The president of Jinling University said he would do it, and after the dean left, he called Ye Fei.

The president sat in the office chair, held the phone and said with a smile: "Hey, hello, is it Dean Ye, I am 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 of the airport.

After Ye Fei finished arranging the work of the Meta Blockchain Research Institute, he went to the Kyoto Graphene Research Institute.

The research of the Meta Blockchain Research Institute does not have to be done personally, and the core research has been developed.

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

Unless the people under him can't succeed in research, or need to accelerate research, Ye Fei will start it himself.

But with the current situation, the meta-blockchain system does not have any competitors in the world, so there is no need to rush to research.

Ye Fei put more energy into mathematical research and fullerene.

After C72 fullerene was discovered, Ye Fei also wanted to know what applications C72 fullerene could have.

Yuan Xiang said with a smile: "Dean Ye, you see that a great genius like you has come to Jinling, you should come to Jinling University to sit down!" ”

Ye Fei said with a smile: "President Yuan, you have won the award, I am not a great genius, as a native of Jinling, Jinling University has always been a university I admire, and I will sit there when I have the opportunity." ”

"When will there be a chance?" Yuan Xiang was overjoyed in his heart, and said with some urgency: "Is it okay recently?" ”

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

Yuan Fei felt a little lost in his heart, and asked, "What are you busy with, maybe our school can provide some meager strength." ”

Ye Fei smiled and said, "I'm not busy, I'm busy!" ”

Yuan Fei shook his head and chuckled: "If you are all busy, then others are even more busy." ”

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

If Ye Fei's research is all busy, then what are the rest of the researchers busy with every day?

Ye Feidao: "Recently, I have mainly done two jobs, research in the field of mathematics and materials. ”

"Oh, yes!" Yuan Fei patted his head and looked suddenly realized: "You have 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." ”

"Okay."

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

Yuan Fei has always wanted to talk to Ye Fei face-to-face, but he didn't have the opportunity every time.

Either Ye Fei is not in Jinling, or Ye Fei is very busy and has no time to talk.

This time was the same, Ye Fei was too busy, and the two didn't have a chance to talk.

Yuan Fei secretly cheered himself up and said, "It's okay, there are many good things, a talent like Ye Fei is a normal thing." ”

"This time it doesn't work, there will be a next time, next time it won't work, and there will be a next time."

Airport, VIP Lounge!

Ye Fei put the mobile phone in his pants pocket, and then picked up the tea in front of him and drank it slowly.

"Hello, it's Dean Ye!"

At this time, a middle-aged man walked up to Ye Fei's side.

The middle-aged man is about 1.75 meters tall, wearing a black suit, with a round face and a friendly smile.

Behind the middle-aged man, followed by a young man of about thirty years old wearing a black suit.

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

The young man was carrying a black leather bag in his hand, looking like a middle-aged man's subordinate.

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

The middle-aged man stretched out his hand and said with a smile: "The contemptible person is Xu Li, chairman of Enjie Co., Ltd." ”

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

Many people may not have heard of the company.

The main business of the company is to provide a variety of packaging and printing products, packaging products and services, as well as lithium battery separator film, aluminum-plastic film and water treatment film.

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

Xia Guo is the largest sales market for new energy vehicles, and the company should develop very well.

It's just that the lithium battery separator has not developed well in any company in Xia, and there is a big gap compared with the world.

The same is true for the company, in the many businesses of the company, the lithium battery separator is the worst, and even reaches the point of loss.

But the short man is tall, and the lithium battery separator of the company is the best developed among all the companies in Xia Guo.

Almost all lithium battery separators of lithium battery companies in Xia are imported from abroad.

Xu Li smiled: "Can I sit down?" ”

"Of course!" Ye Fei smiled: "Please!" ”

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

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

Xu Li said with a smile: "I have heard of Dean Ye's name for a long time, and I used to see it in the news and on the Internet, but today I finally saw me." ”

Ye Fei shook his head and smiled: "Mr. Xu has won the award." ”

"Mr. Xu, I have seen the report of the company before, but I have a big doubt."

