When I am reborn, I just want to be a top student

Chapter 281 Who is the opponent? Bind the blue dragon with one hand

In 2014, new energy vehicles had not yet officially taken off.

However, practitioners in the new energy industry have long sensed the huge opportunities beneath the calm.

The official has released a series of good news, and policies to promote the development of the new energy industry have been announced one after another.

And within the industry, a large amount of capital is pouring in.

In just a short period of time, the number of companies in the new energy industry has doubled, and is still emerging at a faster rate.

For these situations, Galaxy Technology also has its own public opinion department, which is dedicated to collecting this information.

So, Wang Donglai also knew about these situations.

He didn't take these companies seriously because he knew he would be the ultimate winner.

Lithium-sulfur batteries, solid-state batteries, graphene batteries.

This is the route he plans to take.

When the time comes, it will be the final controlled nuclear fusion. At that time, if it is miniaturized, that will be the moment when mankind truly steps towards the galaxy.

With this idea in mind, Wang Donglai is still very supportive of Galaxy Technology's research on lithium-sulfur batteries.

That's why he said those words to Chen Lingyue to show his support.

After finishing their work in the office, Wang Donglai and Chen Lingyue went to the laboratory.

No matter what, Wang Donglai has always positioned himself as a scientist rather than a businessman or a boss.

He uses business only to better accomplish his plans.

In addition, there is another purpose for going to the laboratory.

That is to let the few researchers who have just joined the laboratory meet Wang Donglai, the renowned scholar boss.

Wang Donglai specifically asked Chen Lingyue not to notify him in advance, as he wanted to see what the laboratory looked like on a normal basis.

When I arrived at the laboratory, an experiment was being conducted.

The content of the experiment may be very complicated for people outside this major, and they may not be able to understand it.

But for professionals, it is very simple.

Watching the laboratory technicians busy at work, Wang Donglai looked calm and did not express any opinions.

The focus is not on people, but on their operations, as well as the steps and processes of the experiment.

These researchers were the seniors who were called back from abroad by Tangdu Jiaotong University.

It is not only out of trust in my alma mater, but also because Galaxy Technology offers generous salary packages.

Even though the Bald Eagle is well-developed, it is a capitalist country after all. If you really want to live a good life, you must be an upper-class capitalist.

The middle-level white-collar class may seem glamorous, but in fact they are under tremendous pressure.

Compared with domestic conditions, the ceilings for technical jobs are similar.

In Bald Eagle, except for a few who can live comfortably, the others can only barely survive.

What’s more, although the bald eagle is developed, it is very costly to maintain a decent life.

In comparison, several senior students who went abroad in their early years came to Galaxy Technology after receiving contact from the school.

Wang Donglai and Chen Lingyue did not deliberately hide themselves, so soon, several researchers in the lithium-sulfur battery project saw Wang Donglai.

"boss!"

Although they are Wang Donglai's seniors, none of them acted in an airy manner and instead addressed Wang Donglai as "boss".

"Seniors, you don't have to be so polite. You have already helped me a lot by coming back to my company."

"I was quite busy recently, but I happened to have some time today, so I'll treat a few seniors to a simple meal."

Wang Donglai did not act superior or overbearing, but spoke to them in a friendly manner.

There are five people in total, all of whom are students from Tangdu Jiaotong University.

The oldest among them was from the 90th class, named Lu Tu. He took the initiative to say, "Then we can't refuse your kindness!"

Soon, they came to a restaurant and sat down.

As soon as they sat down, Wang Donglai shook hands with everyone and said with a smile: "I believe that the seniors have already seen the country's support for new energy, so if the project we are researching can be successful, it will be a win-win result for you and me."

"Here, I hope everyone can work together to overcome difficulties and create brilliance."

Wang Donglai's two sentences immediately aroused the emotions of several people present.

"Mr. Wang is right. With such a good opportunity and all of you being relevant professionals, there is a great chance of achieving a breakthrough."

Chen Lingyue also spoke up immediately afterwards.

Even though they knew that these words were just for the sake of sounding nice, several people couldn't help but smile.

"By the way, don't call me boss, just call me Donglai!"

