Hand rubbing nuclear fusion live in the wilderness

Chapter 252 Various approaches to solve the problem of lithium dendrite growth
After several trips back and forth, Han Yuan moved all the materials and equipment needed to prepare lithium-sulfur batteries to a dust-free studio.

This is a class [-] dust-free workshop. It's not very good, but it's not bad. It's just that the area is not big, less than twenty square meters.

However, there are still supporting facilities such as air conditioning, heat insulation, ventilation systems and other equipment, which are sufficient for the laboratory to prepare materials related to lithium-sulfur batteries.

After all, it's just a battery, not something like a chip or an optical microscope that needs to be processed in a high-dust clean and constant temperature workshop.

After sorting out the materials and equipment brought over, Han Yuan pulled the camera over and took pictures of the lithium, sulfur, zirconium and other materials and all the materials and equipment on the silver-white experimental table, and then said:
"These materials on the table are what are needed to prepare high-energy storage lithium batteries."

"And the lithium battery I made this time is a type of lithium-sulfur battery -- 'sulfur-carbon composite lithium battery'."

Hearing this, many viewers in the live broadcast room were a little surprised.

[Lithium-sulfur battery? 】

[Let's start quickly, I can't understand it anyway, just talk about how amazing the result is. 】

[I thought it was a lithium-air battery, but it turned out to be a lithium-sulfur battery. 】

[Why does it feel so low, making lithium-air batteries, the anchor, that one is tall! 】

[Why, the one upstairs looks down on lithium-sulfur batteries?This thing is also black technology, and it only exists in the laboratory. 】

[It is said that after the anchor is created, we should be able to use it, right? 】

[It is estimated that it will be everywhere on Taobao in a few days. 】

[It should be able to be used, but it depends on the importance and whether it is awesome. If it is awesome, what the manufacturer sells to us is definitely inferior or even inferior. 】

[Indeed, capitalists are best at doing this kind of thing. 】

[In other words, I remember that lithium-sulfur batteries seem to have many problems that have not been solved, the most difficult of which is the problem of lithium dendrite growth. Could it be that the anchor has solved it? 】

[I am a doctoral student majoring in inorganic chemistry at Tori University, and I am writing my graduation thesis. The direction is lithium-sulfur batteries. If the anchor makes lithium-sulfur batteries, I am afraid that I will graduate a year or two later. 】

【Ah, (⊙o⊙)..., the upstairs is really miserable. It seems that your postponement of graduation is destined, but why do I want to laugh.】

[Hahahahaha, what kind of unlucky guy is this?Like agricultural students?Is it the same as being eaten by a cow and failing to graduate? 】

On the virtual screen, there was a lot of discussion on the barrage, and a large part of the audience was even a little disappointed in the lithium-sulfur battery that Han Yuan said.

Without him, the force was too high when making electric propulsion-free engines. Now these people look down on lithium-sulfur batteries and think that lithium-air batteries are what should appear.

Compared with ordinary audiences, relevant experts in laboratories in various countries were much more excited.

While not a lithium-air battery, a lithium-sulfur battery is more in line with practical goals.

In the past 20 years, the research and development teams of laboratories in various countries have basically shifted their attention from lithium-air batteries to lithium-sulfur batteries, because lithium-air batteries are basically a pie separated by tempered glass.

You can see it, but you can't touch it, and you can't eat it.

Lithium-sulfur batteries are different. Most of the technological difficulties of lithium-sulfur batteries have been overcome. They belong to the kind of big pie separated by a thin film, which can be touched by hand.

It's just that this layer of film is a bit too tough, and I don't know how long it will take to pierce it.

But now it seems that it will soon enter the new world and give birth to the next generation.

In order to manufacture a real lithium-sulfur battery, it is necessary to solve the problem of lithium dendrite growth. In addition, it is necessary to solve the problem of sulfur being non-conductive.

However, the problem of lithium dendrite growth does not only exist in lithium-sulfur batteries, even lithium-air batteries separated by tempered glass also have this problem.

Lithium-air batteries also look promising if the problem of lithium dendrite growth can be solved.

If the growth problem of lithium dendrites can be solved smoothly, there is no doubt that whether it comes from the country or from capital, large sums of money will pour into the field of batteries.

Even if there may be some unlucky laboratories that happen to be researching lithium anode materials, funding or the entire project will be cut off because of this.

But definitely more funding and more R&D projects would make them happy.

The most representative of this event is the stock market.

The stock market has always been the traffic light and barometer of the economy.

Just like when Nasdaq opened today, technology companies related to the power energy module and battery industry are green and rising very rapidly.

Correspondingly, the decline in traditional energy and fuel vehicle modules.

Everyone knows that if this anchor can successfully develop a lithium-sulfur battery with high energy storage, I am afraid that it will not be long before there will be electric vehicles everywhere in the streets and alleys of the world.

