Seeing Su He talking eloquently over there, He Jue was a little surprised and a little curious.
Where did Su He get this knowledge? These things are not something that can be known casually.
This can be seen from the expressions of Wan Dayong and others next to him.
He Ju doesn't understand these advanced knowledge, but he still knows how to read people.
Su He talked eloquently: “The so-called lithium secondary battery uses lithium metal as the negative electrode, titanium disulfide as the positive electrode, and liclo4/dioxane as the electrolyte.
Due to the intercalation/deintercalation process of lithium ions, the embedding occurs during discharge, when lithium ions are embedded into the lattice structure of titanium disulfide; during charging, the lithium electrons return to their original state.
This process does not affect the lattice structure of titanium disulfide, so it has good reversibility.
This gives lithium batteries a high cycle life that ordinary high-energy-density rechargeable batteries do not have.
However, in practice, the battery life is shorter than theoretical expectations and there are problems such as poor safety performance.
Studying the charge and discharge mechanism shows that the formation of lithium dendrites is the culprit. "
These are the current status of lithium battery research in the international community during this period.
Of course, China is still lagging behind. Some of them learned some things abroad, and some learned them from foreign journals.
It can be seen from this paragraph that Su He still has a lot of knowledge about lithium batteries.
The people brought by Wan Dayong originally had some contempt.
They already knew before they came that Su He was just a high school student.
Although, this high school student seemed to have ranked first in the midterm exam some time ago.
But being the first among high school students, no matter how powerful they are, is just like that.
As a result, they were all a little surprised when they heard Su He talk about the development history of lithium batteries and the principles of lithium batteries today.
Of course they knew it, but they knew it, and it wasn't as systematic as Su He said.
There was some recognition and surprise in his eyes unconsciously.
He Ju asked: "He Yaozi, how do you know this?"
Su He laughed: "Although there is not much news about this in our country, there are still many introductions in books. In addition, although there are few journals, it is not that I have not seen them. If you think about it carefully, you will always have some insights. of."
Last time at the chemistry teacher's place, Su He also saw a journal.
Unexpectedly, this chemistry teacher really liked learning.
The more Wan Dayong listened, the more excited he became, and he couldn't help but ask: "Then do you have a solution?"
He hopes that if these problems can be solved, domestic lithium batteries will be ahead of foreign countries.
But it was a pity that Su He shook his head: "No."
Wan Dayong was very disappointed, but he also felt funny in his heart.
How could Su He solve something that he couldn't solve himself?
Thinking about it this way, he felt that he shouldn't come this time.
No, it doesn't matter if you come here, Su He still has great ideas in this regard.
If I can study this in college in the future, it may help a lot.
Others were also disappointed, but they had no hope before, so they didn't feel so strongly disappointed now.
Su He really had no choice. In his previous life, it was not until the 1990s that relatively stable secondary lithium batteries were introduced internationally. Until the 21st century, safety issues with lithium batteries still occur from time to time.
He is not a professional in this field, so how can he possibly solve it?
However, Su He still remembered how he had read in the book how others had solved this problem, at least to significantly reduce the risk.
"Perhaps, we can try to change the materials of the positive and negative electrodes, as well as the composition of the solution, and think of ways from this aspect. There should be no way to completely eliminate it. This is related to the characteristics of lithium metal. However, greatly reducing the risk will It should still be possible to improve the safety level to the point where it can be used by civilians."
These words seemed useless, as if they were not said at all.
But if you look carefully, it still provides a direction.
Wan Dayong looked at Su He and felt that Su He still had some ideas.
Since Su He had no other solution for the time being, they would not stay.
But when leaving, Wan Dayong still said: "We still have some products in the laboratory that can be used by you. But as you said, lithium batteries are still dangerous, and you should be careful yourself. Lock down The risk shouldn't be great, if you be careful, it won't cause too much harm."
Su He nodded. If someone was willing to give it, he would take it.
Today can be regarded as giving the other party a direction and helping.
But He Ju secretly said in his heart: "Sure enough, there is still some stock. I asked last time, but they refused to give it to me. I came to see He Yaozi today. If I hadn't said this, I'm afraid I wouldn't give it to him."
But on the surface, he didn't show it.
I have been working for many years and have a city government. I will not change my expression because of trivial matters.
After Wan Dayong and others left, Director He sneered: "I asked before, but it was not there. Hey, forget it, I can't tell these researchers."
Researchers are just different from ordinary people. Most of them are straightforward and don't have that much thought.
If he was a veteran, he would definitely not say it in front of He Ju.
Even if I say it, I will definitely explain a sentence or two.
But Director Wan directly said that he had lithium batteries without any explanation.
Even if He Bureau is open-minded, it is impossible for him to not have any ideas in his heart.
He Ju said goodbye and left. Su He thought about it and took Black Star out and prepared to go back.
When Su He left, Gan Yifang said with emotion: "He Yazi is really amazing. Are these people here all scientists?"
Well, if the definition of scientist is broader, that doesn’t mean it isn’t.
It is not wrong to say that researchers who study lithium batteries are scientists.
Ye Heng said with emotion: "It's really amazing. I didn't even touch on what he said."
Ye Heng considers himself a genius, and he has recently succeeded in practicing the Memory Palace, and his memory has greatly improved. He has also increased the scope of his studies. Of course, most of what he studies at this stage is about accounting.
Zhizi Mo Ruomu, looking at Ye Heng's performance, Gan Yifang knew what he was thinking.
Gan Yifang smiled and said: "You don't have to compare with him, just compare with yourself."
Ye Heng laughed: "Mom, don't worry about me. I know what I am like. And He Yaozi is right. You should compare yourself with your past self, not with others. It's meaningless."
Su He didn't know what Ye Heng said. If he did, he would definitely complain about it.
In my previous life, I was quite successful.
But compared to Ye Heng, he is not a genius.
However, if the two lifetimes put together are still not as good as the current Ye Heng, then he will have lived like a dog in those days.
At this time, Su He had already left the city and rushed towards Nanzhu Village.
