Chapter 94 Ten Million Horizontal Topics
After listening to Xu Zhou and Ning Chen’s stories, Xu Shou asked:
“Teacher Xu, Ning Chen, I saw in the paper that the new Although silicon-based anode lithium batteries can increase energy density by about 40% compared to normal carbon anode batteries, the battery life will be greatly reduced. What do you 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. "
Ning Chen was stunned for a moment when he heard Xu Zhou's words.
"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 ideas.
But no matter what, Ning Chen would definitely not ask Xu Zhou on the spot. He would ask after Xu Shou left.
"In this case, 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, you 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 about these Whether the plan will really work, but at least it can be tried."
Hearing what Xu Zhou said, Ning Chen became excited.
"Teacher Xu, please 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. The lifespan is reduced.”
Ning Chen also nodded when he heard this, and he knew the 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 substances must be able to promote electronic conduction. Reduce the polarization of the silicon material and improve the rate performance of the silicon material. This can inhibit the volume expansion of silicon during the cycle. "
Listening to Xu Zhou's explanation, Ning Chen suddenly felt like this. Something came to mind.
"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."
< br>Xuzhou'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, theoretically it will definitely weaken the high battery energy density advantage of the silicon-based anode material. However, as long as the modified solution has stronger overall performance, it will be completely There is a chance to enter the application stage.”
“Yes, Teacher Xu, what we have to do next is to find the appropriate proportion of added metal substances and the combination of materials. I think this too. It 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 Piati.
Although according to Ning Chen’s memory, silicon-based lithium batteries will not be really used in the next ten years or so, Ning Chen does not dare to be sure about this after all. Maybe Ning Chen just doesn’t know about it. Application only.
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. He was the one who won the prize in the Qiuchengtong 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 well.”
The next morning, Xu Shou came again. The Materials Laboratory of Shengzhou University discussed some details of horizontal project cooperation with Xu Zhou, Ning Chen and others.
"Mr. Xu, I'm not hiding it. For this project, the company can provide up to 10 million research funds. Of course, even if the final research process is not so satisfactory, we will The funds are paid according to a certain percentage, so you don’t have to worry about that.”
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 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 seeing off Xu Shou, 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 have a great impact on future professional title evaluations. help.
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, I will definitely participate.”
“Well, then we won’t wait until the project is officially approved, we will start related work tomorrow Let’s do the experiment. Anyway, the experiment will take a long time, so we can’t wait here forever.”
“Okay, I will come to the lab as long as there is nothing else,” 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 Xuzhou, Ning Chen believed that Xuzhou would not treat him badly.
......
In the following time, 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.
