December 10, 2021.

3 p.m. local time in Stockholm.

It's the annual Nobel Prize season again.

It's winter, snow is falling, and the altitude is high, so the sky in Stockholm is getting dark at 3 p.m.

But the whole city is in a scorching atmosphere like boiling oil.

In particular, the Stockholm Concert Hall, located in the heart of the city, is even more crowded.

Nearby streets have long been cordoned off, and the sides of the road are crowded with flag-waving Stockholm citizens and tourists from all over the world.

Among them, the most eye-catching is the overseas Chinese waving the five-star red flag.

This year, two Chinese won the award, which caused a great response among overseas Chinese.

And Pang Xuelin's achievements have also spread all over the world through major media around the world.

Especially after the success of the Golden Dragon battery project, the case of the United States detaining Qi Xin pushed Pang Xuelin's fame to the peak.

Some media even did such a survey on Pang Xuelin's global popularity, in the United States, as many as 75% of people have heard of Pang Xuelin's name, in Japan and South Korea, more than 80%, and in Europe, more than 70% of people know Pang Xuelin's name.

Coupled with Pang Xuelin winning the Nobel Prize at the age of 24, in a sense, Pang Xuelin has become one of the most famous scientists in the world.

Pang Xuelin sat in the car, looking at the Chinese people who were waving the five-star red flag and cheering all the way, and there was also a heat current surging slowly in his heart.

Although in his own opinion, it is nothing to be recognized by the Nobel Prize, after all, there is a system, and he even has the ability to reduce and weaken the authority of the Nobel Prize in the future.

But for the Chinese who have the Nobel Prize, this is a moment of national celebration.

The convoy stops in front of the famous Stockholm Concert Hall, a simple concert hall with 10 pillars leading from the ground to the eaves and a statue of Orpheus in front of the concert hall.

Pang Xuelin got out of the car, accompanied by Zuo Yiqiu and the organizer staff, and walked into the Stockholm Concert Hall.

However, the winners did not go directly to the lobby of the concert hall, but waited backstage.

For each winner, the organizer's staff will follow them and tell them the general process of the award ceremony.

In addition, Pang Xuelin was accompanied by a neatly dressed Swedish female college student, and he only needed to follow the female college student from behind the scenes to the stage and accept the award from the King of Sweden.

At four o'clock in the afternoon, solemn music sounded.

This year's Nobel Prize winner in literature was the first to appear, followed by the Physics, Chemistry, Medicine or Physiology, and Economics.

As for the laureate of the Peace Prize, it was awarded by the Norwegian Nobel Peace Prize Committee, and it has nothing to do with Sweden.

It wasn't until half an hour later that the staff who followed Pang Xuelin whispered in Pang Xuelin's ear: "Professor Pang, it's your turn." ”

Pang Xuelin nodded with a smile, and followed the Swedish female college student leading in front of him into the main venue of the concert hall.

The decoration style in the main venue is mainly solemn and elegant, and a bronze bust of Nobel is placed under the white curtain in the middle of the stage.

Ten flower baskets are placed on the stage, and in the flower baskets are gladiolus and lilies.

In the sound of music, Pang Xuelin walked into the center of the podium.

A message from Lars Hykentens, President of the Nobel Foundation, rang in my ears: "Since the invention of the voltaic battery in 1800, for more than 200 years, from lead-acid batteries, to lithium batteries, to fuel-air batteries, we have always been committed to improving the energy storage density of batteries. Especially in recent years, with the increasing scarcity of chemical resources such as oil and coal, as well as the increasing environmental pollution, the development of new green energy has become a top priority for the development of human society. Lithium-air batteries are known for their high energy density and long cycle life. The advantages of green and pollution-free have become the focus of attention of scientists around the world. And a major breakthrough in this field is officially from China's Mr. Pang Xuelin. He is one of the youngest Nobel laureates in history, and his achievements, from mathematics to materials science to electrochemistry, have pointed the way for the development of human society. His achievements in the field of graphene and lithium-air batteries have led us from the oil age to a more environmentally friendly and green future. This year's Nobel Laureate in Chemistry, Professor Pang Xuelin! ”

Lars Hykentens's words fell, and the audience burst into applause.

Pang Xuelin slowly walked up to the stage and came to King Gustav of Sweden.

"Hello, Your Majesty."

Pang Xuelin bowed slightly and smiled.

Gustav smiled and said, "Hello, Professor Pang. You are the youngest of the winners I have ever met, and I hope to see you again on this stage in the future. ”

"Your Majesty thinks I can win the award again?"

Pang Xuelin's face showed a look of surprise.