"You want to ask, why didn't our company cut the lithium battery separator business, right?"

Ye Fei nodded and said, "Yes." ”

"Actually, it's not just you who ask me, many people ask me that." After Xu Li took a sip of the tea in front of him, he looked at the flow of people coming and going outside the glass.

"In the field of lithium batteries, there are four main materials, namely cathode materials, anode materials, electrolytes and separators."

"The first three have been conquered by our country, and they can be manufactured to reach the international average."

"Only the separator, China's lithium electronic separator technology, lags behind the international level."

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

"If my company gives up the lithium battery separator, then when will Xia Guo be able to manufacture a lithium battery separator that is comparable to the international level?"

"Even if our company loses money, we must insist on the research and development of lithium battery separators, and we cannot cut off the lithium battery separator business."

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

There are very few companies that would rather lose money than stick to this business, just so that their own country has this technology.

In terms of interests, this is stupid.

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

It is hoped that one day, the country will be able to develop this technology that is comparable to the international level.

Ye Fei said with a smile: "Mr. Xu, one day, we Xia Guo will be able to manufacture a lithium battery separator that is comparable to the international level." ”

Xu Li smiled bitterly: "Hope! ”

Xu Li has insisted on this idea for many years, many times it has brought him hope and many times it has brought disappointment.

The more hopes, the more disappointments!

But Xu Li was still unwilling to give up.

He didn't know what the future was waiting for.

But all he is holding on to now is a 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, "After so many years, maybe success is not far away." ”

After each sentence, he continued to persevere.

Xu Li is like an island keeper, guarding the most cutting-edge territory in the field of lithium battery separators in Xia Kingdom.

Equivalent to a tech goalkeeper!

【Please board for passengers flying from Jinling to Kyoto!】 】

At this time, the voice of boarding is played on the radio.

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

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

Xu Li smiled: "Okay." ”

After speaking, the two added WeChat to each other.

"Goodbye!" Ye Feidao.

"Goodbye!"

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

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

Ye Fei couldn't help but laugh and said, "I've only been gone for a long time, and I'm going to Jinling to tie me up." ”

"Our research is important, and in your absence, we have one less main force."

Professor Gao pulled Ye Fei and walked quickly towards the research institute and said, "I'll show you what we have made with C72 fullerene during this time." ”

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

There are many researchers working on the lab in the lab.

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

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

"Its performance is about two times stronger than that of C60's water-soluble fullerene."

Ye Fei said in surprise: "So high? ”

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

"I just changed the fullerene from C60 to C72, but the water-soluble fullerene produced was twice as much as C60."

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

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

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

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

"Based on the properties of C72, we have developed C72 non-fullerene, which is an acceptor photovoltaic material for C72 non-fullerene."

Fullerenes and non-fullerenes are two opposite things.

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

Ye Fei picked up the receptor photovoltaic material with his left hand, and it felt very thin and light when he picked it up, much lighter and thinner than the C60 non-fullerene receptor photovoltaic material that Ye Fei had been exposed to before.

Ye Fei grabbed the other side of the recipient photovoltaic material with his right hand and bent it hard, and after the photovoltaic material was bent to 90 degrees, there was no crack.

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

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

And the material itself has low manufacturing cost, light weight, translucency, and strong flexibility.

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

Professor Gao smiled and nodded, "Yes, do you know what its weight and flexibility are?" ”

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

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

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

The receptor photovoltaic material on Ye Fei's hand is 400 square centimeters, that is, a square with a side length of 20 centimeters.

If it is a C60 non-fullerene acceptor photovoltaic material, such an acceptor photovoltaic material has a mass of about four catties and a flexibility of 70 degrees.

"yes!" Professor Gao nodded.

Ye Fei said: "How much heat energy can be absorbed?" ”

Professor Gao said: "Such an acceptor photovoltaic material, one meter long and wide, can absorb 300 watts in an hour and 2,500 watts in a day when the sun is at its strongest. ”

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

You must know that even C60 receptor photovoltaic materials can absorb up to 100 watts of electricity in an hour when the sun is at its strongest.

