Start as a top student and move towards the stars and the sea

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

"Mr. Xu, classmate Ning Chen, I saw in the paper that although the new silicon-based negative electrode lithium battery can increase the energy density by about 40% compared to 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 result. So far, we have not solved this problem, but now we have some preliminary ideas and 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 deliberately in front of Xu Shou or if he really had some solution.

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 learned today, and then we will decide on the next cooperation plan."

"Okay, Manager Xu, please walk slowly."

After sending Xu Shou away, 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 it can be tried."

Hearing what Xu Zhou said, Ning Chen became excited.

"Teacher Xu, tell me what you think."

"During our previous experiments, the reason why the life of the silicon-based negative electrode lithium battery decreased was because the volume of the silicon material continued to expand during the cycle, thus affecting the cycle performance of the silicon, which in turn led to the loss of lithium batteries. lifespan is reduced."

Ning Chen also nodded when he heard this. He knew these reasons too.

"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 substances should be able to promote electronic conductivity and reduce the polarization of the silicon material. , and improve the rate performance of silicon materials. In this way, the volume expansion of silicon during cycling can be inhibited."

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

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

"That's right! We thought of it together. The ductility of metal can theoretically restrain the volume expansion of silicon-based materials. In this way, 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, the high battery energy density advantage of the silicon-based anode material will theoretically be weakened. However, as long as the modified solution has stronger comprehensive performance, it will have a chance to enter the application stage. of."

"Yes, Teacher Xu, what we have to do next is to find the appropriate metal substance to add, as well as the proportion and material combination. I also think this is a solution that can be tried."

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

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 have not been really applied in the next ten years or so, Ning Chen dare not be sure about this after all. Maybe Ning Chen just doesn't know the relevant applications.

What's more, his rebirth has already produced subtle changes in the 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 no longer felt any burden in his heart.

…

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

"Mr. Wang, I think we can cooperate with Shengzhou University. Shengzhou University's materials major is among the best in the country, and although Professor Xu Zhou is young, his professional ability is still very strong, and he has published many results. There is also a young man named Ning Chen in this experimental group, and he was the one who won the prize in the Qiu Chengtong College Student Mathematics Competition."

"Well, then Manager Xu, if there is no problem, let's try to finalize the cooperation. This may be one of the few opportunities we have. I hope everything goes smoothly."

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

"Teacher Xu, let me tell you that for this project, the company can provide up to 10 million research funds. Of course, even if the final research process is not as satisfactory, we will pay a certain proportion of the funds. , you don’t have to worry about this.”

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

Although they all know that not all scientific research funds for horizontal topics are paid to scientific researchers, but also include school management fees, various equipment costs, material costs, etc.

But a 10-million-dollar horizontal subject would definitely be considered 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 Xuzhou carefully read the contents of the contract, he communicated about some details of the contract and finally reached an agreement.

"Teacher Xu, please go through the procedures at the school. I will also ask the company to prepare the relevant procedures."

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

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

This is the first time that Xuzhou has received such a large-scale horizontal project. If this project can be completed well, getting high remuneration is only one of them, and it will also be of great help to future professional title evaluations.

Xu Zhou knew that he was able to receive this project largely because of Ning Chen's guidance.

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

"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 not wait until the project is officially approved. Let's start the relevant experiments tomorrow. Anyway, the experiment period should be very long, and we can't just wait here forever."

"Okay, I will come to the laboratory as long as nothing happens starting tomorrow." 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 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 horizontal projects, Ning Chen also wants to upgrade his materials science subject level to Lv2, and doing experiments is a faster way to accumulate subject experience.
