Siheyuan: Open a breakfast shop and make the city cry with envy

Kyoto University

Chen Ze stood on the podium, with hundreds of students and teachers from the School of Mechanical Engineering at Kyoto University sitting below.

Everyone stared at Chen Ze on the podium.

The pen in his hand never stopped moving, carefully recording everything Chen Ze said.

"Although, our Longguo automobile industry is not yet developed!! There is still a big gap between us and some established foreign automakers."

"Right now, in New York, the largest city in the United States, the streets are full of cars! Look at our Dragon Country, where you can only see a few cars on the road occasionally."

"Although our country is still in a backward stage, in the future our Dragon Country will continue to develop and surpass a number of Western countries. It will become one of the countries with the largest number of cars in the world!!"

The students in the audience enjoyed what Chen Ze said as if they were listening to a story.

They have never been abroad, have never been to other countries, and have no idea about the cars running on the streets.

After all, even in Kyoto, the capital of Dragon Country, the streets are not filled with cars.

"Mr. Chen, are the streets of big cities abroad really full of cars?"

In the audience, a girl with short hair couldn't help but raise her hand and speak.

"Of course!!! There are so many small cars abroad!!"

Wow! ! !

There was a lot of discussion in the audience.

In their minds, they cannot imagine what it would be like to have streets full of cars.

"Then...will our country really have streets full of cars in the future?"

The female student asked in a low voice about her vision for the future.

Chen Ze smiled and nodded.

"certainly!!!"

"And in the future, our country's cars will surpass a number of foreign car companies! ! In the world's orders! ! Especially new energy technology! !"

No one has any idea about the new energy technology proposed by Chen Ze.

After all, they only know that Longteng’s new car is equipped with hybrid technology, combining the engine and BRICS batteries.

Together we make cars move forward steadily.

"New energy technology is the battery technology I just mentioned!! Although it is only the 1980s now, I have a hunch that in 40 years, after battery development has stabilized and become popular."

"Hybrid technology will become more popular! Not only that, but pure electric cars will also be available! They can travel hundreds of kilometers with a full charge at home."

"Of course, whether it is a pure electric car or a hybrid car, lithium iron phosphate batteries are indispensable!!"

"I just mentioned lithium iron phosphate batteries. As a new energy product, lithium iron phosphate batteries have the advantages of being more environmentally friendly and energy-efficient!!"

The voice just fell.

Another male student stood up and said excitedly,

"Mr. Chen, can you tell us more about lithium iron phosphate batteries? This is the first time we have heard of it and we have no idea about it!!"

Chen Ze nodded.

Clapped his hands and signaled the male students to sit down.

"In that case, I will now explain to you the lithium iron phosphate battery!! That is our Longteng's gold brick battery!!"

After he finished speaking, all the students in the audience looked more intently at Chen Ze on the podium.

The pen in their hands remained on the paper, waiting for Chen Ze to make his introduction, and then everyone started taking notes.

"Lithium iron phosphate battery is a lithium battery that uses lithium iron phosphate as the positive electrode material!!"

As Chen Ze spoke, he picked up a piece of chalk and wrote the four big words "lithium iron phosphate" on the blackboard behind him.

Then write the corresponding chemical equation below.

【LiFePO?】

"During the charging process of lithium iron phosphate batteries, some lithium ions in them fall off, pass from the positive electrode to the negative electrode through the electrolyte, and embed into the negative electrode carbon material!! At the same time, the positive electrode in the battery will also release electrons, which will reach the negative electrode through the external circuit!! In this way, lithium iron phosphate can maintain a stable chemical reaction!! Achieve balance!! "

"Just now, I explained the charging process."

"Now, let's talk about the discharge process. The discharge process is exactly the opposite of the charging process. The lithium battery is released from the negative electrode, passes through the electrolyte to the positive electrode, and at the same time, the negative electrode releases electrons, which reach the positive electrode through the external circuit to provide energy to the outside world."

While Chen Ze was describing, he used the chalk in his hand to draw a detailed battery sketch on the blackboard.

In the battery sketch, Chen Zebiao outlined its working principle.

As engineering students, they can naturally understand the sketches on the blackboard.

Everyone then started drawing according to the sketch, one by one.

Fearing that he was moving too slowly, Chen Ze erased the blackboard again.

Similarly, all the teachers and students present suddenly understood.

It turns out that lithium iron phosphate battery technology is so simple! !

I thought it was a difficult technical problem.

Because at this time, no country or expert has put forward this view.

So no one is researching in this direction.

After all, the world's oil energy is still in the initial stage of exploitation, and the number of cars on the roads of all countries is less than one twentieth of that of forty years ago.

Of course, there is no need to consider energy conservation and emission reduction.

In an era when oil is plentiful and inexhaustible, everyone is competing to see whose car has more horsepower or whose car has more power.

At this time, Liu Peng, the dean of the School of Mechanical Engineering, also raised his hand curiously and asked Chen Ze a question.

"Mr. Chen, through your explanation, we can see the benefits of batteries, but you also said that the voltage released by this type of battery is more than ten times that of ordinary batteries. So how long can its lifespan be?"

"At home, the three batteries in our flashlight can only last for half a month!!"

All the students present nodded in unison.

Yes!!

The battery of a flashlight can only last for half a month at most, and at best less than a week.

Although Longteng's gold brick battery supports charging and discharging, since it is a battery, it has a lifespan after all! !

“The questions raised by Dean Liu are very good!!”

Chen Ze narrowed his eyes and praised.

"The BRIC battery developed by Longteng has been continuously tested by us. The number of charge and discharge times can reach at least 20,000 times!!!"

hiss! ! !

As soon as these words came out.

The audience was boiling with excitement!!

"Oh my god, did I hear that right?! The battery can be charged and discharged for up to 20,000 times!"

"So horrible!! This is so abnormal!! How can ordinary batteries survive!!"

"Yes! It can charge and discharge, and most importantly, it can provide a higher voltage. This is killing us."

"20,000 times of charge and discharge means the battery won't go bad even if you drive the car to pieces!!!"

"Awesome!! Mr. Chen is really amazing!! It is an honor for our Long Country to have such an amazing person like Mr. Chen!"

"I bow down to you! From now on, Mr. Chen will be my leader in my studies! No, my guide!!"
