Let You Build A Fuel-Efficient Car, You Build A Super Electric Car?

Chapter 97: The First Graphene Battery Goes Offline! ! !

And several other joint venture car companies.

In communication with Panasonic Group.

Almost got the same response.

no way.

They have all been commanded.

None of these car companies listened.

In order to seize the market.

so crazy!!

And the people in charge of these car companies feel as if they have eaten tower flies.

But also had to return the car immediately.

Fortunately, there are not many vehicles off the assembly line at present.

Making a recall is relatively easy.

But the stocks of these car companies.

But I couldn't bear it anymore.

It was previously announced that it wanted to seize the market of Longguo and carry out new energy transformation.

Being optimistic about the capital, the stock has been rising.

And now.

Immediately ushered in a round of plunge!!

Just this drop.

It has already caused several major car companies to lose more than one billion yuan!!

Other onlookers car companies.

shivering...

Good guy.

Fortunately, the first batch of battery packs rolled off the assembly line by Panasonic Group was not many, and they failed to keep up.

Otherwise, they are the ones who are losing so much now.

A car company that had the opportunity to cooperate with Kunlun before.

I am so regretful that my intestines are green!!

"Damn it, I didn't expect the gap between the battery pack developed by the top international group and Kunlun to be so big..."

"Whether it is energy density or safety, there is a huge difference!!"

"Kunlun is the most professional in making battery packs!!"

"I regret it, I would have contacted Kunlun if I knew about it earlier!!"

"Cheap is not good. It's only one or two hundred cheaper than Kunlun, but it creates such a big safety hazard..."

The heads of these car companies.

Finally understood.

The gap between them is too big.

can now.

It's too late to regret.

People in Kunlun don't care about them anymore.

at this time.

Li Ming didn't know the news from the outside world at all.

He is in Kunlun's battery factory, excitedly researching the graphene centrifugal extractor.

Research and development work has been carried out to the final stage.

Operate the mechanical arm.

There can be no sloppy.

This chemical extraction machine, after his transformation, has reached a level of precision and purification output that has never been achieved by top scientific research laboratories in the world.

To know.

The separation and extraction of graphene itself is very troublesome.

the earliest time.

Graphene was extracted by two European scientists through the "mechanical exfoliation method".

Of course.

This "mechanical peeling method", although it has the word "mechanical".

Don't think how efficient it is...

How advanced the technology is.

In fact it is—

The two European scientists used scotch tape to peel off layers of natural graphite, and finally obtained low-purity graphene.

And this method.

It was also once considered to be inefficient and unable to achieve mass production at all!!

Some years passed.

Scientists behind.

Invented the "oxidation exfoliation method" and "epitaxy method" respectively.

"Oxidation stripping method" is to oxidize natural graphite by using chemical reagents such as sulfuric acid and nitric acid and oxidants such as potassium permanganate and hydrogen peroxide to increase the distance between graphite layers and insert oxides between graphite layers. oxidised graphite.

Then the graphite oxide is solid-dried, and then peeled off through a complex high-temperature process to obtain graphene oxide.

And "orientation epigenetic method".

It uses the principle of the atomic structure of the growth substrate to "plant" graphene.

First let carbon atoms infiltrate ruthenium at 1150°C, and then cool to 850°C, a large number of carbon atoms absorbed before will float to the surface, and the single layer of carbon atoms in the shape of a lens will grow into a complete layer of graphene. can be extracted.

These methods are demanding processes.

As well as temperature or chemical requirements.

Destined to be a product of high purity graphene, it can only stay in the laboratory stage.

Because a whole set is extracted.

The cost and time are too high.

It's not that it can't be made.

It's the time it takes to create it.

with energy.

It's not proportional to the effort at all.

Cannot be mass-produced!!

The "High Purity Graphene Centrifugal Extractor" manufactured by Li Ming is improved through another advanced absorption principle in the world.

That is, "silicon carbide epitaxy".

In the high-temperature environment of ultra-high vacuum inside the device, the silicon atoms are sublimated and separated from the material, and the remaining carbon atoms are restructured through self-assembly to obtain graphene based on a silicon carbide substrate.

This method can obtain high-quality graphene.

and.

It is also the current scientific research industry believes that the only way to achieve mass production of graphene in the future.

To realize the "silicon carbide epitaxy method", the requirements for the equipment itself are extremely high.

Domestic silicon carbide epitaxial furnace.

Almost all rely on imports.

At present, it is only equipped in the top scientific research rooms.

In the process of extracting graphene, a silicon carbide epitaxy furnace must be used to create an ultra-high vacuum environment, and high temperature sublimation must be achieved to allow atoms to be restructured inside, with a highly stable gas flow field, pressure field control, and induction heating. A set of induction cavity design.

Li Ming spent tens of millions of dollars to purchase top-level silicon carbide epitaxy furnaces from abroad for modification.

It took a full week.

It was finally pushed to the end.

"It's finally done!!"

Li Ming breathed a sigh of relief.

On a slightly tired face, there is a trace of excitement!

Looking at the results in front of him, although it is said to be based on the transformation of the "Silicon Carbide Epitaxy Furnace", it has actually been transformed into a fully enclosed sci-fi product by him.

It occupies a full five or six square meters.

In addition to the external buttons, write the number screen.

The formation of the inner vacuum environment is almost invisible.

With this "high-purity graphene centrifugal extraction machine".

By investing in natural graphite, large-scale mass production of graphene can be realized.

"Although the cost of graphene batteries cannot be as low as that of lithium batteries, all this is worthwhile.

Li Ming murmured.

The price of graphite is not expensive though.

However, the cost of a piece of graphene of the same volume is probably tens of thousands higher than that of a ternary lithium battery.

certainly.

Compared with the same period of time, the energy density has been increased by three times.

