From a university student to a chief academician

Chapter 183 Stuck Neck Technology One - Lithium Battery Separator
The president of Jinling University did what he said, and after the dean left, he called Ye Fei.

The principal sat on the office chair, held the phone and said with a smile: "Hi, hello, is this Dean Ye? I'm Yuan Xiang, the president of Jinling University!"

Ye Fei was stunned for a moment, and then said: "Principal Yuan, hello!"

At this moment, Ye Fei was sitting in the VIP waiting room at the airport.

Ye Fei went to the Kyoto Graphene Research Institute after finishing the work of the Yuan Blockchain Research Institute.

Ye Fei does not have to do everything himself in the research of Yuan Blockchain Research Institute, the core research has already been developed.

As the dean of the Metablockchain Research Institute, in the research of the Metablockchain system, he only needs to point out the research direction and how to do it.

Unless the people under his command can't research successfully, or need to speed up the research, Ye Fei will do it himself.

But in the current situation, the metablockchain system does not have any competitors in the world, so there is no need to rush to study.

Ye Fei put more energy into mathematical research and fullerenes.

After the discovery of C72 fullerene, Ye Fei also wanted to know what applications C72 fullerene could have.

Yuan Xiang smiled and said, "Dean Ye, you see that a great genius like you has come to Jinling, so you should come to Jinling University for a sit-down!"

Ye Fei smiled and said, "Principal Yuan, you're flattering me. I'm not a great genius. As a native of Jinling, Jinling University has always been my admiration. I'll go there if I have the chance."

"When will there be a chance?" Yuan Xiang was overjoyed, and asked urgently, "Is it possible soon?"

"Uh..." Ye Fei hesitated and said, "I may not have a chance recently, I will be very busy recently!"

Feeling a little lost, Yuan Fei asked, "What are you busy with? Maybe our school can provide some meager help."

Ye Fei laughed and said, "I'm not busy, I'm just busy!"

Yuan Fei shook his head and smiled softly: "If you are busy all the time, then others will be even more busy."

Judging from Ye Fei's achievements, each of Ye Fei's research is very meaningful and has made great contributions to the country and society.

If Ye Fei's research is all busy, what are the rest of the researchers doing every day?
Ye Feidao: "Recently, I mainly do two jobs, research in the fields of mathematics and materials."

"Oh, yes!" Yuan Fei patted his head with a look of sudden realization: "You discovered C72 fullerene, and you should be developing the application of C72 fullerene."

"Yes!" Ye Fei nodded.

Yuan Fei asked: "This is a big deal, since that's the case, I won't bother you."

"Ok."

After hanging up the phone, Yuan Fei smiled wryly in his heart, and failed again.

Yuan Fei has always wanted to have a face-to-face conversation with Ye Fei, but he never had the chance.

Either Ye Feiren was not in Jinling, or Ye Fei was too busy to talk.

It was the same this time, Ye Fei was too busy, the two of them didn't have a chance to talk.

Yuan Fei cheered himself up secretly, saying: "It's okay, good things take time, it's normal for a talent like Ye Fei to visit thatched cottage every day."

"If it doesn't work this time, there will be a next time. If it doesn't work next time, there will be a next time."

Airport, VIP waiting room!
Ye Fei put the mobile phone in his trouser pocket, then took the tea in front of him and drank it slowly.

"Hello, this is Dean Ye!"

At this moment, a middle-aged man walked up to Ye Fei.

The middle-aged man is about 1.7 meters tall, wearing a black suit, with a round face and a friendly smile.

Behind the middle-aged man followed a 30-year-old young man in a black suit.

The young man has a fair face, wears glasses, and is tall and thin, looking very gentle.

The young man was carrying a black leather bag, looking like a subordinate of a middle-aged man.

"You are?" Ye Fei looked at the middle-aged man suspiciously, then stood up.

The middle-aged man stretched out his hand and said with a smile, "I am Xu Li, chairman of Enjie Co., Ltd."

Ye Fei shook hands with him and said with a smile, "Hi, Mr. Xu!"

Many people may not have heard of Enjie shares.

Enjie's main business is to provide a variety of packaging and printing products, packaging products and services, as well as lithium battery separator films, aluminum-plastic films and water treatment films.

The company's wet-process lithium battery separator business is connected with the new energy vehicle industry.

Xiaguo is the largest sales market for new energy vehicles, and Enjie should develop very well.

However, the lithium battery separator has not developed well in any company in Xiaguo, and there is a big gap compared with the international ones.

The same is true for Enjie shares. Among the many businesses of Enjie shares, the development of lithium battery separators is the worst, even reaching the point of loss.

