Scholar’s Advanced Technological System

"Do you want to borrow a lab?"

On the phone, after hearing the request of Lu Zhou, Professor Li Rongen, who was analyzing the samples in the carbon nanomaterial laboratory, frowned at the eyebrows.

Holding the mobile phone, Lu Zhou said with a smile: "Yes, I found some interesting things when I was studying the literature. I want to use it in the laboratory, and I need to use a homogenizer and a digital microscope."

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

After all, the value of this level of invention is not a sci can be measured.

Especially for the industry.

"That, let me say hello to the teacher in the lab. You go directly to the office of Lab 304 and look for Professor Wang Xianfu."

Although I was curious about Lu Zhou, who was engaged in high-energy physics, why did he ran to do this kind of experiment, but Professor Li Rongen did not ask much, only as a hobby, he 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 wrote a paper on computational materials, 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 Zhongshan New 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 refreshingly, Lu Zhou was a little embarrassed.

I knew that the old gentleman was so good at talking. He also borrowed a digital microscope such a bicycle. He simply took a sem scanning electron microscope and got it...

"Is there anything else?" Seeing Lu Zhou did not speak, Professor Li asked with a smile.

Lu Zhou shook his head and said: "No, thank you Professor."

"You can't do experiments alone? Or do 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.

Like the expert of Qian Shixiong, I am afraid that I can 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 himself. Lu Zhou smiled 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 teacher Wang of the 304 office. Lu Zhou’s next plan is 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 and mathematics are different. The former must sum up experience in countless experiments and huge capital investment. If the latter does not consider accessing the literature, one paper and one pen can start research. Most of the research funding is used. On the travel expenses of the meeting.

Lu Zhou thought for almost a whole day, and did not find a suitable method. In the end, he had to take a break and spent 500 points. He went to the system and got the recipe.

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

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

If this is to integrate the entire battery technology, I am afraid that the points consumed are enough to "buy" a Goldbach conjecture.

Although it took a lot of points, 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 bottle of waxy yellow gel of qualified pdms material.

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 it is different from the ordinary liquid polydimethylsiloxane.

Did not stop in this short victory joy, Lu Zhou hot iron, put the prepared rectangular copper foil in the glue machine, began the second step of making the electrode material the most critical

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?

In the heart for a little while, Lu Zhou packed the samples, including the remaining pdms materials contained in the glass bottles of medicines, 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.

Lu Zhou, who has already seen Qian’s brother’s demonstration, has operated this time. Although he is not very skilled, he is basically familiar.

In the other lab, Lu Zhou slammed into 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 celgard2325 three-layer composite 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 samples in his hand, Lu Zhou was 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 the 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 Star Trek.

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

Taking a deep breath and restraining the excitement in the heart, Lu Zhou connected the battery sample to the bk-6808 rechargeable battery tester and carefully placed it 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 the Polignac conjecture from the computer bag, quietly studied.
