Scholar’s Advanced Technological System

“You want to borrow the lab? ”

On the phone, after hearing the request from the Ark, Professor Lee Rong-eun, who was analyzing samples in the carbon nanomaterials laboratory, frowned suspiciously.

Holding the phone, the ark laughed and said, "Yes, I found something interesting while researching the literature, and to operate it again in the lab, you might need to use a glue dispenser and a digital microscope. ”

Of course, he made it up. Although he and Professor Lee had a good personal relationship, he had not been so sure. I don't doubt Professor Li's character, I just want to avoid some unnecessary conflicts of interest.

After all, the value of this level of invention is not measurable by an SCI in a region.

Especially for industry people.

“Well, I'll say hello to the lab teacher and you can go straight to Professor Wang Xianfu's office in Experimental Building 304. ”

Although curious as to why the Ark was running to do this kind of experiment, Professor Lee Rong-eun didn't ask much, just as a hobby, and said yes with pleasure.

If someone else borrowed the equipment, he would hesitate more or less and refuse without being familiar with it, but the ark was different. His last paper on computational materials did him a huge favor.

It's a billion-dollar project, with direct and indirect economic benefits of tens of millions, not to mention as one of the shareholders of Zhongshan New Materials, he is also a direct beneficiary.

In contrast, what does this little favor count for?

It's just a show of hands. It's not even human for him.

Professor Li promised to be so cheerful, the ark was a little embarrassed.

I knew this old gentleman was such a good speaker. What else did he borrow from a bicycle like a digital microscope? Why not borrow a SEM scanning electroscope?

“Anything else?” Seeing that the Ark had not spoken, Professor Li asked with a smile.

The ark shook its head: “No, thank you, Professor. ”

“Can you do the experiment alone? Why don't I send Chung-ming money to help you? ”

"No, I'd like to try to do it myself. ”

Of course he couldn't agree.

Professionals like Brother Qian are afraid to spot the problem at a glance.

A lot of things couldn't explain themselves by then, no matter who designed the experiment or how all of this was done.

This experiment was meant to be done only by his own hands.

“Well, just remember not to break the instrument, so don't blame me for going to your boss. ”

Knowing that Professor Li was joking with himself, Ark chuckled and packed his tickets: “No, don't worry! I guarantee you what the lab looks like when you borrow it, when you return it, or what it looks like! ”

……

With the keys from Teacher Wang of the 304 office, the next plan for the Ark can finally begin.

According to the technique of reversing the scanner gun, the key to solving the lithium branch crystal growth problem is in the treatment of polydimethylsilane materials.

To solve this problem, he designed the experimental thinking into two steps: making and spinning.

However, the key to the problem remains the handling of PDMS materials.

The untreated PDMS material, even if applied to copper sheets, is of no use at all, how the lithium branch crystal rises or how, the explosion still explodes.

Materials differ from mathematics in that the former must draw lessons from numerous experiments, as well as a huge financial investment, while the latter, without considering access to the literature, can begin research on a paper and pen by pen basis, with half of the funding for scientific research being spent on travel to meetings.

The Ark thought for almost the entire day and did not find a suitable method, and finally had to give it a hard heart, costing 500 points, to get help with the system and get the formula to make it.

Looking back at the 1975 score, he still had a cruel pain in his heart.

This thing is so expensive, he only gets 500 points for a couple of missions, just enough to redeem a PDMS material for handling.

If you put the whole battery's technology together based on points, I'm afraid you're spending enough points to “buy” a Gothic guess.

Although it takes a lot of points, fortunately, the materials used in the formula can be found in the lab or borrowed in the lab next door if not found.

After three full days and countless failures, the Ark finally successfully prepared a qualified PDMS material - a waxed yellow gel.

This thing looks like honey, but it's full of jelly. There seems to be nothing special about the surface, but the sampling is placed under an electron microscope to observe its microstructure, which differs from the usual liquid polydimethylsiloxane day by day.

Without making more stops in this brief joy of victory, the ark hit the iron while it was hot, placing the prepared rectangular copper foil in the glue dispenser and starting the most critical second step of making the electrode material--

Spin it!

The so-called spin coating method relies on the centrifugal force and gravitational action generated by the rotation of the workpiece. The coating droplets that will fall on the workpiece will be distributed throughout the coating process on the surface of the workpiece.

This operation is highly technical for the experimenter and is not as simple as a mobile phone film.

The application is not uniform, it is likely that lithium ions will not be uniformly analyzed on the anode material, and the diaphragm will not be pierced with lithium branch crystals. Several sets of charging and discharging cycles will be made, and crooked dates will no longer be available from the individual.

Although previously tested with other materials, the ship failed quite a few times.

It took him all morning to get a valuable "copper foil evenly coated with PDMS nanopore film”.

Looking at the copper foil clamped on the tweezer, the heart of the ark is filled with emotion.

If I knew what this thing was, what use would it be? I was afraid that if I offered hundreds of millions of dollars, no one would be offended?

After a moment of complacency, the Ark packed the samples, including the remaining PDMS materials in the pharmaceutical glass bottle, and took them all away.

Now there is one last step.

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

I've seen Brother Qian demonstrate the ark, this time I can't talk about skill, but I'm basically familiar with it.

Coming to another lab, the ark splendidly replaced the white coat "robe” and reached into a glove box filled with argon gas, carefully securing the copper foil covering the PDMS nanopore film to the battery mold.

As for the binder, which is sodium carboxymethylcellulose and butylene rubber, the collector is aluminum foil and the cathode active material is still the LiFePO4 commonly used in lithium-ion batteries today!

As for the diaphragm, the ark, as always, opted for the Celgard2325 three-layer combined diaphragm.

In addition to the major modification of the anode material, the other material is basically the "original squad horse" of the last lithium-crystal observation experiment, with at most only minor changes in usage.

After completing the final assembly operation, the ark still dared not to take samples carefully and close the valves of the glove box.

He took a long breath and gently rubbed the sweat in front of his lower forehead with his sleeve until he had completed all the steps.

“Done! ”

Looking at the battery samples in your hand, the heart of the ark is filled with excitement.

And a hint of piety that he hadn't even anticipated himself.

Yes, it's pious.

As a scientific researcher this, devout to science.

This technology is likely to come from a civilization that is more advanced than all civilizations on Earth combined, and the economic value hidden behind it diminishes considerably compared to its very existence.

Maybe it's from a battlefield ruin, maybe it's from a trash can next to some blind interstellar playground.

But whoever brings it back from the wreckage, wherever it comes from, is himself.

Taking a deep breath and restraining the excitement in your heart, the ark attached the battery sample to the BK-6808 rechargeable battery tester and carefully placed it under a digital microscope.

Everything is ready and all that remains is waiting.

Hopefully the final result will not disappoint him.

Set for 10 minutes to take a photo, the ark turned on the battery tester, and then took a piece of literature from the computer bag on Polynyak's guess of the latest research progression and quietly drilled it.
