Before the birth of graphene, graphite, as a two-dimensional carbon material, has always been a popular research object among scientists from all walks of life. (Free download of full text e-book)

The reason why scientists like it so much is because of its special internal molecular structure, which is a lamellar honeycomb structure.

Graphene has always been assumed to be the single-layer structure of graphite. It is a flat film composed of carbon atoms with sp2 hybrid orbitals forming a hexagonal honeycomb lattice. It is a two-dimensional material with only one carbon atom thickness. However,

Because of the problem of structural stability, it cannot exist alone.

In 2004, at the University of Manchester in the UK, two physical scientists from the former Soviet Union, Andre Hymer and Konstantin Novoselov, conducted an experiment. The main purpose of this experiment was to

To obtain graphene, it is necessary to verify that graphene can be independent of graphite and exist as an individual.

The two found a graphite sheet, then stuck a special tape on both sides of the graphite sheet, and then pulled it hard to separate the graphite sheet. Then they used the same method to process it, and continued to stick the tape on and pull it apart.

, until finally a layer of graphite flakes with only one layer of carbon atoms was obtained, which is graphene.

After the birth of this material, it immediately caused a shock in the entire scientific community. However, currently, this material has not been widely disclosed to the outside world, so it is natural that Binxinwei does not know about the birth of this material.

The emergence of graphene caused huge waves in the scientific community. It was discovered that graphene has extraordinary conductive properties, is dozens of times stronger than steel, and has excellent light transmittance.

Its emergence is expected to trigger a revolution in the field of modern electronic technology. In graphene, electrons can migrate extremely efficiently, while traditional semiconductors and conductors, such as silicon and copper, perform far less well than graphene.

And when electrons propagate in silicon or copper, due to the collision of electrons and atoms, traditional semiconductors and conductors release some energy in the form of heat. Currently, general computer chips waste 70%-80% of their energy in this way.

Electric energy, graphene is different, its electron energy will not be lost, which gives it unusual and excellent properties.

His emergence was an epoch-making revolution in the field of materials science. In the following years, it was widely used in the preparation of nanoelectronic components, supercomputer chips and photonic sensors. (Full text e-book for free.

In 2010, Andrei Heimer and Konstantin Novoselov, a pair of master and apprentice scientists, won the Nobel Prize in Physics that year precisely because of their discovery of graphene.

Of course, it's only 2005 now, and this material has only been around for a few months. The master and apprentice pair above are still thinking about how to confirm that this thing is graphene, and how to prepare it in large quantities.

What a process.

Jin Xiaoqiang's mention of this material to Binxinwei at this time was completely nonsense. In later generations, it was true that Americans used this material to create a super lithium battery, but that had to wait until after 2010.

Right now, Americans may have only just become aware of this material.

Jin Xiaoqiang nonsensically explained to Binxin WeChat about the invention of the material graphene by Andrei Hemmer and Konstantin Novoselov.

As a scientist who has been dealing with lithium batteries and graphite for a long time, Binxinwei had heard of graphene when he came into contact with graphite. However, at that time, this material had always existed and been a myth, not in the

Materials that exist in reality.

Now after Jin Xiaoqiang told him this, he realized that the legendary magical weapon had actually been invented by his British colleague.

Is this good enough?

When Binxin heard Jin Xiaoqiang's explanation, he immediately became confused. He had no doubt that the fact that Jin Xiaoqiang could get such news out of an American scientist within a few meals was true or false.

In his opinion, since graphene exists and can be prepared in this way, what are you waiting for? Let’s study this stuff quickly!

Hurry up and get this thing out, and then use it on our lithium batteries. Then our lithium batteries can also become miracles?

But how did he know that if you want to make such graphene, it is not such a simple project. The two brothers who discovered graphene have not yet been able to solve a large number of methods for preparing graphene.

In later generations, this material was once named black gold, and its price was once speculated to ten times that of gold, reaching the highest level of 2,000 US dollars per gram.

Later, after scientists' research and the invention of several large-scale processes and methods for preparing this material, the price of this material gradually dropped.

It was not until that time that Americans dared to apply this material to lithium batteries in large quantities, but it was also an expensive military product. As for civilian products, it would still take ten or eight years.

