Chapter 281 Whoever is the opponent can bind the Canglong with one hand
In 2014, new energy vehicles have not yet officially launched their efforts.
But practitioners in the new energy industry have long felt the huge opportunities under the calm.
The government has received continuous good news, and policies to promote the development of the new energy industry have been announced one after another.
And within the industry, there is an influx of large amounts of capital.
In just a short period of time, the number of companies in the new energy industry has doubled, and they are still being born at a faster rate.
For these situations, Galaxy Technology also has its own public opinion department that specializes in collecting this information.
So, Wang Donglai also knows these situations.
He did not take these companies seriously because he knew that he would be the final winner.
Lithium-sulfur battery, solid-state battery, graphene battery.
This is the path he is expected to take.
When the time comes, it will be the final controllable nuclear fusion. At that time, if miniaturization is carried out, that will be the moment when human beings truly go to the stars.
With this idea in mind, Wang Donglai still supports Galaxy Technology’s research on lithium-sulfur batteries.
That’s why he said such words to Chen Lingyue to show his support.
After finishing things in the office, Wang Donglai and Chen Lingyue went to the laboratory.
No matter what, Wang Donglai has always positioned himself as a scientist, not a businessman or a boss.
Using business is just to better complete his plan.
In addition, going to the laboratory has another purpose.
That is to let the researchers who have just joined the laboratory meet Wang Donglai, the prestigious scholar boss.
Wang Donglai specifically asked Chen Lingyue not to notify him in advance and wanted to see what the usual laboratory was like.
When I came to the laboratory, experiments were happening.
The content of the experiment may be very complicated for people outside this major, and they may not be able to understand or understand it.
But, for professionals, it's very simple.
Watching the experimenters in the laboratory busy working, Wang Donglai looked calm and did not express any opinions.
The focus is not on the people, but on their operations, as well as the experimental steps and processes.
These researchers are the seniors from Tangdu Jiaotong University who came back from abroad.
Not only because of trust in his alma mater, but also because Galaxy Technology offers generous salary packages.
Don’t look at the bald eagle’s prosperity, but 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 workers may seem glamorous, but in fact they are under great pressure.
Compared to China, the ceilings for technical jobs are similar.
In the Bald Eagle, except for a small number of biochemical environmental materials that can live well, the rest can only barely survive.
What's more, although the bald eagle is prosperous, it still costs a lot to maintain a decent life.
In comparison, several seniors and seniors who went abroad in their early years came to Galaxy Technology after being contacted by the school.
Wang Donglai and Chen Lingyue did not deliberately hide themselves, so soon, several researchers on the lithium-sulfur battery project saw Wang Donglai.
“Boss!”
Although they were Wang Donglai's seniors and seniors, they didn't pretend to be so, and instead called Wang Donglai boss.
"Seniors and sisters, you don't have to be so polite. You have already done me a great favor by coming back to my country." It’s time, I’ll invite some seniors to have a casual meal.”
Wang Donglai did not act condescending or domineering, but said to them cordially.
There are five people in total, all students from Tangdu Jiaotong University.
The oldest among them was a graduate of the 90th class, named Lu Tu. At this moment, he took the initiative and said: "Then we will have a hard time refusing the hospitality!"
Soon, a few people came to a restaurant and sat down. .
As soon as he sat down, Wang Donglai shook hands one by one and said with a smile: "Several seniors must have seen the country's support for new energy, so if the project we are researching can succeed, For you and me it is A win-win result.”
“Here, I hope that everyone can work together to overcome difficulties and create brilliance.” Wang Donglai said these two words and immediately mobilized everyone present. human emotions.
"Mr. Wang is right. With such a good opportunity and several of them being relevant professionals, there is a great chance of achieving a breakthrough."
Chen Lingyue also followed up and said.
Even though they knew that these words were pleasant to say, several people couldn't help but smile on their faces.
"By the way, don't call me boss, just call me Dong Lai!"
Wang Donglai suddenly thought of something and said this to several people.
