Great Country Academician

After answering some questions, Xu Chuan announced the end of the press conference.

In the lecture hall, the manufacturers who came to the press conference were all stunned.

This is the end?

What about the patent authorization of the artificial SEI film?

Where did you go? Don't do it?

Many manufacturers who came from afar were stunned and watched Xu Chuan leave.

After finishing the press conference, Xu Chuan returned to the backstage.

There was indeed a patent licensing auction for artificial SEI films after the press conference, but he never said it would be after the press conference.

In fact, not every manufacturer who comes to the conference is eligible to participate in the patent licensing competition for artificial SEI thin films.

Xu Chuan didn't intend to make it an auction, and hold it in public.

Those who are eligible to compete for the patent authorization of artificial SEI thin films have been selected in advance and have received the first batch of invitation letters.

The lithium battery industry is still quite large, and it can be regarded as a sustainable industry.

After all, mobile phones, cars and other fields that consume the most battery are almost replaced every year or several years.

So Xu Chuan didn't really want to mess up the market, and it was the best choice to cooperate with a group of high-quality manufacturers.

Of course, it is not that there are no manufacturers who want to monopolize the patent authorization of artificial SEI films, whether they are domestic or foreign.

After all, monopoly can obtain the greatest benefit.

In the past, there were manufacturers who took the initiative to come to the door, willing to buy the exclusive patent license for five years at a price of 3 billion rice.

Three billion rice gold, almost 20 billion RMB in five years, this bid is quite high.

But Xu Chuan still refused.

He doesn't like this method very much. The monopoly can indeed earn him a lot of patent fees, even much higher than the normal multi-authorization.

But this method also means losing competition, and how much the battery will sell in the future will be up to them, which is not friendly to consumers and the market.

A stagnant and lifeless lithium battery industry is not what he wants to see.

So for this patent authorization, Xu Chuan has prepared a total of five places.

This can ensure that the entire market has sufficient competitive vitality, and ordinary people will not spend unreasonable money on expensive batteries.

After all, there are competitors, and if the price you sell is too high, consumers will naturally choose other manufacturers.

Although decentralized licensing will reduce patent licensing fees a lot, the stability and competitiveness of the market, as well as the rights and interests of ordinary consumers, are what Xu Chuan considers.

He is not a capitalist, but a scientist. He would rather see his research or inventions being put to good use than capitalists earning profits inhumanely.

In the afternoon, Xu Chuan met the invited representatives of various manufacturers in the meeting room.

CATL, Panasonic, LG Chem, BYD and all well-known international battery manufacturers at home and abroad were invited to come here.

Naturally, such a large deal is not so easy to negotiate.

Although these manufacturers have tested the performance of artificial SEI films, due to time constraints, these battery companies have not had time to integrate samples of new artificial SEI films for complete testing.

There is also the estimation of the industrial production cost of the artificial SEI film, which is related to the quotation of patent authorization.

Xu Chuan didn't waste too much time on this. He met with the personnel of these battery manufacturers once, and after briefly chatting about some core aspects, he left this matter to professionals.

Negotiations are not his forte.

After the authorization of the artificial SEI thin film patent is sold, Chuanhai Materials Research Institute can be expanded.

Whether it is the recruitment of scientific research personnel, the replacement of venues, or the research and development of new materials, it can all be carried out.

The current Chuanhai Materials Research Institute is still too small.

A lot of equipment is not available, and some subsequent experiments cannot be done.

After dealing with the patent authorization of the artificial SEI film, Xu Chuan sent a message to Zheng Hai, asking him to book a ticket to Qidong.

It is now the end of May, and the Institute of Nuclear Energy has also entered the finishing work. Thanks to the solution he came up with last time, the energy level and stability of the linear particle accelerator have been resolved. Hours of non-stop construction.

According to Han Jin's report, it is estimated that in about fifteen days, the nuclear waste power station will be able to start the first round of complete testing.

It is also time for him to go over and preside over the overall situation.

As soon as the message in his hand was sent, the doorbell of the villa rang in the room.

