"Judging from the calculation results, the energy density of solid-state batteries will be three times that of ordinary lithium batteries, but in order to achieve marketization, it is necessary to improve the generation efficiency and reduce production costs."

January 22, 2019, Jingzhou City, Jingzhou University, Institute for Advanced Study of Mathematics.

Xu Yun sat at his desk in his office, holding a pen in his hand and looking down at the scratch paper stacked on the table.

The whole person was lost in thought, muttering to himself.

The solid-state battery laboratory is in preparation, and he deliberately studies and analyzes the solid-state battery technology in his mind during this time, and when he encounters problems, he will go to the library to find materials. In this way, when we thoroughly understand all the technologies and other specific experiments, we can successfully complete the manufacturing of solid-state battery prototypes and optimize the production method.

In addition, he has begun to write relevant academic papers, ready to set off a revolution in the entire battery industry.

Unlike traditional lithium-ion batteries, metal solid-state batteries use glass compounds made of metals such as lithium and sodium as conductive substances to replace the electrolyte of traditional lithium batteries.

Greatly improve the energy density of the battery.

Because of this, it is safer and has the characteristics of small size and strong performance.

As the future development direction of batteries, all-solid-state batteries have always been the research goal of many industry companies and laboratories.

And in recent years, some progress has been made.

However, in order to realize the marketization of all-solid-state batteries, the performance of various products must be greatly improved while taking into account the cost.

Compared with traditional lithium-ion batteries, all-solid-state batteries have low production efficiency and high costs, which are simply unacceptable to the market and industry.

Of course, Xu Yun doesn't need to worry too much about this problem, with the metal all-solid-state battery technology rewarded by the mission, not only can it produce all-solid-state batteries with an energy density three times higher than that of lithium electronic batteries, but also the new production method can also achieve efficiency and scale.

It is conceivable that when this kind of battery enters the market, it will cause turbulent changes in the industry.

It is bound to usher in a major reshuffle.

At this time, just as Xu Yun put down the pen in his hand and was about to make a cup of tea and take a break to digest the calculations just now, he suddenly heard a familiar voice coming from outside the door.

"Good news."

"Xu Yun."

"Good news."

Xu Yun is definitely no stranger to this voice, but Tang Yanshan rarely has this kind of person who arrives before the voice.

Thinking of this, he hurriedly raised his eyes and looked in the direction of the door.

"Professor Tang."

"What makes you so happy?"

Soon Tang Yanshan's figure came into sight, he straightened up after receiving the water, and a smile appeared on the corner of his mouth.

I was quite curious about the news in Tang Yanshan's pass.

Tang Yanshan didn't pass on his coat, only a gray sweater on his body, and it could be seen that he rushed over directly after getting the news in the office.

"Don't you know?" Tang Yanshan was a little curious about Xu Yun's calm expression, and subconsciously asked a rhetorical sentence and walked directly to the computer next to him. Leaning over and quickly opening the website, he beckoned: "It's better for you to come and see for yourself." ”

was made by Tang Yanshan's move, and Xu Yun's curiosity was aroused.

Then he walked over and landed his gaze on the screen.

Probably because of the reason for being in the first place, he saw his name on it at a glance.

"It's ...... I'm on the hot search again? ”

muttered a word, and suddenly didn't know what to say in my heart.

In the last two months, he has been very low-key, spending most of his time at the Institute of Advanced Mathematics researching battery technology, except for participating in the construction of the laboratory and the recruitment of related scientific personnel.

The number of times I went out shopping with Chen Shihe was only a handful.

During the period, the company also made news because of this relatively large action, which caused heated discussions in the industry.

I really didn't expect that I hadn't calmed down for long, and I was inexplicably on the hot search on the whole network.

I really don't leave him any cooldown.

Tang Yanshan saw that Xu Yunzhen didn't know the specific situation, so he stopped selling Guanzi.

He sat down on the chair next to him, not hiding the joy on his face.

"Today the Wolf Prize in Mathematics was announced, with your name on it."

Although there is no age limit for the Wolf Mathematics Prize, Tang Yanshan is still self-aware of himself, and now he has no regrets to see his students successfully win the Wolf Mathematics Prize, not to mention that Xu Yun is naturally happier for the failure last year.

Xu Yun was focused on solid-state batteries during this time, and basically forgot about the announcement of the Wolf Prize in Mathematics.

However, he didn't have too many waves in his heart about this news.

Very simple.

It's only natural that he won't win an award.

As the proposer and prover of topological group theory, he has solved two world mathematical problems, the Hodge conjecture and the Goldbach conjecture, and was awarded the Fields Medal by the International Mathematical Union.

In this case, if you still don't win the Wolf Prize in Mathematics, then the prize can be removed from the seat of the authoritative mathematics prize.

I'm afraid that the gold content is not higher than the Gauss Award, the Chern Shiingshen Award.

Just as he was thinking about this, he heard a familiar shout outside.

"Congratulations, Xu Yun."

