, the performance of the lithium battery separator we developed is the first in the world. ”

"Also, it's much better than the world's best performance in the past."

Everyone nodded and agreed with Academician Guo's statement.

They were also very pleasantly surprised, they didn't expect to develop the world's first lithium battery separator.

As one of the four core materials of lithium batteries, lithium battery separators play a great role in lithium batteries.

It is not only to isolate the positive and negative electrodes of the lithium battery, but also to ensure the service life of the lithium battery, the power of the lithium battery, the cycle and safety performance of the lithium battery.

The better the lithium battery separator, the longer the service life of the lithium battery, the higher the power, the more cycles, and the higher the safety.

At the entrance of the Graphene Research Institute!

Academician Guo looked at Ye Fei and said, "You really don't come to the Institute of Physics of the Chinese Academy of Sciences?" ”

Academician Guo still wants to fight for it, and as he gets along with Ye Fei for more than a month, he discovers Ye Fei's talent more and more.

I feel more and more that Ye Fei is buried in the field of mathematics and should come to the field of physics.

Ye Fei smiled: "If I want to study physics in the future, I will go to you." ”

"Good!" Academician Guo nodded and said, "Then we have decided so, if you want to study physics, you must come to me." ”

Ye Fei looked at the car that was coming, parked behind Academician Guo, and Ye Fei said, "The car is here." ”

After speaking, Ye Fei stepped forward and opened the back door, and after Academician Guo walked up, he pulled down the window and waved at Ye Fei: "Goodbye!" ”

"Goodbye!"

After the car left, Ye Fei returned to the Fullerene Institute.

Professor Gao's office!

Professor Gao sat on the office chair, looked at Ye Fei who walked in, and said, "Is Academician Guo gone?" ”

"Gone!" Ye Feidao.

Professor Gao said: "Now let's discuss, what to do with the lithium battery separator next?" ”

"Hmm!" Ye Fei sat on the chair opposite Professor Gao and said, "My suggestion is to lease the patent to the outside world, such as leasing it to some companies in our country that make lithium battery separators. ”

"That's one way to do it." Professor Gao said: "However, there is also a statement about which companies to lease to, and the Kyoto Graphene Research Institute is a state-owned enterprise. ”

"Generally, our research is leased to state-owned enterprises."

Ye Fei said: "Professor Gao, see if you can rent it to a private enterprise." ”

Ye Fei wants to lease the patent of lithium battery separator to Enjie shares.

After all, in order to adhere to the lithium battery separator, the company has adhered to it for many years and spent countless manpower, material and financial resources.

With their spirit, Ye Fei also wanted to help them.

"Private enterprise?" Professor Gao was surprised and said, "What kind of private enterprise can make you speak." ”

"Engjie shares!" Ye Feidao: "Xu Li, chairman of the company, I once talked to him, this company has also been developing lithium battery separators, but it has not reached the international average. ”

"At the same time, this company's lithium battery separator is also the best lithium battery separator technology among all companies in Xia Guo."

"But our country's lithium battery separator technology has always lagged behind the international level, and this company's lithium battery separator has always been in a loss-making state."

"But they're still working on lithium battery separators."

"With their perseverance, I would like to lease the lithium battery separator technology to this company."

Professor Gao thought for a while and said, "It's not impossible, it's just that we have to report this matter to the top, and only if the above agrees, we can talk to this company." ”

"Of course, before that, you also have to contact the people of this company."

"Only if they agree to the matter, we can apply upwards."

"If the application is made at that time, the above will agree that we will lease the patent to a private enterprise."

"But this private enterprise is not renting, isn't it a joke!"

Ye Fei said with a smile: "With our lithium battery separator technology, they will definitely rent it." ”

"I know." Professor Gao said, "Isn't this just in case! ”

"That's what you said." Ye Fei said: "I will talk to the people of Enjie." ”

"Hmm!" Professor Gao nodded.

After that, Ye Fei left Professor Gao's office and made a WeChat call to Xu Li, chairman of Enjie Co., Ltd.

The meeting room of the company!

