Unfortunately, Chen Yushan guessed wrong this time.
It is about the lithium-air battery project initiated two or three years ago.
Lu Zhou thought for a moment and said, "Have you done any simulation? Let me take a look."
"We have been stuck on this bottleneck for half a year," Yang Xu shook his head, "We have tried every possible method..."
Watching Yang Xu simulate the demonstration on the software, a solemn expression appeared on Lu Zhou's face.
After returning to Jinling, Lu Zhou had indeed made plans to start a new round of retreat, and had indeed made up his mind to "never step out of the house until the Riemann Hypothesis was solved." However, in reality, things were really different. Too much.
Taking a deep breath, Yang Xu continued: "Based on experimental analysis, we found that under a certain pressure difference, the gas on the high-pressure side of this type of porous silicon material can slowly transport molecules of a specific diameter to the low-pressure side. Our The project team immediately followed up on this research and successfully produced an exchange membrane capable of screening gas molecules in the 3.4-3.5A diameter range."
"...I'll go back and think about it. If there is any new progress, I will tell you."
Unfortunately, Chen Yushan guessed wrong this time.
The diameter of the oxygen molecule is exactly 3.46A, which is exactly within this range. Although the Ar gas molecule is 3.4, it is also close to this screening interval, but Ar is a rare gas, so it has no impact.
Yang Xu: "Do you still remember the porous silicon-based molecular exchange membrane I mentioned in my research progress report some time ago?"
He asked Wang Peng to drive him to the Jinling Institute for Advanced Study. As soon as Lu Zhou stepped into the laboratory, he was grabbed by the arm by Yang Xu, who looked in pain.
The person who called him for help this time was Yang Xu, director of the Institute of Computational Materials.
How come this year, the entire research has taken a turn for the worse
After returning to Jinling, Lu Zhou had indeed made plans to start a new round of retreat, and had indeed made up his mind to "never step out of the house until the Riemann Hypothesis was solved." However, in reality, things were really different. Too much.
"It's not good at all." The expression on Yang Xu's face was a little bitter, and he shook his head and continued, "The upper and lower boundaries of the screening interval are not a fixed value, but change linearly with the air pressure... You understand."
On the screen, the red dots and green dots distributed on the right side of the molecular exchange membrane began to gather towards the surface of the molecular exchange membrane, as if they had found an outlet for pouring.
As for the content of the request for help...

"I can think of ways to deal with a series of impurities including water molecules, carbon dioxide, and even carbon monoxide. There are also gases with weak contents such as sulfur dioxide that can be easily dealt with, but only nitrogen... is really difficult to deal with. , It’s like a swarm of flies that can’t be driven away.”
It is about the lithium-air battery project initiated two or three years ago.
"We have been stuck on this bottleneck for half a year," Yang Xu shook his head, "We have tried every possible method..."
IBM didn't believe in this evil at first, and roped in the famous Almaden Research Center to work on this project together. It even used distributed computing technology, which seems to have some black technology elements now, to locate each particle entering the reaction system. of oxygen atoms and precisely distribute them to the lithium anode...
"Don't be like this. If you have something to say, aren't I here? Don't make it sound like your last words. If you have any questions, tell me. I'll see if I can help you think of a solution... "
Speaking of which, Lu Zhou was quite surprised. Until the end of last year, he had been able to see news about significant progress in lithium-air battery research from reports from the Institute of Computational Materials.
Even though nitrogen can usually be used as a protective gas, such as in the food industry, it is not suitable for lithium-air batteries because nitrogen will react with lithium to form unstable Li3N.
If even a tiny bit of impurity comes in, what they make is not a battery, but a bomb.
How come this year, the entire research has taken a turn for the worse
Yang Xu: "Do you still remember the porous silicon-based molecular exchange membrane I mentioned in my research progress report some time ago?"
Before finding Lu Zhou, the research team on the lithium-air battery project led by Yang Xu had been stuck on this bottleneck for almost half a year, and so far there has been no progress at all.
Yang Xu explained while pointing at the image on the screen.
As for the content of the request for help...
He asked Wang Peng to drive him to the Jinling Institute for Advanced Study. As soon as Lu Zhou stepped into the laboratory, he was grabbed by the arm by Yang Xu, who looked in pain.
If this thing can be researched, it will be a market worth tens of thousands or trillions!
On the screen, the red dots and green dots distributed on the right side of the molecular exchange membrane began to gather towards the surface of the molecular exchange membrane, as if they had found an outlet for pouring.
Yang Xu explained while pointing at the image on the screen.
Not to mention the technical cost of controlling the air pressure difference to such an accurate level, from a safety perspective, it is absolutely impossible for them to allow the redox reaction system in the lithium-air battery to run on such an unstable steel wire. .
"I can think of ways to deal with a series of impurities including water molecules, carbon dioxide, and even carbon monoxide. There are also gases with weak contents such as sulfur dioxide that can be easily dealt with, but only nitrogen... is really difficult to deal with. , It’s like a swarm of flies that can’t be driven away.”

