I am devoted to scientific research, but you want to trick me into having a love relationship?

Chapter 664 You've come up with something new again?

Inside the office.

The young man and the old man were drinking tea, each holding a document.

Quantum dot composite materials

Zhao Shengwen stared at the documents Xu Qingzhou handed him, lost in thought.

Their current experiments have truly reached a dead end, making almost no progress. They can only advance little by little, trying different experiments.

"This is the first time I've seen this material used to suppress lithium dendrites."

Zhao Shengwen said.

This young man always manages to come up with something new, unexpected, and unconventional, but countless experiments have proven that Xu Qingzhou's choice is correct.

Xu Qingzhou said in a deep voice, "I was inspired by the MoN@N-doped graphene separator that we are currently working on. Theoretically speaking, by using N-doped electron reconstruction and quantum dot confinement, we can break through the physical and chemical thresholds of dendrite suppression to a certain extent."

“It’s worth a try.”

Across from him, Zhao Shengwen looked down and carefully read through Xu Qingzhou's calculations and plan.

Xu Qingzhou didn't disturb him and looked at the data sent by Zheng Xu.

20 minutes passed.

"Based on your calculations, it looks very promising."

Looking at the model's speculative data in his hand, Zhao Shengwen's eyes were filled with undisguised amazement: "Perhaps the key to solving lithium dendrite problems really lies in this brand-new material."

Looking at the young face opposite him, the old professor was filled with emotion. Since the beginning of the experiment, it had almost been this young man who had pushed them forward, turned the tide many times, and led them to the right path.

They conducted battery experiments for four or five years, but the combined results are not as good as those achieved in just over six months.

Xu Qingzhou smiled and said, "Well, we now have a very mature graphene-based material process that can be put into experiments in the shortest possible time. You can try FeCo-N@graphene quantum dots as a negative electrode surface modification layer and see how it goes."

It's simply a matter of stuffing new materials into the battery, such as using them in the separator, electrolyte, or positive and negative electrodes.

The workload is certainly not small.

Leaving aside whether such quantum dot composite materials that can suppress lithium dendrites actually exist, even if a great deal of effort is put into finding them, the question remains: in which part of the battery should they be used?

Each mountain is more difficult than the last.

From a mathematical perspective, Xu Qingzhou believes that quantum dot composite materials are the best known option, but they have not yet been actually tested.

"Okay, I have a feeling this time might be different."

Zhao Shengwen spoke with certainty; he saw hope in Xu Qingzhou's plan.

"Practice is the sole criterion for testing truth. I only have a vague framework at the moment, and I need some time to finalize these things. Of course, the premise is that your experiments prove that FeCo-N@graphene quantum dots are effective."

Xu Qingzhou smiled and handed over another document, continuing, "This is the experimental scheme for FeCo-N@graphene quantum dots that I wrote. You are an expert in this field, so you can take a look and see how it is. If there is anything unsuitable, we can revise it."

"it is good."

Zhao Shengwen wasted no time. He put his glasses back on and looked at the plan. Having done research in condensed matter physics for decades, he was one of the most experienced people in the Chinese physics community.

Although this is the first time I've seen quantum dot composite materials used in batteries, the principle remains the same. After reviewing the plan, I already have some ideas.

Pointing to the second part, he said, "In this part, can we learn from the Mn-doped graphene preparation process and transfer the electronic control effect of N to TiO quantum dots?"

"Yes, we can add new things."

The two spent a day finalizing the experimental plan.

Xu Qingzhou has been staying at the research institute for the past two days, either going to the lab or on his way to the lab.

14pm on the 6st.

Xu Qingzhou and Zheng Xu came out of the lab. Today's experiment went smoothly. It was only 5:30, and most of the people in the lab had already left.

As Zheng Xu took off his white lab coat, he said, "I heard that Lao Zhao is testing a new material, quantum dot composite material?"

"Yes, it has a good effect on suppressing lithium dendrites."

Xu Qingzhou nodded.

"It looks like our group needs to hurry up too," Zheng Xu sighed. Colleagues may be colleagues, but both groups were secretly simmering with ambition, each wanting to produce results before the other. These past few days, the lithium dendrite group had been working with great enthusiasm, radiating energy wherever they went, which made the other group feel "threatened."

Xu Qingzhou smiled and said, "You guys are pretty fast too. Maybe you can find something in carbon materials that can completely solve the shuttle effect."

"Hopefully."

Zheng Xu shrugged. Their progress was indeed impressive. In terms of the performance of lithium-sulfur batteries alone, they were already at the forefront of the world.

"I got off work quite early today."

Xu Qingzhou was surprised to see that Zheng Xu had changed his clothes.

This Team Leader Zheng is a well-known workaholic; he practically lives in the lab, so it's rare for him to leave work early.

"Someone's coming to visit, so I have to go home early." Zheng Xu's face showed a rare smile.

"Please give my regards to your sister-in-law."

"it is good."

Zheng Xu nodded, didn't linger, and went out.

Xu Qingzhou also organized the documents and prepared to leave work.

As far as he knew, Zheng Xu would fly back once or twice a month, but living apart was not a long-term solution.

"Once the research institute's institutional framework is established, we still need to consider the issue of resettling key personnel."

Xu Qingzhou put his thoughts aside and was about to leave the shuttle effect group's laboratory when he noticed a young man deep in thought by the window on his left.

He did recall that these past few days, even at 10 p.m., he often saw this person with his head down, calculating things.

"professor."

Noticing Xu Qingzhou walk to his desk, the young man stood up.

Xu Qingzhou asked with a smile, "I often see you working overtime. Have you noticed anything interesting?"

"Take a look at this."

Ding Daoyong handed over several electron microscope drawings.

"Sulfide-ether complexes and self-assembled nanoparticles were found in dibutyl ether electrolyte waste."

Xu Qingzhou stared at the test blueprints.

The electrochemical impedance spectroscopy was abnormal, with a significant negative shift in the phase angle of the EIS phase angle data in the low-frequency region, and the peak position of the characteristic peak of the cyclic voltammetry curve was also shifted.

"That's interesting. How did you discover that?"

"I became interested because of the unusual color of the experimental waste liquid, so I tried to study it, but I found that the reason for the unusual color was different from what we knew."

Ding Daoyong said in a deep voice.

"The institute must have quite a few well-established research topics to choose from, so why did you decide to research this?"

Xu Qingzhou was curious.

He had read through several manuscripts and had a general understanding of the subject. It did not match the mainstream experiments in Zheng Xu's group and had obvious shortcomings.

Finding established research topics from research institutes to work on will inevitably make obtaining results much easier.

Clearly, this is not a "wise" choice.

Ding Daoyong scratched his head and said embarrassedly, "I found out, and I won't feel right until I figure it out."

This thirst for knowledge is admirable.

Xu Qingzhou thought to himself, and after thinking for a moment, he said, "How about this, you put together an application today, treat it as a research topic, and study it carefully."

"Okay, thank you, Professor!"

Ding Daoyong said with some surprise.

The project and his independent research are two completely different concepts. Right now, he can only occasionally use the equipment. Once the project is established, funding, equipment applications, and so on will be much easier.
