Seeing Su He talking there, He was a little surprised and curious.

Where did Su He come from? These things cannot be known casually.

This can be seen from the expressions of Wan Dayong and the others next to him.

He did not understand these cutting-edge knowledge, but he still knew how to look at people.

Su He talked about it: "The so-called lithium secondary battery uses lithium metal element as the negative electrode, titanium disulfide as the positive electrode, and liclo4    /dioxocene as the electrolyte.

Since lithium ions are embedded during the embedding/deintercalation process, the embedding occurs during discharge, and the lithium ions are embedded in the lattice structure of titanium disulfide; when charged, 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 is not available in general high energy density rechargeable batteries.

However, in reality, battery life is shorter than theoretical expectations, and there are problems such as poor safety performance.

Research on charge and discharge mechanisms shows that the generation of lithium dendrites is the culprit."

These are the current situation of the international community's research on lithium batteries during this period.

Of course, the country is still a little behind. Some of them learn from foreign journals.

From this passage, we can see that Su He still has a lot of understanding of lithium batteries.

The people brought by Wan Dayong were originally despised.

They already knew before they came that Su He was just a high school student.

Although this high school student seemed to have finished first in the midterm exam some time ago.

But no matter how powerful it is, it is just that.

As a result, they were all a little surprised when they heard Su He tell the history of the development of lithium batteries and the principles of lithium batteries today.

They naturally knew it, but even though they knew it, they were not as systematic as Su He said.

In his eyes, he unconsciously brought some recognition and surprise.

Director He asked, "He Zi, how do you know these?"

Su He laughed: "Although there are not many news in our country, there are still many introductions in the books. In addition, although there are few journals, I have not seen them. If you think about it carefully, you will always have some experience.

of."

Last time I was with the chemistry teacher, Su He also saw a journal.

Unexpectedly, this chemistry teacher likes to study quite a bit.

Wan Dayong became more and more excited as he heard it. He couldn't help asking: "Then do you have a solution?"

With his hope, if these problems can be solved, domestic lithium batteries will be ahead of foreign countries.

But unfortunately, Su He shook his head: "No."

Wan Dayong was very disappointed, but he felt funny in his heart.

How could Su He have a way to solve something that he can't solve?

Thinking of this, he felt that he shouldn't have come this time.

No, it’s better to come here, Su He still has a lot of ideas in this regard.

If you can study this in college in the future, it may be a lot of help.

Others were also disappointed, but they had no hope before, and there was no strong feeling of disappointment at this moment.

Su He really had no choice. He did not launch a relatively stable secondary lithium battery in his previous life until the 1990s. Until the 21st century, the safety problems of lithium batteries still occurred from time to time.

He is not a professional, so how can he solve it?

However, Su He still remembered how the people who saw in the book solved this problem before, at least significantly reducing the occurrence of danger.

"Perhaps, you can try to change the materials of the positive and negative electrodes and the components of the dissolving solution, and find a way from this aspect. There should be no way to completely eliminate them. This is related to the characteristics of lithium metal. However, by greatly reducing the danger, it will be a good idea to avoid it.

It should be possible to increase the security level to the point where it can be used in civil use."

These words seem useless, just like not saying it.

But careful savoring still provides a direction.

Wan Dayong looked at Su He and felt that Su He still had some ideas.

Since Su He had no choice for the time being, they would not stay.

But when leaving, Wan Dayong still said: "Our laboratory has some products that can be used for you. But as you said to yourself, lithium batteries are still dangerous, so you must be careful. Lock them.

The danger should be less, be careful, and it will not cause too much damage."

Su He nodded, and he accepted it when he was willing to give it to him.

Today I was giving the other party a direction and I was also a helpful person.

Director He thought to himself: "Sure enough, there is still stock. I asked last time, but I refused to give it. I came to see He Jiezi today. If I didn't say this, I'm afraid I wouldn't give it to you."

But on the surface, he did not show it.

I have been working for many years and have become scheming, so I won’t change my expression just because of some small things.

When Wan Dayong and others left, He Chu sneered: "I went to ask before, but there was no. Alas, forget it, I can't tell these researchers."

A researcher is different from ordinary people. Most of them have straight hearts and don’t have that much thought.

If he was an old man, he would definitely not say it in front of He Qu.

Even if it is said, I will definitely explain one or two sentences.

But Director Wan directly said that he had a lithium battery, and there was no explanation.

Even if He is open-minded, he will not have no idea in his heart.

Director He said goodbye and left. Su He thought about it, but still led Hei Xing out and prepared to go back.

When Su He left, Gan Yifang said with emotion: "He is really amazing. These people come here are scientists, right?"

Well, if the scientists have a broader definition, they cannot be said to be not.

Researchers who study lithium batteries are not wrong to say that they are scientists.

Ye Heng said with emotion: "It's really amazing. I haven't involved what he said."

Ye Heng thought he was a genius, and he had been practicing the Memory Palace recently, and his memory skills increased greatly. He also increased his scope of learning. Of course, most of the things he read at this stage are about accounting.

No one knows his son than his mother. Judging from Ye Heng's performance, Gan Yifang knows what he is thinking.

Gan Yifang smiled and said, "You don't have to compete with him, just compare with yourself."

Ye Heng laughed: "Mom, don't worry about me. I know what I am like. And what He Yazi said is right. It's meaningless to compare with his past self and not with others."

Su Heke didn't know what Ye Heng said. If he knew, he would definitely have to complain.

I was successful in my previous life.

But compared to Ye Heng, he is not a genius.

However, if the two lives are combined, if he can't compare to Ye Heng now, then all his days will be with dogs.
