192: Electrochemical properties of carbon nanomaterials in lithium batteries
After speaking, Guo Hao hung up the phone.
He smiled and said to Shen Luoyan, who was standing by.
"This way, we don't have to worry about Grandpa and Grandma. Although Wang Xi usually seems unreliable, he's a good person and quite dependable in his actions. He will go take care of Grandpa and Grandma, and he'll inform us promptly if anything happens!"
"Okay!"
Shen Luoyan nodded.
"Help me thank him!"
"Okay! Don't worry!"
Guo Hao smiled. He understood very well that besides himself being a significant factor, Shen Luoyan's biggest concern about interning at Chengdu Aircraft Industry Group was her Grandpa and Grandma.
She worried a lot about them. It was understandable if she couldn't go back during normal times, but during the winter and summer breaks, which were supposed to be times for accompanying Grandpa and Grandma, she would be very worried if she wasn't there.
By having Wang Xi take care of them, Guo Hao was resolving Shen Luoyan's worries.
The next day.
According to Academician Jiang Lei's request, Guo Hao arrived at the Laboratory in the afternoon.
When he arrived at the Laboratory, there were already quite a few people there.
"Guo Hao is here!"
Academician Jiang Lei saw Guo Hao and called out with a smile.
"I'm here."
Guo Hao nodded.
"Come, let me introduce you."
Academician Jiang Lei pulled over a middle-aged man with a somewhat thin face and gold-rimmed glasses.
"This is a leading expert in the domestic lithium battery field, who enjoys special government allowances. He is also the chief scientist of the CATL, Professor Professor Wu Kai."
"Hello, Professor Wu!"
Guo Hao quickly extended his hand towards Professor Wu.
Professor Wu also shook hands with Guo Hao, a smile on his face, and looked at Guo Hao as he spoke.
"Student Guo Hao is truly a young hero! I have read several of your papers. The computational methods are very novel. Those papers are only considered good in the field of Mathematics, with very new computational methods.
However, they can have a profound impact on the field of Chemistry. I feel that the potential of your two papers still has a lot that can be explored. Therefore, I specifically invited you to join the research group this time. Welcome to join!"
"Thank you for the compliment."
Guo Hao said with a smile.
Although scientists also chat casually, it is usually only in very informal settings that they occasionally chat. Right now, in the Laboratory, no one would chat casually.
Everyone sat down in the Laboratory's conference room.
Professor Professor Wu Kai stood next to a whiteboard.
"This time, our research topic is on the electrochemical properties of carbon nanomaterials in the field of lithium battery. This research is funded by the CATL. The CATL will provide a daily research compensation to the researchers participating in this project.
Then, if this research makes progress, we will give everyone sufficient share rewards and bonuses based on the technical prospects and application directions."
Professor Professor Wu Kai said to everyone with a serious expression.
Electrochemical reaction is mainly an interfacial behavior, which primarily occurs at heterogeneous interface layers and is closely related to the formation of chemical bonds at solid and fluid interfaces.
Spatially, the electrochemical reaction site can be divided into three parts: material bulk phase, interface, and electrolyte components. Firstly, the intrinsic properties of the material largely determine the voltage, which is crucial for understanding charge transport mechanisms, electronic structure, and evaluating the migration of atoms from the bulk phase to the surface during the entire electrochemical process. This affects electrochemical reactivity and overall stability.
Secondly, the solid-liquid interface mainly includes several (two to three) heterogeneous interfaces, which is also the region where electrolyte molecules/ions combine with the solid electrode surface, and also the site of electron transfer.
And carbon nanotubes, due to their excellent electrical conductivity, thermal conductivity, mechanical properties, and unique structural morphology, can theoretically be used to improve the stability and stability of lithium ion electrolytes, and can enhance battery performance.
Guo Hao recalled some issues about electrochemical reactions in his mind.
During this time, Guo Hao had not only read Mathematics and Physics books, but also took time to read many professional books related to Chemistry, and he had some understanding of these.
The CATL was remarkable. In later generations, it was a super-large enterprise with a market value of trillions.
As for remuneration, there was no need to worry.
"I have no problem."
Guo Hao said straightforwardly.
He came to do experiments mainly for learning and growth, and to see if he could gain some experience or something. Guo Hao didn't expect to be able to take the lead.
After all, many things in chemical reactions are extremely complex reactions.
Especially this kind of electrochemical reaction.
Guo Hao was not confident in being able to build a model, unless there was enough data, in which case Guo Hao could try a little, but it was still highly likely to fail.
Because chemical reactions are too complex, involving many changes.
The reactions within the battery itself are already fantastical enough. Up to now, humans still don't fully understand the growth mechanism of lithium dendrites, and once they appear, most of the time, they will cause significant consequences.
If the principle is not understood, the data itself is useless.
Professor Professor Wu Kai briefly talked about his concept, and Academician Jiang Lei also briefly talked about his idea.
The two discussed for a while.
Guo Hao had been listening attentively the whole time.
Guo Hao had more or less heard of some of the theories they discussed, but the viewpoints were quite novel.
Soon, the two roughly discussed an experimental process.
Professor Professor Wu Kai, who was next to him, looked at Guo Hao, who was listening attentively, and smiled slightly.
"Student Guo Hao, do you have any thoughts?"
Guo Hao shook his head.
"Unlike ordinary single materials, lithium battery electrolyte involves many aspects, and the properties of the electrochemical interface are also constantly changing, and within this variable.
According to your and Academician Jiang Lei's ideas, adding materials like carbon nanotubes as new variables, it is difficult to establish effective data modeling in such a complex scenario with mathematical modeling."
Guo Hao spoke truthfully.
"Hahaha, don't worry, we are still discussing. You can also talk about your own thoughts. How do you think your Computational Materials Science can be effective in it?"
Professor Wu Kai smiled slightly and asked Guo Hao in front of him.
"We need to reduce the variables."
After a moment of contemplation, he looked at Professor Professor Wu Kai in front of him and said.
"The intrinsic properties of the material largely determine the voltage. We can conduct separate research through the material itself. After determining the data through research, we can find an optimal solution through computational modeling.
Each part is calculated separately, and then combined. In the process of combination, we conduct secondary modeling again."
What Guo Hao said was very complex. There was no way around it, since there were so many variables, the model also needed to be optimized!