Xu Li sat in the first seat, and below sat the shareholders.

"Dong Xu, our profit this month is 41.7 million." A director said: "Without the research and development of lithium battery separators, our profit would be at least 60 million. ”

"Xu Dong, we really can't develop lithium battery separators anymore, and we will lose tens of millions of dollars every year because of lithium battery separators."

"It's okay if it comes out, but it's been many years, and it hasn't come to fruition."

"My suggestion is to cut the lithium battery separator business."

"In this way, we can earn tens of millions more."

Xu Li looked at the rest of the shareholders and asked, "Do you think so too?" ”

The rest of the shareholders nodded.

One of the shareholders said: "Xu Dong, many companies across the country have developed lithium battery separators, but none of them have reached the international average, and they have all cut this business one by one." ”

"Therefore, we can no longer hold on, and we should also cut the lithium battery separator business."

Xu Li saw that all shareholders supported the cutting of the lithium battery separator business, and he was very sad in his heart.

It has always been Xu Li's dream to make Xia Guo's lithium battery separator comparable to the international level.

Unless it is a last resort, Xu Li does not want to cut the lithium battery separator business.

He was afraid that as long as he cut it himself, Xia Guo would never have lithium battery separator technology again.

After all, the company is the best company in lithium battery separator technology among all the enterprises in Xia Guo.

Enjie shares can not make the lithium battery separator comparable to the international level, let alone other companies!

"Okay......" Xu Li was about to say that he would cut off the lithium battery separator business.

At this time, the mobile phone in his pocket vibrates.

Xu Li took out his mobile phone and took a look, and found that it was Ye Fei who invited him to make a voice call.

Xu Li hurriedly said, "Everyone, I'm sorry, I'll answer a call." ”

After speaking, Xu Li walked out quickly, walked to the window of the corridor, and connected to Ye Fei's WeChat.

Xu Li smiled and said, "Dean Ye, hello! ”

"Hello, Mr. Xu!" Ye Fei said with a smile: "Mr. Xu, let's make a long story short, I have a lithium battery separator technology here, its efficacy has reached the first in the world, and the thickness is ......."

Ye Fei said the data of the lithium battery separator developed.

After Xu Li listened, his eyes widened in surprise, and he said, "Dean Ye, you are not joking, how can there be a lithium battery separator with such good performance in this world." ”

Ye Fei said: "Do you think I will joke with you about this?" ”

Xu Li thought about it for a while, indeed, Ye Fei would not joke about this.

Xu Li asked, "Dean Ye, where did this technology come from?" Which institute developed it? ”

Ye Feidao: "It was developed by the Fullerene Research Institute under the Kyoto Graphene Research Institute. ”

"It turned out to be Xia Guo's research institute?" Xu Li exclaimed.

He also thought that he could develop such a good lithium battery separator, which was a foreign research institute.

After all, Xia Guo's lithium battery separator technology has always lagged behind the international average.

Such a good lithium battery separator must have been developed by a foreign research institute.

Ye Feidao: "I don't talk nonsense with you, I am ready to lease this lithium battery separator patent to you, do you agree?" ”

"If I agree, I still need to apply to the above."

"Rent it to us?" Xu Li said in astonishment.

"Yes!" Ye Fei said: "Do you agree?" If I agree, I'll apply to the above now. ”

Xu Li said suspiciously: "Dean Ye, why are you helping me?" ”

Ye Fei said: "Because of what you said to me at the airport, I admire your persistence in the lithium battery separator, is this reason enough?" ”

"Of course!"

"Does that mean that you agree to lease the patent of lithium battery separator?"

"Yes!" Xu Li said with joy.

He felt that this was really pie in the sky, he just happened to meet Ye Fei at the airport, and after talking to Ye Fei, such a good thing happened to him.

With the performance of this lithium battery separator, as long as it is made, it will definitely be sought after all over the world.

Ye Fei said: "Okay, I will apply to the above next, you wait for my news." ”

After speaking, the two hung up the phone, and Ye Fei told Professor Gao the news, saying that Enjie had agreed.

After that, Professor Gao applied upwards.