However, tall despite being short, Enjie's lithium battery separator is the best developed among all companies in Xiaguo.

Lithium battery diaphragms of almost all lithium battery companies in Xiaguo are imported from abroad.

Xu Li smiled and said, "Can I sit down?"

"Of course!" Ye Fei smiled and said, "Please!"

Hearing this, Xu Li pulled out a chair and sat opposite Ye Fei, then asked the waiter for a cup of tea.

Xu Li's assistant also sat down on a chair not far away.

Xu Li smiled and said, "I've heard about Dean Ye's name for a long time. I used to see it on the news and on the Internet, but today I finally saw him in person."

Ye Fei shook his head and said with a smile, "Mr. Xu deserves the award."

"Mr. Xu, I have read the report of Enjie shares before, but I have a big doubt."

"You want to ask, why doesn't my company cut off the lithium battery separator business, right?"

Ye Fei nodded and said, "Yes."

"Actually, not only you ask me that question, many people will ask me that question." After taking a sip of the tea in front of him, Xu Li looked at the stream of people coming and going outside the glass.

"In the field of lithium batteries, there are four main materials, namely positive electrode material, negative electrode material, electrolyte and separator."

"Our country has conquered the first three and can manufacture them to reach the international average level."

"Only the diaphragm, my country's lithium electronic diaphragm technology lags behind the international level."

"Our company is the company with the best lithium battery diaphragm technology in Xiaguo."

"If our company abandons the lithium battery separator, when will Xiaguo produce a lithium battery separator comparable to the international level?"

"Even if our company is losing money, we must insist on developing lithium battery separators, and we cannot cut off the lithium battery separator business."

Ye Fei nodded secretly in his heart, admiring Xu Li's demeanor.

There are very few companies that would rather lose money and persist in this business, just to let their own country have this technology.

From a profit standpoint, this is stupid.

But just because no one understands them, what they insist on is not interests, but hope.

I hope that one day, the country can develop this technology that is comparable to the international level.

Ye Fei smiled and said, "Mr. Xu, one day, our Xiaguo will be able to produce a lithium battery separator that is comparable to the international level."

Xu Li smiled wryly: "I hope!"

Xu Li has persisted in this idea for many years, many times brought him hope, many times brought him disappointment.

The more hope, the more disappointment!

But Xu Li was still unwilling to give up.

He didn't know what the future awaited.

But what he insists on now is just one breath.

If this breath is relieved, he will feel very lost in his heart.

Every time he wanted to give up, he would say to himself: "It's been so many years, maybe it's not far from success."

Every time after finishing this sentence, he continued to insist on it.

Xu Li is like a guardian of the island, guarding the most advanced territory in the field of lithium battery separators in Xiaguo.

It is equivalent to a technology gatekeeper!
[Passengers flying from Jinling to Kyoto are invited to board the plane! 】

At this time, the boarding voice was played on the radio.

Ye Fei stood up and said, "Mr. Xu, please leave a contact information, we will talk again when we have a chance."

There was a hint of surprise on Xu Li's face, he didn't expect Ye Fei to propose to leave a contact information for each other.

Xu Li smiled and said, "Okay."

After speaking, the two added WeChat to each other.

"Goodbye!" Ye Fei said.

"goodbye!"

Three hours later, Ye Fei arrived at the Kyoto Graphene Research Institute.

After entering the Fullerene Research Institute, Professor Gao Dingyi greeted him with a smile: "You are finally here. If you don't come, I would like to go to Jinling and kidnap you."

Ye Fei couldn't laugh or cry: "How long have I been gone, I'm going to Jinling to tie me up."

"Our research is very important. If you are not here, we have lost a main force."

Professor Gao dragged Ye Fei quickly to the center of the research institute, and said, "Let me show you what we have made with C72 fullerene during this period of time."

Soon, Professor Gao pulled Ye Fei into a research room.

Many researchers are doing research in the laboratory.

Professor Gao walked to a table, pointed to something like white cream on it, and said, "Look!"

"This is a water-soluble fullerene that can treat some skin diseases."

"It's about twice as strong as the water-soluble fullerenes of C60."

Ye Fei asked in surprise, "So tall?"

"Yes!" Professor Gao nodded: "It's so high. It was just developed and the data was tested. I was also surprised after reading it. The material is exactly the same as C60 water-soluble fullerene."

"Just change the fullerene from C60 to C72, but the water-soluble fullerene produced is twice that of C60."

"From this point of view, the effect of C72 is much stronger than that of C60."

"Yeah!" Ye Fei nodded and said, "That's true."

"Look at this again." Professor Gao pointed to something next to him.

It was a square translucent sheet the size of a human head.