Xu Chuan was a little curious about who could come here by such a coincidence, and walked out. There were two middle-aged men standing at the gate of the courtyard, and one of them was Qin Anguo, who was familiar with science and technology.

"Professor Xu, come here uninvited, I'm sorry to bother you."

In the courtyard, Qin Anguo greeted Xu Chuan with a smile.

"Why, it's too late to welcome, please come in." Xu Chuan opened the door with a smile, and welcomed the two into the villa.

"Come here, Professor Xu, let me introduce you, this is Wang Guanghe, the leader of our country's energy management department."

Qin Anguo smiled and introduced the middle-aged and elderly men around him.

"Don't listen to Lao Qin's nonsense. The first and second leaders are all working for the people and the country, regardless of high or low."

"Professor Xu has often been mentioned by people for a long time. Today, seeing you, you really deserve your reputation. It is a blessing for our country to have a scholar like you."

On the side, Wang Guanghe held Xu Chuan's hand enthusiastically with a smile and said with a smile, he looked like an old man strolling in the community after retirement, without any airs or majesty.

Xu Chuan shook hands with the big man in front of him with a smile, and said modestly: "You are too famous, I just made a trivial contribution."

In the living room, after the three exchanged pleasantries, they began to get down to business.

Qin Anguo said: "This time I took the liberty to come here to disturb you, Professor Xu, mainly because of the artificial SEI thin film and lithium battery."

Hearing this, Xu Chuan looked at Qin Anguo suspiciously.

The artificial SEI film has been known for a long time.

When he applied for the domestic patent last year, Qin Anguo called him to inquire about it.

When he went to Beijing to talk about controllable nuclear fusion with the old man at the beginning of the year, he also talked about this aspect, including some developments in the domestic energy and lithium battery industries, and the authorization of artificial SEI thin films.

Otherwise, for such a big movement, the higher-ups would have found it long ago.

Domestically, university professors or scholars are allowed to open their own companies or research institutes while leading or participating in state-supported scientific research projects.

As long as you don't transfer the resources of the state-supported scientific research projects to your own company or research laboratory, there is no problem.

"Hey, Professor Xu, don't get me wrong. I came here today not to interfere with your choice. Regarding the artificial SEI film you developed, whether it is a domestic or foreign patent authorization, we absolutely support all your legal rights. "

Noticing Xu Chuan's puzzled gaze, Qin Anguo quickly explained.

On the side, Wang Guanghe said: "I came here this time with Mr. Qin, mainly to discuss with you the future of lithium batteries and the future development of the domestic energy sector."

Xu Chuan shook his head and said, "If there is any problem in scientific research, maybe I can help."

"However, the future of lithium batteries and the future development of the energy field, which involve national strategic development, are not in my research field. Mr. Wang, you have found the wrong person."

Qin Anguo smiled and said: "Professor Xu, you are too modest. Whether it is the nuclear waste recycling project you led or the research on artificial SEI films, they have had a major impact and change on the energy field and the battery field. In the energy field, you Already one of the best authorities."

Xu Chuan blushed, and said: "In the final analysis, these are all scientific research matters, and are completely different from the development and future of the energy field."

He is not refusing, it is true that he does not understand this aspect, if he understands, he is still happy to talk about his views.

But if you don't understand something, forget it.

Sometimes a single sentence can mislead the development of things. If he misleads the energy development layout of the motherland, he is really a sinner.

On the side, Wang Guanghe said, "Let me tell you."

After a pause, he pondered for a moment, looked at Xu Chuan, and said, "Professor Xu, you should be very clear that our country is currently the largest energy-consuming market in the world.

"The crisis in the energy sector has always been a concern for our country. With development, the amount of domestic oil consumption is also increasing."

"In 2018, that is, last year, according to statistical reports, the annual net oil imports in 2018 reached an astonishing 440 million tons, an increase of 11% compared with 2017, and the dependence on foreign oil energy also rose to 69.8%."

"When more than 70% of a material depends on imports, it can be said that this material is almost allowed to be slaughtered."

"The rise and fall of international oil prices is entirely under the control of others. The increasing dependence on foreign oil and gas has become a huge challenge for our country's current energy consumption."

