Chapter 271 Genius is not enough to describe me
In the small conference room, the atmosphere became quiet after Academician Chen Quan took the initiative to mention Wang Donglai’s name.
Because the people present were either university professors or company executives, even secretaries and reporters were among the best.
As soon as Academician Chen Quan said his words, everyone was keenly aware of the appreciation for Wang Donglai in Academician Chen Quan’s words.
Although it seems inappropriate for Academician Chen Quan to ask Wang Donglai at this time, if you think about it carefully, you will find that this is a good opportunity.
After all, there are many industry leaders who can attend this conference, including professors and scholars from universities, and engineers who have specialized in the new energy field for many years.
If everyone wanted to speak, Wang Donglai would definitely be at the back of the queue.
Of course, this situation will not happen.
But Wang Donglai’s status in this conference is not high in the field of new energy, but this is true.
Academician Chen Quan directly asked Wang Dong to explain his thoughts and views, which undoubtedly gave him a good opportunity to express his views.
Wang Donglai can naturally understand this.
As for why Academician Chen Quan helped him, he also had a rough guess in his mind.
In just a few breaths from when he was asked to speak to when Wang Donglai stood up, he had already thought about what he should say.
“The ideas and research directions of several professors are extremely practical, whether it is developing new materials, optimizing process flows, or improving battery technology, using lithium-sulfur batteries and lithium iron carbonate batteries and Lithium batteries are all attempts. I think there is no need for the academic community to have a unified view at this time. point to promote a certain technology.”
“Every technology has its advantages and disadvantages. Our country is in a complicated situation. Only the market can give the best and most appropriate answer. Our opinion is to go hand in hand and work together to complete the technical breakthrough of the new energy market.”
If Wang Donglai had no plug-ins and didn't know the future development, he might really not know the development direction of new energy.
However, even though he knows it, it doesn't mean that he will say it casually.
If the king is not secretive, his ministers will lose; if the ministers are not secretive, they will lose their virginity; if the secret is not secret, it will cause harm. This is why a gentleman keeps his secrets and does not go out.
Wang Donglai still understands this truth very well.
That’s why he gave this snake oil answer.
The main thing is that no one should be offended and no one should be criticized.
The purpose of his coming to this meeting is not to express himself, but to listen to other people's ideas and concepts here so as to gain inspiration and complete a breakthrough.
He can still tell clearly which one is more important than the other.
However.
Wang Donglai’s answer did not achieve the desired effect.
Not to mention the other people's expressions of disdain, even cynicism.
Academician Chen Quan, who was sitting at the main seat, kept his expression unchanged and asked with a warm smile: "Professor Wang is right, all technologies must be market-oriented, and we are In countries with complex geographical conditions, the development of the new energy industry is impossible It will be a model, which will inevitably require the coexistence of multiple technologies, and then the market will determine the best new energy technology development route.”
“However, this time is not only a meeting for everyone to discuss and exchange, but also an organizational one. A visit to the new energy industry For research activities, the National Scientific Research Fund is limited and can only choose some projects with greater possibilities and better development prospects. Therefore, Professor Wang might as well talk about the technologies he is most optimistic about and which development route is the most promising. The reason is What?”
"I have seen two papers you wrote in "Advanced Materials" before, and I think your talent in this area is no less than in the field of mathematics."
Academician Chen Quan said In the end, he still revealed why he was optimistic about Wang Donglai.
This explanation also made other people present suddenly realize, and then all their eyes looked at Wang Donglai.
Especially the engineers from CATL and BYD looked at Wang Donglai with bright eyes.
The two of them still knew very well about Wang Donglai’s breakthrough in lithium batteries.
Now, when Academician Chen Quan said this and everyone looked over, Wang Donglai was a little surprised.
However, it only took a moment for him to speak: "From the perspective of battery materials, there are mainly several types, including lithium iron phosphate, lithium batteries, and other battery types. From the manufacturing point of view, In terms of craftsmanship, it is also different.”
"So, in my opinion, the most promising and promising route is actually a false proposition."
"There is no best, only the most suitable!"
"The development of lithium-sulfur batteries There are many advantages, but there are also many shortcomings. If the shortcomings can be overcome, then lithium-sulfur batteries will definitely be the most promising battery route."