"I think there is a more appropriate title. Now universities across the country know that our school has produced the youngest genius professor. I think it is more appropriate to call him Professor Wang. To other people, this is just a title, but let's put it down. It’s different for you, it’s a record-breaking honor.”
Although Lu Tu has been abroad for ten years, he has not learned the hypocrisy and exaggeration of Westerners.
These words were very well said, and they immediately caused several other people to nod their heads in approval.
After a few more pleasantries, Wang Donglai brought the topic to the research and development of lithium-sulfur batteries.
“I heard Brother Chen introduce the idea of using hollow carbon balls to solve lithium-sulfur batteries, but you guys are in person, so I’d better listen to your ideas.”
As Wang Donglai said these words, the atmosphere turned from the previous cheerfulness to seriousness.
Lu Tu is the oldest, but he also has the richest resume. He has been to Harvard and worked in several large factories. He has the deepest understanding of this aspect and the most sophisticated technology.
So, you guys looked at me, I looked at you, and decided to let Lu Tu answer first. "Compared with traditional lithium-ion batteries, lithium-sulfur batteries can provide higher energy density, up to 2600Whkg-1. In addition, sulfur also has the advantages of high natural reserves and strong environmental tolerance, so this makes lithium-sulfur batteries Become the energy source for future long-range vehicles and large-scale energy storage systems"
"However, lithium sulfur. There are still many problems for the successful application of batteries, such as the poor conductivity of elemental sulfur and solid reduction products, the volume change process during cycling and the so-called polysulfide shuttle effect. Specifically, through the repeated oxidation and reduction of soluble sulfides. The shuttle effect caused is the main reason for the low Coulombic efficiency of the battery and poor electrode cycle stability.”
"In order to solve these problems, a large number 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 scaffolds for sulfur."
"But among these carbon materials, porous carbon is unstable, carbon nanofibers are too complex, and graphene technology is difficult. Only hollow carbon balls have good effects, high feasibility and moderate cost.”
“In view of these advantages, we chose hollow carbon balls”
Lu Tu said a lot. , not only introduced the technical difficulties to Wang Donglai, but also introduced the relevant experimental conditions, and gave the reasons why he and others chose hollow carbon spheres.
No one who listens will have any opinion.
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, which is a very potential Promising application direction, choosing this point proves that all seniors and sisters do have real materials.”
“For the current stage. Do you have any ideas about the work?”
Hearing Wang Donglai’s question, Lu Tu said: “We are currently collecting the specific surface area and pore size of hollow carbon spheres, as well as the sulfur loading capacity of the electrolyte. "Influence on the mass analysis data of polysulfide compounds."
After finishing speaking, Lu Tu hesitated for a moment, as if he had something to say.
This scene seemed familiar.
Before Lu Tu could say anything, Wang Donglai shook his head slightly and said in a funny voice: "Brother Chen gave me a suggestion just now, saying that it is such a simple job for you to do. Overkill is a waste of talent, so I think We need to outsource the work of collecting data."
When Wang Donglai said his unspoken thoughts, Lu Tu was shocked at first, and then calmed down after a while, because he felt that he should be guessing. Here comes Wang Donglai’s answer.
Unexpectedly, what Wang Donglai said next was beyond his thoughts.
“Brother Chen’s proposal is for the good of the company. He wants to save costs for the company and to use everyone’s talents more efficiently.”
"But I refused, because this data collection work seems simple, but as a researcher, I cannot ignore it."
"Because all our experiments are based on accurate data, if the data is not enough To be precise, the experiments based on it are undoubtedly like the moon in the water and the flowers in the mirror."
"So, I thought of another way, which is to have one of you lead the interns from Tangdu Jiaotong University to do the data collection work, which can not only cultivate talents, but also save manpower, and ensure the accuracy of the data. "
“I wonder what the seniors think?”
After Wang Dong finished speaking, he waited for their answers.
And several people did not keep Wang Donglai waiting for a long time, and said loudly: "Professor Wang, this is a good idea!"
