As soon as Professor Sun Hongbiao finished speaking, a pair of eyes looked towards Lu Zhou.
As soon as these words came out, many people were stunned.
Lu Zhou: “Reducing the particle size of active substances can reduce the degree of micronization, which is technically achievable.”
As for Mr. Lu, he had a serious expression on his face.
At this time, Professor Sun, who had previously encouraged Lu Zhou to speak, seemed to see that Lu Zhou's answer did not meet his expectations, so he began to speak again.
But at this moment, Lu Zhou suddenly had an idea. He put down the mineral water bottle in his hand, straightened the microphone, cleared his throat and said.
However, this can be considered one of the formal methods.
"From my personal point of view, I think both ideas are good. Solving it through cathode materials is one idea, and using solid electrolytes as an entry point is also good. We can go hand in hand with both ideas, and we must grasp it with both hands, and both hands must be strong. "
After Lu Zhou finished speaking, Academician Wu from Yanda University said, "I have a question."
Especially the representatives and engineers from the enterprise, all their eyes were shining.
If you follow the script in a calm manner and a thousand mouths speak the same tone, then it is not called a meeting, and nothing can be discussed at all.
But at this moment, Lu Zhou suddenly had an idea. He put down the mineral water bottle in his hand, straightened the microphone, cleared his throat and said.
Lu Zhou, who was in the center of the line of sight, was holding a mineral water bottle with a question mark on his face.
Suddenly "Baixue" came to the scene, and I always felt that whoever I chose would offend a lot of people.
Lu Zhou, who said this, couldn't help but give himself 32 likes for his wit.
When did I feel confident
Lu Zhou smiled sheepishly, looked at Mr. Lu and asked.
After thinking for a moment, he spoke.
I do not know how
Professor Wang, who was still arguing with Academician Wu about the feasibility of carbon-sulfur composite materials, asked in a skeptical tone: "How sure are you?"
no solution anymore.
Lu Zhou sighed.
There are not so many black-and-white conclusions on technical issues. Since the birth of academic conferences, academic exchanges have been conducted through mutual hostility.
Lu Zhou sighed.
Lu Zhou: “Reducing the particle size of active substances can reduce the degree of micronization, which is technically achievable.”
Professor Sun, in particular, obviously did not expect Lu Zhou's choice.
In fact, the reason why he did not participate in the discussion or even showed indifference to the seminar was not that he already had an idea in mind, but that he did not know what to say.
The professors and scholars in the conference room had different expressions, some were happy, some were noncommittal, and some were dismissive. The representatives from the enterprise had bright eyes, looking forward to Lu Zhou continuing.
Regarding Professor Wang's question, Lu Zhou said seriously and seriously.
Lu Zhou, who was in the center of the line of sight, was holding a mineral water bottle with a question mark on his face.
Thinking of this, Lu Zhou felt dumbfounded.
The professor at Shuimu University is also a good person.
This sentence made Professor Wang choke, his face turned red, and he was speechless.
At this time, Professor Sun, who had previously encouraged Lu Zhou to speak, seemed to see that Lu Zhou's answer did not meet his expectations, so he began to speak again.
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 embedded, it will cause the material to expand in volume, and as the charge and discharge cycles If carried out, this volume expansion will cause the alloy to pulverize. I still believe that this technology is difficult to apply to industrial production."
Unlike most experts in materials science, due to the rigor of a mathematician, 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 moment.
I do not know how
As for the reason, he couldn't explain it, maybe it was just intuition.
The big guys are fighting over the research funds, but since he pays for the experiments himself, it is better not to get involved.
Most likely, I was working on surface polymers for cathode materials. Seeing that he solved the lithium dendrite problem with a modified PDMS membrane, I bet that he was probably as optimistic about the direction of polymers as I was, and then he decisively pushed him out and used him as a gun.

