Chapter 235 Breakthrough in Materials Science--LZ-1
Dr. Li is a senior researcher in the new material R&D department of Wu Zhou Company.

Graduated from Huaqing University with a major in materials science. After graduating from a bachelor's degree, he went to study abroad at the University of California, Berkeley with a full scholarship, under the tutelage of Academician Yang Peidong, a professor of the Department of Chemistry.During his overseas stay, he participated in a number of cutting-edge materials science-related research projects with his teacher, published 13 high-level papers, and obtained a doctorate.

Due to family reasons, he returned to China to continue his research in materials science and joined the top material science major in China University of Science and Technology. He has achieved outstanding results in the fields of new functional materials, nanomaterials, and biomedical materials.

He is also a genius scientist recommended by Wu Zhou's system.

As for why Wu Zhou was able to recruit him, it is very simple, as simple as one sentence, "Research whatever you want to study, without any constraints, and allocate funds at will."

Then Dr. Lee agreed.

Because in general universities want to study a project.

Some necessary steps are required.

For example, the first step is to determine your own research direction and topic. You need to find relevant literature, write a detailed research plan, and explain your research goals, methods, expected results, and innovation points.

The second step is to find a suitable funding institution, which can be a national, provincial or municipal science and technology department, or a foundation or enterprise inside or outside the school.It is also necessary to understand their application requirements, conditions, time and procedures, and choose projects that meet the characteristics and level of their own topics for application.

After everything is ready, the third step is to fill in the application form. You need to fill in the project name, person in charge information, research content, budget, etc. according to the format and requirements specified by the funding agency or project.
After that, it is time to submit the application form and wait for the review, and you will receive a notification of the review result in a few weeks or months.

How should I put it, there is nothing wrong with these procedures. The problem is that Dr. Li doesn't like these cumbersome procedures.

Moreover, many of his ideas for research projects may have been the same when they were declared, but during the research process, they suddenly changed their direction completely, and produced a completely irrelevant result.

In addition, there is still time to wait for the declaration, and in his opinion, every minute is extremely precious.

As a result, the treasure was picked up by Wu Zhou. Of course, in order to recruit him as a big cow, Wu Zhou communicated in person and gave a promise in black and white.

Dr. Li excitedly rushed into Wu Zhou with a report and said loudly, "Boss, big discovery, big discovery!" The excitement on Dr. Li's face was beyond words.

Wu Zhou looked at the very 'immature' Dr. Li, who was at least ten years older than himself, but still smiled, "It seems to be a really big discovery? Let me see." Wu Zhou took the report from Dr. Li.

Dr. Li said directly at this time, speaking very fast, "Look at this, this is a new type of compound that our laboratory accidentally discovered, and I will call it LZ-1 for the time being. Our laboratory is currently studying a new type of antibacterial compound. I discovered it by accident when I was working on a peptide. This new type of compound has strong hydrophilicity and lipophilicity, and can self-assemble into a structure similar to cholesterol in aqueous solution. I have a small eDonkey, and the battery life has dropped dramatically. I Just thinking about it, try to see if it can be used as an electrolyte salt additive to improve the performance of lithium-ion batteries. I added it directly last weekend, and the battery life was restored to when I bought it, and the charging time was also saved. 15%, very easy to use!"

"During this time, our group has also done detailed research in the laboratory. After LZ-1 is added to the electrolyte salt, it can greatly reduce the viscosity of the electrolyte, and it is almost not affected by high and low temperatures. Under conditions, they can remain stable and will not fail and degrade.”

After speaking, Dr. Li still had an excited look on his face, but Wu Zhou gave him a slightly speechless look, "It's just an electric car. If it doesn't work, just change it. How can you add other things to the battery fluid at will?" Yes, it's very dangerous, and the company has assigned you a driver."

"Got it, got it, don't talk about this, don't talk about this, you look at the report later." Dr. Li waved his hand, showing a little impatience and disapproval, and directly turned up the book in Wu Zhou's hand Reports, to some data and graphs.

Dr. Li pointed to a table on the report and said directly, "Look here! We used LZ-1 as an additive to prepare several electrolytes with different concentrations and ratios, and compared them with commonly used electrolytes on the market. The results show that at 25°C, the viscosity of LZ-1 additive electrolyte is only about 0.5 mPa·s, while the viscosity of common electrolytes is between 1.5 and 2.0 mPa·s; at -20°C, LZ-1 The viscosity of the additive electrolyte remains at around 0.6 mPa s, while that of commonly used electrolytes soars above 10-15 mPa s; at 60°C, the viscosity of the LZ-1 additive electrolyte is only about 0.4 mPa s, while the commonly used The electrolyte drops to between 0.8 and 1.2 mPa·s." A series of values ​​came out completely, exactly the same as in the report.

In fact, these reports were not written by him, but were automatically produced by the company's AI based on the experimental data.

"So low?" Wu Zhou was also surprised when he heard the words, and opened his mouth in surprise.

"Yeah!" Dr. Li continued, "Don't interrupt me, I'm not done yet! The ion mobility of the LZ-1 additive electrolyte is also much improved due to the much lower viscosity. We measured them at Ionic conductivity and molar conductivity at different temperatures. The results show that at 25°C, the ionic conductivity of the LZ-1 additive electrolyte reaches about 12.5 mS/cm, while the common electrolyte (with LiPF6 as lithium salt) The ionic conductivity is only about 9.5 mS/cm; at -20°C"

"In addition, we also made some lithium-ion battery samples with LZ-1 additive electrolyte, and tested the charge-discharge performance and cycle life of samples made with common electrolytes. The results showed that at 25°C, The specific capacity of the sample made with LZ-1 additive electrolyte reached about 180 mAh/g, while the specific capacity of the sample made with common electrolyte was only about 150 mAh/g; The specific capacity of the sample still remains at about 20 mAh/g, while the specific capacity of the sample made of common electrolyte drops to about 1 mAh/g; at 160 ° C, the sample made of LZ-80 additive electrolyte also has 60 mAh /g or so, while samples made with common electrolytes dropped to around 1 mAh/g.”

"We also measured their cycle life at different temperatures. The results showed that at 25°C, after 1 cycles of samples made of LZ-500 additive electrolyte, the capacity retention rate reached more than 98%, while common electrolytes After 500 cycles of the fabricated sample, the capacity retention rate is only about 85%; at -20°C"

Wu Zhou watched and listened, and at this moment understood the meaning of this report, or the value of this new compound LZ-1.

"Can I talk now?" Wu Zhou asked with a smile.

"It's fine now, boss, please hurry up and say, I have other projects in progress, time is precious." Dr. Li said while looking at an electronic watch on his wrist.

"Then go get busy, and let me know if you need anything." Wu Zhou didn't waste his time.

"Okay, bye." Dr. Li turned around and left Wu Zhou's office.

Wu Zhou looked at Dr. Li who left directly, shook his head with a smile, and then sent a message to Dr. Li's assistant: "Replace his electric car with a new regular battery."
