Chapter 184 The world’s first lithium battery separator

"Passed, my God, the C72 fullerene mask can actually allow electrolyte electrons to pass through."

"Who would have thought that it would pass through the mask."

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

"..."

In an instant, everyone was in a panic.

The researchers cheered excitedly.

The researcher who made the facial mask, named Du Wei, looked confused.

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

This is really an unpredictable life!

Ye Fei and Professor Gao looked at each other, and Ye Fei smiled and said: "Professor Gao, it seems that C72 fullerene has many other areas that we don't know about!"

"Yes!" Professor Gao nodded, and then looked at Ye Feidao with admiration: "If you hadn't insisted on researching, could C72 fullerene be used in the field of lithium batteries?"

"We didn't know that C72 fullerene could be used in lithium batteries."

"In this way, our country still doesn't know when it will develop a lithium battery separator."

The four core materials in the lithium battery field are cathode materials, anode materials, electrolytes and separators.

Xia Guo had mastered the three core materials before, and now he has to master the last barrier.

With the current demand for lithium batteries in Xia State, as long as the lithium battery separator technology is mastered, the price of manufactured lithium batteries will drop.

Professor Gao said: "In the past twenty years or so, lithium battery separator technology has been mastered by North Korea and Japan, and my country is the largest sales market for new energy vehicles and lithium batteries."

"Our country imports a large amount of lithium battery separators from abroad every year."

"This has caused the price of lithium battery separators to rise step by step every year."

"But we had to buy it."

“Do you know how cheap polypropylene and polyethylene, the raw materials for making lithium battery separators, are?”

“One ton is only 20,000 yuan, but after being made into lithium battery separators, the price per ton is 3 million yuan.”

"The price difference is one hundred and fifty times!"

"And we have now developed a lithium battery separator." Professor Gao said with bright eyes: "In the field of lithium battery separators, the days when we were left to others to dominate are gone forever."

All the researchers surrounding him nodded, their hearts boiling with excitement.

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

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

The more technology, the richer the country will be!

When the country is rich, the people will be strong!

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

Someone laughed and said, "Du Wei, does it look like your facial mask is still useful? If you make facial masks in the future, Director Gao will definitely not criticize you."

Du Wei scratched the back of his head and laughed dryly: "I didn't expect this to happen. I thought Director Ye asked for a facial mask from me and applied it himself!"

Professor Gao shook his head and said with a smile: "I just said that Ye Fei is not that kind of person. He wants the mask just for experiments."

Ye Feidao: "Well, now that it has been proven that C72 fullerene can be used to 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.

Afterwards, Professor Gao relied on personal connections to cooperate with Academician Guo Ruo of the Institute of Physics, Chinese Academy of Sciences.

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

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 it was necessary to get to know Academician Guo Ruo.

After all, they will be working together for a while in the future.

Professor Gao thought for a moment and then said: "How should I put it? He is an old man with a weird temperament."

"Weird temperament?" Ye Fei said with some anxiety: "That must be difficult to get along with!"

There are quite a few people like this 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 an eccentric person.

However, he admired Ye Fei's talent very much and treated Ye Fei very well.

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

It's like the sky is the boss, the earth is the second boss, and he is the third boss.

In the entire School of Computer Science, Professor Zhou Kang has the weirdest temper.

Professor Gao chuckled and said, "It's okay, it's okay. You'll know when he comes."

Ye Fei nodded and suppressed the doubts in his heart.

After a long time, a car stopped at the entrance of the institute.

Professor Gao said: "Here we come."

After saying that, the two of them stepped forward to greet him.

Professor Gao opened the car door himself and said with a smile: "Hello, Academician Guo!"

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

Academician Guo is relatively tall, about 1.8 meters tall.

Academician Guo is over 70 years old. Very few people born in the 1960s have such a height.

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

But his eyes are very bright and full of sharpness.

Academician Guo didn't say anything when facing Professor Gao's greetings, he just nodded lightly.

