Chapter 304 Hollow Carbon Ball Is Good

As soon as Professor Sun Hongbiao's words fell, a pair of eyes turned towards Lu Zhou.

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

And Lu Zhou, who was in the center of sight, was holding a mineral water bottle at the moment, with question marks on his face.

When did I have a plan?

I do not know how?

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

Unlike most big names in materials science, due to the rigor of mathematicians, he still has to make 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, cleared his throat and said.

"...According to what I saw at the MRS conference, for lithium-sulfur batteries, the shuttle effect is the biggest problem restricting this technology. However, the academic community has not formed a unified conclusion on how to solve this problem."

"My personal point of view is that both ideas are good. It is a way to solve the problem from the positive electrode material, and it is also good to use the solid electrolyte as an entry point. We can go hand in hand along the two ideas, grasping with both hands, and both hands must be hard. "

Lu Zhou, who said this sentence, couldn't help giving himself 32 likes for his wit.

As for whether the last sentence is appropriate to use here, he doesn't know. Anyway, his politics class has always been near the passing line, so he doesn't bother to care so much.

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

The bosses are torn apart for research funding, but he pays for the experiment himself, so it's better not to go in and mix it up.

If you talk too much, you will be responsible in the future.

However, Professor Sun Hongbiao obviously doesn't intend to let his big tree go.

The old man smiled and continued to ask.

"Professor Lu is right, but what he said is true, but if we want to concentrate limited resources to achieve a great cause, there must be a focus. From your point of view, which solution do you think is more promising?"

This professor at Mizuki University is also a fine individual.

Most of them are the surface polymers of positive electrode materials. Seeing that he solved the lithium dendrite problem with modified PDMS membranes, he bet that he is probably as optimistic about the direction of polymers as himself, and then decisively pushed him out as a gun.

But to be honest, although Lu Zhou solved the lithium dendrite problem with a modified PDMS film, he is not optimistic about the method of adding surface polymer materials to the positive electrode material for the unique shuttle effect of lithium-sulfur batteries.

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

Thinking of this, Lu Zhou was not only dumbfounded.

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 when it comes to lithium batteries, so he is also conscious of the importance Lu Lao attaches to his opinions. The tickets I hold in my hand, I am afraid that one ticket can be used as two tickets, or even three tickets.

If he had known it would turn out like this, he would have said that something had happened and he would not come.

Lu Zhou sighed.

no solution anymore.

With a rigorous attitude, he didn't want to show off his unfinished research results, but if he continued to evade, it would be a bit hypocritical.

And if it is used by someone with a heart, saying that he "doesn't work hard" on national projects, and enjoys the support of the policy but fishes in troubled waters, the influence of spreading it is always bad.

After thinking for a moment, he spoke.

"If I have to say it, I personally prefer the direction of hollow carbon spheres."

As soon as these words came out, many people were stunned.

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

The professors and scholars in the conference room had different expressions, some were happy, some were noncommittal, and some were dismissive. The representatives of the enterprise had bright eyes, expecting Lu Zhou to continue.

As for Mr. Lu, he had a serious expression on his face.

"Can I ask why?"

"Of course." Lu Zhou paused for a moment, then continued, "Hollow carbon spheres have a large internal cavity, which is suitable as a carbon matrix with high negative sulfur content. At the same time, the external porous shell structure can effectively inhibit the diffusion of polysulfide ions. .In addition, its own structural stability and good electrical conductivity, I am very optimistic about it.”

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

Lu Zhou made a gesture of invitation: "Academician Wu, please speak."

Academician Wu said unhurriedly: "Hollow carbon spheres are a very new concept, but new concepts often have hidden dangers. Technically speaking, when lithium ions are intercalated, the volume of the material will expand, and as the charge and discharge cycles Proceeding, this volume expansion will lead to alloy powdering. I still have the opinion 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's eyes were sharp, and he continued to ask: "What about the volume expansion? Have you considered the volumetric energy density?"

This academician Wu is also an interesting person. He adopts the tactics of "striking" in directions other than the direction of solid electrolytes, but avoids talking about his own views and does not give people the opportunity to fight back. Probably intending to wait until the end of the seminar to make a final decision.

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

Science and technology are objective, but whether they are useful or not is subjective.

For technical issues, there are not so many black and white conclusions. Since the birth of academic conferences, academic exchanges have been carried out in mutual conflicts.

If you follow the scriptures in a friendly manner, and a thousand mouths are all the same, then it is not called a meeting, and nothing can be discussed at all.

Regarding Academician Wu's question, Lu Zhou continued: "Through the phase that can alloy with lithium metal, disperse into the inactive phase that does not alloy with lithium metal, in theory, the volume expansion of the active component can be solved by building 'buffer skeleton' to compensate."

Academician Wu was speechless for a while, but another person stepped forward again.

I saw Professor Wang, who was still arguing with Academician Wu about the feasibility of carbon-sulfur composite materials, asked in a suspicious tone: "How sure are you?"

Hearing this, Lu Zhou was immediately unhappy.

It's fine if Academician Wu hates me, after all, it's not the same direction, you who are engaged in carbon-sulfur composite materials hate me for wool! Everyone's direction is similar, or you don't have to think about "volume expansion" if you hate me?

Regarding Professor Wang's question, Lu Zhou was serious and serious.

"Scientific research is not about infrastructure construction. Don't expect success if you throw money in it. You ask me how sure I am, and even if I tell you 1% or 99%, what's the use of it except talking about it?"

This sentence made Professor Wang's face flushed red, and he was speechless.

Mr. Lu coughed lightly, smoothed things over and said, "Everyone's original intentions are good, and our discussion will still focus on academics and harmony."

At this time, Professor Sun, who had encouraged Lu Zhou to speak before, seemed to see that Lu Zhou's answer did not meet his expectations, so he stood up to speak again.

"Let me say one more thing."

The old gentleman smiled warmly and said: "Professor Wang asked this question out of worry. Actually, I am also a little confused about the direction of hollow carbon spheres. But I heard that Professor Lu is an expert in the field of computing materials, so it must be I don’t know if it’s convenient for you to have a unique insight, explain the mystery for us?”

When Professor Sun asked this question, he didn't really think that he could really answer the question from a mathematical point of view, but he was just afraid that this kid would talk nonsense at the meeting, and it would be fine to fool a few professors. The old man was also fooled.

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

That's naturally the surface polymer material I'm researching!

However, what he didn't expect was that his question hit Lu Zhou's hands.

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

"That's easy to say, is there a blackboard?"
