Scholar’s Advanced Technological System

“Do you want to borrow a lab?”

On the phone, after hearing Lu Zhou’s request, Prof. Li Rongen, who is analyzing the sample in the carbon nanomaterials laboratory, is doubtfully frowned.

Holding the phone, Lu Zhou said with a smile: “Yes, I found some interesting things when I was researching the literature. I want to use it in the lab. I might need a glue machine and a digital microscope.”

The reason is of course he compiled, although he has a good personal relationship with Professor Li, but he has not yet pushed himself to that extent. It is not doubtful that the character of Professor Li is just to avoid some unnecessary interest disputes that’s all.

After all, the value of this level of invention is not something that can be measured by an SCI.

Especially for the industry.

“That, let me say hello to the teacher in the lab. You can go directly to the 304 office in the lab building to find Wang Xianfu Professor.”

Although I was curious about Lu Zhou, who was engaged in high-energy physics, why did I go to do this kind of experiment, but Professor Li Rongen didn’t ask much, just as interested in hobby, I readily agreed.

If other people borrowed these equipments, he would still hesitate. If he was unfamiliar, he would refuse, but Lu Zhou was different. The last time he calculated thesis of Material Science, he helped himself a lot.

That is a project of more than one billion, and the direct and indirect economic benefits of tens of millions, not to mention one of the shareholders of New Zhongshan Materials, he is also a direct beneficiary.

In contrast, what is this little busy?

It’s just a matter of raising his hand, and even for him, he can’t even talk about human feelings.

Professor Li promised so refreshing, Lu Zhou was a little embarrassed.

I knew that the old mister was so good at talking. He also borrowed a bicycle with a digital microscope. He simply took the SEM scanning electron microscope and got it…

“Is there anything else?” Seeing Lu Zhou without speaking, Professor Li asked with a smile.

Lu Zhou shook his head. “No, thank you Professor.”

“You can’t do experiments alone? Or will I send Qian Zhongming to help you?”

Lu Zhou euphemistically thanked: “No, I want to try to do it myself.”

Of course he can’t agree.

The Hang Family like Senior Brother Qian is afraid to see the problem at a glance.

At that time, a lot of things can’t be explained by myself, no matter who designed the experiment, or how it all done.

This experiment is destined to be done by himself.

“That’s all right, you remember not to break the instrument, don’t blame me for going to your Boss.”

I know that Professor Li is joking with myself, Lu Zhou laughed, and packed the ticket: “No, you can rest assured! I guarantee what the lab will look like when borrowed, and when it comes back, what it looks like!”

……

I got the key from the king teacher of the 304 office, and Lu Zhou’s next plan was finally ready.

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

In order to solve this problem, the experimental ideas he designed are divided into two steps of making and spin coating.

However, the key to the problem remains in the processing of PDMS materials.

The untreated PDMS material, even if it is coated on a copper sheet, is of no use at all. How does the lithium dendrite rise or not, and the explosion still explodes.

Material Science is different from mathematics. The former must summarize the experience and countless capital investment in countless experiments. If the latter does not consider consulting the literature, the paper can be started with a pen and a penny. On the travel expenses of the meeting.

Lu Zhou thought for almost a whole day, did not find a suitable method, and finally had to take it down, spent 500integral, turned to system in this link, and got the recipe.

Looking at the integral that changed back to 1975, his heart was still hurting.

This thing is really expensive, his integral reward for several times, only 500 points, only enough to redeem a PDMS material processing method.

If this is to integrate the entire battery technology into the integral, I am afraid that the integral consumed is enough to “buy” a Goldbach conjecture.

Although it took a lot of integral, fortunately, the materials used in the formula can be found in the laboratory, and can not be found in the laboratory next door.

It took a full three days, after numerous failures, Lu Zhou finally succeeded in preparing a qualified PDMS material – a bottle of waxy gel.

This stuff looks like honey, but full of jelly texture. The surface does not seem to have anything special, but the sample is placed under an electron microscope to observe its microscopic structure, but with the usual liquid polydimethylsiloxane difference between Heaven and Earth.

Did not stop in this short-lived joy, Lu Zhou hot iron, put the prepared rectangular copper foil in the glue machine, began the second step of making electrode materials –

Spin coating!

The so-called spin coating method relies on the centrifugal force and gravity generated by the rotation of the workpiece to completely spread the coating droplets falling on the workpiece on the surface of the workpiece.

This operation is very technically demanding for the experimenter’s operation, not as simple as a mobile phone film.

Uneven coating, it is likely that lithium ions can not be uniformly deposited on the negative electrode material, do not use lithium dendrites to puncture the diaphragm, do a few sets of charge and discharge cycles, from their own can not be used.

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

After a full morning, he succeeded in obtaining a valuable “copper foil uniformly coated with PDMS nanoporous film”.

Looking at the copper foil sandwiched on the raft, Lu Zhou couldn’t help feeling.

If you know what this stuff is, what is the use, I am afraid that if you open a price of hundreds of millions of dollars, no one will be too expensive?

For a little while, Lu Zhou packed up the sample, including the remaining PDMS materials contained in the glass bottles of the drug, and they were all taken away.

There is still a final step left.

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

I have seen Lu Zhou from the Senior Brother Qian demonstration. This time I am working on it. Although I am not very skilled, I am basically familiar with it.

In another lab, Lu Zhou was slickly replaced with the white robes, and put his hand into the argon-filled glove box, carefully fixing the copper foil covered with the PDMS nanoporous film. On the battery mold.

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

As for the diaphragm, Lu Zhou has chosen the Celgard23253-Layer combination diaphragm as always.

In addition to the major changes in the anode material, the other materials are basically the “original people” of the last lithium dendrite observation experiment, and at most there is only a slight change in the amount of use.

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

It wasn’t until all the steps were completed that he took a sigh of relief and gently wiped the sweat from his forehead with his sleeves.

“Get it!”

Looking at the battery sample in his hand, Lu Zhou is full of excitement.

And, even a piousness that he did not expect.

Yes, it is piety.

As a scientific researcher, I am devoted to science.

This technology is likely to come from a civilization that is more advanced than all civilizations on Earth. The economic value behind it is much dimmer compared to its own existence.

Perhaps it comes from a battlefield ruin, or perhaps from a trash can next to an inconspicuous interstellar playground.

But no matter where it comes from, let it see the people from the wreckage, it is yourself.

Deeply took a deep breath, restrained the excitement of the heart, Lu Zhou connected the battery sample to the BK-6808 rechargeable battery tester, and then carefully placed under the digital microscope.

Everything is ready, all that remains to be done is just waiting.

I hope that the final result will not disappoint him.

Set a photo for 10 minutes, Lu Zhou turned on the battery tester, and then took a copy of the latest research on Polignac conjecture from the computer bag and quietly studied it.