"The juniors and girls of the school are really blessed. If only we could have such a good idea in the past good opportunity It’ll be good if you know it.”
“Forefathers planted trees, and later generations took advantage of the shade. This is a great kindness from Professor Wang!”
Wang Donglai smiled calmly after listening to the words of several people. Earned with pride.
For lithium-sulfur batteries, Wang Donglai does not value solid-state batteries.
Therefore, after thinking for a moment, he said: "Actually, we don't have to be limited to the direction of hollow carbon spheres."
"I am here to express my position. In my opinion, scientific research It is a process of discovering gold and refining gold, which requires time, funds, and persistence. . ”
“Some laboratories and scientific research institutes are only willing to study projects that can see success, and are not willing to invest in some high-risk projects, but Galaxy Technology is different. I support you. Do useful trials and experiments."
"Lithium-Sulfur Batteries. It is one of the key projects that our company values, so we can be bold and take a broader view.”
“For example, we can create a unique graphene-like carbon nanocage and use it as a base. As sulfur carriers in high-rate, long-lived LSBs, carbon nanocages are composed of Surrounded by multiple layers of graphitized sp2 carbon, the diameter of the inner cavity is set to about 3-5nm, so that the large void volume can be used to load high-load sulfur nanoparticles into the graphene carbon cage unit using the solution method to achieve efficient dispersion of sulfur. , give full play to its electrochemical activity ”
"For another 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 the hollow using the capillary principle. Carbon, to solve such problems, we can use hollow porous carbon spheres HPCS as the carbon carrier, and use isopropyl alcohol IPA or N-methane for the sulfur solution. Preparation of 2-pyrrolidone NMP or CS2 ”
“Also, porous hollow carbon nanospheres functionalized with Co atoms as bifunctional sulfur hosts can also be tried! ”
“ In the process of scientific research and experiments, it is not a bad thing to try more!”
Wang Donglai mentioned several experimental directions in one breath.
The people who listened to his words also fell into deep thought.
If it were ordinary people, a few people might just listen to it, but it would be different if Wang Dong said it out loud.
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 parallel imports that are praised as experts.
I have real information in my stomach, but as soon as Wang Donglai mentioned it, I started to make rigorous predictions and speculations in my mind.
The more they speculated, the more excited and excited everyone became.
Because they found that if they followed what Wang Donglai said, they would most likely achieve a breakthrough.
When I thought of this, several people felt like they had thorns in their butts, and they became restless.
Wang Donglai also saw the changes in the expressions of several people, but he did not let them go. Instead, he changed the topic.
"Senior Lu, you have probably seen a lot during your years abroad. Do you think domestic academics are lagging behind compared to foreign countries?"
Wang Donglai has no answer to this question. After all, he has never worked abroad.
Even with the domestic academic atmosphere and environment, he didn't have much exposure.
Lü Tu’s mind was full of the research direction Wang Donglai just mentioned. At this time, when he heard Wang Donglai ask this question, he suppressed his thoughts, pondered for a while, and said aloud: "Foreign experts from abroad The advantage in development is too great. We are in a catching-up position and will naturally fall behind.”
“In many fields, domestic development is very fast. , can completely catch up with foreign advanced levels quickly, and even surpass foreign countries in some fields, but there are still some that are lagging behind.”
“To achieve a suitable ratio, it should be two points higher. , four points to catch up, four points to fall behind!”
“This is just my estimate, not necessarily accurate”
Hearing what Lu Tu said, Wang Donglai's eyes were bright, his tone was calm, but with a hint of uplifting pride, he said aloud: "We will not fall behind forever, it is all temporary, if we complete a breakthrough in new energy , they can throw the gasoline cars they have developed for hundreds of years into a place of eternal destruction in one fell swoop, and start again on a new track. Run, it’s obvious who will win!”
“Come on everyone, we carry the great responsibility of rejuvenating the motherland on our shoulders! Our research results will affect the world in the next few decades or even hundreds of years! Standard.”