"The same is true for lithium batteries, whose performance is far beyond that. Lithium iron phosphate batteries have a wider range of applications, but they also have their drawbacks. "
"As far as I know, the current research directions for new energy batteries around the world are these, but they are preset. There are many prospects for the future, whether it is micro controllable nuclear batteries, graphene batteries, or high-efficiency solar charge and discharge batteries, they are all preset assumptions for the future. ”
"Returning to the topic, currently, in terms of new energy batteries, I am studying solid-state batteries. I think solid-state batteries are the most appropriate development route from multiple dimensions such as technological prospects, ease of implementation, large-scale production, and safety. !”
After talking a lot, Wang Donglai finally gave his research direction.
Everyone at the scene suddenly had different expressions when they heard that Wang Donglai’s most promising new energy battery direction turned out to be solid-state batteries.
Solid state batteries.
As scholars and professors in the industry, they are no strangers.
At this moment, when I suddenly heard that Wang Donglai, a fledgling boy, actually wanted to study solid-state batteries, I was stunned for a moment.
Afterwards, everyone showed different expressions.
Some people looked disdainful, some were noncommittal, and some looked expectant.
As for Academician Chen Quan and Academician Qian Yi, who were sitting at the main seats, their expressions did not change much. Academician Chen Quan said with expectation: "Since Professor Wang has chosen solid-state batteries as his research direction, I I think there must be a reason. I wonder if Professor Wang can explain it?"
Looking around at everyone With an expression on his face, Wang Donglai was unfazed and said: "Of course!" "Solid-state batteries are safe. The solid electrolyte can inhibit lithium dendrites, is not easy to burn, is not easy to explode, has no electrolyte leakage, and will not be exposed to high temperatures. Side reactions will occur, and combustion will not occur due to the production of gas. This is one of them.”
“The second is that the energy density of solid-state batteries is high. It is impossible for liquid electrolyte batteries to have an energy density exceeding 500Wh/kg. However, with all-solid electrolytes, the battery can directly Using metallic lithium as the negative electrode can The amount of negative electrode material is greatly reduced, which significantly improves the energy density of the battery. The energy density that solid-state battery research and development can provide can basically reach 300-400Wh/kg. "Third, the solid-state electrolyte has a long cycle life. Solved the problem of liquid electrolyte charging The problem of the solid electrolyte interface film formed during the discharge process and the lithium dendrite phenomenon have greatly improved the cycleability and service life of lithium batteries. The ideal state can reach about 45,000 times. "
"These three advantages plus. Together, it is undoubtedly the most ideal battery technology "
Just when Wang Dong finished speaking and Academician Chen Quan and Academician Qian Yi who were in charge did not comment, Professor Lei from Peking University suddenly chuckled and said: "Professor Wang, I have. Two questions, I wonder if Professor Wang can answer them?”
Wang Donglai looked at Professor Lei, nodded and said, "Excuse me."
Professor Lei looked at Wang Donglai carefully, and then slowly said: "Solid-state batteries do have so many benefits, but There are still two problems with solid-state batteries: I don’t know if Professor Wang knows, and if so, what kind of solution is he planning to use?”
“The first is that the interface resistance is too large, and the connection between the solid electrolyte and the electrode material is in a solid state. , so there is a gap between the electrode and the electrolyte The effective contact is weak and the ion transmission kinetics in solid materials is low, which will cause the problem of excessive interface resistance."
When Professor Lei talked about this problem, Wang Donglai said calmly without changing his expression. Sheng said: "Simple, the contact between electrolyte and electrode material By improving the manufacturing process, we can increase the transmission power of ions in solid materials, which is completely possible with current technology.”
Professor Lei was not surprised that Wang Donglai could answer this question, and he was not entangled. Then he asked a second question.
"Secondly, the cost of solid-state batteries is high. As far as I know, based on the current market price of materials, the cost of solid-state batteries is 120-200 knives/kwh. This price is not low. If you want to apply it on a large scale, it will definitely To reduce costs, but reduce It is very difficult to maintain high performance at low cost. I wonder if Professor Wang has any good ideas?”