This news will definitely make scientists who study batteries and energy go crazy!!

this cost.

Relatively unable to mass-produce now.

The graphene extraction method that can only be manually operated by the machine.

It is simply a dimensionality reduction blow!!

And at this time.

Li Ming's cell phone rang.

"Boss, the graphene battery pack structure you asked us to develop has been developed, and the ratio of relevant materials and punching machines are ready..."

Chen Zhou called.

Just the other day.

Li Ming established a research and development plan for graphene batteries internally.

Then the technical principle document was given, and Chen Zhou was asked to lead the battery research and development department to develop the graphene battery pack.

This directly stunned the inside!!

Because Kunlun's battery department has gone out independently.

R&D personnel in charge of battery development.

The original battery pack architecture has been developed for different models.

for example.

The battery pack of a pure electric heavy truck has a different structure from the battery pack of a flagship car.

It needs to be redesigned and optimized based on principles.

In order to use the volume to the extreme.

They also thought about breaking through.

For example, make the energy density more concentrated.

However, the current characteristics of lithium batteries have almost been studied to the end.

This is a problem that top scientists cannot solve at present.

Their research wants to increase the energy density, and the natural progress is very small.

did not expect.

The boss directly sent a set of schematic drawings of "high-purity graphene battery"!!

#7*...

What is this for??

Is the boss crazy enough to use graphene to make batteries??

But isn't the cost a bit too much?

Looking at the complex principle on the battery pack, the high-purity graphene needed to make the battery is obviously not the garbage of those graphene mixtures out there.

It is the real "graphene battery" announced by top foreign scientific research laboratories at the beginning!!

The cost of the battery alone will cost millions.

Because high-purity graphene is too difficult to extract.

Boss, is it possible that he wants to build another supercar??

they feel.

Only supercars are equipped with such a luxurious battery.

Li Ming heard that the project of graphene battery pack architecture has also been developed.

Can't help but smile slightly.

The timing was just right.

This means that graphene batteries are now ready for immediate production!!

"In this case, you all come over and prepare for further production work."

Li Ming said.

As soon as this word came out.

Chen Zhou was shocked.

Production now??

Is the extraction of high-purity graphene in time??

But he still didn't say anything.

Since the boss said so, he naturally has his arrangements.

He directly brought the core R&D personnel of the battery department to the battery factory.

Waited until the inside of the factory.

They were stunned.

Chen Zhou took a look and found that the huge fully sealed vacuum equipment seemed to have a structure similar to an epitaxy furnace inside.

"Boss, what is this?"

Chen Zhou was startled.

Never seen such a complex epitaxy furnace.

Moreover, this equipment seems to not only play the role of an epitaxy furnace.....

Everyone was also stunned!

what is this?

It looks so hanging!!

Even if it's all closed.

Some of the advanced precision structures inside can be seen from the glass panel.

"This is the high-purity graphene centrifugal extraction machine, and it is also the machine that our Kunlun will use to mass-produce graphene.

Li Ming said with a faint smile.

As soon as this word came out.

There was a sudden silence!!

All the battery R&D personnel were shocked!!!

good guy!!

Mass production of graphene?!!

real or fake??

when they come.

Still wondering whether the boss wants to purify graphene by himself, or directly buy high-quality graphene produced by other scientific research laboratories.

certainly.

That price is almost the same as "black gold".

And now.

The boss actually opened his mouth to tell them.

There is a graphene mass production equipment inside the battery factory?!!

"Hiss!!!"

Chen Zhou couldn't believe it: "Boss, you mean this equipment can realize mass production of graphene, what about its cost?"

Li Ming said with a smile: "The cost is of course based on the cost of natural graphite. Of course, the efficiency of artificial graphite will be higher, because the nature and shape of artificial graphite are more stable, but the price is also more expensive. According to the battery pack on the Qinglong

Calculating the volume ratio, the cost of producing a graphene battery will not exceed 80,000.

Kunlun currently produces a ternary lithium battery pack with a cost of 100,000 yuan, and the external price is 90,000 yuan.

The graphene battery is slightly less than the double cost of the ternary lithium battery.

despite this.

Also extremely scary!!!

Everyone could hardly believe what they heard.

what does that mean??

Even if it sells high-purity graphene exclusively, Kunlun will become a world-class chemical company!!

"Okay, let's close the emotions at 387 first, I want to see the graphene battery go offline today!

See the expressions of everyone.

From stunned, to extremely shocked...

Then it got to a point of collapse.

Li Ming quickly stopped it.

A high-purity graphene battery is not just about pouring all graphene-made cells into it.

Inside the cell of the battery, it is not only necessary to achieve high purity and high proportion.

There are also strict chemical ratio and chemical structure design.

otherwise.

There is no need for them to study the architecture technology of graphene batteries in advance.

Everyone swallowed their saliva.

They believe in what the boss says.

Soon he looked refreshed.

Follow the boss's instructions to operate near the equipment and the robotic arm.

Li Ming put a large amount of prepared natural graphite into a high-purity graphene centrifugal extractor.

"Buzz..."

The vacuum environment inside the high-purity graphene centrifugal extractor is rapidly heated to produce a property change, resulting in atomic evaporation, and the huge power used by it can make the factory's circuits start to operate.

Graphene is produced in high purity and its chemistry can be molded into any desired shape.

And this battery production line has also started.

Purify other required chemical materials.

And will be separated and proportioned.

With the operation of the production line.

Everyone's breathing became tense!!

Time passed by every minute and every second.

end of line.

A battery pack with complete specifications appeared in front of everyone.

It has the same technological appearance as the ternary lithium battery pack.

Its external liquid-cooled heat dissipation system reduces a day and a half.

Because graphene battery itself has super heat dissipation performance.