Professor Gao added: "It can absorb 300 watts in an hour and 2,500 watts in a day. ”

Ye Fei suppressed the surprise in his heart and said: "If you say so, the solar photovoltaic panels made by C72 non-fullerene only need sixteen cubic meters of absorbed solar energy, which can meet the needs of a family for a day." ”

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

Professor Gao nodded, "Yes!" ”

Ye Fei smacked his tongue and exclaimed: "This is too strong, Professor Gao, this thing can be popularized, so that every household can use it, after all, as long as a sixteen cubic meter solar photovoltaic panel, it can meet the electricity consumption of a family for a day." ”

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

"After all, there are many buildings in the city, and there are few flats and villas."

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

"Hmm!" Ye Fei nodded and smiled: "Indeed, I took it for granted, this thing is not suitable for the city, only for the countryside." ”

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

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

"The state has always advocated this way of generating electricity."

"Yes!" Ye Fei nodded: "But Professor Gao, the biggest property of fullerene is antioxidant, so we should start from this aspect." ”

"You're talking about it!" "This is also the focus of our next research, and we need to consider what aspects of antioxidant to start with. ”

"If you start with skin care products and preservative materials, it's a bit overkill."

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

Ye Feidao: "Have you ever thought about lithium battery separator materials?" ”

Ye Fei remembered the Xu Li he met at the airport, Xu Li has 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 the four core materials in the field of lithium batteries.

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

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

"Lithium battery separator?" Professor Gao was stunned for a moment.

Then he shook his head and smiled bitterly: "Ye Fei, I should have taught you at that time, fullerene can't work in the field of lithium batteries." ”

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

"Why don't you try to do some research?" Ye Fei said: "After all, what you are talking about is the knowledge of C60 fullerene. ”

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

Ye Fei felt that since fullerenes could isolate oxygen, maybe they could also isolate other things.

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

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

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

Professor Gao nodded and said, "Okay, then study and see, but I can't guarantee whether there will be any new discoveries." ”

Ye Fei said with a smile: "Try it, maybe you can make new discoveries." ”

Next, Ye Fei and others began to put themselves into work.

In the lab!

Ye Fei sat 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 held an electric pen in his hand to contact the receptor photovoltaic material.

At the same time, Ye Fei looked at the electricity meter on the side to see if the pointer on it moved.

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

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

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

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

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

"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 case is connected to the computer.

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

A lot of data is 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 fullerene really can't be used in the field of lithium batteries." ”

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

Professor Gao looked at the young man and said helplessly: "You kid, you use fullerene to whiten again, let's study fullerene, is it to make people beautiful?" ”

The young man smiled: "I use leftover materials, and you don't use those leftovers, so you should throw them away when the time comes, why don't I use them to make something I like." ”

Professor Gao waved his hand irritably: "Do it, do it, as long as you don't take out the research institute." ”

Since the discovery of C72 fullerene, the entire fullerene research institute has been tightened.

All those who leave the Fullerene Institute are to be searched.

Including Professor Gao and Ye Fei.

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

The young man said, "I know, I know." ”

Ye Fei stared at the mask on the young man's hand and fell into thought.

The young man saw Ye Fei staring at the mask on his hand, and said with a smile: "Director Ye, do you want it?" I'll make you some if you want. ”

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 does a big man wear!

The rest of the people thought the same way.

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 misjudged you.

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

Ye Fei said: "Dabao! ”

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

At this time, there are still people who use Dabao?

Dabao is an old brand in Xia Guo's skin care products, and many post-90s and post-95s generations used Dabao when they were children.

Dabao sees every day, in the nineties of the last century, it was almost a household name advertising slogan.

Ye Fei said: "Take the mask in your hand to me to see the effect." ”

"You're going to use it now?" The young man was surprised and said, "It's not appropriate to use it here!" ”

Ye Fei said: "Don't talk nonsense, hurry up and bring it." ”

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

"No!" Ye Fei shook his head.

After speaking, Ye Fei put the mask into the 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 instantly, staring at the computer screen tightly.

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

Professor Gao was surprised: "The electrolyte ions actually passed. ”