"Winning the Wolf Prize in Mathematics has brought glory to our mathematics community."

"It is estimated that the envy of those old guys in the imperial capital and Qinhua University is about to be crushed, they don't have such excellent students."

Qin Xiangxin was full of smiles, and when he mentioned his acquaintances in the mathematics departments of other universities, there were more wrinkles on his face.

It can be seen that he is really in a good mood now.

After walking closer and stopping, he casually asked, "The award ceremony is coming up in a few days, when are you going to leave?" ”

Xu Yun had his own plans, and when he heard this, he thought for a moment before responding.

"I probably won't have time to claim the prize."

At the moment, his energy is focused on the solid-state battery laboratory, and he needs to be involved in many things.

I really can't leave.

What's more, I have to go to Israel to receive the award, and I really don't have much thought of going.

Unlike last year, his achievements in mathematics no longer need to be proven by awards.

So it all depends on the mood.

What's more, the prize money of the Wolf Prize in Mathematics is relatively small, not to mention, even the medal is not gold.

When Qin Xiangxin heard Xu Yun's answer, the expression on his face was stunned for a moment, and then returned to normal.

"If you don't want to receive it, don't get it, I forgot that the Wolf Prize in Mathematics is really of little use to you now, and it is estimated that the Wolf Foundation will send the medal by mail at that time, and you will not be disqualified from winning the award."

He thought that Xu Yun regretfully failed to win the Wolf Mathematics Prize last year, and now he doesn't accept the award.

Young people.

If you are not vigorous, how can you call a young man.

Yesterday you ignored me, and today I told you to be unattainable.

For this reason, he did not persuade Xu Yun to do anything, but secreted the reaction to the Wolf Foundation based on experience.

Xu Yun naturally didn't know what Qin Xiangxin was thinking in his heart, in short, being able to understand it saved him a lot of trouble.

While the two of them were talking, Tang Yanshan's attention was attracted by the scratch paper stacked on the table.

After a few glances, a little surprise immediately appeared on his face.

The next second raised his head and looked at Xu Yun: "Why did you suddenly remember to study batteries during this time?" ”

"Don't you go to accept the award because of this?"

I directly told my guess in my heart, trying to determine if this was the case.

"Battery?"

Qin Xiangxin repeated the sentence in a lost voice.

As the dean of the Department of Mathematics, his main field of study is mathematics, and he really doesn't know much about battery-related situations.

But soon he seemed to think of something, and then moved on to another thing.

"Speaking of this, I suddenly remembered, did you come up with a new material some time ago, Academician Sun was full of praise for you, but when asked about the specific situation, he pretended to be deaf and dumb."

Xu Yun knew that Qin Xiangxin was talking about shaping fluorocarbon polymer coating materials.

It's just that this kind of material has been listed as a key confidential technology, and it is true that you will not know it without signing the relevant confidential documents.

Organizing the language a little, he explained the sentence briefly.

"Nothing."

"It's just a military material."

When he said this, his face was calm, as if he were talking about a trivial matter.

But when the words entered Qin Xiangxin's ears, it was different.

Military materials that can be kept secret by academicians, you don't have to think about it to know how important it is.

calmed down a little, and I only felt very emotional.

"I didn't expect to underestimate your talent." When he said these words, he looked very serious: "I thought you would become the greatest mathematician of this century, but now the world of mathematics is just one of the stops in your life." ”

For Qin Xiangxin, Xu Yun showed a very strong talent in mathematics at the beginning.

He hopes that Xu Yun will win the Fields Medal in mathematics and become an authoritative mathematician to lead the development of the domestic mathematics community.

Already quite a high rating.

But now it seems that this evaluation is not a little low.

Today, Xu Yun is no longer limited to theoretical mathematics, but has created miracles in a broader field.

and to overcome the lidar technology that has been stuck in the neck, to the military materials that are included in the key technologies.

The Wolf Prize in Mathematics does seem less important.

"Dean Qin, you're putting pressure on me, but without an understanding of mathematics, I can't easily get involved in other fields."

Xu Yun responded modestly to Qin Xiangxin's praise, and then turned his gaze to Tang Yanshan and answered truthfully.

"Recently, the company has set up several new laboratories, including solid-state battery research, so I have paid more attention to it during this time."

"I've seen the news for a while, but I didn't expect it to be true." Tang Yanshan obviously knew about the laboratory and highly praised Xu Yun's approach: "This is a very good thing, which can not only retain outstanding talents for the country, but also promote our technical discourse." ”

When he first saw the news, his first reaction was not to believe it, after all, as a professor, he knew all too well about the funding needed for the laboratory.

Basically, no company will choose to spend money in this area alone.

What's more, Deepin Technology is still on the rise.

Other companies only want to get more benefits and save costs, and it is rare for Xu Yun to do this.

"The higher the level of the lab, the more money is needed, and if there is a need, you can ask the school for help in time." Qin Xiangxin learned that Xu Yun was going to build a laboratory again, and after thinking about it for a while, he didn't forget to promise.
