God-level Xueba system

"It seems that everyone understands this knowledge, okay, then I will continue to talk about it!"

Seeing that everyone was silent, Yan Xin erased all the chemical formulas on the blackboard, and picked up the chalk again.

"When the external circuit is disconnected, although there is a potential difference between the two poles, there is no current, and the chemical energy stored in the battery is not converted into electrical energy. When the external circuit is closed, there is current under the action of the potential difference between the two electrodes. Flow through the external circuit. At the same time, inside the battery, since there are no free electrons in the electrolyte, the transfer of charges must be accompanied by the oxidation or reduction reaction of the bipolar active material and the electrolyte interface, as well as the material migration of the reactants and reaction products.”

"Oh? Then what Professor Yan said has nothing to do with my solid electrolyte?" Professor Will wanted to pick a bone in the egg.

"Don't worry, wait until I finish!"

Yan Xin glanced at Will very irritably.

Are these foreign scholars so unqualified?
I'm talking blah blah blah here, but you interrupt me without even raising your hand?
Professor Will made fun of himself and closed his mouth resentfully.

"The transfer of charges in the electrolyte is also completed by the migration of ions. Therefore, the normal charge transfer and material transfer process inside the battery is a necessary condition to ensure the normal output of electric energy. When charging, the process of electricity transfer and mass transfer inside the battery The direction is just opposite to the discharge; the electrode reaction must be reversible to ensure the normal progress of the mass transfer and electricity transfer process in the opposite direction. Therefore, the reversible electrode reaction is a necessary condition for forming a battery."

"Okay! Next, let me talk about the electrolyte problem!"

"It is well known that an electrolyte is a substance that produces a conductive solution when dissolved in a polar solvent. The dissolved electrolyte dissociates into cations and anions, which are uniformly dispersed in the solvent. Electrically, the solution is electrically neutral. If Apply a voltage to this solution, and the cations in the solution are attracted to the electron-rich electrodes, and the anions are attracted to the electron-deficient electrodes. The movement of the anions and cations in the solution in opposite directions creates an electric current."

After Yan Xin finished speaking, he wrote down the common electrolytes on the blackboard.

"Electrolytes include most soluble salts, acids, and bases. Some gases, such as HCl gas, can also act as electrolytes at high temperature or low pressure. Dissolutions such as deoxyribonucleic acid, polypeptides, and polystyrene sulfonates can also produce electrolyte solutions , these polymers containing charged functional groups are called 'polyelectrolytes'. Substances that dissociate into ions in solution have the ability to conduct electricity. Sodium, potassium, chloride, calcium, magnesium and phosphate are also electrolytes."

When Professor Will heard this, his face became a little ugly.

Didn't expect Yan Xin to study the battery field so thoroughly at such a young age?

And Rick didn't believe it, Yan Xin just read a few books!

Based on Yan Xin's current level, publishing an SCI paper should be easy!

However, as a professor of materials at the University of Tennessee, Will will naturally not admit defeat easily.

"As for the solid electrolyte that Professor Will is talking about, although it is quite novel in terms of innovative ideas, the actual thing he made is not very innovative!" Yan Xin said, staring at Will.

"Oh? You mean I have a good idea, but I can't do anything substantial?" Will asked with a frown.

"Yes! Solid electrolytes refer to solid-state substances with ion conductivity used in metallurgy. These substances provide channels for fast migration of ions either because of point defects in the crystal or because of their special structure. At certain temperatures, they have High conductivity. You know, the application range of solid electrolytes is too narrow! Coupled with the large development funds, it is really not worth it! Just imagine, if we, Academician Li, really cooperate with you, which manufacturer is willing to spend money to do this? A solid electrolyte that is rarely used by the public?" Yan Xin spread his hands.

"Then you can't deny my innovation!" Will stood up from the chair at this time.

"Hehe, Professor Will, let me ask you, what is scientific research?" Yan Xin sneered.

"Scientific research? You, a child, actually asked me what scientific research is?" Professor Will said disdainfully.

"Appreciate further details!"

"Listen up! Scientific research means that we use the national funds to develop new products, and then publish them in top journals, so that developers can develop new products and sell them well! In this way, our reputation will be great. Noisy, admired by thousands of people, and can make money without any effort!" Professor Will said with a wave of his hand.

shallow!

All Yan Xin could think of were these two words!

To put it bluntly, isn't it for your own benefit?
"No, you're wrong!" Yan Xin said with a smile.

"wrong?"

"Hehe, this kid really speaks wild words!"

"Interesting!"

All the scholars present except Li Zhentian laughed!

Isn't that the purpose of scientific research?

Is it possible that this kid still thinks that his scientific research has other uses?
"It is said that you are ignorant, but you are also considered to be knowledgeable; you are said to be knowledgeable, but you don't understand such a simple truth? Scientific research is the use of scientific research methods and equipment to understand the inner nature and laws of motion of objective things. A series of activities such as experimentation and trial production. Provide a theoretical basis for the creation and invention of new products and new technologies. Do you understand? Creation and innovation! It is for the country and the people! We do these things to serve the public in the end! It is to protect the environment, to protect the last pure land of our human beings! Not for money, but for reputation!" Yan Xin said loudly.

And Li Zhentian applauded silently behind him.

The other scholars all looked ridiculed.

This kid's head is really watts!

Doing scientific research is to get more honor and money, otherwise who would run around?
This kid actually said that he is so tall, but also serve the country and protect the environment?
joke!

"Son, do you know why your Long Xia's technology lags behind? It's because of your ideological problems! What's the use of your experimental products being practical? Don't they still fail to reach the international stage in the end? Hahahaha!"

After Professor Will finished speaking, he burst out laughing.

"Hehe, different ways do not conspire with each other! But since you look down on Long Xia's scientific research ability so much, today I will let you and me see what advanced Long Xia's scientific research is!"

Yan Xin patted the table, then picked up the chalk.

Professor Will and Professor Rick naturally felt that he had "victory", and looked at Yan Xin indifferently, to see what flowers this kid could come up with, which would shock him.

Yan Xin didn't talk to these superficial people anymore.

These people are as virtuous as the consultant at Cambridge University. What's the use of being highly educated?

Yan Xin began to draw the super battery design of the new energy vehicle on the blackboard, and the group of so-called scholars also began to whisper among themselves.

"This kid really takes himself seriously!"

"That's right, the ones who paint here are not from the art class, are they?"

"I just said that Long Xia should not come this time. There is really no need for cooperation in this country!"

"I think so too!"