Ohio-based nanotec in the United States, the aforementioned nano that cooperates with the US military, is the first company to apply this material to lithium batteries.

The super lithium battery they invented was first used in American unmanned reconnaissance aircraft, and the best thing about this lithium battery is that it only takes one minute to charge!!!

That’s right! It only takes one minute. While other Japanese shortened the charging time of their lithium batteries to seven or eight hours to be fully charged, Americans have been able to make super lithium batteries that can be fully charged in just one minute.

.

This kind of super lithium battery takes advantage of the super good conductivity of graphene, and its capacitance and power are a hundred times higher than ordinary lithium batteries, reaching 100 kilowatts per kilogram.

If it is applied to pure electric vehicles, then an electric vehicle that is fully charged in one minute can run hundreds of kilometers. When this kind of battery can be widely used, let alone hybrid vehicles, it will be a pure electric vehicle.

It’s no longer a dream!

But now if you want to prepare large amounts of graphene and use graphene to make super lithium batteries, there are still many problems that need to be overcome.

One is the preparation of graphene. After all, even the two masters and apprentices, Andre Heimer and Konstantin Novoselov, who discovered this material, have not figured out how to prepare this material in large quantities.

The second is how to apply this kind of material to various subjects in large quantities. After all, the fields this kind of material involves involves all aspects.

Nanoelectronic components, optical components, lithium batteries, etc., this material can be applied in all fields.

Binxinwei couldn't stay any longer at this time, and even immediately wanted to rush into the laboratory and prepare a piece of graphene according to the method Jin Xiaoqiang said to see if this material existed.

But Jin Xiaoqiang has no intention of leaving yet. He has only visited half of the battery laboratory, and there are still many things he has not finished!

Bin Xinwei was already in a state of disbelief at this time, and Jin Xiaoqiang had to call him several times to summon him out of his soul. Only then did he call him back from his lost state.

"Haha, Engineer Bin, don't worry. After I finish visiting the laboratory, you can start studying this graphene immediately. You have plenty of time!"

Jin Xiaoqiang said to Binxinwei with a smile, but Binxinwei seemed to have lost his soul, as if he didn't listen at all to what Jin Xiaoqiang just said.

Seeing that Jin Xiaoqiang still had no intention of leaving, Binxinwei could only scold Jin Xiaoqiang in his heart for being ignorant, and accompanied Jin Xiaoqiang to inspect the place.

But he quickly adjusted his mentality. Jin Xiaoqiang shocked him too much today. Could it be that this guy really managed to get such an idea out of the mouth of that American scientist with just a few meals?

Something useful?

Also, this guy’s understanding of lithium batteries doesn’t seem to be any weaker than that of a professional like himself?

Does he really know nothing? Or is he pretending to be a pig and eating the tiger?

The two tips he just gave him were more shocking than the last. Anyone who is engaged in lithium battery research and development would probably be shocked by the information provided by this guy after hearing such news.

light.

Could it be that all the information this guy provided was something he thought of or obtained accidentally?

In this case, it is inevitably too coincidental, right?

But if Mr. Jin is really that kind of hermit expert and really understands lithium batteries, this is a bit unreasonable. If he really understands, then he can completely produce these lithium batteries by himself?

Why spend so much effort to hire people like yourself and organize such a large team? You must know that this team will spend hundreds of thousands of dollars to conduct experiments every day, plus such a large team.

Gangzi people, people eat horse chews, and their monthly expenses are no less than hundreds of thousands.

Is he really willing to throw the money into the water and just listen to the sound?

Bin Xinwei couldn't help but be confused by Jin Xiaoqiang's pretense of profoundness. At this time, in his opinion, Mr. Jin was an unpredictable and profound master. He was really a master!

The title of genius on his head is really not for nothing, his brain is really good.

After a while of guessing on Binxin WeChat, Mr. Jin is a genius who doesn't understand lithium batteries. This is also thanks to the fact that he is engaged in automobile research and development. If he came to engage in lithium battery research and development, people like him would probably...

I'm afraid there's no place to eat for a long time.

Jin Xiaoqiang didn't know what Binxinwei was thinking. At this time, he was thinking about how to continue to mention Binxinwei. There were still several key ideas in his mind!