I have to say that Professor Lei is still somewhat talented, and he can learn it in an instant. I found two problems and started to challenge Wang Donglai.
Although I don’t know why Professor Lei from Peking University would find fault with himself, Wang Donglai doesn’t want to think about it at all.
Again, academic disagreements and arguments are normal.
The two most difficult things in the world are to put other people's money into your own pocket, and to put your own ideas into other people's heads.
Such is the case with academic discussions.
It is doomed that it will not be harmonious, but will be accompanied by arguments and nitpicks.
So, after hearing Professor Lei’s question, Wang Donglai still said calmly: “The problem of high cost is not a big problem in my opinion. Large-scale production and application does not mean that we need to become cabbage. What’s more, once solid-state battery technology achieves a breakthrough, the huge market will even out the costs, which will naturally reduce costs.”
Hearing Wang Donglai’s answer, Professor Lei was convinced. Nothing more was said, but another person stood up and questioned with a sneer on his face: "To put it simply, if it could be so easy to break through, it would have been broken long ago, and it still hasn't broken through until now."
“In my opinion, it is better for Professor Wang to concentrate on the field of mathematics. He has proven himself in the field of mathematics. In the field of new energy, it is different from the field of mathematics.”
Wang Donglai turned his head, looked over, and asked calmly: "Who are you?"
With just such a sentence, the face of this popular man who stood up to speak was ugly.
"Hua Ke University, Gao Qiang."
Professor Gao Qiang suppressed his anger and introduced himself in a cold voice.
“Oh, it turned out to be Professor Gao. I thought someone had snuck in to fish in troubled waters.”
"I don't accept what Professor Gao just said. If a problem is simple, it would have been solved long ago. But this does not mean that others cannot solve it. Problems that have not been solved for so many years are really unsolvable."
"Of course, I think Professor Gao must have never had this experience, so I don't know, this is normal."
Wang Donglai will not suffer in vain.
Although Professor Lei was nitpicking, it was considered an academic discussion, and at most it was just a little emotional.
But this professor Gao Qiang from Hua Science and Technology University is different. He is purely a malicious provocation.
It had nothing to do with him, but he stood up and denied Wang Donglai with white teeth, his tone was secretly sarcastic.
Immediately, he responded to Gao Qiang’s question with a serious face.
These few words were so pungent and mean that Gao Qiang's face turned red with anger.
However, in just a moment, Gao Qiang suppressed the anger in his heart, calmed down, and said loudly: "Since Professor Wang is optimistic about solid-state battery technology, he must have done some research on it, right? Do you know if Professor Wang has researched anything really useful? . ”
“The research and development in the field of batteries is different from the problem proof in the field of mathematics. If you can do mathematics, you can do it, but if you can’t, you can’t. The final result will be very different.”
Gao Qiang's words don't sound problematic, but those present are all people from academia, or people who have contact with academia, so they can naturally understand the meaning of Gao Qiang's words.
Being targeted like this by Gao Qiang, Wang Donglai didn't want to save face for Gao Qiang anymore, so he immediately sneered and said, "It seems that Professor Gao is suspecting me of academic fraud!"
"Tell the truth. , I really don’t like your way of doing things, timid and timid, not enough Atmosphere!”
“Although I don’t understand, I don’t want to understand why you have so much malice towards my research and development of solid-state batteries.”
“This malice makes you so angry. Said, questioning me in front of so many scholars and professors.”
"Logically speaking, I shouldn't talk to you, because it will only make me fall into a self-evident trap."
"However, I am a kind-hearted person, and I don't want to see anyone do stupid things."
"Today, I will let you understand a truth. There is a world outside the sky, and there are people outside the world."
After finishing speaking, Gao Qiang ignored the boiling crowd and the mixed emotions of shock, anger, joy, etc.
Wang Donglai looked at Academicians Chen Quan, Academician Qian Yi and Director Lu who were sitting at the main table, and said loudly: "Academician Chen, Academician Qian, Director Lu, please delay the meeting time, can you find something for me? A big blackboard? ”
"Since Professor Gao doesn't think I can develop solid-state batteries, then I'll let him open his eyes!"
