Looking at Wen Yuanhang, who was rarely a little impatient, Xu Chuan smiled and took out a document from the drawer and handed it over.

"This is the latest achievement of lithium-sulfur batteries at the Chuanhai Materials Research Institute, you can take it back to professionals to see."

For Wen Yuanhang's anxious mentality, he actually understood.

Because although the battery is small, it is an important part of the national strategic development.

From people's livelihood, to national defense, from mobile phones and computers to aerospace, they are all inseparable from a small battery.

Wen Yuanhang quickly took the report document and flipped through it briefly.

In the test data for lithium-sulfur batteries, the battery energy density test information that he is most concerned about comes into view.

2117.24Wh/Kg！

With an energy density of up to more than 2,000 years, it can reach more than twice that of lithium-ion batteries currently on the market!

Of course, if it is a single energy density, this value is not a new record in lithium batteries today when the lithium dendrite problem has been solved.

In many laboratories in various countries, there are actually many different types of lithium battery products that are higher than this.

For example, the Argonne National Laboratory under the Ministry of Energy of the United States successfully developed and tested a new lithium-sulfur battery in the laboratory in the first half of this year, with an energy density of 2300Wh/kg.

Even the Sakura Country has come up with the legendary lithium-air battery, and the energy density in the laboratory is simply explosive to the traditional lithium battery.

But laboratory products are laboratory products after all, and they cannot be put on the table.

In the hands of those researchers, sometimes the research done in the laboratory is not necessarily commercial, but it may also be done to the limit, or something to earn fame or something.

Argonne National Laboratory's lithium-sulfur battery of up to 2300Wh/kg is what was piled up in the limit test of lithium batteries.

Aside from the fact that energy density is eye-catching, all other attributes can be said to be garbage.

Charging and discharging cycles, crotch pulling, sulfur compounds in the battery after use, blocking the electrolyte, automatic shutdown or even explosion in high and low temperature environments, etc.

Due to a series of defects, even with its extremely high energy density, it could not be officially launched for commercial production.

And batteries that can't be produced commercially don't make much sense.

But the report in his hands is completely different.

The lithium-sulfur battery researched by the Chuanhai Materials Research Institute does not have a simple energy density of 2,000, but something that can be really practical and commercialized.

All kinds of low temperature, high temperature, vibration, impact, limit test and other lithium battery test steps and test content have been completed, from the experimental data, not to say very good, but absolutely above the standard line.

Such a lithium-sulfur battery, just waiting for the announcement, can set off a violent earthquake in the current battery industry.

Briefly flipped through the report in his hand, Wen Yuanhang looked at Xu Chuan, couldn't suppress the excitement in his heart, and said admiringly: "It is worthy of Academician Xu, once again leading the world!" ”

Xu Chuan shook his head and said, "The research results this time have little to do with me, but they are the credit of the Chuanhai Materials Research Institute. ”

Wen Yuanhang smiled, and did not dwell on this.

Xu Chuan said that it was the credit of the Chuanhai Materials Research Institute, that is, it was okay, anyway, the research institute was his.

At the national level, no matter who developed the lithium-sulfur battery, as long as it is in China, it is completely good.

On the basis of Huaguo's first realization of controllable nuclear fusion technology, batteries determine their deployment and control progress in the field of new energy around the world, especially in the field of new energy vehicles.

China's strength in the automotive field, like the traditional aerospace field, can be said to lag far behind those Western countries.

For a long time in the past, joint venture cars were more trusted by ordinary people.

As for domestic production? I have to say, what kind of garbage is that?

Even in 23 years, the development speed of domestic cars is quite fast, and this concept is still quite strong in China.

On the one hand, almost all of the top luxury brand cars are foreign cars, and on the other hand, the domestic automotive industry is indeed 'crotch-pulling'.

Not to mention the traditional fuel vehicles, the development is indeed lagging behind others for decades, and it is indeed very difficult to catch up with the situation that Western countries have established their own channels and reputation.

But new energy

A few years ago, for many little-known car manufacturers, this thing was purely a thing used to cheat insurance.

The ecological environment in China was once so rotten that it could not be seen at the highest level.

