Chapter 288 Qin Anguo: "What if it was you who took action?"
After answering some questions, Xu Chuan announced the end of the press conference.
In the lecture hall, the manufacturers who came to attend the press conference were stunned.
Is this the end?
What about the patent authorization for the artificial SEI film later?
Where have you gone? Don't do it anymore?
Many manufacturers who came from afar were stunned and watched Xu Chuan leave.
After 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 held after the press conference.
In fact, not every manufacturer who comes to the conference is qualified to participate in the patent licensing competition for artificial SEI films.
Xu Chuan did not intend to make it an auction-like event and conduct it in public.
Those who are eligible to compete for artificial SEI film patent authorization have been selected in advance and have received the first batch of invitations.
The lithium battery industry is still quite large, and it can be considered a sustainable development industry.
After all, areas such as mobile phones and cars that consume a large amount of batteries are almost always replaced every year or every few years.
Therefore, Xu Chuan doesn't really want to mess up this market. Cooperating with a group of high-quality manufacturers is the best choice.
Of course, it is not that there are no manufacturers who want to monopolize the patent authorization of artificial SEI films, whether domestic or foreign.
After all, monopoly can obtain the greatest benefits.
In the past, some manufacturers came to the door and were willing to buy the exclusive patent license for five years at a price of 3 billion meters.
Three billion meters of 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. Monopoly can indeed allow him to gain a large amount of patent fees, even much higher than normal multiple licenses.
But this method also means losing competition. They have the final say on how much the battery will be sold in the future, which is not friendly to consumers and the market.
A stagnant lithium battery industry without vitality is not what he wants to see.
Therefore, Xu Chuan has prepared a total of five places for this patent authorization.
This will ensure that the entire market has enough competitive vitality, and ordinary people will not waste money on expensive batteries.
After all, there are competitors, and if your price 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. Compared with capitalists earning profits without humanity, he would rather see his research or inventions being put to good use.
In the afternoon, Xu Chuan met the invited representatives of various manufacturers in the conference room.
All well-known international battery manufacturers at home and abroad, including CATL, Panasonic, LG Chem, and BYD, have been invited here.
Naturally, it is not easy to negotiate such a big deal.
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 are also industrial production cost estimates for artificial SEI films, which are all related to patent licensing quotations.
Xu Chuan did not waste too much time on this. He met with the staff of these battery manufacturers once, and after briefly chatting about some core things, he left this matter to professionals.
Negotiation is not his strong suit.
Once the patent license for the artificial SEI film is sold, the Sichuan-Hai Materials Research Institute will be able to expand.
Whether it is the recruitment of scientific researchers, the change of venues, or the research and development of new materials, it can all be carried out.
The current Sichuan-Hai Materials Research Institute is still too small.
Many equipments are not available, and some subsequent experiments cannot be carried out.
After settling the matter of patent authorization for the artificial SEI film, Xu Chuan sent a message to Zheng Hai and asked him to help book a ticket to Qidong.
It is now the end of May, and the Nuclear Energy Research Institute has also entered into the final work. Thanks to the solution he came up with last time, the energy level and stability of the linear particle accelerator have been solved, and it is now on the 24th. Construction continues hour after hour.
According to Han Jin's report, it is expected that the nuclear waste power station will be able to start the first round of complete testing in about fifteen days.
It's time for him to go over and take charge of 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, so he walked out. There were two middle-aged men standing at the door of the courtyard, and one of them was Qin Anguo, who was very familiar with science and technology.
"Professor Xu, you came uninvited, I'm sorry for disturbing you."
In the courtyard, Qin Anguo greeted Xu Chuan with a smile.
"How could it be? It's too late to welcome them. Come in quickly." Xu Chuan opened the door with a smile and welcomed the two of them into the villa.
"Come on, Professor Xu, let me introduce to you. This is the head of our country's energy management department, Wang Guanghe"
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 all work to serve the people and the country, regardless of high or low."
"I have often heard your name, Professor Xu, mentioned for a long time. When I saw it today, it is indeed well-deserved. It is a blessing for our country to have a scholar like you."
On the side, Wang Guanghe smiled and enthusiastically held Xu Chuan's hand and said with a smile. He looked like an old man who wandered around the community after retirement, without any sense of arrogance or majesty.
Xu Chuan smiled and shook hands with the big boss in front of him, and said modestly: "You are exaggerating, I just made a small contribution."
In the living room, the three of them exchanged pleasantries before getting down to business.
Qin Anguo said: "I came here to disturb you, Professor Xu, mainly because of the artificial SEI film and lithium batteries."
Hearing this, Xu Chuan looked at Qin Anguo doubtfully.
Artificial SEI film has been known for a long time. When he applied for a domestic patent last year, Qin Anguo called him to inquire about it.
