Reshaping life starting from the Junior Class of HKUST

Chapter 291 Byproducts of Lithium-Sulfur Batteries: PDMS Thin Films
Before school started, Wang Chao and Wu Zhe also stayed in the lithium battery laboratory.He is also familiar with the laboratory. After using the access control card to enter, he went to the locker room to change into a set of experimental sterile clothes.

After entering the laboratory, what are Wu Zhe and his team busy with?
"Report the experimental data!" Wu Zhe asked loudly.

"Professor Wu, it still doesn't work. The effect of the separator this time is not ideal. The migration of sulfide ions to the negative electrode has reached 70%."

A doctor in the project team who observed the data replied with a bit of bitterness.

After hearing this, Wu Zhe had nothing to be angry about, as he expected.This lithium-sulfur battery was much more difficult than he imagined. When he touched it, many things had already come out.But now he had to do the things that should have been there.

Fortunately, he knows the direction.Many things can be solved with more experiments.

The mainstream practice of lithium batteries is to increase the viscosity of the electrolyte, or even directly use solid materials.Or build a carbon material structure on the lithium negative electrode to limit the shape of lithium metal growth during discharge, and ensure that the negative electrode structure does not collapse after all lithium enters the positive electrode during charging.But it is not suitable for lithium-sulfur batteries.

Wu Zhe knows the method of using PDMS modified material film as a coating, but the PDMS film technology has not yet come out, let alone an improved type.

PDMS film is a colorless and transparent polydimethylsiloxane elastomer polymer membrane material formed by cross-linking reaction under special process under clean room conditions, using polydimethylsiloxane as raw material. The team led by Wu Zhe has already figured it out, and patents and papers are also being applied for and published.

Although it has not yet been used in lithium-sulfur batteries, it has already been reflected: optical transparency; heat resistance and low temperature flexibility; high dielectric strength and high resistivity; high resilience and elasticity; Gas, water vapor permeability and selectivity; biocompatibility and chemical inertness made all the professors in the School of Chemical Engineering exclaim incredible.

Now Wu Zhe's lithium-sulfur battery project cannot be successful, and a PDMS mold manufacturing patent alone is definitely worth investing in.This thing has a wide range of applications: artificial muscles, electronic skin, medical film accessories, ocean energy power generation, photovoltaic films, pressure power generation materials and other smart sensors, smart bandages and other fields; biomedical; force-sensitive sensitive films and so on. arrive.

When doing this, Wu Zhe didn't expect that this technology hadn't been clicked yet.Then click casually, just this hand.Has shocked everyone in chemistry.I have more confidence in Wu Zhe's lithium-sulfur battery project.

Just, on the improvement of PDMS film.Wu Zhe is a bit at an impasse. The structure of this thing is changeable, and the PDMS film that is most suitable for lithium as the negative electrode has not been found.

Wu Zhe fell into thinking, and the content of the volumetric chemistry that he had read before came to his mind.

"Should we use mathematics to solve chemistry problems?" Wu Zhe murmured.

After Wang Chao came in, seeing that Wu Zhe had been thinking about the problem, he didn't dare to disturb him.After meeting Wu Zhe, he finally came to say hello: "Azhe! Are you free now?"

Seeing that it was Wang Chao, Wu Zhe withdrew his thoughts.He joked with a smile: "You don't have class, what are you doing here? The competition in the afternoon is afraid of losing, so you are hiding?"

"Am I afraid of them? Let them do whatever they want! What can I do for you?"

Seeing that Wang Chao was in a hurry, Wu Zhe stopped joking and waited for him to continue.

"Jiang Ziyi and the others are ready and ready to fight at any time. They are all waiting for your instructions!"

"Go, go out and talk to them on the phone." After Wu Zhe finished speaking, he dragged Wang Chao out of the laboratory.

There is no way to talk in here, not only the mobile phone cannot be brought in, but also the memory such as the U disk cannot be taken out.There are special inspections every day in and out, and the degree of confidentiality is quite high.

The two changed their clothes and came to Wu Zhe's office.

"Hey, the treatment of being a professor is indeed different." Wang Chao looked around and said.

This office is used by Wu Zhe alone, and the size and decoration are very good.At least it is much stronger than Zhang Detong's office.

"I want to drink tea and make it myself. There are tea leaves in the cabinet over there." Wu Zhe didn't even bother to talk to this kid.

"Don't you have Coke and Sprite here? Isn't it a bit weird for us to drink tea at this age?"

Wang Chao was not too polite, making tea and joking beside him.

"Everyone who comes to my office is an old professor. I give them Sprite? What are you thinking? Okay, don't be poor, tell me what's going on?"

Seeing Wu Zhe asked a serious question, Wang Chao's expression became serious.

"Now everything is ready. Brother Jiang's bottom position has been built. The stocks are borrowed from major brokerages and banks. Of course, they have also received a little in the stock market."

Wu Zhe nodded and asked, "What about manpower? Is it enough?"

"Brother Liao's manpower is already ready, and the company is also in order. It won't delay our actions." Wang Chao replied quickly, and then said:
"The funds have been delegated to the senior sisters, and the funds we can manipulate now are about 120 billion. These funds do not use the money in our own accounts, but commercial loans. The mortgage is a part of foreign stocks, so that they If Bian detects something is wrong, it will be difficult to find out who it is from the funds?"

Wang Chao has not been idle recently, he is still very concerned about the company's affairs, and he also knows what Wu Zhe wants to know.

Wu Zhe made some calculations and said to Wang Chao, "Did Brother Shen and those young and old inform you?"

Wang Chao rolled Wu Zhe's eyes and said, "You haven't said anything yet, I'm calling you a fart. We are the main force in this matter, and they are just beating the side drum."

"The most important thing is being able to withstand the administrative order. Otherwise, there is such a big loophole in the Shi family. I don't believe that no one will find it. It's just that many people are afraid to move because of the factors of the Chen family."

Wu Zhe is much more transparent than Wang Chao. Although Wang Chao is precocious, he hasn't grown to that level after all.Power is much more terrifying than money.

"Okay, I'll let them know later." Wang Chao nodded. Although he didn't know much about it, it didn't prevent him from following Wu Zhe's orders.

"Then tell us to start! I'll go back to the lab!" Wu Zhe stood up and wanted to go back to the lab. He was still thinking about the quantum chemistry that just flashed in his mind.

"Hey! You just left?" Wang Chao was stunned.

"Why don't you leave? It's all planned! I still have a lot of things to do." Wu Zhe asked in surprise.

"What we have to deal with now is a group of hundreds of billions, the two top families in the country. Are you so careless? Are you not nervous at all?"

Wang Chao pulled Wu Zhe and refused to let him go. He was left here alone. He had no idea, "I'm still a child! Do you have the heart to put my child under such pressure?" After speaking, he looked at Wu Zhe pitifully.

"Hey! And you, Young Master Wang, are you afraid?" Wu Zhe wanted to laugh a little, but thinking about Wang Chao's age and experience, after all, he is not the all-powerful private equity boss in later generations, so it is normal to be nervous.

"Am I afraid?" Wang Chao replied stiffly, "Anyway, you are with me, and you can rest by the side, but you can't go back to the laboratory."

Wu Zhe shook his head helplessly, spread his hands and said, "Bring the phone!"

Wang Chao quickly handed over the phone.

Wu Zhe dialed Jiang Ziyi's phone number, without any pleasantries, he just said softly: "I'm Wu Zhe, let's start!"