I still believe that this technology is difficult to apply to industrial production."
It’s okay for Academician Wu to criticize me. After all, it’s not the same direction. You, who is engaged in carbon-sulfur composite materials, are criticizing me for making wool! Everyone is going in the same direction, or do you think you don’t have to consider the issue of “volume expansion” if you criticize me
But at this moment, Lu Zhou suddenly had an idea. He put down the mineral water bottle in his hand, straightened the microphone, cleared his throat and said.
This kind of snake oil answer is the least likely to offend people.
"Let me say one more thing."
Lu Zhou, who said this, couldn't help but give himself 32 likes for his wit.
The old man smiled warmly and said, "Professor Wang also asked this out of worry. In fact, 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 computational materials, so he must be If you have unique insights, would it be convenient for you to explain the mystery to us?"
There are not so many black-and-white conclusions on technical issues. Since the birth of academic conferences, academic exchanges have been conducted through mutual hostility.
Lu Zhou, who said this, couldn't help but give himself 32 likes for his wit.
Science and technology are objective, but whether they are useful or not is subjective.
"... 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 reached a unified conclusion on how to solve this problem."
Regarding Professor Wang's question, Lu Zhou said seriously and seriously.
As soon as Professor Sun Hongbiao finished speaking, a pair of eyes looked towards Lu Zhou.
"From my personal point of view, I think both ideas are good. Solving it through cathode materials is one idea, and using solid electrolytes as an entry point is also good. We can go hand in hand with both ideas, and we must grasp it with both hands, and both hands must be strong. "

In fact, the reason why he did not participate in the discussion or even showed indifference to the seminar was not that he already had an idea in mind, but that he did not know what to say.
Academician Wu was speechless for the time being, but another person stood up again.
Lu Zhou, who said this, couldn't help but give himself 32 likes for his wit.
But to be honest, although Lu Zhou used modified PDMS films to solve the lithium dendrite problem, he is not optimistic about using the same method of adding surface polymer materials to the cathode material due to the shuttle effect unique to lithium-sulfur batteries.
Science and technology are objective, but whether they are useful or not is subjective.
After Lu Zhou finished speaking, Academician Wu from Yanda University said, "I have a question."

After thinking for a moment, he spoke.
As for whether the last sentence was appropriate to use here, he didn't know. Anyway, his politics class had always been close to the passing line, and he didn't bother to care so much.
Academician Wu said unhurriedly: "Hollow carbon spheres are a very new concept, but new concepts often have hidden dangers.

Lu Zhou made a gesture of invitation: "Academician Wu, please speak."
"Can you please tell me the reason?"
This kind of snake oil answer is the least likely to offend people.
After Lu Zhou finished speaking, Academician Wu from Yanda University said, "I have a question."
But at this moment, Lu Zhou suddenly had an idea. He put down the mineral water bottle in his hand, straightened the microphone, cleared his throat and said.
When Professor Sun asked this question, he actually didn't think he could really answer the question from a mathematical point of view. He was just afraid that this guy would talk nonsense at the meeting and fool a few professors, which was fine. I was deceived.
The big guys are fighting over the research funds, but since he pays for the experiments himself, it is better not to get involved.
As soon as Professor Sun Hongbiao finished speaking, a pair of eyes looked towards Lu Zhou.
Lu Zhou, who said this, couldn't help but give himself 32 likes for his wit.
Academician Wu's eyes were sharp and he continued to ask: "What about volume expansion? Have you considered volumetric energy density?"
Upon hearing this, Lu Zhou suddenly became unhappy.
It’s okay for Academician Wu to criticize me. After all, it’s not the same direction. You, who is engaged in carbon-sulfur composite materials, are criticizing me for making wool! Everyone is going in the same direction, or do you think you don’t have to consider the issue of “volume expansion” if you criticize me
"Of course," Lu Zhou paused for a moment, then continued, "Hollow carbon spheres have a large internal cavity and are 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 structural stability and good conductivity make me personally very optimistic about it.”
Upon hearing this, Lu Zhou suddenly became unhappy.
But to be honest, although Lu Zhou used modified PDMS films to solve the lithium dendrite problem, he is not optimistic about using the same method of adding surface polymer materials to the cathode material due to the shuttle effect unique to lithium-sulfur batteries.
I said too much, but I will be responsible in the future.
This kind of snake oil answer is the least likely to offend people.
Lu Zhou sighed.
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 embedded, it will cause the material to expand in volume, and as the charge and discharge cycles If carried out, this volume expansion will cause the alloy to pulverize. I still believe that this technology is difficult to apply to industrial production."
However, Professor Sun Hongbiao obviously did not intend to let his big tree go.
When did I feel confident
"If I have to say, I personally am more optimistic about the direction of hollow carbon balls."
The old gentleman smiled and continued to ask.
Regarding Academician Wu's question, Lu Zhou continued: "By dispersing the phase that can alloy with lithium metal into the inactive phase that does not alloy with lithium metal, the volume expansion problem of the active ingredient can theoretically be solved by building The 'buffer skeleton' compensates."
When did I feel confident
Suddenly "Baixue" came to the scene, and I always felt that whoever I chose would offend a lot of people.

