Points:5000

Looking at his attributes on the system, Liu Yichen's lips curled up slightly. He did not expect that he would win the Ramanu Gold Award. The system was so powerful that it awarded him 3,000 points.

"If I win the Fields Medal, wouldn't it mean more reward points?" Liu Yichen couldn't help but wonder.

This time he discovered that winning awards can lead to points rewards. According to his guess, the higher the gold content of the award, the more points will be awarded.

And by winning the Ramanu Gold Award this time, you not only received a 3,000 point reward, but also received a random lottery opportunity.

"System, lottery!" Liu Yichen was immersed in the system. As he said lottery, a lottery disk appeared in the system interface. The roulette wheel was written with dense words, and the roulette wheel began to spin rapidly.

Liu Yichen stared at the lottery disc. This time he won the Ramanu Gold Award. Although it was a random reward, the reward he could get was very high.

"Stop!" Liu Yichen suddenly shouted stop as he felt a blissful feeling in his soul.

"Ding~~" The system's metallic voice sounded: "Congratulations to the host, you won the core patent of 'lithium-sulfur battery' in a random draw!"

Lithium-sulfur battery?

What is this stuff!?

However, according to Liu Yichen’s understanding, lithium-sulfur batteries should also be a type of lithium battery. Lithium batteries are good. When it comes to lithium-sulfur batteries, Liu Yichen doesn’t know, but he knows more or less about lithium batteries. He knows that lithium batteries are a type of lithium-based batteries.

A primary battery that uses metal or lithium alloy as the negative electrode material and uses non-aqueous electrolyte solution. Edison, the inventor of lithium batteries, became a rich man with this patent. With the development of microelectronics technology at the end of the twentieth century, miniaturized equipment

Increasingly, lithium batteries have also entered large-scale applications, such as mobile phones, laptops, etc.

Liu Yichen still remembers that in a few years, a company engaged in new energy will be born in Fujian Province - CATL. This is almost known as a model of a company revitalizing a prefecture-level city. And the batteries made by CATL seem to be the same.

It is a type of lithium battery.

Can't wait to check the computer, Liu Yichen began to search for information, and gradually Liu Yichen discovered that there are differences between lithium-sulfur batteries and lithium batteries.

Lithium-sulfur battery is a lithium battery that uses sulfur element as the positive electrode of the battery and metallic lithium as the negative electrode. Lithium-sulfur batteries that use sulfur as the positive electrode material have higher theoretical specific capacity of the material and higher theoretical specific energy of the battery, reaching 1675mah/g and 1675mah/g respectively.

2600wh/kg, which is much higher than the capacity of lithium cobalt oxide batteries widely used commercially (<150mah/g). Moreover, elemental sulfur is abundant on the earth, has the characteristics of low price and environmental friendliness, and sulfur is a kind of environmentally friendly battery.

Environmentally friendly elements, basically no pollution to the environment, is a very promising lithium battery.

"I didn't expect that this lithium-sulfur battery is still in the scientific research stage. It is a huge gold mine." Liu Yichen showed a bright smile on his face.

Obtaining all the technology for lithium-sulfur batteries means that this gold mine is in his hands, and all he needs to do now is to apply for a patent and build patent barriers.

Go your own way and leave others with no way to go. This is a very important principle taught to China by European and American teachers.

If it were anyone else, they might have to worry about the huge cost of applying for a patent, but Liu Yichen didn't need to at all.

"Haha, giants, I can only say sorry to you. You have invested huge amounts of money in researching lithium-sulfur batteries, but it has been completely wasted!" Liu Yichen thought that many giants would suffer heavy losses as a result, and the smile on his face couldn't help but become brighter.

Lithium-sulfur battery technology, to describe it as a gold mine is not an exaggeration at all, and even underestimates its value.

Long ago, lithium metal was abandoned by the industry as anode because the short circuit problem caused by dendrite growth turned the battery into an incendiary bomb and "exploded" a listed company with a market value of tens of billions.

However, the strong market prospect of lithium metal still attracts countless materials science laboratories, who are pouring in on this topic one after another.

At the corporate level, IBM even prepared a supercomputer for the lithium-air battery project to calculate the path of each gas molecule entering the battery unit to avoid gas blockage problems... Although it was later discovered to be a bottomless pit, it was ignored by the capitalists. Cut it off without mercy.

At the national level, major countries have invested tens of billions in this technology, but unfortunately they have not been able to break through this technology so far.

According to the information found by Liu Yichen, experts on lithium-sulfur batteries found that these patents in China are mainly patents applied by foreigners or foreign companies. So far, there are only 46 patents, but none of them are core patents.

As for internationally, although there are many patents related to lithium-sulfur batteries, they are all just beginning and belong to the research and development stage, and there are no truly useful patents.