"According to the characteristics of C72, we developed C72 non-fullerene, which is the acceptor photovoltaic material of C72 non-fullerene."

Fullerenes and non-fullerenes are two relative things.

If a certain sequence of fullerenes is discovered, non-fullerenes of this sequence can be quickly developed.

Ye Fei picked up the acceptor photovoltaic material with his left hand, and it felt very thin and light. It was much lighter and thinner than the C60 non-fullerene acceptor photovoltaic material that Ye Fei had come into contact with before.

Ye Fei grabbed the other side of the acceptor photovoltaic material with his right hand and bent it hard. After the photovoltaic material was bent to [-] degrees, there was no crack.

After the hand is released, it quickly springs back and returns to its original shape.

Receptor photovoltaic materials can absorb solar energy and convert it into electricity.

Moreover, the material itself has low manufacturing cost, light weight, translucence, and strong flexibility.

Ye Fei said in surprise: "This material is too light and flexible!"

Professor Gao nodded with a smile, "Yes, do you know its weight and flexibility?"

Ye Fei looked at Professor Gao, waiting for his answer.

Professor Gao said: "The mass of the piece in your hand is only one catty, and the maximum flexibility is 135 degrees."

Ye Fei said in astonishment: "It's so light and soft."

The receptor photovoltaic material in Ye Fei's hands is [-] square centimeters, which is a square with a side length of [-] centimeters.

If it is a C60 non-fullerene acceptor photovoltaic material, the mass of such a acceptor photovoltaic material is about four kilograms, and the flexibility is [-] degrees.

"Yes!" Professor Gao nodded.

Ye Fei said: "How much heat can it absorb?"

Professor Gao said: "This kind of acceptor photovoltaic material is one meter long and wide. When the sun is at its strongest, it can absorb [-] watts in an hour and [-] watts in a day."

"How much?" Ye Fei's eyes widened in surprise.

You should know that even C60 receptor photovoltaic materials can absorb up to [-] watts of electricity per hour when the sun is at its strongest.

Professor Gao added: "It can absorb [-] watts in an hour, and can absorb [-] watts in a day."

Ye Fei suppressed the surprise in his heart, and said: "If you say this, the solar photovoltaic panels made of C72 non-fullerene only need [-] cubic meters of solar energy absorbed, which can meet the daily use of a family."

One kilowatt is one kilowatt-hour of electricity, and the average family uses ten kilowatt-hours of electricity a day.

Professor Gao nodded and said, "Yes!"

Ye Fei clicked his tongue and exclaimed: "This is too powerful, Professor Gao, this thing can be popularized and used by every household. After all, only one solar photovoltaic panel of [-] cubic meters can meet the needs of a family for a day. energy used."

Professor Gao said: "Of course it can be popularized, but this thing is suitable for use in rural areas, and not every household in cities can use it."

"After all, there are many buildings in cities, but few flats and villas."

"This thing can't be placed in a building, it can only be placed on the top floor of a building, a flat roof or a villa roof."

"Yeah!" Ye Fei nodded and smiled: "Indeed, I took it for granted, this thing is not suitable for cities, only for rural areas."

Professor Gao said: "Although cities cannot use it, it can still be used in rural areas, and it can also be used in the field of national power generation."

"I believe it can help the country generate a lot of electricity, and the discovery of sunlight is a renewable, clean, and pollution-free energy source."

"The country has always advocated this method of power generation."

"Yes!" Ye Fei nodded: "But Professor Gao, the biggest characteristic of fullerene is anti-oxidation, we should start from this aspect."

"What you said is right!" Professor Gao said: "This is also the focus of our next research. We need to consider what aspects of anti-oxidation to start with."

"If you start with skin care products and antiseptic materials, it would be overkill."

"My idea is to start with nanomaterials and electron transport materials."

Ye Feidao: "Have you thought about the lithium battery diaphragm material?"

Ye Fei thought of Xu Li whom he met at the airport. Xu Li had been developing lithium battery separators.

After talking with Xu Li, Ye Fei also wanted to develop a lithium battery separator, so that Xia Guo could manufacture all four core materials in the lithium battery field.

The so-called lithium battery separator, to put it simply, is to isolate the positive and negative electrodes of the battery to prevent short circuit caused by contact between the two electrodes.

In addition, it also has the function of allowing electrolyte ions to pass through.

"Lithium battery separator?" Professor Gao froze for a moment.

Then he shook his head and smiled wryly: "Ye Fei, I should have taught you that fullerene cannot work in the field of lithium batteries."

"It isolates oxygen, but it doesn't have the properties of conductivity and isolation of electrons."

"Why don't you try to study it." Ye Fei said: "After all, what you said is the knowledge of C60 fullerene."