Wang Donglai suddenly thought of something and said this to the few people.

"I think there is a more appropriate title. Now all colleges and universities in the country know that our school has produced the youngest genius professor. I think it is more appropriate to call him Professor Wang. For other people, it is just a title, but for you it is different. It is an honor to break a record."

Although Lu Tu had been abroad for more than ten years, he did not learn the hypocrisy and exaggeration of Westerners.

These words were very well said, and immediately caused the other people to nod in approval.

After a few more pleasantries, Wang Donglai turned the topic to the research and development of lithium-sulfur batteries.

"I've heard Brother Chen introduce the idea of ​​using hollow carbon spheres to solve the problem of lithium-sulfur batteries, but since you're in person, I'd still like to hear your ideas."

As Wang Donglai said this, the atmosphere changed from cheerful to serious.

Lu Tu is the oldest, but has the richest resume. He has been to Harvard and worked in several large companies. He has the deepest understanding in this area and the most sophisticated skills.

So, everyone looked at each other and decided to let Lu Tu answer first. "Compared with traditional lithium-ion batteries, lithium-sulfur batteries can provide higher energy density, up to 2600Wh kg-1. In addition, sulfur has the advantages of high natural reserves and strong environmental tolerance, which makes lithium-sulfur batteries a source of energy for future long-range vehicles and large-scale energy storage systems."

"However, there are still many problems for the successful application of lithium-sulfur batteries, such as the poor conductivity of elemental sulfur and solid reduction products, the volume change process during the cycle and the so-called polysulfide shuttle effect. Specifically, the shuttle effect caused by the repeated redox of soluble sulfides is the main reason for the low Coulombic efficiency of the battery and the poor cycling stability of the electrode."

"To address these issues, a lot of experiments have been conducted within the industry, using various carbon materials, such as porous carbon, carbon nanofibers, hollow carbon spheres and graphene, as conductive supports for sulfur."

"But among these carbon materials, porous carbon is unstable, carbon nanofibers are too complex, and graphene technology is difficult. Only hollow carbon spheres have good effects, strong feasibility, and moderate cost."

"Given these advantages, we chose hollow carbon spheres."

Lu Tu spoke a lot in a very eloquent manner, introducing the technical difficulties to Wang Donglai, the relevant experimental conditions, and the reasons why he and others chose hollow carbon spheres.

Anyone who hears this will have no objection.

Wang Donglai naturally had no objection, but continued: "Well, I understand what you said."

"Hollow carbon spheres and sulfur form a composite material to solve the shuttle effect. This is a very promising application direction. Choosing this proves that you seniors are really talented."

"Do you have any ideas about the current work?"

Hearing Wang Donglai's question, Lu Tu said, "We are currently collecting data on the effects of the specific surface area and pore size of hollow carbon spheres on sulfur loading and mass analysis of polysulfide compounds in the electrolyte."

After saying this, Lu Tu hesitated for a moment, as if he had something to say.

This scene seemed familiar.

Before Lu Tu could finish his words, Wang Donglai shook his head and said with amusement, "Brother Chen just gave me a suggestion, saying that it would be a waste of talent to let you do such a simple job, so he wanted to outsource the data collection work."

When Lu Tu heard Wang Dong express his unspoken thoughts, he was startled at first, but then he calmed down because he felt that he should have guessed Wang Dong's answer.

Unexpectedly, what Wang Donglai said next was beyond his expectations.

"Brother Chen's proposal is for the good of the company. It is intended to save costs for the company and to bring out your talents more efficiently."

“But I refused because this data collection task, although seemingly simple, cannot be ignored as a researcher.”

"Because all our experiments are based on accurate data. If the data is not accurate enough, the experiments based on it will be like the moon in the water or the flower in the mirror."

"So, I thought of another way, which is to have one of you lead the interns from Tangdu Jiaotong University to collect data. This can not only cultivate talents, but also save manpower, and the accuracy of the data can be guaranteed."

"I wonder what the seniors think?"

After Wang Dong finished speaking, he waited for their responses.

The few people didn't let Wang Donglai wait for long, and said, "Professor Wang, this is a really good idea!"

