The hardware level of the Frick Chemistry Laboratory is indeed worthy of being among the top in the United States. Princeton, with its deep pockets, is not only willing to spend money on professors, but also invests unambiguously in instruments.
I remember the last time I had a liver attack was this time last year.
Almost a week has passed since the first experiment started.
He consciously moved the latest MACCOR high-precision battery testing system over. Connie looked at Lu Zhou and smiled honestly.
"What's the situation like with sample No. 15?"
All the money spent on purchasing the machine was recorded in his account.
Where are you going now
After staring at Connie, Lu Zhou suddenly felt that this kid was not as honest as he looked at all.
"This guy has the best battery testing system in the entire Frick Chemistry Laboratory. I borrowed it for you!"
I remember the last time I had a liver attack was this time last year.
As for the remaining steps, they are not much different from Lu Zhou’s lithium battery experiment.
Where are you going now
It seems that his assistant has no hope for this experiment.
Lu Zhou: "Actually, we don't need such a good battery testing system..."
As for the cathode material, it takes a little more thought.
Lu Zhou: "Actually, we don't need such a good battery testing system..."
Putting the instrument aside for the time being, Lu Zhou asked seriously, "Can you make battery samples?"
As for the cathode material, it takes a little more thought.
But it doesn't hurt that much.
Assemble the battery in the glove box, then connect it to the battery test system, and conduct a large number of charge and discharge tests to confirm the performance of these materials in the electrodes.
"This guy has the best battery testing system in the entire Frick Chemistry Laboratory. I borrowed it for you!"
Connie explained: "But you said that it is better to invest in instruments than to spend your budget on samples consumed by repeated experiments."
Before using the ball milling method to mix the hollow carbon balls with elemental sulfur, they must be dispersed in ethanol by adding surfactants such as polyurethane, and then mixed with elemental sulfur.
After taking the test once, Connie recorded the data in the experiment report and was suddenly stunned for a moment.
"Let's see... the 10% and 30% groups are already finished starting from 200 revolutions. The 20% group... it's unbelievable that it's 500 revolutions and it's still struggling."
"What about sample No. 23?"
"No..." Connie shook his head, swallowed and said, "The results are so good that it's hard to believe..."
Lu Zhou thought for a while and gave instructions: "You are responsible for samples No. 11 and 14, and I am responsible for samples No. 15 and 23. Mix the hollow carbon ball powder with elemental sulfur according to the mass fraction of 30%, 20%, and 10%. , make the positive electrode material, and then assemble the lithium battery, do you understand how to do it? "
But it doesn't hurt that much.
After staring at Connie, Lu Zhou suddenly felt that this kid was not as honest as he looked at all.
Lu Zhou: "Actually, we don't need such a good battery testing system..."
Not just hollow carbon spheres, but all carbon nanomaterials have similar troubles.
Because after that, he calculated it many times and came to the same result.
"Let's see... the 10% and 30% groups are already finished starting from 200 revolutions. The 20% group... it's unbelievable that it's 500 revolutions and it's still struggling."
Then he took another set of tests.
All the money spent on purchasing the machine was recorded in his account.
Not just hollow carbon spheres, but all carbon nanomaterials have similar troubles.
"No..." Connie shook his head, swallowed and said, "The results are so good that it's hard to believe..."
Simple mechanical stirring and grinding can only macroscopically mix the hollow carbon sphere agglomerates with the matrix powder, but are unable to disperse the agglomerates themselves.
In order to complete the final step of solving Goldbach's conjecture, Lu Zhou locked himself in a world of less than twenty square meters, completely immersed in the maze of numbers, looking for the final way out.
If it had been before, Lu Zhou would definitely feel distressed for a while.
"What about sample No. 23?"
Regarding such tragic experimental results, Lu Zhou couldn't help but start to wonder if there was something wrong with his theory.
"I know, I was just joking..." After dismantling the battery, Connie carefully handled the positive electrode material inside and measured its width changes with a vernier caliper.
Assemble the battery in the glove box, then connect it to the battery test system, and conduct a large number of charge and discharge tests to confirm the performance of these materials in the electrodes.
Lu Zhou: "Actually, we don't need such a good battery testing system..."
In order not to delay the work there, he needed to establish a mathematical model based on these data as soon as possible, and then formulate the next experimental plan.
But now...
As for the remaining steps, they are not much different from Lu Zhou’s lithium battery experiment.
Then he took another set of tests.
After taking the test once, Connie recorded the data in the experiment report and was suddenly stunned for a moment.
Well, waste was shameful, and he still felt a little sad.
If there was really something wrong with this theory, then he would have to face a difficult choice.
Connie stood at attention and puffed out his chest and said, "Of course!"