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

"Hello, Academician Guo!" Ye Fei said respectfully.

"I heard that old man Liu Shuquan said something about you." Academician Guo said, "He said you were a mathematical genius. Why did you come to study the materials?"

Academician Liu Shuquan is an academician in mathematics. When Ye Fei was working at the Supercomputing Center of Zhonghu University, he was a mathematician.

Ye Fei developed a supercomputing algorithm, and Academician Liu Shuquan took people to check it out.

Later, Liu Shuquan recommended Ye Fei to go to the Power Research Institute.

Ye Fei thought for a moment and then said, "Professor Gao invited me here."

"Yeah!" 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.

Soon, the three of them entered the Fullerene Research Institute to check out the facial mask produced by Du Wei.

When Academician Guo saw the mask, he frowned and said, "This thing can allow electrolyte ions to pass through?"

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

"Okay!" Academician Guo said.

Ye Fei saw Professor Gao doing it himself, Ye Fei said: "Professor Gao, let me do it!"

After saying that, Ye Fei went through the operation again.

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

"It can really allow electrolyte ions to pass through." Academician Guo said in shock: "Who discovered this?"

Professor Gao said: "It's Ye Fei."

Academician Guo looked at Ye Fei in surprise and said, "Come on, tell me, how did you come up with the idea of ​​using this method?"

Ye Fidao: "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."

"But through research, I found that fullerene molecules have unique geometric and electronic structures, and the electrode materials coated by them show excellent electrochemical reactions."

"So, it's not the fullerene that the electrolyte ions are passing through, but the fullerene molecules."

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

"At the same time, it also prevents the positive and negative electrodes of the lithium battery from contacting."

Academician Guo nodded with satisfaction, then he frowned and looked at the mask in the glass box with disgust, and said: "You make fullerene molecules when you make them. How did you make this damn thing?"

"Uh..." Ye Feiqian smiled and said: "This is made by a colleague of mine. I will use it."

Academician Guo asked: "Did you two discover this C72 fullerene?"

Professor Gao quickly shook his head and said, "No, it was Ye Fei who discovered it."

"Huh?" Academician Guo frowned and said, "I saw that the corresponding author and first author of the paper were your names. Didn't you two jointly discover it?"

"No!" Professor Gao shook his head: "Ye Fei discovered it alone. At that time, I invited him to use mathematical methods to find fullerenes that are more stable than C60 fullerene."

"I just wanted to give it a try, but I didn't expect that he would actually find me."

"Then we searched for fullerenes according to the interval determined by Ye Fei's mathematics, and it was Ye Fei who discovered C72 fullerene."

Academician Guo stared at Ye Fei and said: "We found C72 fullerene using mathematical methods. How to use it? Tell me again."

"Okay!" Ye Feidao.

After finishing 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 shone, and he was very surprised: "Can it still be like this?"

After a long time, Ye Fei stopped the lecture 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 pursuing physics?"

Academician Guo took a fancy to Ye Fei's mathematical ability.

If Ye Fei's mathematical ability were used to study physics, it would be even more powerful.

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

Academician Guo said: "Stop doing mathematics and come to physics. You are very talented in the field of physics."

"Your talent is buried in mathematics and should be in the field of physics."

"With your talent, you will definitely be able to make great achievements in the field of physics."

"If you are interested in physics, you are always welcome here."

"I am the deputy director of the Institute of Physics, Chinese Academy of Sciences. If you come to my place, with my identity, I won't hide 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 for me to go to the Institute of Physics, Chinese Academy of Sciences."

"What other job do you have?" Academician Guo stared at Ye Feidao: "What job is more important than coming to the Institute of Physics, Chinese Academy of Sciences?"

"Do you know how many scientific researchers across the country want to work in the Institute of Physics, Chinese Academy of Sciences, but they haven't had the chance yet!"

