A thunderclap on the ground and a safe opening made the whole world explode.

If Western Technology Group made technological breakthroughs, broke through the upper limit of traditional lithium batteries, and increased the energy density to the end.

Then what Xingchen Technology does is a dimensional breakthrough!

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

An Ran continued his high-speed speech, and he smiled and said, "First of all, our negative electrode material is not traditional graphite, but silicon."

"Silicon negative electrode material has a theoretical energy density upper limit of 3600wh, which is far higher than graphite and also has chemical properties similar to carbon."

"The main disadvantage is that when lithium ions are embedded, the force between the ions and silicon is too significant, which makes the distance between the material layer significantly larger. During the charging and discharge process, the volume of the silicon material continues to expand and contract, and the most seriousness can reach 400%.

"This is very fatal. You can imagine how fatal a battery is like a magic trick, and it will cause a small and small amount of internal structure."

An Ran said while using her hands to demonstrate, and her five fingers were separated and they were fists together.

"A lot of stress accumulates quickly inside the material, making it 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 have studied an innovative technology, carbon nuclear.”

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

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

"I believe that in the near future, the achievements we have made in carbon materials will be applied in more fields. Please wait and see!"

An Ran is not stingy in all his materials science team, because Xingchen Technology's materials science is really awesome, and he is the best team to play carbon materials in the world, no doubt about it.

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

An Ran has a straightforward personality and praises him when he should, and never stingy. At the same time, if any laboratory in the hardware department is not good enough, An Ran will also scold people.

To be honest, An Ran’s speech is a bit too professional. Most of the melon-eating people listen to it, with a carbon core and a sei film. What is this?

However, scientific and technological workers who understand battery technology have a feeling of excitement as if they are a treasure and suddenly realize it.

They finally remembered that Xingchen Technology is a top expert in playing carbon materials. They incorporated their own super carbon materials into the silicon negative electrode, solving the problems that have plagued the scientific community for many years in one fell swoop!

Is the silicon negative electrode material good?

More than just good, it's so good!

Because anyone who has studied the battery field knows that the most awesome negative electrode materials are lithium and silicon, but at the same time, the problems of both materials are very serious.

The problem with lithium is that lithium crystal branches are terrifying. Li crystal branches will produce countless sharp thorns during use. Once the lithium crystal branches pierce the diaphragm, the result will be a disaster of destruction.

The problem with silicon is shrinkage, which is too big and sometimes small, causing the stress inside the battery to change continuously. If it cannot be controlled, the result will be at a disaster level.

The graphite used as the negative electrode of lithium batteries is not because of the excellent performance of graphite, but because graphite is easier to control. In terms of energy density, even the top graphite materials are far worse than silicon and lithium.

"Let's continue to return to the design of carbon core." An Ran said quickly, "Due to the commercial secrets, you don't need to think about the specific details. I can only tell you that this technology consists of a layer of silicon material and then a layer of carbon material. This layer of stacking can use the high capacity of silicon while absorbing the volume changes of silicon."

"In the end, what did we get?"

"First of all, our silicon lithium batteries have a very low discharge platform, which allows a variety of positive electrode materials to cooperate with them to form a high discharge voltage."

"Secondly, silicon lithium battery materials have a powerful honeycomb structure that can accommodate lithium ions. At the same time, the material itself has a very small molecular weight and can merge atomic-level structural composition."

"Again, silicon lithium batteries have dual stability in terms of structure and chemical aspects."

"In the end, the material is easy to obtain. After all, silicon is essentially purified sand, so our silicon lithium battery is relatively cheap."

First, second, again, last

Undeniable that An Ran is a true super genius, with clear speeches and rigorous logic.

However, countless people who were eating melons opened their mouths in surprise because they found that they could not understand what An Ran said.

"This is too difficult, right?"

"Something like a new product launch conference shouldn't be said to be something that everyone can understand? Why does it sound like a technical report?"

"As a poor student, I feel that my IQ is insulted today. From beginning to end, I figured out that Xingchen Technology's battery is different from other companies, and I don't know anything else."

"Hey, I'm so angry. I've obviously learned chemistry, so why can't I understand?"

The barrage was refreshed in a crazy way, and many people showed dislikes to An Ran, because listening to him would make people feel inferior, as if they were not from the same world.

However, An Ran ignored this trick at all, and he was here to show off his muscles today!

Luo Jia is Anran's boss and Anran's best friend in his life. Now her best friend is regarded as a rich and unkind local rich man by Fortune Magazine. She is roasted on the fire. Anran is very angry and the consequences are very serious.

If you simply understand An Ran, that's what it means.

I have a good time playing with carbon materials, which is called a skillful trick and can eat all the time!

Why did your imitation of Carmen vortex power generation array collapse?

Because I don’t have my carbon materials!

Why can't you make supercapacitors?

Because I don’t have my carbon materials!

Why can't you solve the problem of silicon shrinkage?

It’s because I don’t have my carbon materials!

My carbon materials are so awesome. Whatever you do is do, what you put in, and what you put in will be earth-shaking!

It's so bullying. An Ran is so bullying today. He repeatedly boasted about the key point of carbon materials, so that Ji Ming and Chao Anbang, who are watching the live broadcast, turned red.

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

If there is no high-strength carbon fiber, at most, the power generation array has a much shorter life and will not be as severe as collapse.

An Ran is obviously doing something bad. From tomorrow on, there are countless laboratories in the world that will put supercarbon materials on the top priority. Countless scientists rack their brains to a pile of carbon foam. Countless scientific research funds will be smashed into the bottomless pit of carbon materials.

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

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

An Ran finally ended his long technical speech, and the people who were eating melons were generally very upset because they couldn't understand after listening for a long time.

Scientists woke up as if they were dreaming. They made up their minds to devote all their energy to carbon materials, this great research field.

An Ran cleared his throat and said, "I believe everyone is very interested. We have adopted a brand new structure. How much energy density can the silicon lithium battery reach?"
