Scholar’s Advanced Technological System

The deposit for the purchase of the instrument is directly from Startech's overseas account to the account of the European instrument manufacturer. After Qian Zhongming goes there to sign, the remaining balance will be placed on the other party's account.

At the same time, the equipment purchased will also be delivered to Jinling through specialized transport companies.

The total value of the instruments on this purchase list is over $50 million, which translates into more than $300 million for RMB.

Given the importance of the equipment, Qian Zhongming did not procrastinate either. On the day of his inauguration, he ordered a ticket for the next day and flew with Liu Bo to Europe.

Nor was there any leisure time on the side of the Ark. On the third day of Brother Qian's trip to Europe, Jinling University held a seminar.

The seminar was not only attended by professors from Jindao, such as the C9 alliance universities such as Yan Da, Shui Mu, Folding, Zhen Dan, and a group of 211 Polytechnic Colleges such as Jinling University of Technology, professors in the field of materials science and organic synthesis, as well as engineers from battery companies such as BYD.

Unlike academic conferences such as the MRS conference, the seminar was semi-academiological in nature and did not exchange research results, but rather discussed the direction of research and development.

In addition to scholarly professors studying the direction of lithium-electric materials, participants included representatives of the National Science Research Fund, as well as representatives of new energy enterprises such as BYD and Cedar Co, and project R&D engineers.

With regard to the subject matter of the discussion, it can be seen from the array of participants that it is naturally lithium-sulfur batteries.

As an internationally renowned scholar, Big Bull solved the lithium branch crystal problem, and the ark naturally participated in the meeting.

The meeting began at 10 a.m., but it was only just 9 a.m., and the room was already full of people and seats.

It seems to be because of the difficulty of knowing the subject, the enormity of the task, the seriousness of everyone's expressions and the depressed atmosphere in the conference room. Even if it's full, you can't hear a lot of voices.

Sitting in his nameplate seat, the ark twisted the mineral water bottle developed and sipped it, watching the expression on the faces of his colleagues while it was empty before the meeting began.

Overall, the situation does not seem particularly optimistic.

Around 9: 30, Lao Lu and the adjacent Chinese Academician exchanged two sentences in silence.

Almost everyone was there, so he held the microphone straight and cleared his voice.

“Now that we're all here, let's not waste precious time waiting. ”

Stopped whispering and calmed down in the conference room, waiting for Lu Lao to continue.

“… energy is the lifeblood of industry, and whoever masters new energy masters the future. This time the task is daunting and has to do with the strategic layout of our country in the field of new energy. ”

“At the last meeting, Shanghai's top executives had decided to focus on lithium-sulfur batteries, but wisdom was needed on how to solve more specific technical problems. ”

“The main discussion of this seminar was the idea of solving the problem. ”

“If you have any good opinions, I hope that you will be able to brainstorm and speak up and present your opinions. ”

At the meeting, Lu Lao, as the moderator of the meeting, made a brief opening statement.

On the face of it, the meeting seemed useless, and people were discussing not existing outcomes, but ways to solve problems. But in fact, the doorway is far less simple than outsiders think.

State and enterprise funding for scientific research is limited and not all projects are eligible for adequate research funding.

In general, if a country decides on the general direction of lithium-sulfur batteries, the subject matter of lithium-sulfur batteries will be relaxed in applications for vertical subjects, and other research topics such as lithium-sulfur batteries will be tightened.

The same is true in the study.

Solving the shuttle effect of lithium-sulfur batteries can be done from cathode materials, electrolytes, and then subdivided down into thousands of different methods.

However, bureaucrats in the Ministries of Science and Technology and Finance do not understand academia.

But it doesn't matter if they don't understand, and they don't have to. When making decisions, they tend to take into account the opinions of some industry bulls and set a macroscopic direction in their decision-making, giving priority to ensuring that subjects in this direction receive adequate research funding.

Under such macro-regulation, there are always potential research projects that incubate high-quality results.

It is precisely for this reason that the importance of such seminars has been highlighted.

From a personal perspective, we naturally hope to receive more policy and financial support for our research direction.

It is precisely for this reason that, although the atmosphere prevailed before the start of the meeting, the discussions were quite lively after the beginning of the meeting.

It was Professor Wang Haifeng who took the lead.

