Scholar’s Advanced Technological System

The deposit for the purchase of the instrument is directly from the overseas account of Star Technology to the account of the European instrument manufacturer. After Zhong Zhongming has signed the word there, the remaining balance will be credited to the other party’s account.

At the same time, the equipment purchased will be sent to Nanjing by a special transportation company.

The total value of the instruments on the purchase list exceeds 5000 million, which translates into RMB more than three billion.

Considering the importance of this batch of instruments, Qian Zhongming did not delay, and on the day of the job, he ordered the next day’s ticket and flew to Europe with Liu Bo.

Lu Zhou was not idle, and on the third day of Senior Brother Qian’s trip to Europe, National Quemoy University opened a seminar.

The specifications of this seminar are not small, not only the Professional Quemoy University’s Professor, such as Yanda, Shuimu, Folding, Aurora and other C9 alliance universities, and the Nanjing Science and Technology University and other 211 Polytechnics, Material Science, Professors in the field of organic synthesis, as well as engineers from battery companies such as BYD, also participated in the conference.

Unlike the academic conferences of the MRS conference, this seminar is semi-academic in nature and does not exchange research results, but rather discusses research and development.

In addition to the Scholar Professor who studies the direction of lithium materials, participants also represented representatives of national research funds, as well as representatives of new energy companies such as BYD and Sugi and project development engineers.

As for the subject of the discussion, it can be seen from the lineup of the participants that it is naturally a lithium-sulfur battery.

As an internationally renowned Scholar, the big cow who solved the problem of lithium dendrites, Lu Zhou naturally participated in the meeting.

The meeting started at 10 am, but it is only just nine o’clock. The conference room has been crowded and packed.

It seems that it is because it is very difficult to know the subject, the mission is arduous, everyone’s expression is very serious, and the atmosphere in the conference room is also very depressed. Even if you are full of people, you can’t hear too much.

Sitting in the seat with his famous brand, Lu Zhou sipped a bottle of mineral water and took a sip of the water before the start of the meeting to observe the expression on his face.

In general, the situation does not seem to be particularly optimistic.

About 9:30, Lu Lao and the next Chinese Academy of Sciences academicians whispered a few words.

Almost everyone has already arrived, and then the microphone is turned on, and the cleared scorpion started talking.

“Since everyone is here, we don’t waste precious time waiting.”

Stopped whispering, the meeting room was quiet, waiting for Lu old to continue.

“…Energy is the lifeblood of industry. Whoever has mastered new energy will have a grasp of the future. This mission is very difficult and is related to the strategic layout of our country in the field of new energy.”

“At the last meeting, the top executives of Beijing have decided to focus on lithium-sulfur batteries, but they need wisdom from others to solve more specific technical problems.”

“This seminar is mainly about solving problems.”

“If there is any good opinion, I hope that everyone can brainstorm and speak up and present their opinions.”

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

On the surface, this meeting seems to be useless. What everyone is discussing is not the existing results, but the solution to the problem. But in fact, the doorway of this is far from being as simple as the layman thinks.

National and corporate research funding is limited, and not all projects can apply for adequate research funding.

Generally speaking, if the country decides the general direction of lithium-sulfur batteries, the problem of lithium-sulfur batteries will be relaxed in the application of vertical issues, and other research topics such as lithium-ion batteries will be tightened.

The same is true for the study.

Solving the shuttle effect of lithium-sulfur batteries can be started from the positive electrode material, or it can be started from the electrolyte, and then subdivided, and thousands of methods can be separated.

However, the bureaucrats of the Ministry of Science and Technology and the Ministry of Finance do not understand academics.

But it doesn’t matter if you don’t understand, they don’t need to understand. In the decision-making process, they often refer to the opinions of some industry bulls, and make a macro direction in decision-making, giving priority to ensuring that sufficient research funding can be obtained for topics in this direction.

Under such macroeconomic regulation and control, there are always some potential research projects that can breed high-quality results.

It is for this reason that the importance of such a seminar has been highlighted.

From a personal point of view, everyone naturally hopes that their research direction can get more policies and financial support.

It is for this reason that although the atmosphere before the meeting was very depressed, the discussion was quite enthusiastic after the meeting began.

The first to get up and speak is the Wang Haifeng Professor from the big one.

After getting up, Professor Wang and the sly laughed, said.