The hardware level of the Frick Chemistry Laboratory is indeed worthy of being among the top in the United States. Princeton, with its deep pockets, is not only willing to spend money on professors, but also invests unambiguously in instruments.
The current research and development of new materials is mainly based on the "scientific intuition" of researchers and a large number of repeated "trial method" experiments, using limited conditions to find a feasible method. If you can once again basically establish a set of theories that are applicable within a limited scope, you will be considered a very powerful person.
During this period of time, Lu Zhou basically spent the rest of the time in the laboratory except sleeping there.
But it doesn't hurt that much.
…

If there was really something wrong with this theory, then he would have to face a difficult choice.
Can hollow carbon nanospheres with a specific surface area in the [2326m2g-1, 3762m2g-1] range and a diameter in the [60nm-70nm] range really inhibit the diffusion of polysulfide compounds
Connie immediately said, "No problem, it's easy!"
Before using the ball milling method to mix the hollow carbon balls with elemental sulfur, they must be dispersed in ethanol by adding surfactants such as polyurethane, and then mixed with elemental sulfur.
Connie, who also had dark circles under his eyes and was standing by the scanning electron microscope, shook his head with a somewhat depressed expression, "The last group was completely scrapped, and almost all the sulfur elements were deposited on the surface of the carbon material. You can come and take a look. , looks very spectacular..."
All the money spent on purchasing the machine was recorded in his account.
Lu Zhou thought for a while and gave instructions: "You are responsible for samples No. 11 and 14, and I am responsible for samples No. 15 and 23.

There is no skill involved in any of these jobs.

Things seemed to all come together.

…
Almost a week has passed since the first experiment started.
There is nothing to say about the anode material. Because the synthesis process is simple, the combination of modified PDMS film and copper core lithium sheet is not only the standard in the industry, but also the standard in major materials science research institutes.

It seems that his assistant has no hope for this experiment.
Well, waste was shameful, and he still felt a little sad.
"No..." Connie shook his head, swallowed and said, "The results are so good that it's hard to believe..."
After looking inside through the transparent part of the battery case for a long time, Connie was stunned for a moment and came up with an ambiguous answer: "It seems like nothing has changed."
As for the cathode material, it takes a little more thought.
As if grasping the last straw, he restrained his excitement and asked: "What about the volume change of the negative electrode material?"
Once the volume expansion effect of carbon-sulfur composite materials occurs, it is very obvious and can be clearly observed even at the macroscopic scale.
Regarding such tragic experimental results, Lu Zhou couldn't help but start to wonder if there was something wrong with his theory.
Lu Zhou: "Actually, we don't need such a good battery testing system..."
Lu Zhou suddenly got excited and came back to his senses.

If this were the case, the three groups of samples numbered 11, 14, and 15 would have been almost completely wiped out.
In fact, the study of materials science itself has little skill.

"Failed?"
Lu Zhou suddenly got excited and came back to his senses.
I haven't finished this experiment yet, and I'm already thinking about my future.
"What about sample No. 23?"
Lu Zhou sighed softly: "Take the sample to a scanning electron microscope, take a picture, and then dispose of it... I have seen enough."
They are pretending not to know and continue to cheat the industry without conscience. You should still be a scholar with integrity, take the initiative to correct mistakes when you find them, and honestly contact the editorial department of "Journal of Shuimu University" to withdraw the manuscript...