Gustav smiled: "Why not? Young man, I have read your information, you are the most gifted and incredible scholar I have ever met, but it is a pity that the Nobel Prize in mathematics is not awarded, otherwise you should have won the prize a long time ago. Of course, we also have the Physics Prize and the Physiology Prize, and I look forward to seeing you again here. ”

"Thank you!"

Pang Xuelin received the gold medal and certificate from Gustav, shook hands with a smile, and then took a group photo with reporters.

The award ceremony lasted until 5:30 p.m., after which Pang Xuelin followed the other laureates to Stockholm City Hall for a Nobel Prize dinner.

More than 1,300 guests attended the dinner, and the organizers arranged Pang Xuelin's parents, grandparents, Qi Xin, Yao Bingxia, and Zuo Yiqiu at a table very intimately.

Before the official start of the dinner, the ten winners also need to give speeches on stage.

At a quarter past six o'clock in the evening, Pang Xuelin slowly walked onto the podium amid warm applause at the scene.

"Honorable Mr. President, Distinguished Laureates, Ladies and Gentlemen,

It is a great honour for me to be here with you today.

Before I make my report, I would like to thank the Nobel Prize Jury, the Nobel Prize Foundation, for awarding me the 2021 Nobel Prize in Chemistry. This is not only a personal honor for me, but also a reward and encouragement for my research team.

Regarding the R&D process of lithium-air batteries, you may have seen in many reports. I'm just going to give you a quick run.

In 2020, when I was traveling to the United States to give a lecture, I met Professor Kirton Walker in Princeton.

At that time, Professor Corton Walker was in a difficult situation, but I was deeply moved by his dedication and pursuit of lithium-air batteries.

Because of this, I agreed to work with Professor Kirton Walker to establish an experimental team at Jiang University and find a path to success.

In this team, in addition to Professor Cotton Walker and me, there are also Professor Ye Xingmin, Professor Huo Ziqian, Professor He Wenyan, Professor Qiu Qiwei, Professor Xu Ting, and many other colleagues who have worked this project.

I am very proud of them, and it is because of their tireless efforts that we have been able to complete the breakthrough of lithium-air batteries in such a short period of time.

Lithium-air battery, more accurately called lithium-oxygen battery (Li-O2), is a battery based on the conversion of metal into air chemical energy for electrical energy.

The theoretical energy storage density of this battery is so high that it has been considered the ultimate energy source in the battery world.

But in the eyes of many knowledgeable people, there are many insurmountable obstacles in lithium-air batteries.

For example, how to prevent chronic leakage of diaphragms with two electrolytes?

How can I increase the usable temperature of the organic electrolyte?

How do I find an alternative to the gold and platinum catalysts currently in use?

How can I prevent an explosion caused by water vapor ingress when replacing lithium fuel?

How do you recycle unused lithium and lithium hydroxide?

how to reduce the energy consumption of circulating lithium hydroxide and so on.

So many big holes that when I announced the development of a lithium-air battery, many people thought the project was a pure gimmick. ”

Pang Xuelin paused, and there was a burst of laughter at the scene.

After all, because of the lithium-air battery project, Pang Xuelin's bet with people has long been spread all over the world.

Everyone understood what he meant.

Pang Xuelin smiled and continued: "But in the end, I proved that this is not a gimmick. Because of this experience, I hope that the academic community can build on the more relaxed atmosphere of some of our young scientists.

Truly interesting scientific research is driven by curiosity, sometimes leading to new breakthroughs in unexpected areas.

Some discoveries, even if they don't really solve the problem, can give us a better understanding of the universe, nature, society, and ourselves.

Just like Dr. Wilson, known as the king of accelerators, when he and his mentor Lawrence built cyclotrons in the thirties, no one knew what this thing could bring us.

But in the end, his accelerator became an important part of Fermilab, not only played a vital role in the research of nuclear bombs, but also in the later research of physics, almost all the progress in the field of basic physics came from the progress of accelerator technology.

At the same time, as a young scientist, I would like to give some advice to the academic community.

The quality of scientific research in the future depends on the efforts of our young scientists, we need higher quality talents, so that young scientists can devote themselves to research without any worries, so that young students are interested in scientific research and willing to become scientists, I hope that academic research is not only rigorous and, but also interesting and imaginative. I also hope that some of the achievements of Nobel laureates will pique some interest among young scientists and inspire them to devote more time and energy to the field of science.

Here, I would like to thank all my colleagues, colleagues and friends at home and abroad who have contributed to the research and development of lithium-air batteries.

I am deeply grateful to my family for their continued understanding and support!

Thank you very much for joining us!

Thank you! ”