This means that once Liu Yichen applies for a patent, it will soon build a patent barrier for lithium-sulfur batteries. From now on, only he can do this business, and others can only watch helplessly. Even if they want to get a share of the pie, they have to If you pay the patent fee obediently, you will be able to receive a generous fee from the patent fee alone.

"The system is so powerful this time. This is a huge surprise for me!" Liu Yichen secretly sighed.

In an extremely happy mood, Liu Yichen spent all of Ramanujan's US$15,000 on buying gifts. He always brought something back as gifts when he rarely went abroad.

The next day, Liu Yichen had just completed an international flight back to China.

After returning to China, Liu Yichen began to apply for patents. As a modern person, he understood the importance of patents very well.

He still remembers that among the winners of the 2019 Nobel Prize in Chemistry, there is a post-90s generation - John B. Goodenough. He has attracted much attention. At the age of 97, he is hailed by the industry as the "Leader of Lithium Batteries". Father', developed cathode materials such as lithium cobalt oxide and lithium iron phosphate. He and two other scientists successfully won the Nobel Prize in Chemistry for their great contributions to the field of lithium batteries and were able to share the prize of 9 million kronor equally.

For ordinary scientists, the amount of this bonus may be considered generous, but it is not comparable to the changes that Goodenough has made to the lithium battery industry and society as a whole, and the huge economic value it has generated. Because in

Due to lack of awareness of intellectual property protection at the forefront of scientific research and mistakes in patent layout, Goodenough, who really pushed lithium batteries into applications and markets, did not receive corresponding economic returns.

This is a naked example. As soon as the news was reported, many people complained about Goodenough, but this kind of thing is not uncommon in the academic world.

This is also the reason why Huaxia continues to teach students that education pays attention to patents.

Of course, applying for a patent takes a lot of time. It takes 6 months to 5 years to apply for an invention patent. Even if it passes the quick pre-examination, the invention will take 3-6 months to be authorized, even if the technology is a new material.

Energy has priority review, but it will take 3 months at the earliest to get a patent.

Liu Yichen can apply for domestic patents by himself, but this is not possible for international patents. He has to find a specialized agency. For this kind of professional agency, an invention patent costs US$6,000 in the United States alone, US$5,000 in the European Union, and US$5,000 in Japan.

Russia costs US$5,000, which means applying for one of these international patents in major countries costs US$21,000.

The high patent application fees made China not pay attention to patent applications in the past, because China was poor at that time and companies were reluctant to spend the money to apply for patents.

The result is that just to apply for these patents, Liu Yichen needs to pay a professional agency US$10 million.

And normally, it takes 1 to 2 years to get these patents!

After finishing the patent matters, Liu Yichen had to fly from the capital to Ludao, because the Chinese Mathematicians Conference would be held at Ludao University.

The Chinese Mathematicians Conference is the grandest event in the Chinese mathematics community and a grand ceremony in the Chinese mathematics community. Chinese mathematicians from all over the world gather together to exchange mathematics. Of course, this Chinese Mathematicians Conference is extraordinary. It will

Fa Hua Luogeng Mathematics Award, Chen Shengshen Mathematics Award, Zhong Jiaqing Mathematics Award.

These three major awards are also known as China's three major mathematics awards.

The objects of his awards are also different. For example, in order to commemorate the great achievements of Mr. Hua Luogeng, encourage the Chinese mathematics community to make outstanding contributions to the development of Chinese mathematics, and promote the development of Chinese mathematics, it was jointly established by the Chinese Mathematical Society and the Hunan Education Press.

The Hua Luogeng Mathematics Prize is selected and awarded every two years, and the winners are between the ages of 50 and 70.

Chen Shengshen Mathematics Award. This award was established to recognize the achievements of Professor Chen Shengshen and encourage young and middle-aged Chinese mathematicians to contribute to the development of Chinese mathematics. It is awarded to the Chinese Young and Middle-aged Mathematics Award who have made outstanding achievements in mathematics. This award is awarded to

Mathematicians under 50 years old.

The Zhong Jiaqing Mathematics Award was established to commemorate Zhong Jiaqing, the outstanding mathematics awarder who died young, and rewards the most outstanding master's and doctoral students in mathematics in China.

This time, Liu Yichen was also nominated for the Chen Shengshen Mathematics Award. Logically speaking, he should have come to Ludao yesterday with people from the School of Mathematics at Yanda. However, Liu Yichen always had a thorn in his heart about what happened last time, so he did not

We did not make the trip together, but purchased a plane ticket at our own expense to attend the Chinese Mathematicians Conference at Ludao University.

Of course, he did not stay in the hotel arranged by Ludao University, but at his home in Ludao. He called two days ago and his mother had already cleaned his room.

Staying in a hotel is not as comfortable as staying in your own home, even a five-star hotel can't compare!