"So seeking to change the energy structure has always been what we want to do and are doing."

"Including vigorously promoting various power generation methods such as solar energy, wind energy, and nuclear energy, and actively promoting the development of new energy vehicles, etc., in fact, it is also hoped to reduce some dependence on oil energy."

"In fact, at the level of a country, the patent of the artificial SEI thin film that solves the problem of lithium dendrites has such a great impact that it cannot be described by money."

"Because with the breakthrough of lithium battery technology, it is foreseeable that the domestic lithium battery industry will usher in vigorous development. Whether it is daily necessities such as mobile phones and automobiles, or other fields, major changes will occur."

After a pause, Wang Guanghe continued: "And more importantly, because of your existence, our country has been at the forefront of the world in the field of lithium batteries for the first time."

"So we hope to hear your opinions on the future development and opinions of lithium batteries."

"Including how to study lithium batteries in the future, whether it is lithium-sulfur batteries or lithium-air batteries, or other directions, etc."

Speaking of this, Xu Chuan understood what they wanted to ask.

I just want to ask if there is any hope of surpassing those western countries in the field of lithium batteries.

Contests between countries are everywhere, especially in frontier fields of science and technology, from lithography to aerospace, from biological science to material chemistry, etc., and each country has its own development.

The lithium battery, which has not been fully matured, is something that Huami, Europe, East Asia and other countries in the world are studying.

Especially now that the lithium dendrite problem has been solved in advance by him, the development of lithium batteries has been divided into several different routes.

Lithium metal batteries, lithium ion batteries, lithium sulfur batteries, lithium air batteries, etc., all have their own advantages and disadvantages.

If it's just talking about these, he can still give some opinions.

Breathing a sigh of relief, Xu Chuan smiled and said, "If that's the case, I can say a few words."

Hearing this, Qin Anguo and Wang Guanghe immediately sat up straight, and said in unison, "Say it."

Xu Chuan pondered for a while, and then said: "I probably know what you are thinking."

"The three key factors for the development of lithium-ion batteries are nothing more than three, high safety, high energy density, and low cost."

"This is the future development trend of lithium batteries. Whether it is a lithium-sulfur battery or a lithium-air battery, it needs to be based on these three basic factors."

"I know that you must have done your own research. Perhaps because of various issues such as patents, you are more inclined to lithium-air batteries in the current blank area. After all, there are many laboratories for lithium-sulfur battery research, and our country started relatively late."

"But how to put it, I actually suggest to do it step by step."

"It is undeniable that the energy density of lithium-air batteries is quite high, even comparable to petroleum, but there are too many problems to be solved."

"The lithium dendrite puzzle is just an ordinary one."

"For example, the reaction kinetics of lithium-air batteries on the positive electrode, because the discharge product of the positive electrode is solid Li2O2 and other materials, which are insulating, which will lead to slow reaction kinetics of the positive electrode. This leads to low energy density and short cycle life. , poor rate performance, low energy efficiency and other series of problems.”

"There are also intermediates formed in the electrochemical process, lithium superoxide and lithium peroxide will degrade the battery from the inside, which greatly limits the cycle life of the battery and so on."

"These are pretty difficult to resolve."

Regarding these, Xu Chuan did not lie.

It has to be admitted that the energy density of lithium-air batteries is indeed very attractive, and its theoretical specific energy can reach 11.4kWh/kg, which is comparable to burning oil.

In the face of attractive prospects, lithium-air batteries face far more problems than lithium-ion batteries and lithium-sulfur batteries.

But even before rebirth, lithium-air batteries still only exist on PPT files or things in the laboratory.

It's not just a problem with lithium dendrites.

It is a series of complex oxidation reactions, including how to separate pure oxygen from air at a low cost, including the production of lithium oxide, which will reduce battery life and so on.

Both are no less difficult problems than lithium dendrites, or even harder.

After recording Xu Chuan's opinions in the notebook with a pen, Qin Anguo raised his head and couldn't help but ask, "What if you do it? Is there any hope of solving these problems?"
