Chapter 230: Lithium silicon battery was born, 2,000 WH level!

With a thunder on the ground, Enron's opening made the whole world explode directly.
If the Western Technology Group made a technological breakthrough, it broke the traditional lithium battery upper limit and raised the energy density to the end.
So what Xingchen Technology has done is a breakthrough in dimension!
Instead of wasting time on the traditional structure, they broke the limitation of the dimension wall, started a new stove, and redesigned the structure of the lithium battery. This is like a tiger and a cat. They are felines, but belong to two completely different species. .
Enron continued his high-speed speech and said with a smile, "First of all, our anode material is not traditional graphite, but silicon."
"The silicon anode material has a theoretical energy density of 3600H, which is much higher than graphite, and also has similar chemical properties to carbon."
"The main drawback is that when lithium ions are embedded, the force between the ions and silicon is too significant, which significantly increases the distance between the material layers. During the charging and discharging process, the volume of the silicon material continues to expand and shrink. The most serious degree can reach Four hundred percent. "
"This is very deadly. Everyone can imagine that a battery can become magical, and it can become a fatal hidden danger to the stability of its internal structure.
Enron said while doing a demonstration with his hands. After the fingers were separated, there were fists together.
"A lot of stress accumulates quickly inside the material, and the anode is difficult 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 for a long time."
"To solve this problem, we have studied an innovative technology, the carbon core."
"By the way, in terms of carbon materials research, our material science team of Star Technology has made a historic breakthrough."
"As we all know, our first and second generation supercapacitors use high-density carbon materials. Our Carmen Vortex Power Generation Array also uses the strongest carbon fiber skeleton in the world."
"I believe that in the near future, the results we have achieved in carbon materials will be applied to more fields, please wait and see!"
Enron did not hesitate to call for its own material science team, because the material science of Xingchen Technology, which is really Niucha, is the best team of carbon materials in the world, none of them.
After a generation of genius Cao Yuan also joined Xingchen Technology, the company's material science team will also make great strides in the next field of graphene.
Enron's character is upright, and he should boast, and never regret it. At the same time, if any laboratory in the hardware department does not do well enough, Enron will also scold others.
To be honest, Enron's speech is a bit too professional. Most of the people who eat melon listen to the clouds around the mountains, and they are also carbon cores and SEI films. What are these things?
However, the science and technology workers who understand battery technology have a kind of exhilaration as if they were treasured.
They finally remembered that Xingchen Technology is a master of playing carbon materials. They integrated their own super carbon materials into silicon anodes, which solved the problems that have plagued the scientific community for many years!
How about silicon anode material?
It's more than good, it's just great!
Because anyone who has studied the field of batteries knows that the most important anode materials are lithium and silicon, but at the same time, the problems of these two materials are very serious.
The problem with lithium is lithium crystals, which are terrifying. It will produce countless sharp thorns during use. Once the lithium crystals pierce the diaphragm, the result will be a disaster of destruction level.
The problem with silicon is that it shrinks, and it suddenly changes, causing the stress inside the battery to change constantly. If it can't be controlled, the result is also catastrophic.
The graphite used in lithium batteries as the negative electrode is not because of its excellent performance, 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 go back to the design of the carbon core." Enron quickly said, "Due to trade 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. Wrap a layer of carbon material on top of each other to absorb the volume change of silicon while using 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, which can be combined with a variety of positive electrode materials to form a high discharge voltage."
"Secondly, the silicon lithium battery material has a strong honeycomb structure that can hold lithium ions. At the same time, the material itself has a very small molecular weight and can be arranged at the atomic level.
"Again, lithium-lithium batteries have both structural and chemical stability."
"Finally, materials are easy to obtain. In the final analysis, silicon is essentially purified sand, so the cost of our lithium silicon battery is relatively low."
First, second, again, and finally ...
There is no denying that Enron is a true super genius, with a clear and logical speech.
However, countless people who eat melons were surprised to open their mouths, because they found that what Enron was talking about, they did not understand ...
"It's too difficult for Nima?"
"Should something like a new product launch be understood by everyone? How can I listen to a technical report?"
"As a student, I feel that IQ has been insulted today. From beginning to end, I figured out that Xingchen Technology's battery is different from other homes, and the rest don't understand anything."
"Hey, I'm so angry. I've obviously studied chemistry, so why can't I understand?"
The barrage frantically refreshed, and many people showed dislike for Enron, because listening to him would make people feel inferior, as if they were not in the same world.
However, Enron didn't care about this at all, he is here to show muscles today!
Luo Jia is the boss of Enron and the best friend of Enron's life. Now his best friend is regarded by Fortune Magazine as a rich and wealthy native rich man. He is grilled on the fire.
A simple understanding of Enron probably means that.
Laozi's carbon material is good, this is called a trick, eat it all over the sky!
Why did your fake Carmen Vortex Street Array collapse?
Because there is no carbon material of Lao Tzu!
Why can't you make a super capacitor?
Because there is no carbon material of Lao Tzu!
Why can't you solve the problem of silicon shrinkage?
Or because there is no carbon material of Lao Tzu!
Lao Tzu's carbon materials are so good. What do they do well, and in which field, which field will be turned upside down!
Too bullying, Enron is really too bullying today, seizing the point of carbon materials repeatedly boasting, so that Ji Ming and Chao Anbang who are watching the live broadcast, blushed.
The carbon materials they are doing are very powerful, but not so powerful. The most key technology of Carmen Vortex Power Generation is actually the fully automatic wind evaluation and management system, which is thousands of fixed wind wings on the array.
If there is no high-strength carbon fiber, at most, the life span of the power generation array will be short, and it will not be as serious as a collapse.
Enron is obviously making a difference. From tomorrow on, the number of laboratories around the world will be uncertain ~ EbookFREE.me ~ To put super carbon materials on the top priority, countless scientists are racking their brains at a pile of carbon foam. The research funding will fall into the bottomless pit of carbon materials.
You know, in order to study the Carmen Vortex Array, the western scientific community has invested countless manpower and materials, which is also a bottomless pit.
Therefore, it is better for people with high IQ not to offend, because once they start to pit people, they will really pit people to death.
Enron finally ended his long and lengthy technical speech. The people who eat melons are generally very irritated because they didn't understand after listening for a long time.
Scientists are awake like dreams. They secretly determined that they would devote all their energy in this life to carbon materials, a great research field.
An Ran cleared his throat and said, "I think everyone is very interested. We have adopted a new structure. What is the energy density of a lithium silicon battery?"
"Ashamed, because we have to use carbon materials to solve the shrinkage problem of silicon anodes, the final finalized product can not reach the energy density of pure silicon anodes, only 2000H level!"