Professor Gao saw that Academician Guo was angry and quickly stepped forward to comfort him and said: "Academician Guo, please calm down. Ye Fei is indeed not suitable to work at the Institute of Physics, Chinese Academy of Sciences. He is also a member of the Yuan Blockchain Research Institute and Latitude Blockchain Dean of the Institute.”

"So what if he is the dean of Yuan Blockchain Research Institute and Latitude Blockchain Research Institute?" Academician Guo said angrily: "He can work here, why can't he work with me?"

Ye Fei said with aggrieved face: "Academician Guo, I really can't work at the Institute of Physics, Chinese Academy of Sciences!"

"I came here to work because I know C72 fullerene is very important."

“So, I stopped working at the Meta Blockchain Research Institute and in the field of mathematics and came to work here.”

"After I finish working here, I will return to my original position and continue my work."

When Academician Guo heard this, he said with some disappointment: "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.

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

It’s mid-November!

In the laboratory!

Everyone is looking at the computer screen, waiting for the test results of the lithium battery separator.

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

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

[Thickness: 10um

Breathability: 20cc

Automatic shutdown mechanism: 800°C

Porosity: 30%

Thermal stability: -40°C~90°C

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

Chemical stability: inert]

Everyone looked at this data and took a deep breath.

Someone exclaimed: "This data is too good!"

The world's best lithium battery separators have the thinnest thickness of 15 microns, while theirs is 10 microns.

Thinner does not mean better, but it is better when used on mobile phones and is easier to carry.

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

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

It is difficult to reduce the thickness of lithium battery separators, but easy to thicken them.

The air permeability is 20cc, and the best lithium battery separator in the world has an air permeability of 50cc.

This is 30cc less than the best battery separators in the world, which proves that Ye Fei’s lithium battery separators are very excellent in terms of breathability.

The automatic shutdown mechanism is that the higher the temperature, the safer it is. The temperature of the best lithium battery separator in the world is around 600 degrees Celsius.

And theirs is 800 degrees Celsius.

The smaller the porosity, the better. The best lithium battery separators in the world have a porosity of 35%, while their porosity is 30%.

For thermal stability, the smaller the lower limit and the larger the upper limit, the better the lithium battery separator is. The thermal stability of the best lithium battery separators in the world ranges from -20°C to 60°C.

Their thermal stability ranges from -40°C to 80°C.

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

Their mechanical strength is 90N in tensile and transverse directions, the stronger the better.

Chemical stability must be inert for best.

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

“And it’s much better than the world’s top performer in the past.”

Everyone nodded and agreed with Academician Guo's statement.

They were also very surprised. They did not 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 huge role in lithium batteries.

It not only isolates the positive and negative electrodes of lithium batteries, but also ensures the service life of lithium batteries, the power of lithium batteries, the cycle and safety performance of lithium batteries.

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 door of the Graphene Research Institute!

Academician Guo looked at Ye Feidao: "You really don't want to come to the Institute of Physics, Chinese Academy of Sciences?"

Academician Guo still wanted to fight for it. After spending more than a month with Ye Fei, he discovered Ye Fei's talent more and more.

More and more, I felt that Ye Fei was buried in the field of mathematics and should come to the field of physics.

Ye Fei smiled and said, "If I want to study physics in the future, I will come to you."

"Okay!" Academician Guo nodded and said, "Then we have settled. If you want to study physics, you must come to me."

Ye Fei looked at the approaching car and stopped behind Academician Guo. Ye Fei said, "The car is here."

After saying that, Ye Fei stepped forward and opened the rear door. After Academician Guo walked up, he pulled down the window and waved to Ye Fei: "Goodbye!"

"goodbye!"

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

Professor Gao's office!

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

"Let's go!" Ye Feidao said.

Professor Gao said: "Now let's discuss how to deal with the lithium battery separator next?"

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

"This is a way." Professor Gao said: "However, there must be an explanation for which companies are rented to. The Kyoto Graphene Research Institute is a state-owned enterprise."

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

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

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

After all, Enjie has been adhering to the lithium battery separator 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 said in surprise: "What kind of private enterprise can make you speak?"

