Wang Fan's return.

It caused a fierce discussion in the research group.

After all, no matter what they say, in their eyes, Wang Fan jumped off the fifth floor two months ago and was sent to the hospital on the spot.

At that time, the students who were a little closer could hear the sound of a heavy object falling down.

However, what is going on now?

Jumping around and looking like nothing has to do to return to the research group.

"I'll go, did you see it, Wang Fan is back, he is back......... What's going on, don't you tell me, this is what it looks like to jump from the fifth floor? ”

"You shouldn't be lying to me."

"Bullying me for not being there at the time?"

Seeing that Wang Fan was carrying a satchel, as if nothing had happened, a member of the research group looked up and asked in a daze.

Now he has one thing to say, and he is very skeptical of life.

"It can't ........."

"I saw it with my own eyes, so I promise I didn't talk nonsense."

"They were all sent directly to the rescue."

"It's a big deal."

"If it weren't for the school to suppress ........."

Someone immediately retorted.

"Then look at what the situation is, it's still a hundred days to break your muscles and bones."

"Just look at it........."

However, as soon as the words fell, when he turned his head and saw Wang Fan standing at the door, his eyes were straight, and his small eyes revealed a big shock.

…………

Listen to the words in your ears,

Wang Fan didn't pay much attention to it, and after saying hello to a few friends who were more familiar with him, he pushed away his laboratory and sat down, and began to sort out some of the data before the experimental verification.

After a while,

The door slammed open,

A sweaty little fat man with a swollen face appeared in front of Wang Fan.

"No, Wang Fan, what's your situation?"

"Why was you discharged so quickly?"

"Stay a few more days?"

This is the best friend of the predecessor, and it is also the one who spoke out for Wang Fan most actively after his accident.

With a sweaty face, I didn't have to think about it, and after knowing the news of his return, I trotted all the way over.

"Why, you still want me to stay in the hospital longer."

"Just don't expect me to be good?"

Wang Fan looked at the little fat man and asked rhetorically.

"No, no, no, you know I didn't mean that."

When the little fat man heard this, he immediately noticed that there was an ambiguity in what he said, and immediately became anxious, and hurriedly added:

"I mean, you were so badly injured at the time, you had to rest well anyway, how did you come back so quickly, no matter what you have to deal with, or your body is the most important, but don't leave any sequelae."

"I've heard that you've made a lot of trouble here, and the hospital and school have taken measures, so you don't have to worry about your graduation design and graduation thesis at all, you can just lie down."

The little fat man Tao Wei said.

I was afraid that Wang Fan would come back early regardless of his health because of the graduation thesis and graduation project at hand.

"It's fine."

"I'm fully recovered, don't worry."

"It's really fake, it's only been a few days, huh?"

"Then there is still a vacation, I haven't fully recovered, can the hospital let me come back?"

Wang Fan spread his hands and said angrily: "Besides, if I don't fully recover, the Queen Mother will definitely not be able to release her, so I can't live in a hospital bed for 24 hours." ”

"Oh, that's right."

"Makes sense."

Listening to Wang Fan's words, Tao Wei nodded, and then reacted.

"It's okay."

"That's right, but don't think about it anymore, there is nothing in this world that you can't get over."

"What's next?"

Tao Wei then asked.

Wang Fan pointed to the pile of documents in front of him: "Finish this thing first." ”

"Are you going to continue?"

"Isn't there an error in the experimental data?"

"This back and forth will take more than twice as long."

Tao Wei said worriedly.

Wang Fan waved his hand and didn't say anything:

"It's just some data verification, and in the two months I've been lying in the hospital bed, I've not been idle there every day, and I haven't done anything."

"There's a new way of thinking."

The two chatted for a while, and after Tao Wei made sure that Wang Fan had no problems, he left with confidence and went to work on his own papers.

Wang Fan closed the door, turned his mobile phone to silent, entered his own retreat mode, and began the next important data verification.

Piles of documents, accompanied by bursts of buzzing sounds, erupted on the printer, there was system information about silicon carbon anode materials, and after a while, they were stacked there, waiting for Wang Fan's review.

"Through the blending of silicon-based materials and graphene and other highly crystalline carbons that can be reversibly electrochemically intercalated by Li+, the blending ratio and size of the materials can be further controlled, and even nano-scale, which should effectively suppress the huge volume changes of silicon-based materials in the process of charging and discharging."

"At the same time, it is also possible to design a high-safety functional separator based on silicon carbon anode material based on the existing ............"

Wang Fan was flipping through the information and data, and at the same time, he was talking to himself.

meanwhile

I also started making phone calls to buy the equipment I needed next.

Fortunately, the family has a strong foundation, otherwise, it really can't withstand Wang Fan's toss.

The predecessor was able to produce so much useful data that it almost stepped into the door of the energy system with one kick in the door.

There is one thing to say, it is also based on a strong material foundation, if the experiment does not work once, then twice, if it does not work twice, then three times, as long as the direction is correct, sooner or later it can be done.

What?

Materials, the school did not give approval?

Then do it yourself.

After spending nearly a million dollars before and after emptying Wang Fan's own pocket, all kinds of instruments and consumables needed for the subsequent experimental data verification were barely in place.

From the beginning of May to the middle of June, for about 50 days, Wang Fan ate, drank and lazard in the laboratory, except for the evening graduation and went back to the dormitory to rest, it can be said that he lived in the laboratory.

For the past fifty days,

Basically troubleshooting the previous mistakes.

After filtering out an erroneous piece of data.

Everything is very clear.

“OK！”

"I've been busy until now, and the first experimental material has come out."

Wang Fan, who was in front of the test bench, stared at the newly formed silicon carbon anode material in front of him, slapped his thigh violently, and was so excited that he almost shouted.

"Next, it's time to test the material data."

After the excitement, Wang Fan regained his composure, and made ten copies of silicon carbon anode materials for the magic cannon, and then verified the repeated data hundreds of times.

"The first data verification, the energy density is 950mAh/g."

"Second data verification: energy density 1590mAh/g."

"3rd Data Verification: Energy Density 2450mAh/g"