Although the silicon material from the Institute of Computational Materials has indeed brought a lot of hope to research in this direction, if the problem of eliminating the passage of other impurity gases cannot be solved, this can only be regarded as an interesting interim result. , no more advanced than those ideas of putting an oxygen tank outside the battery.
Lu Zhou thought about it carefully, recalled some of the contents of the report, nodded and said.
It’s not surprising that research in cutting-edge fields like this will encounter problems that cannot be solved, but the problem that tortured this guy to this point...
Seeing Yang Xu's explosive state of mind really shocked Lu Zhou.
It is about the lithium-air battery project initiated two or three years ago.
Even though nitrogen can usually be used as a protective gas, such as in the food industry, it is not suitable for lithium-air batteries because nitrogen will react with lithium to form unstable Li3N.
"follow me."
Since this guy became the director of the Institute of Computational Materials, he has led many large projects, and he has also solved many problems in materials science for Jinling Institute of Advanced Studies.
Even IBM, which was rich and powerful, finally had to believe this evil, cut off this bottomless pit-like project entirely, and fired the project leader.
The key reason why lithium-air batteries are difficult to develop is that lithium metal is too reactive. And the impurities that need to be eliminated are too lazy.
Taking Lu Zhou to the computer, Yang Xu held the mouse and clicked twice. Soon, a three-dimensional composition of a silicon-based molecular exchange membrane with a porous network superposition structure appeared in front of Lu Zhou.

As for whether the air pressure on both sides can be maintained at a constant value to ensure that only oxygen passes through the exchange membrane...
How come this year, the entire research has taken a turn for the worse
If it really doesn't work, he can only declare that this technical route has failed and think about other possible directions.
"Some impression."

On the screen, the red dot marking nitrogen has penetrated the exchange membrane and contacted the lithium negative electrode.

In short, this porous silicon-based molecular exchange membrane is like an elastic fishing net. The larger it is, the larger the mesh of the fishing net will be, and the more fish will slip through the net...
Hearing Yang Xu's "thank you", Lu Zhou didn't notice the despair deep in the heart of this "academic leader who had begun to doubt his life". Instead, he smiled sheepishly.

Yang Xu has made it very clear that the movement of the upper and lower boundaries of the entire screening interval changes linearly with the change of the air pressure difference on both sides.

