Technological Hegemony

There was a thunder on the flat ground, and An Ran's opening made the whole world explode.

If it is said that what the western technology group has made is a technological breakthrough, it has broken through the upper limit of traditional lithium batteries and raised the energy density to the end.

Then what Star Technology does is a dimensional breakthrough!

Instead of wasting time on the traditional structure, they broke through the limitations of the dimensional wall, started anew, and redesigned the structure of the lithium battery. This is like a tiger and a cat. They are both cats, but they belong to two completely different species. .

An Ran continued his high-speed speech, and he said with a smile: "First of all, our anode material is not traditional graphite, but silicon."

"Silicon anode material has a theoretical upper limit of energy density of 3600H, which is much higher than that of graphite, and also has chemical properties similar to carbon."

"Its main defect is that when lithium ions are intercalated, the force between the ions and silicon is too significant, which significantly increases the distance between the material layers. During charging and discharging, the volume of the silicon material continues to expand and shrink. In the worst case, it can reach Four hundred percent."

"This is very deadly. As you can imagine, a battery is like magic, changing from big to small, which will bring fatal hidden dangers to the stability of the internal structure."

As An Ran spoke, she demonstrated with her hands, her five fingers separated and then closed into fists.

"A large amount of stress quickly accumulates inside the material, and it is difficult for the negative electrode to work stably for a long time. At the same time, the surface of the silicon material also needs the protection of the SEI film. The real-time change of the volume makes it difficult for the SEI film to adhere to the electrode surface stably for a long time."

"To solve this problem, we investigated an innovative technology, the carbon core."

"By the way, we need to mention that in the research of carbon materials, our materials science team of Star Technology has made a historic breakthrough."

"As we all know, our first-generation and second-generation supercapacitors use high-density carbon materials, and our Karman vortex street power generation array also uses the strongest carbon fiber skeleton in the world."

"I believe that in the near future, our achievements in carbon materials will be applied in more fields, please wait and see!"

An Ran did not hesitate to call for its own material science team, because the material science of Star Technology is really awesome, and it is the best team in the world for carbon materials, bar none.

And after a generation of genius Cao Yuan also joined Star Technology, the company's materials science team will also make great strides towards the next field of graphene.

An Ran has a straightforward personality,

Praise should be done without hesitation, and at the same time, if any laboratory in the hardware department is not doing well enough, An Ran will also scold them.

To be honest, An Ran's speech was a bit too professional. Most of the people who eat melons listened to the clouds and mountains, and the carbon core and the SEI film. What the hell is this?

However, scientific and technological workers who understand battery technology feel excited as if they have found a treasure and suddenly realized it.

They finally remembered that Xingchen Technology is a master at playing with carbon materials. They integrated their own super carbon materials into silicon anodes, and solved the problems that have plagued the scientific community for many years in one fell swoop!

Is silicon anode material good?

It's not just good, it's good!

Because anyone who has studied the field of batteries knows that the best anode materials are lithium and silicon, but at the same time, the problems of these two materials are very serious.

The problem with lithium lies in the lithium crystal dendrites, which are terrifying. They will produce countless sharp thorns during use. Once the lithium crystal dendrites pierce the diaphragm, the result will be a catastrophic disaster.

The problem with silicon is that it shrinks and shrinks, causing the stress inside the battery to change continuously. If it cannot be controlled, the result will be catastrophic.

The reason why lithium batteries use graphite as the negative electrode is not because graphite has excellent performance, but because graphite is easier to control. In terms of energy density, even the top graphite material is far worse than silicon and lithium.

"Let's go back to the design of the carbon core." An Ran said quickly, "Due to commercial confidentiality, you don't have to think about the details. I can only tell you that this technology is made of an outer layer of silicon material. It is then wrapped with a layer of carbon material, so that the layers can be used to absorb the volume change of silicon while utilizing the high capacity of silicon."

"In the end, what did we get?"

"First of all, our silicon-lithium battery has a very low discharge platform, so that it can be matched with a variety of positive electrode materials to form a high discharge voltage."

"Secondly, the lithium-silicon battery material has a strong honeycomb structure that can accommodate lithium ions. At the same time, the molecular weight of the material itself is extremely small, and it can manipulate the structure at the atomic level."

"Again, silicon-lithium batteries have dual stability in terms of structure and chemistry."

"Finally, materials are easy to obtain. After all, silicon is essentially purified sand, so our silicon-lithium batteries are relatively cheap."

First, second, again, last...

It is undeniable that An Ran is a real super genius, with clear speech and rigorous logic.

However, countless people eating melons opened their mouths wide in surprise, because they found that they couldn't understand what An Ran said...

"Isn't this too damn difficult?"

"Shouldn't there be something like a new product launch that everyone can understand? Why does it sound like a technical report?"

"As a scumbag, I feel that my IQ has been insulted today. From the beginning to the end, I figured out that the battery of Xingchen Technology is different from other companies, and I don't understand the rest."

"Hey, I'm so angry. I have studied chemistry, why can't I understand?"

The barrage was refreshed crazily, and many people showed dislike for An Ran, because listening to his speech would make people feel inferior, as if they were not from the same world.

However, An Ran didn't pay attention to this at all, he came to show off his muscles today!

Luo Jia is An Ran's boss, and also An Ran's best friend in this life. Now her best friend is regarded as a rich and unkind rich man by Fortune Magazine, and put on fire. An Ran is very angry, and the consequences are very serious.

A simple understanding of An Ran's words probably meant something like this.

I play well with carbon materials, this is called a trick, eat it all over the world!

Why did your imitated Karman vortex street power generation array collapse?

Because there is no Lao Tzu's carbon material!

Why can't you come up with supercapacitors?

Because there is no Lao Tzu's carbon material!

Why can't you solve the silicon shrinkage problem?

Or because there is no carbon material of Lao Tzu!

Lao Tzu's carbon materials are so awesome, what works well, and which field they put in, the field will be turned upside down!

Too bullying, An Ran is really too bullying today, grasping the key point of carbon materials and bragging repeatedly, so that Ji Ming and Chao Anbang, who were watching the live broadcast, blushed.

The carbon materials they make are very powerful, but not that powerful. The most critical technology for Kamen vortex street power generation is actually the fully automatic wind power assessment and management system, which is thousands of fixed wind fins on the array.

If there is no high-strength carbon fiber, at most, the life of the power generation array will be shortened a lot, and the collapse will not be so serious.

Enron is obviously playing tricks. Starting tomorrow, there will be countless laboratories in the world that will put super carbon materials as the top priority. Countless scientists are racking their brains on a pile of carbon foam, and countless scientific research funds will be thrown away. Into the bottomless pit of carbon materials.

You must know that in order to study the Karman vortex street power generation array, the western scientific community has invested countless manpower and material resources, which is also a bottomless pit.

Therefore, it is better not to offend people with high IQ, because once they start cheating people, they will really cheat people to death.

An Ran finally finished his lengthy technical speech, and the melon eaters were generally very irritable, because they didn't understand after listening for a long time.

Scientists are waking up like a dream. They secretly made up their minds to devote all their energy in this life to carbon materials, this great research field.

An Ran cleared her throat and said: "I think everyone is very interested. We have adopted a new structure. How much energy density can the silicon-lithium battery achieve?"

"I'm ashamed to say that because we have to use carbon materials to solve the shrinkage problem of the silicon anode, the final finalized product can't reach the energy density of the pure silicon anode, only 2000H level!"
