Scholar’s Advanced Technological System

As soon as Professor Sun Hongbiao's voice dropped, a pair of eyes looked at the landing boat.

Especially the representatives and engineers from the enterprise side, all eyes are shining.

At the moment, Lu Zhou, who was at the center of the line of sight, was holding a mineral water bottle with a question mark on his face.

When can I be confident?

I do not know how?

In fact, the reason why he did not participate in the discussion and even showed indifference to the seminar performance was not that he already had an idea in his heart, but that he did not know what to say.

Unlike most Daniels in materials science, due to the rigor of a mathematician, he still had to write a draft before bragging. Professor Sun suddenly kicked the ball to his feet, which caught him off guard for a while.

But at this moment, Lu Zhou suddenly had an idea, put down the mineral water bottle in his hand, straightened the microphone, and cleared his throat.

"... According to what I heard at the mrs conference, for the lithium-sulfur battery, the shuttle effect is the biggest problem that constrains this technology. And how to solve this problem, the academic community has not formed a unified conclusion."

"My personal point of view, I think both ideas are good. Solving from the cathode material is an idea. It is also good to use solid electrolyte as the starting point. We can go hand in hand with both ideas, both hands must be grasped, both hands must be hard. "

Lu Zhou, who said this, couldn't help but give his wit 32 praises.

As to whether the last sentence is suitable for use here, he is not sure, anyway, his political class has been walking near the passing line, and he is too lazy to care so much.

This kind of answer is the least likely to offend people.

The big guys are tearing up Zheng Huan for research funding, but he pays for the experiment by himself, and it is better not to mix in blindly.

Too much talk, but in the future it will be responsible.

However, Professor Sun Hongbiao obviously did not intend to let go of his big tree like this.

I saw the old man smiled and continued to ask.

"Professor Lu is right, but it is true to say so, but we have to focus on limited resources to achieve a great cause. There must always be a point. From your point of view, which one do you think is more promising?"

The professor at Mizuki University is also personal.

Mostly he was doing the polymer on the surface of the positive electrode material. Seeing that he used the modified pdms film to solve the lithium dendrite problem, he bet he was mostly optimistic about the polymer direction like himself, and then pushed him decisively.

But to be honest, although Lu Zhou used the modified pdms film to solve the lithium dendrite problem, he was not optimistic about the method of adding surface polymer materials to the cathode material for the shuttle effect peculiar to lithium sulfur batteries.

As for the reason, he couldn't tell why, maybe it was just intuition.

Thinking of this, Lu Zhou not only cried and laughed.

Suddenly, at the "Bai Xue" scene, I always felt that whoever I chose would offend many people.

After all, he is not a little transparent in the lithium battery. He also consciously values ​​Lu Lao's attention to his opinions. I am afraid that the ticket I hold in my hand can be used as two or even three.

Knowing that this would happen, he reasoned that something would not come.

Lu Zhou sighed.

no solution anymore.

In a rigorous attitude, he didn't want to show the results of the research that had not been perfected, but he continued to evade it, which was a bit arrogant.

And if it is used by a person with intentions, saying that he "does not work hard" on the national project, and enjoys the support of the policy, but then fishes in the muddy waters, the influence is not good.

After thinking for a moment, he said.

"If I have to say anything, I personally prefer the direction of the hollow carbon sphere."

As soon as this word came out, many people stopped.

Especially Professor Sun, obviously did not expect Lu Zhou's choice.

The professors and scholars in the conference room have different expressions, some of them are happy, some of them are dismissive, and some of them are dismissive. The representatives from the company's side had bright eyes, looking forward to the landing boat to continue.

As for Lu Lao, it was an expression that attached importance to his face.

"Can I ask why?"

"Of course," Lu Zhou paused for a moment and continued. "Hollow carbon spheres have large internal cavities and are suitable as carbon substrates with high negative sulfur content. At the same time, the outer porous shell structure can effectively suppress the diffusion of polysulfide ions "In addition, because of its structural stability and good electrical conductivity, I personally like it."

After Lu Zhou's words fell, Academician Wu from Yanda said, "I have a question."

Lu Zhou made a gesture of "Please, Academician Wu, please."

Academician Wu said eagerly: "Hollow carbon spheres are a very new concept, but new concepts often have hidden dangers. Technically speaking, when lithium ions are embedded, the material will expand in volume, and with charge and discharge cycles Go ahead, this volume expansion will lead to powdering of the alloy. I still think that this technology is difficult to apply to industrial production. "

Lu Zhou: "Reducing the particle size of the active substance can reduce the degree of micronization, which is technically achievable."

Academician Wu looked sharp and continued to ask, "What about volume expansion? Have you considered volume energy density?"

This academician Wu is also an interesting person. He adopted a tadpole tactic in directions other than the direction of solid electrolyte, but avoided talking about his own point of view, and did not give people a chance to yell at him. Probably intend to wait until the end of the seminar to come to a final word.

However, this can be regarded as one of the formal means.

Science and technology are objective, but they are subjective to use.

Technically, there are not so many non-black and white conclusions. Since the birth of academic conferences, academic exchanges have been carried out in mutual dialogue.

According to this propaganda section in a gentle manner, a thousand mouths are an argument, so it is not a meeting, and nothing can be discussed at all.

Regarding Academician Wu's question, Lu Zhou continued: "Through a phase that can be alloyed with lithium metal, dispersed into an inactive phase that is not alloyed with lithium metal, the volume expansion of the active ingredient can theoretically be solved by building 'Buffer skeleton'. "

Academician Wu has nothing to say for a while, but another person stands up again.

I saw Professor Wang who was still arguing with the academician Wu about the feasibility of carbon-sulfur composites, and asked in a skeptical tone: "How confident are you?"

Upon hearing this ~ www.readwn.com ~ Lu Zhou was unhappy.

Academician Wu: I do n’t care. After all, it ’s not the same direction. If you are engaged in carbon and sulfur composites, I ’ll do wool! Everyone's direction is the same, or do you not have to think about the "volume expansion" problem if you talk to me?

For Professor Wang's questions, Lu Zhou was serious and serious.

"Scientific research is not about infrastructure. Don't expect money to be thrown in and it will be successful. You ask me how confident I am, even if I tell you 1% or 99%, what's the use of it other than to open the mouth?"

This sentence blushed Professor Wang's face to speech, speechless.

Lao Lu coughed softly and rounded the field: "Everyone's original intentions are good. Our discussion is mainly academic, and harmony is the most important thing."

At this time, Professor Sun, who had previously urged Lu Zhou to speak, seemed to see that Lu Zhou's answer did not meet his expectations, and then he got up and spoke again.

"Let me say it again."

I saw the old gentleman smiled kindly and said, "Professor Wang also asked this question out of worry. In fact, I am a bit confused about the direction of hollow carbon spheres. But I heard that Professor Lu is an expert in the field of computational materials. I have unique insights. I do n’t know if it is convenient to answer the mystery of it? ”

When Professor Sun asked this sentence, he didn't actually think that he could really answer this question from a mathematical point of view, but he was afraid that the boy would open his mouth at the meeting, and it was fine for a few professors to flicker. Old also gives Huyou.

After all, solve the shuttle effect of lithium-sulfur batteries.

That is naturally the surface polymer material that I am studying!

What he didn't expect, however, was that his questioning was right in the heart of Lu Zhou.

I saw Lu Zhou smiled embarrassedly, looked at Lu Lao and asked.

"This is easy to say, is there a blackboard?"