The professor at Shuimu University is also a good person.
"Professor Lu is right, but if we want to concentrate our limited resources to achieve great things, we must have a focus. From your point of view, which plan do you think is more promising?"
Upon hearing this, Lu Zhou suddenly became unhappy.

Lu Zhou smiled sheepishly, looked at Mr. Lu and asked.
In fact, the reason why he did not participate in the discussion or even showed indifference to the seminar was not that he already had an idea in mind, but that he did not know what to say.
With a rigorous attitude, he didn't want to show off his unfinished research results, but if he continued to shirk it, it would be a bit pretentious.
After thinking for a moment, he spoke.

If he had known it would turn out like this, he would have just excused himself from coming because something happened.
After all, he is not a little transparent when it comes to lithium batteries, and he is also conscious of Mr. Lu's emphasis on his opinions. The tickets he holds in his hand may be used as two or even three.

As for the reason, he couldn't explain it, maybe it was just intuition.
If he had known it would turn out like this, he would have just excused himself from coming because something happened.
Science and technology are objective, but whether they are useful or not is subjective.
But to be honest, although Lu Zhou used modified PDMS films to solve the lithium dendrite problem, he is not optimistic about using the same method of adding surface polymer materials to the cathode material due to the shuttle effect unique to lithium-sulfur batteries.
After thinking for a moment, he spoke.
Most likely, I was working on surface polymers for cathode materials. Seeing that he solved the lithium dendrite problem with a modified PDMS membrane, I bet that he was probably as optimistic about the direction of polymers as I was, and then he decisively pushed him out and used him as a gun.

There are not so many black-and-white conclusions on technical issues. Since the birth of academic conferences, academic exchanges have been conducted through mutual hostility.
When did I feel confident
Lu Zhou, who was in the center of the line of sight, was holding a mineral water bottle with a question mark on his face.
"Scientific research is not about infrastructure construction. Don't expect that it will be successful just by throwing money into it. If you ask me how sure I am, even if I tell you 1% or 99%, what's the use except talking nonsense?"
If you follow the script in a calm manner and a thousand mouths speak the same tone, then it is not called a meeting, and nothing can be discussed at all.
As soon as these words came out, many people were stunned.
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 embedded, it will cause the material to expand in volume, and as the charge and discharge cycles If carried out, this volume expansion will cause the alloy to pulverize. I still believe that this technology is difficult to apply to industrial production."
With a rigorous attitude, he didn't want to show off his unfinished research results, but if he continued to shirk it, it would be a bit pretentious.
As for whether the last sentence was appropriate to use here, he didn't know. Anyway, his politics class had always been close to the passing line, and he didn't bother to care so much.
Especially the representatives and engineers from the enterprise, all their eyes were shining.
Lu Zhou sighed.
Regarding Academician Wu's question, Lu Zhou continued: "By dispersing the phase that can alloy with lithium metal into the inactive phase that does not alloy with lithium metal, the volume expansion problem of the active ingredient can theoretically be solved by building The 'buffer skeleton' compensates."
As soon as Professor Sun Hongbiao finished speaking, a pair of eyes looked towards Lu Zhou.
But at this moment, Lu Zhou suddenly had an idea. He put down the mineral water bottle in his hand, straightened the microphone, cleared his throat and said.
Lu Zhou smiled sheepishly, looked at Mr. Lu and asked.
I do not know how
I do not know how
When Professor Sun asked this question, he actually didn't think he could really answer the question from a mathematical point of view. He was just afraid that this guy would talk nonsense at the meeting and fool a few professors, which was fine. I was deceived.
When did I feel confident
Academician Wu was speechless for the time being, but another person stood up again.
The old man smiled warmly and said, "Professor Wang also asked this out of worry. In fact, 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 computational materials, so he must be If you have unique insights, would it be convenient for you to explain the mystery to us?"
The professor at Shuimu University is also a good person.
After thinking for a moment, he spoke.
Lu Zhou, who was in the center of the line of sight, was holding a mineral water bottle with a question mark on his face.
At this time, Professor Sun, who had previously encouraged Lu Zhou to speak, seemed to see that Lu Zhou's answer did not meet his expectations, so he began to speak again.
Thinking of this, Lu Zhou felt dumbfounded.
Most likely, I was working on surface polymers for cathode materials. Seeing that he solved the lithium dendrite problem with a modified PDMS membrane, I bet that he was probably as optimistic about the direction of polymers as I was, and then he decisively pushed him out and used him as a gun.
Lu Zhou made a gesture of invitation: "Academician Wu, please speak."
Professor Wang, who was still arguing with Academician Wu about the feasibility of carbon-sulfur composite materials, asked in a skeptical tone: "How sure are you?"
The old gentleman smiled and continued to ask.
Especially the representatives and engineers from the enterprise, all their eyes were shining.
Of course it is the surface polymer material I am studying!
Suddenly "Baixue" came to the scene, and I always felt that whoever I chose would offend a lot of people.
But at this moment, Lu Zhou suddenly had an idea. He put down the mineral water bottle in his hand, straightened the microphone, cleared his throat and said.
The big guys are fighting over the research funds, but since he pays for the experiments himself, it is better not to get involved.
Upon hearing this, Lu Zhou suddenly became unhappy.
However, Professor Sun Hongbiao obviously did not intend to let his big tree go.