"Maybe C72 fullerene has some properties that we haven't discovered."

Ye Fei felt that since fullerenes can isolate oxygen, they might also be able to isolate other things.

It's just that we haven't found out yet.

Professor Gao thought for a while, and felt that what Ye Fei said made sense.

C72 fullerene is a newly discovered material, and there are still many fields that can be developed.

Professor Gao nodded and said: "Okay, let's study it, but I can't guarantee whether there will be new discoveries."

Ye Fei smiled and said, "Try it, maybe you can make new discoveries."

Next, Ye Fei and others started to work.

in the laboratory!

Ye Fei was sitting on a stool, and there was a C72 fullerene sheet on the table in front of him.

This is not a C72 fullerene acceptor photovoltaic material, but Ye Fei made C72 fullerene into a thin plate.

Ye Fei took an electric pen to touch the acceptor photovoltaic material.

At the same time, Ye Fei looked at the electric meter beside him to see if the pointer on it moved.

If the pointer moves, it means it can conduct electricity.

If the pointer does not move, it means it cannot conduct electricity.

Soon, Ye Fei shook his head and said, "Sure enough, it can't conduct electricity."

"However, being non-conductive does not necessarily mean that lithium battery separators cannot be manufactured!"

"After all, the first characteristic of a lithium battery separator is to isolate the positive and negative electrodes."

"Next, let's see if we can transport electrolyte ions."

After speaking, Ye Fei put the fullerene sheet into a cylindrical transparent glass box.

The transparent glass box is connected to the computer.

Then turn on the switch, and the transparent glass box is filled with electrolyte ions.

Many data are displayed on the computer screen.

After a long time, Ye Fei shook his head regretfully: "Sure enough, it still doesn't work. It seems that fullerenes really can't be used in the field of lithium batteries."

"Look, I made a mask with C72 fullerene." A young man walked in from the outside, holding a black mask in his hand.

Professor Gao looked at the young man and said helplessly, "You kid, you used fullerene to whiten the skin again. Are we studying fullerene just to make people more beautiful?"

The young man said with a smile: "I use leftovers, and you don't need those leftovers, so you should throw them away. Why don't I use them to make something I like."

Professor Gao waved his hands irritably: "Do it, do it, as long as you don't take out the research institute, you can do whatever you want."

Since the discovery of C72 fullerene, the entire Fullerene Research Institute has been strictly guarded.

Everyone who leaves the Fullerene Research Institute will be searched.

Including Professor Gao and Ye Fei.

No one is allowed to take C72 Fullerene out of the Institute.

The young man said: "Got it, got it."

Ye Fei stared at the mask on the young man's hand, lost in thought.

Seeing Ye Fei staring at the mask on his hand, the young man smiled and said, "Director Ye, do you want it? If so, I'll make some for you."

Professor Gao said: "Ye Fei, don't mess around with him, you are not that kind of person."

Professor Gao thinks this behavior is too motherly, what kind of mask is a big man wearing!

The rest of the people have the same idea.

Ye Fei nodded and said, "Okay!"

Everyone looked at Ye Fei in astonishment, speechless in their hearts, they didn't expect Ye Fei to be this kind of person, they misread you.

The young man smiled and said, "Haha... Director Ye and I have a common language. Director Ye, what skin care products do you usually use?"

Ye Fei said, "Da Bao!"

"Dabao?" The young man was stunned for a moment: "See you every day?"

Does anyone still use Dabao at this time?
Dabao is an old brand of skin care products in Xiaguo. Many post-[-]s and post-[-]s used Dabao when they were young.

Dabao sees you every day. In the 90s of the last century, it was almost a well-known slogan.

Ye Fei said: "Bring me the mask on your hand to see the effect."

"Are you using it now?" The young man asked in surprise, "Isn't it appropriate to use it here?"

Ye Fei said: "Stop talking nonsense, bring it quickly."

"Okay!" The young man handed the mask to Ye Fei and said, "Director Ye, do you want me to help you?"

"No need!" Ye Fei shook his head.

After speaking, Ye Fei put the mask into a cylindrical transparent glass box, and then turned on the switch.

The young man looked at Ye Fei in astonishment and said, "Director Ye, what are you doing?"

Ye Fei didn't speak, just stared at the computer screen.

The rest of the people also looked at Ye Fei curiously.

At this time, data is generated on the computer screen.

Ye Fei's eyes widened in surprise in an instant, and he stared at the computer screen tightly.

The rest of the people were attracted by Ye Fei's behavior and gathered around Ye Fei.

Professor Gao said in surprise: "Electrolyte ions have actually passed through."