“Since Director Lu said, everyone brainstormed and talked freely. Then I will throw a brick and talk about it, and talk about some of my ignorance.”

“Our research team found a highly ordered nanostructured carbon-sulfur positive structure in the experiment, which can use carbon structural framework to limit the dissolution of sulfur during charge and discharge, thus effectively curbing the shuttle effect.”

There was no empty talk, and Professor Wang came up with the existing research results and raised his persuasive power.

Regarding the advice of Professor Wang, Lu Lao immediately expressed his concern. The expression asked seriously: “What about cost? Is there energy density? Is this technology reliable?”

“The cost is not expensive, and the energy density is quite impressive. The theoretical energy density I measured in the laboratory is close to 2000Wh/kg, far exceeding the lithium-ion battery commonly used in the industry today. Related to thesis I am in Material Science In the top issue of Advanced-Materials, this technology is not perfect and needs to be improved.”

Paused, Professor Wang continues.

“In fact, the key to solving the shuttle effect of lithium-sulfur batteries is that the current mainstream practice in the academic world is to use porous carbon materials to block polysulfide ions and reduce the loss of sulfur. My suggestion is that we can adopt a similar approach. The focus of research and development is on sulfur-carbon composites.”

Lu Lao is seriously nodded.

The secret secretary sitting next to him is quickly making a meeting record in his notebook.

After the speaker finished, Professor nodded to the peers and sat down.

However, his stool was still not hot, and a calm and steady voice came from the seat of the Yanda Professor.

“I have something to say.”

Speaking from Academician Wu Shigang from Aurora, like Professor Wang, he is also a big cow in the field of Material Science.

Seeing this elderly, Lu Lao also said with respect.

“Sir Wu Academician please.”

After correcting the microphone, Academician Wu indulged for a moment and said.

“When I was involved in the 863 project, I have already considered carbon-sulfur composites when I studied the related issues of lithium-sulfur batteries. This strategy seems to be very effective academically, but the actual effect is very limited.”

“The research work in the laboratory is based on a small button cell, the electrode is very thin, the sulfur load is not high, and the total sulfur content is about a few milligrams. The actual battery has a large sulfur content, which is generally gram. Grade, and the electrode is very thick and the unit sulfur load is very high.”

“The lab is able to cycle 1000 times of sulfur/carbon composites, which can only be cycled several times in actual batteries, and sometimes even one time cannot be discharged.”

” Moreover, the most deadly common problem of carbon-sulfur composites is that the volumetric energy density is not high. If it is the battery of 3C products such as computers and mobile phones, it is better to use carbon-sulfur composite materials as the positive electrode. If it is a car or a bigger one. It’s hard to say something.”

The old mister has been doing this research since ten years ago, and because it is the engineer born in the school, it pays more attention to the practical value of a technology than the theoretically long-skilled Scholar.

Moreover, he is in the direction of solid electrolytes.

However, Professor Wang was not happy at all.

However, it is not him who is refuting, but another Professor who is engaged in the direction of carbon-sulfur composite materials, and it is justified.

“You are right, sulfur-carbon composites do have defects in this area, but in my opinion, these defects can be solved in repeated experiments. A year ago we all thought that lithium batteries were unstable. But now? Who can doubt the broad prospects of lithium batteries?”

Lu Zhou: …?

Lu Zhou, who didn’t want to get involved in the big cows, was sitting there and didn’t talk. The result was a shot inexplicably.

The meeting was very enthusiastic.

Although not as direct as the MRS meeting, it is so fierce, but with a little snack, you can hear the dark arrows in the words.

Sitting in the front row, Lu Zhou felt a sigh of relief.

Fortunately, the system’s scanning gun saved him a lot of research and development costs, and the technology of lithium dendrite also sold for a good price. Otherwise, at this moment, I am afraid that Brace oneself will join the battle.

Just then, another Professor spoke up.

“I will also say a few words.”

The speech was made by Sun Hongbiao Professor of Shuimu University.

In terms of lithium battery materials, Shuimu University ranks lower in the international rankings than Aurora and Yanda, but its influence is also quite large.

However, his speech is somewhat different from the big cows who spoke before.

I saw the old Professor gently coughing and said without hesitation.

“I noticed that the Foundation Professor has not spoken, but looking at his expression, it seems that he has a good idea about this problem. I have nothing to say when I get up, just want to hear his opinion.”

Lu Zhou 😕 ? ?
