The cash prize of the Chen Shengshen Mathematics Prize was 100,000 yuan, which was not much. Liu Yichen gave it to his mother.

International mathematics prizes range from US$10,000 to hundreds of thousands of US dollars, and the reward for solving a Millennium Puzzle is US$1 million.

It is unrealistic to make a fortune by relying on mathematics prizes. If you solve all the remaining six Millennium Problems, you will only get a prize of 6 million US dollars. A prize of 6 million US dollars seems like a lot. In a few years, you will be able to get a better villa in Beijing, Shanghai, Guangzhou and Shenzhen.

Can't even afford it!

The top mathematicians really want to make a lot of money. As long as they put aside their moral integrity, there are many ways to make a fortune. Liu Yichen does not expect to become a super rich man on the Forbes list by relying on his mathematics bonus. It is just for honor. Honor is more important than money.

.

Looking at the brightly lit capital below, Liu Yichen's eyes were very calm. He had never worried about money. He had a complete set of patents for lithium-sulfur batteries. As long as the patents were issued, even if he did not produce them himself, some battery giants would cry to the sky.

He was given huge sums of money, and he would be merciless just by collecting patents.

But now, patents are not issued so quickly, it will take time.

Liu Yichen is naturally waiting for a patent in vain. In the field of lithium-sulfur batteries, he can publish several sci papers.

However, a paper and applying for a patent are two different things. This requires experiments and detailed experimental data to support the paper. Otherwise, it will not be considered a major achievement at all.

For other people, they might go to the school laboratory to experiment and then conduct experiments. But Liu Yichen would never do that.

Because once you use the school's materials and equipment to write a paper, you only have the right to sign it, and the ownership belongs to the school.

In order to avoid patent disputes in the future because of the gold mine of lithium-sulfur batteries, which may cause some people to lose face, it is better to keep everything clean from beginning to end.

For this kind of experiment that is not too complicated, he directly asks the company to prepare a room for him as a laboratory. He only needs to make a list of the materials and instruments needed for other experiments, and it is easy to prepare them all.

While preparing for the experiment, Liu Yichen also began to prepare to recruit people. After all, he wanted to put it into production directly after the patent was issued.

Lithium-sulfur batteries have broad prospects and are extremely competitive. Whether they are used in mobile phone batteries, laptop batteries, new energy vehicle batteries, etc., they have a very broad market and there is no need to worry about selling them.

As for heavy assets, that is not a problem at all. As long as the patent is there, it is easier than anything else to get financing or loans.

On May 1st, which was Labor Day, Liu Yichen’s proof paper on the hail conjecture was finally published in the latest issue of "Annals of Mathematics".

Although you can download and watch it on arxiv, no one knows whether the preprint posted by Liu Yichen on arxiv is any different from the officially published paper, or whether there are any pitfalls.

There are a large number of papers on the arxiv website, but this does not mean that all the papers above are correct. On the contrary, there are many papers with problems on them. Many people think that the papers they have written are valuable.

Taking advantage of the trap.

During the May Day holiday, Liu Yichen did not go home or be in the library, but appeared in the laboratory prepared for him by the company.

During this time, he has fully understood the technology of transparent lithium-sulfur batteries, and also understood that the key to solving the problem of lithium dendrite growth in lithium-sulfur batteries lies in the processing of polydimethylsilane (PDMS) materials.

The key to the problem is the processing of PDMS materials. Untreated PDMS materials, even if they are coated on copper sheets, are of no use at all. How should the lithium dendrites rise or how they should explode?

Materials science is different from mathematics. The former requires summarizing experience in countless experiments and huge financial investment, while the latter can start research with just a piece of paper and a pen without considering the literature review. Most of the scientific research funds are spent

On travel expenses for meetings.

This is why a mathematician’s scientific research funding of 1 million is a lot. Of the 1 million scientific research funds, 500,000 is normally used by mathematicians to improve their lives, and the remaining 500,000 is used for scientific research, including participating in

Travel expenses for conferences, and bonuses to graduate students or other members of the team.

If you don't know anything about it, it is very difficult to make a qualified PDMS material. It often takes countless failures to prepare a qualified PDMS material.

From a certain perspective, chemical experiments and physical experiments themselves are a kind of trial and error experiments. Valuable experimental results are found and summarized during trial and error.

Once understood, the experiment was very simple. Even if Liu Yichen was not a chemistry major, he quickly prepared a qualified PDMS material—a bottle of waxy yellow gel—according to his understanding.

This thing looks like honey, but it is full of the texture of jelly. There seems to be nothing special on the surface, but taking a sample and observing its microstructure under an electron microscope, it is different from ordinary liquid polydimethylsiloxane.