But fortunately, with the introduction of Tesla and a series of policy changes, there are still a number of new energy vehicle companies that have successfully come out of the rotten environment.

However, it is still quite difficult to go global and occupy a place in terms of sales and influence.

Especially in the layout of high-end luxury brands, it is even more difficult to break through the siege.

Lithium-sulfur batteries may be this opportunity.

At the same time, the other side.

Illinois is located at Argonne National Laboratory, surrounded by the Chicago Forest Preserve.

Professor Teresa Achille, who was sorting through the experimental data in her office, was humming a ditty, happily replying to and processing email after email.

In 1942, Nobel laureate Fermi led the construction of mankind's first controllable nuclear fission reactor (Chicago 1), an important part of the Manhattan Project and ushered mankind into the age of atomic energy.

After the Second World War, Argonne laboratories were tasked with developing a peaceful use of atomic reactors. Over the decades, the lab's research has expanded to include many other areas of science, engineering, and technology.

Professor Theresa Achille is leading the 'Battery Project', which is part of the most important energy program in the Argonne laboratory.

Just about two months ago, an experimental group in the lithium-ion battery project he led made a major breakthrough in the field of lithium-sulfur batteries.

While working on lithium-sulfur batteries, the team discovered that an allotropic form of sulfur has the ability to stabilize the 'shuttle effect'.

In subsequent research, it was found that the risk of polysulfide formation in lithium-sulfur batteries could be further eliminated by using different materials.

The best auxiliary material for this is carbon nanomaterials, and through continuous experiments, they have determined that the shuttle effect of lithium-sulfur batteries and the risk of damage to the battery by polysulfides can be solved to a certain extent by the assistance of high-purity carbon nanotube materials.

Judging from the current experimental progress, it is estimated that in a period of time, they will be able to complete this 'brilliant' project and develop the latest generation of lithium-sulfur batteries.

The high energy density of lithium-sulfur batteries can undoubtedly completely crush all lithium-ion batteries on the market.

Thinking of this, the corners of Theresa Archer's mouth couldn't help but raise a smile.

Batteries are a trillion-dollar market, and if they can monopolize this market, the huge benefits they can bring are unimaginable.

He had seen a lot of money and fame beckoning to him.

Even if the results belong to the laboratory, as the leader of the 'battery project', his credit will not be lost.

Even, after solving the shuttle effect of lithium-sulfur batteries, it is not impossible for him to win the Nobel Prize in Chemistry.

After all, in recent years, there have not been many real achievements in the field of chemistry, and most of the medals have been awarded to the field of biochemistry.

The shuttle effect of lithium-sulfur batteries is undoubtedly an extremely important real chemical problem.

I believe that the Nobel Royal Jury will definitely put this achievement into the nomination.

Just as he was dreaming of a better life in the future, the sound of hurried footsteps outside the office came.

Immediately, after a few knocks on the door, a bespectacled white female assistant barged in without waiting for Theresa Achille to open her mouth, holding a paper in her hand.

Looking at the assistant who broke in, Theresa Achille, who was in a good mood, didn't mind this kind of behavior, and asked with a smile, "Kelly, is there something wrong?" In such a hurry, you have to be careful of falling. ”

"Director Theresa, things are not going well."

With a hint of anxiety on her face, Kelly Vicky quickly handed over the document in her hand, and continued without taking a breath: "Huaguo is suspected to have made a major breakthrough in the field of lithium-sulfur batteries!" ”

Hearing this, Theresa Achill was stunned for a moment, then smiled and didn't pay much attention to it.

"Huaguo? What breakthroughs can they make with lithium-sulfur batteries? The artificial SEI thin film technology developed by Professor Xu did not allow them to grasp this huge market. ”

It's not that he looks down on Huaguo, but it's a real thing.

In the case that the core technology of artificial SEI thin film technology leads the world, Huaguo has not been able to control the lithium battery market. Now they have caught up in an all-round way, and even the capacity of many batteries has surpassed each other, occupying a large part of the market.

Assistant Kelly Vicky on the other side quickly replied: "But this breakthrough has something to do with Professor Xu Chuan, and it is made public by the Chuanhai Materials Research Institute under his name, that is, the laboratory that developed artificial SEI thin films." ”

Hearing this, Theresa Achill was stunned for a moment, then frowned slightly, and quickly took the paper from the assistant's hand.