"Measure the chemical composition of the electrolyte immediately!" Lu Zhou stood up from the office chair, his aura rising as never before, "Move quickly!"
If it had been before, Lu Zhou would definitely feel distressed for a while.
But it doesn't hurt that much.
Lu Zhou: "Actually, we don't need such a good battery testing system..."
In addition, two days ago, Yang Xu, who directed experiments at the Jinling Institute of Computational Materials, made a table of the effects of the specific surface area and pore size of hollow carbon spheres on data such as sulfur loading and the mass fraction of polysulfide compounds in the electrolyte, and sent it arrived at his mailbox.

I remember the last time I had a liver attack was this time last year.
After staring at Connie, Lu Zhou suddenly felt that this kid was not as honest as he looked at all.
Connie, who also had dark circles under his eyes and was standing by the scanning electron microscope, shook his head with a somewhat depressed expression, "The last group was completely scrapped, and almost all the sulfur elements were deposited on the surface of the carbon material. You can come and take a look. , looks very spectacular..."
"Let's see... the 10% and 30% groups are already finished starting from 200 revolutions. The 20% group... it's unbelievable that it's 500 revolutions and it's still struggling."
Not just hollow carbon spheres, but all carbon nanomaterials have similar troubles.
…
Well, waste was shameful, and he still felt a little sad.
"No..." Connie shook his head, swallowed and said, "The results are so good that it's hard to believe..."
The word struggle is an interesting word.
etc!
After taking the test once, Connie recorded the data in the experiment report and was suddenly stunned for a moment.
All the money spent on purchasing the machine was recorded in his account.
Once the volume expansion effect of carbon-sulfur composite materials occurs, it is very obvious and can be clearly observed even at the macroscopic scale.
He consciously moved the latest MACCOR high-precision battery testing system over. Connie looked at Lu Zhou and smiled honestly.
However, it seemed completely different to Lu Zhou.
In order to complete the final step of solving Goldbach's conjecture, Lu Zhou locked himself in a world of less than twenty square meters, completely immersed in the maze of numbers, looking for the final way out.
Once the volume expansion effect of carbon-sulfur composite materials occurs, it is very obvious and can be clearly observed even at the macroscopic scale.
It seems that his assistant has no hope for this experiment.
If this were the case, the three groups of samples numbered 11, 14, and 15 would have been almost completely wiped out.
Rubbing the sour brows, Lu Zhou put aside the ballpoint pen in his hand, looked at Connie who was observing the sample and asked.
I remember the last time I had a liver attack was this time last year.

It seems that his assistant has no hope for this experiment.
But now...
However, it seemed completely different to Lu Zhou.
"What's the situation like with sample No. 15?"
After looking inside through the transparent part of the battery case for a long time, Connie was stunned for a moment and came up with an ambiguous answer: "It seems like nothing has changed."
"What's the situation like with sample No. 15?"
As if grasping the last straw, he restrained his excitement and asked: "What about the volume change of the negative electrode material?"
In the case of the former, the feasibility is still very high. Even if he is proven wrong by others in the future, he can still use an "honest mistake" to excuse it, and no one will embarrass him. But thinking about the wasted social resources...
Then he took another set of tests.
Well, waste was shameful, and he still felt a little sad.
Can hollow carbon nanospheres with a specific surface area in the [2326m2g-1, 3762m2g-1] range and a diameter in the [60nm-70nm] range really inhibit the diffusion of polysulfide compounds
Because after that, he calculated it many times and came to the same result.
There is no skill involved in any of these jobs.
"What's the situation like with sample No. 15?"
After looking inside through the transparent part of the battery case for a long time, Connie was stunned for a moment and came up with an ambiguous answer: "It seems like nothing has changed."
The current research and development of new materials is mainly based on the "scientific intuition" of researchers and a large number of repeated "trial method" experiments, using limited conditions to find a feasible method. If you can once again basically establish a set of theories that are applicable within a limited scope, you will be considered a very powerful person.
"No..." Connie shook his head, swallowed and said, "The results are so good that it's hard to believe..."
Lu Zhou resisted the urge to swear: "Don't use visual inspection, take it apart and measure it with a vernier caliper! I want an accurate answer!"
All the money spent on purchasing the machine was recorded in his account.
They are pretending not to know and continue to cheat the industry without conscience. You should still be a scholar with integrity, take the initiative to correct mistakes when you find them, and honestly contact the editorial department of "Journal of Shuimu University" to withdraw the manuscript...