The difference is huge.

Then, the rectangular copper foil prepared in advance was placed in the glue leveling machine, and the second most critical step in making electrode materials began - spin coating!

The coating droplets on the workpiece are fully spread on the surface of the workpiece.

This operation requires very high technical skills from the experimenters, and it is not as simple as applying a film on a mobile phone.

Uneven coating is likely to cause lithium ions to be unable to precipitate evenly on the negative electrode material. There is no need for lithium dendrites to pierce the separator. After several sets of charge and discharge cycles, it will become too crooked to be used.

.

An hour later, Liu Yichen finally succeeded in obtaining a precious piece of 'copper foil evenly coated with PDMS nanopore film'!

Looking at the copper foil clamped on the tweezers, he couldn't help but sigh.

This is a key technology of lithium-sulfur batteries, and currently no one else in the world knows about it except him.

It is such a thin piece of copper foil, but it is worth tens of thousands of gold!

After making the PDMS material, Liu Yichen began to make a simple battery, test the performance of the film, and accumulate data as support for the paper.

I connected the simple battery I made to the bk-6808 rechargeable battery performance tester, and then carefully placed it under a digital microscope.

The next step is to wait for experimental data.

Leave the laboratory and lock the door of the laboratory. This is extremely confidential stuff and must not be lost, even in the company.

"Mr. Liu, here are the latest financial statements and the research and development progress of the project. Please take a look." Financial Director Chen Yue saw Liu Yichen sitting down in the office and said with a smile.

Liu Yichen took the report and browsed it briefly. Originally, the funds in the company's account were over 100 million. Even though only the projects he had done had made money and the others had not yet generated income, the funds on the books were very abundant, and

Liu Yichen spent tens of millions of dollars to apply for an international patent for lithium-sulfur batteries, but even so, the company's book capital still reached 50 million yuan, without any debt.

As for the etc system he gave to the company to develop, the current development progress is only 2/3 complete, with 1/3 still in progress.

Liu Yichen muttered to himself that if he had done this etc system, it would have been completed long ago.

However, he could only accept this progress, because it was impossible for him to finish everything, which was unrealistic.

"Director Chen, how are the talks with the Ministry of Transportation going so far?" Liu Yichen asked.

For Huaxia's expressways, each province has an expressway administration authority. It is unrealistic to negotiate with each province. But they are in the capital. The most practical thing is to directly contact the Ministry of Transportation for cooperation, and work from top to bottom. Only in this way can we get the best results.

So as to solve the problem as quickly as possible.

Moreover, this kind of thing is mutually beneficial and win-win. The benefits for expressways are self-evident. It can greatly reduce the work pressure of expressway staff, compress the operating costs of expressways, speed up vehicles entering and exiting stations on expressways, and improve the operating efficiency of expressways.

"At present, a preliminary intention to cooperate has been reached, but the final cooperation will not be formalized until the development of the etc system is completed," Chen Yue said.

Liu Yichen nodded slightly. It was obvious that the Ministry of Transport was very cautious and wanted to wait until it saw actual results before cooperating.

To be honest, he is still very confident about the etc system, because in a few years the etc system will be initially tested at high speeds. Ten years later, more and more etc systems will be installed, and even many high-speed imports and exports will only retain one manual worker.

channel, and the rest become etc channels.

"Director Chen, do you know any financial talents? I want to set up a company in the new energy field and need talents in this area. Of course, there are other talents such as management, materials, etc. you can recommend to me." Liu Yichen looked at it.

To Chen Yue.

For lithium-sulfur batteries, Liu Yichen felt that it would be too much of a loss to leave the production to the international lithium battery giants and charge the patent fees himself, because in that case, China would make a lot of money away from these lithium battery giants. But it would be a waste to open a factory to produce it by yourself.

It’s different. I will have a huge say in lithium batteries, and this also means that China will have a huge say in lithium batteries.

The most important thing is that Liu Yichen is very clear about the broad prospects of new energy batteries. Looking at the CATL era ten years later, it has extremely eye-catching profits every year, and has created more than 100,000 jobs, directly driving the rapid development of nd city.

, at its peak, CATL’s market value exceeded 1.6 trillion yuan.

Only through industry can we save the country!

Only through industry can we strengthen the country!

Liu Yichen firmly believed this.

As for the huge cost of opening a lithium battery factory, Liu Yichen is not afraid of this. Although he does not have many assets, this era is an era of technology. As long as you have technology, you are not afraid of running out of money.

Now that the country is making large-scale investments, it can borrow large amounts of money if it has the technology, and it is not afraid of losing money, because lithium-sulfur batteries are not afraid of losing the market, but are afraid of not being able to keep up with production capacity.