After getting up, Professor Wang smiled and said.

“Now that Director Lu has said it, everyone brainstorms and speaks freely. Then I'll throw the brick and tell you about some of my awkwardness. ”

“Our research team found in the experiment a highly ordered nanostructured carbon-sulfur cathode structure capable of limiting the dissolution of sulfur during charging and discharging using a carbon-material structural framework, thus effectively containing the shuttle effect. ”

There was no blank words, and as soon as Professor Wang came up, he came up with the research results that already existed, which increased his persuasion.

With regard to Professor Wang's opinion, Lao Lu immediately took it seriously and asked: “What about the cost? And the energy density? Is this technology reliable? ”

“The cost is not expensive, and the energy density is considerable, and the theoretical energy density I measured in the lab is close to 2000Whkg, far higher than the lithium-ion batteries now commonly used in industry. I sent this paper to Advanced-Materials, a top-of-the-line material journal, but it's not perfect and needs to be improved. ”

After a pause, Professor Wang continued.

“Indeed, the key to solving the shuttle effect of lithium-sulfur batteries is the prevailing practice in academia to use porous carbon materials to block polysulfur ions and reduce sulfur dissolution loss. My suggestion is that we could use a similar approach, focusing research and development on sulfur carbon composites. ”

Lao Lu nodded seriously.

The secretary sitting next to him was a quick record of the meeting on his notebook.

After his speech, Professor Wang smiled and nodded to his colleagues and sat down.

However, his stool was not hot, and a calm and steady voice came from Professor Yan's seat.

“I have something to say too. ”

Speaking from the Academician Wu Shigang of Zhen Dan, like Professor Wang, was also a big bull in the material sciences.

Seeing this old man, Lao Lu also said respectfully.

“Go ahead, Master Wu. ”

Hold the microphone correctly, Wu Yancheng sighed for a moment and said.

“I actually considered carbon sulfur composites when I was involved in Project 863 to study issues related to lithium-sulfur batteries. This strategy appears to be academically effective, but has very limited practical impact. ”

“Laboratory research is based on small button-type batteries with thin electrodes, low sulfur loads, and total sulfur levels of approximately several milligrams. Actual batteries have a high sulfur content, typically grams, with thick electrodes and high unit sulfur loads. ”

“Laboratories are able to cycle sulfur carbon composites 1,000 times, only a few times in the actual battery, sometimes not even once. ”

“Moreover, the most lethal common disease in carbon sulfur composites is the low volume energy density. If it's a 3C product battery such as a computer or cell phone, it's hard to say if it's a car or something bigger if it's made of carbon sulfur composite. ”

The old man had been doing this research for 10 years, and because he was an engineer-born scholar, he focused more on the practical value of a technology than a theoretically competent scholar.

And he's doing solid electrolyte directions.

However, Professor Wang did not like it at all.

But it wasn't him who rebutted it, it was another professor who was working on the direction of carbon sulfur composites, and it was plausible.

“You're right, sulfur carbon composites do have flaws in this regard, but in my opinion, these flaws can be addressed in repeated experiments. A year ago we all thought lithium batteries were unstable, but now what? Who can doubt the vast prospects of lithium batteries? ”

Ark: …?

I didn't want to get involved in the bulls' torn ark, sitting there without talking, and I somehow got shot.

The meeting was very lively.

Though not as straightforward as the MRS conference tore down, with a little refreshment, you can hear the spear arrow in the words.

In the heart of the canoe sitting in the front row was a shout of emotion.

Fortunately, the systematic scanning gun saved him a lot of research and development costs, and the lithium-crystal technology sold a good price. Otherwise, at this moment he, I'm afraid, will have to join the battle with his scalp.

At this point, another professor spoke.

“Let me also say something. ”

This statement was made by Professor Sun Hong Bin of Shui Wood University.

In terms of lithium-electric materials, Shui Wood University ranks slightly lower internationally than Zhen Dan and Yan Da, although its influence is also considerable.

However, his statement was somewhat different from that of the bulls who had spoken earlier.

The old professor coughed softly and spoke slowly.

“I have noticed that Professor Lu has not spoken, but by the look on his face, it seems that he is already full of bamboo on this issue. I got up with nothing to say, I just wanted to hear his opinion. ”

Ark:????