However, when the surface pressure continues to increase as the pressure difference increases, it reaches position B. , nitrogen will also begin to pass through the exchange membrane..."
Speaking of which, Lu Zhou was quite surprised. Until the end of last year, he had been able to see news about significant progress in lithium-air battery research from reports from the Institute of Computational Materials.
Seeing that Lu Zhou couldn't think of a good solution, Yang Xu gradually began to sigh without any hope.
"Don't be like this. If you have something to say, aren't I here? Don't make it sound like your last words. If you have any questions, tell me. I'll see if I can help you think of a solution... "
If nitrogen is allowed to enter the circulation system of the lithium-air battery, the entire battery may be useless after only a few runs.
IBM didn't believe in this evil at first, and roped in the famous Almaden Research Center to work on this project together. It even used distributed computing technology, which seems to have some black technology elements now, to locate each particle entering the reaction system. of oxygen atoms and precisely distribute them to the lithium anode...
As he spoke, Yang Xu held the mouse with his right hand and tapped it twice with his index finger.
"...I thank you!"
As he spoke, Yang Xu held the mouse with his right hand and tapped it twice with his index finger.
As for the final result, it is also obvious.
Yang Xu has made it very clear that the movement of the upper and lower boundaries of the entire screening interval changes linearly with the change of the air pressure difference on both sides.
Seeing Yang Xu's explosive state of mind really shocked Lu Zhou.
His intuition told him that if even he couldn't do it, who in the entire Institute for Advanced Study would have hope of solving this problem, probably only Professor Lu, one of the founders of computational materials science.
It’s not surprising that research in cutting-edge fields like this will encounter problems that cannot be solved, but the problem that tortured this guy to this point...
If even a tiny bit of impurity comes in, what they make is not a battery, but a bomb.
Before finding Lu Zhou, the research team on the lithium-air battery project led by Yang Xu had been stuck on this bottleneck for almost half a year, and so far there has been no progress at all.
Speaking of which, Lu Zhou was quite surprised. Until the end of last year, he had been able to see news about significant progress in lithium-air battery research from reports from the Institute of Computational Materials.
Even IBM, which was rich and powerful, finally had to believe this evil, cut off this bottomless pit-like project entirely, and fired the project leader.
"What's there to thank me for..."
"It's not good at all." The expression on Yang Xu's face was a little bitter, and he shook his head and continued, "The upper and lower boundaries of the screening interval are not a fixed value, but change linearly with the air pressure... You understand."
However, even though Lu Zhou was quite confident in his abilities, he couldn't think of any good solution for a while.
The reactivity of lithium metal is no joke, it will explode at the slightest disagreement!
Lu Zhou thought about it carefully, recalled some of the contents of the report, nodded and said.
Taking a deep breath, Yang Xu continued: "Based on experimental analysis, we found that under a certain pressure difference, the gas on the high-pressure side of this type of porous silicon material can slowly transport molecules of a specific diameter to the low-pressure side. Our The project team immediately followed up on this research and successfully produced an exchange membrane capable of screening gas molecules in the 3.4-3.5A diameter range."
"follow me."
On the screen, the red dot marking nitrogen has penetrated the exchange membrane and contacted the lithium negative electrode.
Although the silicon material from the Institute of Computational Materials has indeed brought a lot of hope to research in this direction, if the problem of eliminating the passage of other impurity gases cannot be solved, this can only be regarded as an interesting interim result. , no more advanced than those ideas of putting an oxygen tank outside the battery.
"... When the surface pressure of the membrane reaches position A in the figure, oxygen begins to pass through the molecular exchange membrane and move toward the gas exchange chamber of the lithium-air battery. However, when the surface pressure continues to increase as the pressure difference increases, it reaches position B. , nitrogen will also begin to pass through the exchange membrane..."
Since this guy became the director of the Institute of Computational Materials, he has led many large projects, and he has also solved many problems in materials science for Jinling Institute of Advanced Studies.
Not to mention the technical cost of controlling the air pressure difference to such an accurate level, from a safety perspective, it is absolutely impossible for them to allow the redox reaction system in the lithium-air battery to run on such an unstable steel wire. .
"What's there to thank me for..."
Unfortunately, Chen Yushan guessed wrong this time.
"It's not good at all." The expression on Yang Xu's face was a little bitter, and he shook his head and continued, "The upper and lower boundaries of the screening interval are not a fixed value, but change linearly with the air pressure... You understand."
Before finding Lu Zhou, the research team on the lithium-air battery project led by Yang Xu had been stuck on this bottleneck for almost half a year, and so far there has been no progress at all.
After stroking his chin and thinking for a long time, he could only give an ambiguous answer.
"But in fact, when the air pressure difference begins to gradually change from A to B, some nitrogen molecules are already penetrating inward at a slow rate."
"We try to increase the surface air pressure on one side of the exchange membrane, and molecules of a specific diameter will pass through the channels in the molecular exchange membrane at a certain rate... "
After hearing these words, Lu Zhou finally showed a clear expression on his face.
Lu Zhou: "Isn't that great?"
His intuition told him that if even he couldn't do it, who in the entire Institute for Advanced Study would have hope of solving this problem, probably only Professor Lu, one of the founders of computational materials science.
On the screen, the red dots and green dots distributed on the right side of the molecular exchange membrane began to gather towards the surface of the molecular exchange membrane, as if they had found an outlet for pouring.
As for the content of the request for help...
However, even though Lu Zhou was quite confident in his abilities, he couldn't think of any good solution for a while.
"We have been stuck on this bottleneck for half a year," Yang Xu shook his head, "We have tried every possible method..."

