As soon as Professor Sun Hongbiao finished speaking, many pairs of eyes looked at Lu Zhou.
Especially the representatives and engineers from the companies; their eyes were all shining.
Lu Zhou, who was in the center of attention, was holding a bottle of mineral water with a confused look on his face.
Since when am I so confident?
How come I don't know?
Actually, the reason why he didn't participate in the discussion and was indifferent to the conference wasn't because he already had an idea. It was because he didn't know what to say.
Unlike most of the big names in the materials science field, he had to write a draft before he bragged. Professor Sun suddenly kicked the ball to his feet, and he was caught off guard.
However, Lu Zhou suddenly had an idea. He put down the bottle of mineral water in his hand and adjusted the microphone. He then cleared his throat and spoke.
"… According to what I saw at the MRS Conference, the shuttle effect is the biggest problem for lithium-sulfur batteries. As for how to solve this problem, the academic community hasn't formed a unified conclusion.
"In my personal opinion, I think both ideas are good. Solving it from the positive electrode material is one idea, and using the solid electrolyte as an entry point is also a good idea. We can follow these two lines of thought and advance at the same time. We have to grasp both, and we have to be tough on both. "
When Lu Zhou said this, he couldn't help but praise himself for his wits.
He wasn't sure if the last sentence was appropriate or not. Anyway, he was always on the right track in politics class, so he didn't care too much.
This kind of answer was the least likely to offend people.
The big names were fighting over research funding, but Lu Zhou was paying for his own experiments, so it was better for him to stay out of it.
If he said too much, he would have to take responsibility in the future.
However, Professor Sun Hongbiao obviously didn't plan on letting him go.
The old man smiled and continued to ask.
"Professor Lu is right. However, if we want to concentrate our limited resources to achieve big things, we have to have a focus. From your point of view, which plan do you think is more promising? "
The professor from Shuimu University was also a shrewd person.
He was most likely in the field of cathode surface polymers. He saw that Lu Zhou used a modified PDMS film to solve the lithium dendrites problem, so he bet that Lu Zhou was also optimistic about polymers.
However, to be honest, even though Lu Zhou used the modified PDMS film to solve the lithium dendrite problem, he wasn't optimistic about the shuttle effect of lithium-sulfur batteries. He wasn't optimistic about adding surface polymer materials to the cathode material.
As for the reason, he couldn't explain it. Maybe it was just his intuition.
Thinking of this, Lu Zhou did not know whether to laugh or cry.
Suddenly "learning for free" at the scene, he felt that no matter who he chose, he would offend many people.
After all, he wasn't a nobody in the field of lithium batteries. He was aware that Old Lu valued his opinion. The tickets in his hands could be used as two, or even three.
If he had known it would turn out like this, he would have said that he had something to do and wouldn't have come.
Lu Zhou sighed.
There was no other way.
He didn't want to show off his incomplete research results. However, if he continued to evade, it would be a bit pretentious.
Also, if he was used by people to say that he was "not working hard" on the national project and that he was enjoying the support of the government, it would be bad for his reputation.
He thought for a bit and spoke.
"If I had to say, I'm more optimistic about the hollow carbon sphere."
Many people were stunned by his words.
Especially Professor Sun, he obviously did not expect Lu Zhou's choice.
The professors and scholars in the conference room had different expressions. Some were happy, some were indifferent, and some were dismissive. The company representatives' eyes lit up as they looked forward to Lu Zhou's speech.
As for Old Lu, he had a serious expression on his face.
"Can I ask why?"
"Of course." Lu Zhou paused for a second and said, "The hollow carbon sphere has 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. Also, its structure is stable and has good electrical conductivity. I'm optimistic about it. "
After Lu Zhou finished speaking, Academician Wu from Yan University said, "I have a question."
Lu Zhou made an inviting gesture and said, "Academician Wu, please go ahead."
Academician Wu slowly said, "The hollow carbon sphere is a very new concept, but new concepts often have hidden dangers. Technically speaking, when lithium ions are embedded, it will cause the material to expand. With the charging and discharging cycle, this expansion will cause the alloy to powder. I still have the same opinion, this technology is difficult to apply to industrial production. "
Lu Zhou: "Reducing the particle size of the active material can reduce the degree of micronization. Technically speaking, this is achievable."
Academician Wu's eyes were sharp as he asked, "What about the volume expansion? Have you considered the volume energy density? "
Academician Wu was also an interesting person. He used the tactic of "attacking" the solid-state electrolyte field, but he didn't give people a chance to attack him. He probably wanted to wait until the end of the conference to make the final decision.
However, this was one of the more formal methods.
Science and technology were objective, but whether it was useful or not was subjective.
There weren't many black and white conclusions on technical issues. Ever since the birth of academic conferences, academic exchanges had been carried out through mutual attacks.
If they all said the same thing, then it wouldn't be called a conference, and they wouldn't be able to discuss anything.
Lu Zhou continued to speak, "By dispersing the phase that can be alloyed with lithium metal into the inactive phase that can't be alloyed with lithium metal, in theory, the volume expansion of the active component can be compensated by building a 'buffer framework'."
Academician Wu didn't say anything for a while, but another person stood up.
Professor Wang, who was arguing with Academician Wu about the feasibility of carbon-sulfur composites, asked in a skeptical tone, "How confident are you?"
When Lu Zhou heard this, he wasn't happy.
It's fine if Academician Wu attacks me; after all, we're not in the same direction, but you're in the carbon-sulfur composite field! Everyone's direction is the same, or are you saying that you don't need to worry about the "volume expansion" problem?
Lu Zhou was serious about Professor Wang's question.
"Scientific research isn't infrastructure. Don't expect to succeed just by investing money. You asked me how confident I am. Even if I told you 1% or 99%, what's the use of it other than talking nonsense? "
This sentence made Professor Wang's face turn red, and he was speechless.
Old Man Lu coughed lightly and tried to smooth things over, "Everyone has good intentions. Our discussion should still be focused on academics and harmony."
Professor Sun, who previously encouraged Lu Zhou to speak, noticed that Lu Zhou's answer didn't meet his expectations, so he stood up and spoke again.
"Let me say one more thing."
The old man smiled and said, "Professor Wang is worried, that's why he asked this. Actually, I'm also a bit confused about the hollow carbon spheres. However, I heard that Professor Lu is an expert in the field of computational materials, so you must have your own unique insights. I don't know if it's convenient for you to explain this to us? "
When Professor Sun asked this question, he actually didn't think that Lu Zhou could answer this question from a mathematical point of view. He was just afraid that Lu Zhou would lie to a few professors, but he was afraid that Lu Zhou would also lie to Old Lu.
After all, solving the shuttle effect of lithium-sulfur batteries.
Of course, solving the surface polymer materials that he was researching was the best!
However, he didn't expect that his question was exactly what Lu Zhou wanted.
Lu Zhou smiled awkwardly and looked at Old Lu.