When he went to Beijing to talk to the old man about controllable nuclear fusion 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 licensing of artificial SEI films.
Otherwise, the higher-ups would have come looking for such a big movement.
In China, 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 from state-supported scientific research projects to your own company or research institute laboratory, there will be no problem.
"Ahem, Professor Xu, don't get me wrong. I am not here to interfere with your choice. Regarding the artificial SEI film you developed, we absolutely support all your legitimate rights and interests, whether it is domestic or foreign patent authorization. ”
Noticing Xu Chuan's confused gaze, Qin Anguo quickly explained.
On the side, Wang Guanghe said: "Chief Qin and I came here this time mainly because we want to discuss with you the future of lithium batteries and the future development of the domestic energy field."
Xu Chuan shook his head and said: "If you have any problems in scientific research, maybe I can help."
"But the future of lithium batteries and the future development of the energy field, which are related to 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 reuse project you led or the research on artificial SEI thin films, they have had a major impact and change on the energy field and battery field. In the energy field, you Already one of the best authorities.”
Xu Chuan blushed and said: "In the final analysis, these are actually scientific research matters, and they 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 did, he would still be happy to talk about his views.
But forget about the things you don’t understand.
Sometimes one sentence can mislead the development of things. If he leads the country's energy development layout astray, then he is really a sinner.
On the side, Wang Guanghe said: "Let me tell you."
After a pause, he pondered for a moment and then looked at Xu Chuan and said, "Professor Xu, you should know very well that our country is currently the largest energy consumption market in the world,
"The crisis in the energy field has always been a concern for our country. With development, the amount of domestic oil consumed is also increasing."
"In 2018, last year, according to statistical reports, the net oil import volume in 2018 reached an astonishing 440 million tons, an increase of 11% year-on-year in 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 freely slaughtered."
"The fall and rise of international oil prices are all controlled by others. The increasing dependence on foreign oil and gas has become a huge challenge facing our country's current energy consumption."
“So seeking changes in the energy structure has always been something we want to do and are doing.”
"Including vigorously promoting various power generation methods such as solar energy, wind energy, and nuclear energy, as well as actively promoting the development of new energy vehicles, etc., we actually hope to reduce some dependence on petroleum energy."
"In fact, from a national level, the impact of the patent on the artificial SEI film that solves the problem of lithium dendrites cannot be described in terms of 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, cars, or other fields, there will be major changes."
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 and opinions on the future development of lithium batteries."
"Including how to research lithium batteries in the future, whether it is lithium-sulfur batteries or lithium-air batteries, or other directions, etc."
At this point, Xu Chuan understood what they wanted to ask.
I just want to ask if there is any hope of surpassing those Western countries such as Britain and America in the field of lithium batteries.
Competition between countries is ubiquitous, especially in the frontier fields of science and technology, from lithography machines to aerospace, from bioscience to materials chemistry, etc. Each country has its own development.
Lithium batteries, which have never been fully mature, are something that Huami, East Asia and other countries around the world are studying
Especially now that the lithium dendrite problem has been solved by him in advance, the development of lithium batteries has branched off 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 we just talk about this, he can still give some opinions.
Heaving 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: "You said it."
Xu Chuan pondered for a moment 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 lithium-sulfur batteries or lithium-air batteries, they need to be based on these three basic factors."
"I know 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 researching lithium-sulfur batteries, and our country started relatively late."
"But how should I put it, I actually recommend doing it step by step."
"It is undeniable that the energy density of lithium-air batteries is quite high, even comparable to that of petroleum, but there are too many problems that need to be solved."
"The lithium dendrite problem is just one of a kind."
"For example, the reaction kinetics of lithium-air batteries on the positive electrode is a problem because the discharge products of the positive electrode are solid Li2O2 and other materials, which are insulating and will cause the positive electrode reaction kinetics to be slow. This leads to low energy density and short cycle life. , poor rate performance, low energy efficiency and other problems. ”
"There are also intermediates formed during the electrochemical process, lithium superoxide and lithium peroxide, which will degrade the battery from the inside, greatly limiting the battery cycle life and other issues."
"These are quite difficult to solve."
Regarding these, Xu Chuan did not tell lies.
I have to admit that the energy density of lithium-air batteries is indeed very attractive. Its theoretical specific energy can reach 11.4kWh/kg, which is comparable to oil combustion.
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 existed only in PPT files or in laboratories.
This isn't just a problem with lithium dendrites.
It is a series of complex oxidation reactions, including how to separate pure oxygen from the air at low cost, including the production of lithium oxide, which will reduce battery life and so on.
These are no less difficult problems than lithium dendrites, or even more difficult.
After recording Xu Chuan's opinions with a pen in his notebook, Qin Anguo raised his head and couldn't help but ask: "What if it was you who took action? Is there any hope of solving these problems?"
