Chapter 94 1000 Horizontal Projects

After listening to Xu Zhou and Ning Chen's narration, Xu Shou asked:

"Mr. Xu, classmate Ning Chen, I read in the paper that although the new silicon-based negative electrode lithium battery can increase the energy density by about 40% compared with the normal carbon negative electrode battery, the battery life will be greatly reduced. I don't know. What do you two think about this issue?"

"Indeed, this is an important problem that limits the application of this achievement. So far, we have not solved this problem, but now we have some preliminary ideas, and we will try to solve this problem in future research .”

Hearing Xu Zhou's words, Ning Chen was also stunned for a moment.

"Teacher Xu...do you really have some ideas to solve this problem?"

Ning Chen didn't know whether Xu Zhou said this on purpose in front of Xu Shou, or if he really had some way.

But no matter what, Ning Chen would definitely not ask Xu Zhou on the spot, he would ask after Xu Shou left.

"In this way, Mr. Xu, I will first give feedback to the company on what I have learned today, and then we will decide on the next cooperation plan."

"Okay, Manager Xu, go slowly."

After seeing off Xu Shou, Xu Zhou and Ning Chen returned to the laboratory and closed the door.

"Teacher Xu, do you really have a solution to the problem?"

"Well, these days I have been studying the details of our previous experiments. Although I am not sure whether these plans will really work, at least I can try."

Hearing what Xu Zhou said, Ning Chen also became excited.

"Teacher Xu, tell me what you think."

"During our experiments, the reason why the life of lithium batteries with silicon-based negative electrodes declined was that the volume of silicon materials continued to expand during the cycle, which affected the cycle performance of silicon, which in turn caused lithium batteries to life expectancy is reduced."

Ning Chen also nodded when he heard the words, and he was clear about these reasons.

"My idea in the future is to change the composition of the silicon-based negative electrode. I want to add other substances to the negative electrode material to form a new negative electrode material. The added substance should be able to promote electronic conduction and reduce the polarization of silicon materials , and improve the rate performance of silicon materials. In this way, the volume expansion of silicon during cycling can be suppressed."

Hearing Xu Zhou's explanation, Ning Chen suddenly thought of something.

"Mr. Xu, do you want to add some metal substances to the silicon-based negative electrode material?"

"That's right! We thought of going together. The ductility of metals can theoretically suppress the volume expansion of silicon-based materials. In this case, it is possible to extend the life of silicon-based lithium batteries."

Xu Zhou's method is indeed a method that can be tried, which gives Ning Chen hope to solve these problems.

"Of course, since other metal substances are added, it will definitely weaken the advantage of high battery energy density of silicon-based negative electrode materials in theory. However, as long as the modified solution has stronger comprehensive performance, it has a full opportunity to enter the application stage. of."

"Yes, Mr. Xu, what we need to do next is to find a suitable addition of metal substances, as well as the ratio of addition and the combination of materials. I also think this is a solution that can be tried."

Although this improved method will not have the high battery energy density of pure silicon-based lithium batteries, it is expected to greatly increase the life of lithium batteries.

Coming out of Xuzhou's office, Ning Chen was still thinking about cooperation with Piatti.

Although according to Ning Chen's memory, silicon-based lithium batteries will not be really used in the next ten years, but Ning Chen dare not make a judgment on this after all. Maybe it's just that Ning Chen doesn't know the relevant applications.

What's more, my own rebirth has already produced subtle changes to this world. Even if the technology was not successfully applied in the previous life, it does not mean that it will not be applied in advance in this life.

Thinking of this, Ning Chen felt no burden anymore. ...

After Xu Shou finished communicating with Xu Zhou and Ning Chen, he first found a hotel near Shengzhou University to stay, and reported to the headquarters what he learned today.

"Mr. Wang, I think we can cooperate with Shengzhou University. Shengzhou University's material major ranks among the top in the country, and although this professor Xu Zhou is young, his professional ability is still very strong, and he has published many results. Yes. There is also a young man named Ning Chen in this experimental group, he was the one who won the prize in the Qiucheng Tong College Math Competition before."

"Well, Manager Xu, if there are no problems, let's try to finalize the cooperation. This may be one of the few opportunities we have, and I hope everything goes well."

The next morning, Xu Shou came to Shengzhou University Materials Laboratory again, and talked with Xu Zhou, Ning Chen and others about some details of horizontal project cooperation.

"Mr. Xu, I'm not going to hide anything. For this project, the company can give up to 1000 million research funds. Of course, even if the final research process is not so satisfactory, we will pay a certain proportion of the funds. You don't have to worry about that."

Hearing the number "1000 million", both Xu Zhou and Ning Chen felt a little excited.

Although they all know that the scientific research funds for horizontal projects are not all paid to researchers, but also include school management fees, various equipment costs, material costs, and so on.

But the 1000 million horizontal project is definitely a big project in any school.

If the project is done well, the core members of the project will definitely be able to receive a lot of labor fees.

After Xu Zhou carefully read the content of the contract, he communicated with some details of the contract and finally reached an agreement.

"Then Mr. Xu, I will trouble you to go through the formalities at the school, and I will also ask the company to prepare the relevant procedures."

"Okay, Manager Xu, we will contact you at any time."

After sending off Xu Shou, Xu Zhou's excitement was still hard to calm down.

This is the first time that Xu Zhou has received such a large amount of horizontal project. If he can do this project well, getting a high salary is only one of the reasons, and it will also be of great help to the future job title evaluation.

Xu Zhou knew that he was able to accept this subject largely because of Ning Chen's help.

But this time, Xu Zhou hopes that he can really play a key role in the whole project and prove that he has strong enough scientific research ability.

"Ning Chen, you should be able to participate in this project, right?" Xu Zhou asked.

"Of course, this is an extension of my previous project, and I will definitely participate."

"Well, let's start the relevant experiment tomorrow without waiting for the project to be officially approved. Anyway, the experiment cycle should be very long, so we can't just wait here forever."

"Okay, from tomorrow onwards, as long as there is nothing else to do, I will come to the laboratory." Ning Chen agreed.

Ning Chen did not ask Xu Zhou how to allocate the labor costs for this horizontal project in the future.

However, relying on his own understanding of Xu Zhou, Ning Chen believed that Xu Zhou would definitely not treat him badly.

……

In the following days, Ning Chen came to Xuzhou's laboratory almost every day to participate in the experiments.

In addition to completing the horizontal project, Ning Chen also wanted to upgrade his material science subject level to Lv2, and doing experiments is a faster way to accumulate subject experience.
