Black technology starts from the steel suit

Chapter 50 Model Assumptions for the Microstructure of Electrochemical Interfaces
"If it's convenient, can you introduce it to us?" Professor Liu asked curiously. He had a guess in his mind, but he couldn't believe it. After all, Wang Feng was only a young man in his early 20s. Is it really enough?
"There's nothing you can't say, just some ideas about the microstructure of the electrochemical interface, which are not mature enough. Although you can't show them off, you can still share them internally!" Wang Feng has nothing to hide, just like he said As I said, they are just ideas, and the least valuable thing in science is ideas.

"Regarding the research on electrochemistry, we have been continuously deepening, and now we have gone from the macro scale to the micro scale, and even to the molecular level. It is far from being expressed by a piece of zinc and a piece of copper plus an acid solution. discipline."

"Although we have indeed made quite a few breakthroughs in electrochemical theory for a long time, it is a pity that when we go deep into the microscopic field, we can only treat it as a black box."

"For example, impedance and EDLC are the objects of high attention and key analysis in electrochemistry, but if it comes to the theoretical level, we still cannot give an effective explanation because we lack effective theoretical basis."

"Even if we are a little more serious, basically most of the papers here have some unreasonable explanations. If we accept the dead truth, the papers will not be published..."

"This is indeed a big problem, but the problem is that we have no way, or the entire chemical community can't solve this problem. Compared with the great strides forward in mathematics and physics, our chemistry and biology are almost It can be said that it is advancing step by step..." Professor Liu is an old man in materials science, and he is well aware of the development of the scientific community in this area.

Thinking of this, Wang Feng couldn't help feeling that, except for mathematics and physics, the theoretical guidance of other subjects could not keep up with the pace and needs of practical applications.

"So our current research in this area is still based on feedback from practical applications to theoretical research work to improve our theories. Such research efficiency is really too low, and it is not necessarily the optimal solution..."

"There is no way, even if it is inefficient, the solution is not optimal, and it costs a lot of money, but we don't have a better alternative!" Senior Brother Hua said with emotion. Suddenly, he seemed to think of something: " Could it be, are you..."

Brother Hua held his breath, a little unbelievable, so many Tianwangfeng locked himself in the laboratory, ate and lived with them, but today he changed his normal routine and invited the master of the barbecue garden to improve his life. Does he want to witness history? Yet?

"I don't have a theory yet, but I have some rough and vague feelings. I still need more practice to perfect my theory, which is also a test. After all, studying the microstructure of the electrochemical interface is a complicated task. , and work long hours."

There is another reason why Wang Feng did not say that he will complete the establishment of his own patent building, stand up all the pits that can be occupied, and establish his own standards before he will make this work public. Otherwise, in the Western style The amount that Huaxia can share in this revolutionary feast is really very few.

"Wait, then you invite Master Ji?"

"I just want to eat barbecue!"

Huaan: (O_o)??
However, Hua An and Professor Liu also expressed their understanding, because the most important thing for scientists is inspiration, because it is not bad to celebrate.

As for the fact that he didn't explain it to them in detail, the two of them felt very itchy, but no one would present an imperfect theory as a pretense, it could easily become a joke, and it would be the laughing point of the scientific community for a whole year.

Especially now that the academia is dominated by the West, they are easily attacked by groups, not only from ridicule from foreign colleagues, but more importantly, backstabs from domestic colleagues, whether it is for profit or fame...

"Okay, let's not talk about this. You haven't introduced our latest research results to me yet. I believe you will not let me down!"

"OK, then I'll make a fool of myself." Professor Liu didn't dare to look down upon the young man Wang Feng any more. He seriously took out a dozen printed materials.

"Growing tin oxide crystals on carbon nanotubes to coat carbon nanotubes can effectively reduce the energy on its surface, thereby reducing its degree of aggregation. At the same time, because it is filled with tin oxide crystals, it can effectively reduce its structure. The attenuation of strength improves its physical properties."

"In other respects, what is its electrochemical performance?" Wang Feng asked with concern. It is not difficult to fill in the coating material, but the difficulty is not to affect its electrochemical performance too much, which is very difficult.

"There are some effects for sure, but according to our calculations, the problem is not particularly big, mainly because our doping ratio is not very high, so the impact on capacity will not be great; and the most important thing is that its electrical conductivity is very good, and It is very important that an ortho-red rutile structure can be formed after doping without affecting the deintercalation of lithium ions."

"Do you have a sample?" Wang Feng asked: "Give me a copy of the data and the sample at the same time. I want to test it. After all, laboratory testing is only one aspect, and environmental testing is the key point!"

Hua An and Professor Liu: -_-||
When they think of the military test, they feel a pain in the ass, but they can't say anything. After all, this thing is going to be on the battlefield. If you don't pass the rigorous test, how can you guarantee its reliability?
If something goes wrong with this kind of thing, it will eventually go to a military court!

"There are samples, but I'm afraid there is no way to meet the test requirements for the time being, because the battery has not yet been produced, and the yield of new negative electrode materials is very low, and it will be the morning of the next day at the earliest." Professor Liu and Hua An disagreed. Said with great embarrassment.

They use the hydrothermal crystallization method, which has the advantage of small and fine particles, which can well meet the needs of laboratory observation and testing, but the process is extremely cumbersome and the yield is low, even if they have hundreds of brickworkers working together Do, the output is not high.

"Didn't you use the sintering method?" Wang Feng frowned.

"It's the first time. After all, it has to look better. The sintering process is too rough and has a lot of defects...it won't look good if it overturns." Professor Liu's tone was not so strong. He wanted to show his best side to the leader. This is what they are best at. As for practical application and production, leave it to the industry...

"Okay, let's do this first. It's best to prepare enough samples for me tomorrow morning, and I'll take them for testing!" Wang Feng also knew that he shouldn't be too harsh, after all, not everyone is like him, but the production is indeed Is a big problem, this still depends on him.

"By the way, although this is not my job, I still have to be responsible for you: I don't need to emphasize the principle of confidentiality. Remember to emphasize it in place after you go back, lest someone make a mistake on the eve of the celebration banquet!" Wang Feng was serious said.

"Don't worry about this, we have already emphasized it in place, and the comrades in the security department have repeatedly emphasized that we have been familiar with it for a long time." On such an important issue, no one dared to relax their vigilance.