The key reason why lithium-air batteries are difficult to develop is that lithium metal is too reactive. And the impurities that need to be eliminated are too lazy.
As for whether the air pressure on both sides can be maintained at a constant value to ensure that only oxygen passes through the exchange membrane...
After returning to Jinling, Lu Zhou had indeed made plans to start a new round of retreat, and had indeed made up his mind to "never step out of the house until the Riemann Hypothesis was solved." However, in reality, things were really different. Too much.
It is about the lithium-air battery project initiated two or three years ago.
"...I'll go back and think about it. If there is any new progress, I will tell you."

"I can think of ways to deal with a series of impurities including water molecules, carbon dioxide, and even carbon monoxide. There are also gases with weak contents such as sulfur dioxide that can be easily dealt with, but only nitrogen... is really difficult to deal with. , It’s like a swarm of flies that can’t be driven away.”
However, even though Lu Zhou was quite confident in his abilities, he couldn't think of any good solution for a while.

He asked Wang Peng to drive him to the Jinling Institute for Advanced Study. As soon as Lu Zhou stepped into the laboratory, he was grabbed by the arm by Yang Xu, who looked in pain.
Speaking of which, Lu Zhou was quite surprised. Until the end of last year, he had been able to see news about significant progress in lithium-air battery research from reports from the Institute of Computational Materials.

If this thing can be researched, it will be a market worth tens of thousands or trillions!
"...I thank you!"
As for whether the air pressure on both sides can be maintained at a constant value to ensure that only oxygen passes through the exchange membrane...
"...I thank you!"
Lu Zhou: "Isn't that great?"
Yang Xu has made it very clear that the movement of the upper and lower boundaries of the entire screening interval changes linearly with the change of the air pressure difference on both sides.
If it really doesn't work, he can only declare that this technical route has failed and think about other possible directions.
Even if he is not very interested in money, the value behind this subject is worth giving him a try...
Lu Zhou: "Isn't that great?"
In short, this porous silicon-based molecular exchange membrane is like an elastic fishing net. The larger it is, the larger the mesh of the fishing net will be, and the more fish will slip through the net...
Hearing Yang Xu's "thank you", Lu Zhou didn't notice the despair deep in the heart of this "academic leader who had begun to doubt his life". Instead, he smiled sheepishly.
As for the content of the request for help...
As he spoke, Yang Xu held the mouse with his right hand and tapped it twice with his index finger.
If nitrogen is allowed to enter the circulation system of the lithium-air battery, the entire battery may be useless after only a few runs.
The person who called him for help this time was Yang Xu, director of the Institute of Computational Materials.