A high energy storage lithium battery that can support the huge power consumption demand of the electric propulsion engine.

No one knows how terrifying its energy storage is until the specific data comes out.

But everyone knows that the end of fuel vehicles may be coming.

Seeing the bullet screens on the virtual screen that may delay graduation because of himself, Han Yuan couldn't help but smile. This is really a sad thing.

"The growth of lithium dendrites is indeed a very troublesome problem."

"But since it is a problem, there is always a solution."

"The solution to the growth problem of lithium dendrites is generally divided into two types, one is inhibition, and the other is guidance."

"Inhibiting the growth of lithium dendrites is a common method to solve the problem of lithium dendrite growth."

"There are also two commonly used suppression methods, one is artificial SEI film to inhibit dendrite growth, and the other is stable lithium deposition method."

"And this time I used the method of 'manufacturing SEI film' to suppress the growth of cathode lithium dendrites."

While explaining, Won started to act.

"When it comes to artificially manufacturing SEI films, it must be mentioned that the SEI film born by the lithium-sulfur battery itself."

"It is well known that lithium metal is considered one of the most ideal candidates for battery technology due to its extremely high theoretical capacity."

"Unfortunately, the highly reactive lithium metal will react with any organic electrolyte to form a fragile and inhomogeneous solid-state electrolyte phase film, also known as the SEI film."

"Instead, the self-generated heterogeneous SEI composition on the Li metal surface leads to the uneven distribution of Li-ion flux, which simultaneously leads to uneven Li plating, stripping behavior, and severe Li dendrite growth."

"So artificially manufacturing a layer of SEI film to replace the self-generated SEI film of lithium-sulfur batteries is a very effective way to inhibit the growth of lithium dendrites."

"The protagonist this time is a solid artificial solid electrolyte mesophase film with 'bionic ion channels' and 'high stability'."

"Its main component is a macromolecular metal skeleton compounded with perchlorate ions."

"The material is called a 'metal-organic framework material.'"

"Of course, there are many different types of metal-organic framework materials, and the one I made today is based on the metal 'zirconium' as the framework."

"It is a three-dimensional macromolecular macrovoid material with excellent single conductivity and mechanical strength, while the complex perchlorate ion has quite excellent thiophilicity."

"The combination of the two can satisfy both electrical conductivity and sulfur affinity, and can replace the original SEI film after covering."

A series of various professional terms came out of Han Yuan's mouth, and most of the audience in the live broadcast room were stunned when they heard it, and everyone was dumbfounded.

[What did the anchor just say? 】

[It's over, I can't understand again and again. 】

[I don't understand the same, but I probably know that Dong Li's top student may really delay his graduation. 】

[Artificially manufactured SEI film!Metal Organic Framework Materials!I'm really going to cry, the host is serious, I still want to graduate this year. 】

[Good guy, I remember that the growth of lithium dendrites is a worldwide problem, right?I didn't expect it to be so worthless here as an anchor, and it seemed like he had many solutions. 】

[Upstairs really didn't say it, just said two before the general direction, one is restraint, and the other is guidance, right? 】

[That's right, there are two types of suppression, the artificial SEI film and the stable lithium deposition method. In addition, there are classifications below, which are absolutely amazing. 】

[It is confirmed that the anchor is definitely an alien! 】

[Maybe it's a Huaguo person from a parallel world, or maybe it's a person from a future time and space. 】

A lot of nouns were thrown over, and the ordinary people in the live broadcast room were stunned in an instant.

But it made experts from all over the world and research and development personnel in laboratories extremely excited, even trembling with excitement.

Because the more detailed Han Yuan said, the more confident he is that he can really solve the problem of lithium dendrite growth and manufacture lithium-sulfur batteries.

Especially some of the ways he mentioned to solve the problem of lithium dendrite growth.

Inhibition and guidance.

Artificial SEI films and stable lithium deposition.

Macromolecular metal skeleton compound perchlorate ion.

These things are the most important knowledge and information that no scientific research scholar or expert in the corresponding field will let go.

Although there are no detailed manufacturing steps and principles, it just points out a direction for them.

But scientific research often lacks a direction.

You must know that humans have tried countless methods to solve the growth problem of lithium dendrites.

From the uniform lithium ion flow method to the artificial SEI film to inhibit the growth of dendrites, I have tried it.

Behind these methods, there are countless funds, manpower, material resources and time.

If someone can accurately point out an effective method, the problem of lithium dendrite growth has long been solved by humans.

Don't underestimate the scientific research ability of human beings. With the assistance of countless funds and a huge population, as long as we confirm that this problem has a solution, it is a problem that can be solved in this century, and it points out the direction.

20 years at the latest, or even ten years, is enough, enough for human beings to develop it.

This is any human being's confidence in the wisdom of human beings, and no one will doubt it.