"Enjie Co., Ltd.!" Ye Feidao said: "I once talked with Xu Li, the chairman of Enjie Co., Ltd., and this company has also been developing lithium battery separators, but it has never reached the international average level."

"At the same time, this company's lithium battery separator also has 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 at a loss."

"But they are still working on lithium battery separators."

"With their persistence, I want to lease lithium battery separator technology to this company."

Professor Gao thought for a while and then said: "It's not impossible, but we have to report this matter to the superiors. Only with the approval from the superiors can we talk to this company."

"Of course, before that, you also need to contact the people in this company."

“Only if they agree to this can we apply upwards.”

"If the application is approved by then, the higher authorities will agree to lease our patents to private enterprises."

"But this private enterprise doesn't want to rent anymore. Isn't this a joke?"

Ye Fei smiled and said: "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 Feidao said, "I will talk to the people at Enjie Shares."

"Yeah!" Professor Gao nodded.

Afterwards, Ye Fei left Professor Gao's office and called Xu Li, chairman of Enjie Co., Ltd. on WeChat.

Enjie Share Conference Room!

Xu Li sat in the first seat, with all the shareholders sitting below him.

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

"Director Xu, we really can no longer develop lithium battery separators. We lose tens of millions every year because of lithium battery separators."

"It would be fine if there were results, but it has been so many years and there has been no results."

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

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

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

The other shareholders nodded.

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

"So, we can no longer persist and should cut off the lithium battery separator business."

Xu Li felt very sad when he saw that all shareholders supported the axing of the lithium battery separator business.

It has always been Xu Li's dream to make Xia Guo's lithium battery separators comparable to international standards.

Unless absolutely necessary, Xu Li does not want to cut off the lithium battery separator business.

He was afraid that if he cut it off, Xia Guo would no longer have lithium battery separator technology.

After all, Enjie Co., Ltd. is the company with the best lithium battery separator technology among all companies in Xia State.

Even Enjie Co., Ltd. cannot make lithium battery separators comparable to international standards, let alone other companies!

"Okay..." Xu Lizheng was about to cut off the lithium battery separator business.

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

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

Xu Li quickly said: "Everyone, I'm sorry, I'm taking a call."

After saying that, Xu Li quickly walked out, walked to the window in the corridor, and connected to Ye Fei's WeChat.

Xu Li smiled and said, "Hello, Dean Ye!"

"Hello, Mr. Xu!" Ye Fei smiled and said: "Mr. Xu, let's make a long story short. I have a lithium battery separator technology here. Its efficiency ranks first in the world, and its thickness is..."

Ye Fei talked about the data of the lithium battery separator developed.

After Xu Li heard this, his eyes widened in surprise and said, "Dean Ye, are you kidding me? How could there be a lithium battery separator with such good performance in this world?"

Ye Feidao: "Do you think I would joke with you about this?"

Xu Li thought for a moment and realized that indeed, Ye Fei would not joke about this matter.

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

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

"It's actually Xia Guo's research institute?" Xu Li exclaimed.

He thought it was a foreign research institute that could develop such a good lithium battery separator.

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 won't talk nonsense to you. I'm going to rent this lithium battery separator patent to you. Do you agree?"

"If it's agreed, I still need to apply to the higher authorities."

"Lease it to us?" Xu Li asked in shock.

"Yes!" Ye Feidao: "Do you agree? If you agree, I will apply to the superiors now."

Xu Li asked doubtfully: "Dean Ye, why are you helping me?"

Ye Feidao: "Because of what you said to me at the airport, I admire your insistence on the lithium battery separator. Is this reason enough?"

"certainly!"

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

"Yes!" Xu Li said happily.

He felt that this was really pie in the sky. He just happened to meet Ye Fei at the airport and had a conversation with Ye Fei, but such a good thing happened to him.

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

Ye Feidao: "Okay, I will apply to the higher-ups next. You wait for my news."

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

After that, Professor Gao applied.