"The younger students in the school are so lucky. If only we had such a good opportunity back then."

"One who plants trees will enjoy the shade. Professor Wang's action is a great kindness!"

Listening to what they said, Wang Donglai smiled calmly, but he didn't feel complacent about it.

Wang Donglai does not attach as much importance to lithium-sulfur batteries as solid-state batteries.

So, after thinking about it for a while, he said, "Actually, we don't have to limit ourselves to the direction of hollow carbon balls."

"I want to make a statement here. In my opinion, scientific research is a process of discovering gold and refining it. It takes time, money, and persistence."

“Some laboratories and research institutes are only willing to study projects that can be successful and are unwilling to invest in high-risk projects, but Galaxy Technology is different. I support you to make useful attempts and experiments.”

"Lithium-sulfur batteries are one of the key projects that our company values, so we can be bolder and look at a broader range of issues."

"For example, a unique graphene-like carbon nanocage is made as a sulfur carrier in high-rate, long-lifetime LSBs. The carbon nanocage is surrounded by multiple layers of graphitized sp2 carbon, and the inner cavity diameter is set to about 3-5nm. In this way, the large void volume can be used to load high-load sulfur nanoparticles into the graphene carbon cage unit by solution method, so as to achieve efficient dispersion of sulfur and give full play to its electrochemical activity."

"For example, in the process of loading sulfur into hollow carbon, a relatively neglected factor is that the compatibility of molten sulfur or sulfur solution with carbon is low or medium, making it difficult to completely inject sulfur into hollow carbon using the capillary principle. To address this problem, we can use hollow multi-hole carbon spheres HPCS as carbon carriers, and the sulfur solution is prepared with isopropyl alcohol IPA or N-methyl-2-pyrrolidone NMP or CS2."

"Also, porous hollow carbon nanospheres functionalized with Co atoms as bifunctional sulfur hosts can also be tried!"

"During scientific research, it is not a bad thing to try more!"

Wang Donglai listed several experimental directions in one breath.

The people who heard his words fell into deep thought.

If it were an ordinary person, a few people might just listen to it and let it go, but when Wang Dong said it, it was different.

Everyone knew Wang Donglai's research talent in this area and did not dare to be careless at all.

In addition, several of them are experts in this field, not the kind of good-for-nothings who are touted as experts by others.

He had some real stuff in his mind. As soon as Wang Donglai mentioned it, he began to make rigorous estimates and speculations in his mind.

The more they speculated, the more excited and thrilled everyone became.

Because they found that if they did as Wang Donglai said, there would be a high probability of a breakthrough.

When they thought of this, they felt like their buttocks were covered with thorns and they couldn't sit still.

Wang Donglai also noticed the changes in their expressions, but he did not let them go. Instead, he changed the topic.

"Senior Lu, you have been abroad for so many years, and you must have seen a lot. How much do you think the academic field in China is still lagging behind that in foreign countries?"

Wang Donglai has no answer to this question, after all, he has never worked abroad.

He has not had much exposure to the domestic academic atmosphere and environment.

Lu Tu's mind was full of the research direction Wang Donglai had just mentioned. When he heard Wang Donglai's question, he suppressed his thoughts, pondered for a moment, and said, "Foreign countries have too great a first-mover advantage. We are in a catching-up position, so we will naturally fall behind."

"In many areas, China is developing very fast and is fully capable of catching up with the advanced level of foreign countries. In some areas, we have even surpassed foreign countries, but there are still some areas where we are lagging behind."

"To make a proper ratio, it should be two points to surpass, four points to catch up, and four points to lag behind!"

"This is just my estimate, it may not be accurate!"

Hearing what Lu Tu said, Wang Donglai's eyes were bright and his tone was calm, but with a hint of pride, he said: "We won't lag behind forever, it's only temporary. If we can make a breakthrough in new energy, we can destroy their gasoline cars that have been developed for hundreds of years. It's obvious who will win when we start again on a new track!"

"Come on, everyone. We are shouldering the heavy responsibility of making our country great again! The results of our research will affect international standards for decades or even hundreds of years to come."