The shadow of the famous tree, the name Xu Chuan has been too loud in recent years.

Even if he looked down on Hua Guo's scientific research ability, he couldn't ignore that Professor Xu.

What's more, the artificial SEI film was originally developed by him, and if there is a breakthrough in lithium-sulfur batteries, it may really be possible.

Picking up the journal Science from his assistant, Professor Theresa Achille opened the paper.

Immediately, the title of the paper caught his eye, and his pupils suddenly contracted.

"'Monoclinic gamma phase sulfur', the end of the 'sulfur' problem of lithium-sulfur batteries! 》

"Damn, don't be the shuttle effect of our research!"

After the title came into view, Theresa Archer's heart suddenly burst into it, and she gritted her teeth and quickly flipped through it.

As the pages of the paper entered his pupils, the data of one item after another crossed his eyes, and after seeing the conclusions and experimental data of the last few pages, he angrily smashed the coffee cup in his hand against the white wall of the office.

With a crisp bang, the glass slammed into the wall and shattered into countless pieces of glass, and the dark brown coffee suddenly stained a brown map on the white wall.

The assistant on the side stood beside him with his head down, not daring to come out, for fear that he would attract the attention of Professor Achill.

As an assistant, she is well aware of the recent breakthrough in lithium-sulfur batteries and the consequences of this paper.

It can be said that as soon as this paper came out, all their previous research was scrapped.

Looking at the coffee spilled on the wall, Professor Theresa Achille, who is in charge of lithium-sulfur battery research at the Institute for Energy and Global Security, forced herself to calm down.

Suppressing the anger in his heart, he said coldly to his assistant: "Check! Damn it! I wonder who leaked the lab's secrets! ”

There are many people who pay attention to Xu Chuan's movements, from himself to the research institute under his name, whether it is Xinghai Research Institute, Chuanhai Materials Research Institute, or that network technology company, they are basically in the scope of monitoring in various countries.

After the information related to lithium-sulfur batteries appeared, countries naturally paid attention to the relevant information in the first time.

As a national laboratory under the United States, Argonne National Laboratory is no exception.

But after getting the paper, Professor Theresa Achille, who is in charge of lithium-sulfur battery research at the Institute for Energy and Global Security, was extremely angry.

"The end of the 'monoclinic gamma phase sulfur' lithium sulfur battery 'sulfur' problem! 》

One paper is almost the same as their research direction, both of which are allotropic forms of sulfur 'monoclinic gamma sulfur', and even further directions are to use carbon materials to stabilize 'monoclinic gamma sulfur'.

The only difference is that Argonne National Laboratory uses carbon nanotube materials, while their rival, the Chuanhai Materials Research Company, uses graphite that they have studied and discarded.

It's hard not to suspect that someone in the lab leaked data from previous studies.

After all, judging from the paper, the research direction and ideas are no longer generally similar.

Although no one has stipulated that two different research institutes cannot have the same research method, it is extremely rare for a coincidence to be so high.

"What are you still doing here, why don't you go and investigate?!"

Seeing his assistant standing there in a daze, Professor Theresa Archer was angry again, and scolded angrily.

"I'll go."

Hearing the second time, the assistant reacted, answered in a panic and ran out quickly.

Theresa Achill glanced at her assistant's back, sat back behind her desk with a gloomy face, picked up the landline phone, and dialed a number to go out. After a few brief words, he ended the call, his eyes falling back on the paper on his desk.

In the field of materials, if a competitor is the first to take the lead in a certain research direction, it means that all the other people's research is scrapped.

The market is so cruel.

Especially in the field of batteries, although they are also very promising to solve the shuttle effect of lithium-sulfur batteries, when faced with a product in the laboratory and a mature technology, you can know with your toes how to choose.

"Damn it! It's not over! ”

Looking at the eye-catching title on the paper, Theresa Archie gritted her teeth and was very unwilling.

He must report it to Congress!

Argonne National Laboratory can't just be lost in vain!

Also, don't let him find out who leaked the lab's research data, or he'll send him to the prison in St. Quentin!
