"You want to borrow a lab?"

On the phone, after hearing Lu Zhou's request, Professor Li Rongen, who was analyzing the samples in the carbon nanomaterials laboratory, frowned suspiciously.

Holding the phone, Lu Zhou said with a smile: "Yes, I found something interesting when I was researching the literature, and if I want to operate it in the laboratory, I may need to use a blender and a digital microscope." ”

The reason is, of course, that he made it up, although he had a good personal relationship with Professor Li, but he hadn't put his heart on it to that extent. It's not that I doubt Professor Li's character, it's just to avoid some unnecessary conflicts of interest.

After all, the value of an invention of this level cannot be measured by a single SCI.

Especially for people in the industry.

"That's okay, I'll say hello to the teacher in charge of the laboratory in a while, and you can go directly to the 304 office of the laboratory building to find Professor Wang Xianfu."

Although he was curious about why Lu Zhou, a person engaged in high-energy physics, went to do this kind of experiment, Professor Li Rongen didn't ask much, just regarded it as a hobby, and readily agreed.

If someone else borrowed these devices, he would have hesitated to some extent, and if he was not familiar with it, he might have refused, but Lu Zhou was different, his paper on computational materials science last time did him a great favor.

It is a project of more than one billion yuan, and the economic benefits brought directly and indirectly are as high as tens of millions, not to mention that as one of the shareholders of Zhongshan New Materials, he is also a direct beneficiary.

What's the point of doing this little favor in comparison?

It's just a gesture, and he can't even talk about human favors.

Professor Li agreed so happily that Lu Zhou was a little embarrassed.

I knew that this old gentleman was so good at talking, and he borrowed a bicycle like a digital microscope, so he simply borrowed an SEM scanning electron microscope......

"Anything else?" Seeing that Lu Zhou didn't speak, Professor Li asked with a smile.

Lu Zhou shook his head and said, "No, thank you, professor." ”

"Can you do experiments alone? Why don't I send Qian Zhongming to help you? ”

Lu Zhou politely declined: "No need, I want to try to do it myself." ”

He certainly couldn't have agreed.

An expert like Senior Brother Qian is afraid that he will be able to see the problem at a glance.

At that time, there are many things that cannot be explained by themselves, whether it is who designed the experiment or how it was all done.

This experiment was destined to be done only by himself.

"Okay, just remember not to break the instrument, or don't blame me for going to your boss to complain."

Knowing that Professor Li was joking with himself, Lu Zhou smiled and said, "No, don't worry!" I promise what the lab will look like when it is borrowed, and what it will look like when I return it! ”

……

After getting the key from Mr. Wang in the 304 office, Lu Zhou's next plan can finally begin.

According to the technology of the scanning gun reverse, the key to solving the problem of lithium dendrite growth is the treatment of polydimethylsilane materials.

In order to solve this problem, the experimental idea he designed was divided into two steps: fabrication and spin coating.

However, the crux of the problem is still the processing of PDMS materials.

Untreated PDMS material, even if it is coated on copper sheets, is useless at all, how lithium dendrites should rise or how they rise, and how they should explode or explode.

Materials science is different from mathematics, the former must sum up experience in countless experiments, as well as a huge amount of financial investment, while the latter does not consider the literature, a piece of paper and pen can start research, and most of the scientific research funds are used for travel expenses for meetings.

Lu Zhou thought about it for almost a whole day, but he didn't find a suitable method, so he had to be ruthless, spent 500 points, and asked for help from the system in this link and got the recipe for production.

Looking at the points that had turned back to 1975, he still felt a severe pain in his heart.

This thing is really expensive, and the point reward for his several tasks is only 500 points, which is only enough to redeem a PDMS material processing method.

If the technology of the entire battery is sorted out by points, I am afraid that the points consumed will be enough to "buy" a Goldbach conjecture.

Although it cost a lot of points, fortunately, the ingredients used in the recipe can be found in the laboratory, and those that cannot be found can be borrowed in the laboratory next door.

It took three full days and countless failures to finally successfully prepare a qualified PDMS material - a bottle of waxy yellow gel.

It looks like honey, but it's full of jelly texture. On the surface, it may not seem to be anything special, but when the sample is placed under an electron microscope to observe its microstructure, it is very different from ordinary liquid polydimethylsiloxane.

Without staying in this short period of victory, Lu Zhou struck while the iron was hot, put the rectangular copper foil prepared in advance, put it in the glue leveler, and began the most critical second step of making electrode materials——

Spin coating!

The so-called spin coating method is a coating process that relies on the centrifugal force and gravity generated when the workpiece rotates, and the paint droplets that fall on the workpiece are fully distributed on the surface of the workpiece.

This operation requires a lot of technical requirements for the experimenter, and it is not as simple as the mobile phone film.

The uneven coating is likely to lead to the inability of lithium ions to precipitate evenly on the anode material, and lithium dendrites are not used to puncture the separator.

Although it had been tried with other materials before, Lu Zhou still failed many times.

It took a whole morning to get a valuable piece of "copper foil evenly coated with PDMS nanopore film".

Looking at the copper foil clamped on the tweezers, Lu Zhou couldn't help but sigh in his heart.

If you know what this thing is, what's the use, I'm afraid that if you offer a price of hundreds of millions of dollars, no one will be too expensive, right?

After a short period of pride, Lu Zhou packed up the samples, including the remaining PDMS materials in the glass bottles of the drug, and took them away.

Now there's one last step left.

That is to make a simple battery, test the performance of this film, whether it is as magical as he imagined.

Lu Zhou, who has already watched Senior Brother Qian's demonstration, operates it by himself this time, although he is not very proficient, but he is basically familiar with it.

Coming to another laboratory, Lu Zhou changed into a white coat and "battle robe", put his hand into the glove box filled with argon, and carefully fixed the copper foil covered with PDMS nanoporous film to the battery mold.

As for the binder, the binder is sodium carboxymethyl cellulose and styrene-butadiene rubber, the current collector is aluminum foil, and the cathode active material is still LiFePO4, which is commonly used in lithium-ion batteries today!

As for the diaphragm, Lu Zhou, as always, had to choose the Celgard2325 three-layer combination diaphragm.

Except for the overhaul of the anode material, the other materials are basically the "original team" of the last lithium dendrite observation experiment, and at most there are slight changes in the dosage.

After completing the final assembly operation, Lu Zhou still did not dare to be careless, carefully took out the sample, and closed the air valves of the glove box.

It wasn't until he had completed all the steps that he let out a sigh of relief and gently wiped the sweat from his forehead with his sleeve.

"That's it!"

Looking at the battery sample in his hand, Lu Zhou's heart was full of excitement.

and, a hint of piety that even he himself had not anticipated.

Yes, it's piety.

As a researcher, he is a devotion to science.

It is likely that this technology comes from a civilization that is more advanced than all the civilizations on Earth combined, and the economic value behind it is much dwarfed compared to the meaning of its existence.

Maybe it came from the ruins of a battlefield, or maybe it came from a trash can next to some nondescript interstellar playground.

But no matter where it came from, the one who brought it back to light from the wreckage was himself.

Taking a deep breath and restraining the excitement in his heart, Lu Zhou connected the battery sample to the BK-6808 rechargeable battery tester, and then carefully placed it under the digital microscope.

Everything is ready, all that remains is to wait.

Hopefully, the final result will not disappoint him.

Set 10 minutes to take a photo, Lu Zhou turned on the power of the battery tester, then took out a document on the latest research progress of the Polygnac conjecture from his computer bag, and quietly studied it.