Simple mechanical stirring and grinding can only macroscopically mix the hollow carbon sphere agglomerates with the matrix powder, but are unable to disperse the agglomerates themselves.
Then he took another set of tests.
"I know, I was just joking..." After dismantling the battery, Connie carefully handled the positive electrode material inside and measured its width changes with a vernier caliper.
In fact, the study of materials science itself has little skill.
If this were the case, the three groups of samples numbered 11, 14, and 15 would have been almost completely wiped out.

Once the volume expansion effect of carbon-sulfur composite materials occurs, it is very obvious and can be clearly observed even at the macroscopic scale.
The hardware level of the Frick Chemistry Laboratory is indeed worthy of being among the top in the United States. Princeton, with its deep pockets, is not only willing to spend money on professors, but also invests unambiguously in instruments.
etc!

But now...
Well, waste was shameful, and he still felt a little sad.
If there was really something wrong with this theory, then he would have to face a difficult choice.

Looking at Connie lingering there, Lu Zhou frowned slightly.
Connie explained: "But you said that it is better to invest in instruments than to spend your budget on samples consumed by repeated experiments."
After taking the test once, Connie recorded the data in the experiment report and was suddenly stunned for a moment.
After staring at Connie, Lu Zhou suddenly felt that this kid was not as honest as he looked at all.
Then he took another set of tests.
I haven't finished this experiment yet, and I'm already thinking about my future.
Another set of tests...
As if grasping the last straw, he restrained his excitement and asked: "What about the volume change of the negative electrode material?"
Connie explained: "But you said that it is better to invest in instruments than to spend your budget on samples consumed by repeated experiments."
Not just hollow carbon spheres, but all carbon nanomaterials have similar troubles.
But it doesn't hurt that much.
If it had been before, Lu Zhou would definitely feel distressed for a while.
Another set of tests...
In fact, the study of materials science itself has little skill.
…
During this period of time, Lu Zhou basically spent the rest of the time in the laboratory except sleeping there.
"Let's see... the 10% and 30% groups are already finished starting from 200 revolutions. The 20% group... it's unbelievable that it's 500 revolutions and it's still struggling."

Although mathematical methods can reduce the workload of experiments, experiments are still essential...
"I know, I was just joking..." After dismantling the battery, Connie carefully handled the positive electrode material inside and measured its width changes with a vernier caliper.
"Failed?"
He consciously moved the latest MACCOR high-precision battery testing system over. Connie looked at Lu Zhou and smiled honestly.
This long-lost feeling is really nostalgic.
All the money spent on purchasing the machine was recorded in his account.
"No..." Connie shook his head, swallowed and said, "The results are so good that it's hard to believe..."
Lu Zhou suddenly got excited and came back to his senses.
After staring at Connie, Lu Zhou suddenly felt that this kid was not as honest as he looked at all.

…
"Measure the chemical composition of the electrolyte immediately!" Lu Zhou stood up from the office chair, his aura rising as never before, "Move quickly!"
Although mathematical methods can reduce the workload of experiments, experiments are still essential...
Rubbing the sour brows, Lu Zhou put aside the ballpoint pen in his hand, looked at Connie who was observing the sample and asked.