"Let me say one more thing."
It’s okay for Academician Wu to criticize me. After all, it’s not the same direction. You, who is engaged in carbon-sulfur composite materials, are criticizing me for making wool! Everyone is going in the same direction, or do you think you don’t have to consider the issue of “volume expansion” if you criticize me
As soon as these words came out, many people were stunned.

Regarding Professor Wang's question, Lu Zhou said seriously and seriously.

no solution anymore.
This sentence made Professor Wang choke, his face turned red, and he was speechless.

Especially the representatives and engineers from the enterprise, all their eyes were shining.
Academician Wu is also an interesting person. He adopts "defeat" tactics for directions other than the direction of solid electrolytes, but avoids talking about his own views and does not give people the opportunity to counterattack. He probably planned to wait until the end of the seminar to make a final decision.
"Professor Lu is right, but if we want to concentrate our limited resources to achieve great things, we must have a focus. From your point of view, which plan do you think is more promising?"
"Scientific research is not about infrastructure construction. Don't expect that it will be successful just by throwing money into it. If you ask me how sure I am, even if I tell you 1% or 99%, what's the use except talking nonsense?"

Lu Zhou smiled sheepishly, looked at Mr. Lu and asked.
"Of course," Lu Zhou paused for a moment, then continued, "Hollow carbon spheres have a large internal cavity and are 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 structural stability and good conductivity make me personally very optimistic about it.”
After all, solving the shuttle effect of lithium-sulfur batteries.
Regarding Professor Wang's question, Lu Zhou said seriously and seriously.
"... 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 reached a unified conclusion on how to solve this problem."
This sentence made Professor Wang choke, his face turned red, and he was speechless.
This kind of snake oil answer is the least likely to offend people.
However, this can be considered one of the formal methods.
"Can you please tell me the reason?"

As soon as Professor Sun Hongbiao finished speaking, a pair of eyes looked towards Lu Zhou.
Upon hearing this, Lu Zhou suddenly became unhappy.
Mr. Lu coughed lightly and smoothed things over by saying, "Everyone's original intentions are good. Our discussion should focus on academics and harmony."
"If I have to say, I personally am more optimistic about the direction of hollow carbon balls."
However, this can be considered one of the formal methods.
However, Professor Sun Hongbiao obviously did not intend to let his big tree go.
As for whether the last sentence was appropriate to use here, he didn't know. Anyway, his politics class had always been close to the passing line, and he didn't bother to care so much.
When did I feel confident
"From my personal point of view, I think both ideas are good. Solving it through cathode materials is one idea, and using solid electrolytes as an entry point is also good. We can go hand in hand with both ideas, and we must grasp it with both hands, and both hands must be strong. "

If you follow the script in a calm manner and a thousand mouths speak the same tone, then it is not called a meeting, and nothing can be discussed at all.

Lu Zhou smiled sheepishly, looked at Mr. Lu and asked.
The professors and scholars in the conference room had different expressions, some were happy, some were noncommittal, and some were dismissive. The representatives from the enterprise had bright eyes, looking forward to Lu Zhou continuing.
There are not so many black-and-white conclusions on technical issues. Since the birth of academic conferences, academic exchanges have been conducted through mutual hostility.
Lu Zhou sighed.
If you follow the script in a calm manner and a thousand mouths speak the same tone, then it is not called a meeting, and nothing can be discussed at all.
"This is easy to talk about. Is there a blackboard?"
Professor Sun, in particular, obviously did not expect Lu Zhou's choice.
"Can you please tell me the reason?"
