Jiang Fan looked at the red numbers displayed on the computer, he pondered repeatedly, and looked at the principle data of the formula several times.

Theoretically, shouldn't there be a problem?

Then, he pulled up all the data. Then let Xu Guangyuan split the lithium iron phosphate power battery.

Start troubleshooting one by one and find out what's wrong!

Lithium iron phosphate power batteries are divided into four core materials.

Cathode materials, anode materials, electrolytes, and separators!

"Senior Sister Xiaoyu, you are responsible for the detection of cathode materials, this is the data!"

"Senior Guangyuan, you are responsible for the testing ...... of anode materials"

"Senior Niu Xu, you are responsible for the data analysis ...... the entire lithium iron phosphate power battery"

Jiang Fan is responsible for the detection of electrolyte!

An hour later, Xia Xiaoyu was the first to complete the test.

"Senior Brother Jiang Fan, there is no problem with the cathode material of lithium iron phosphate power battery, it is the same as the data you gave before the experiment!"

Subsequently, Xu Guangyuan also finished testing with an instrument!

"Senior Brother Jiang Fan, there's no problem on my side!"

When Jiang Fan finished testing the electrolyte of lithium iron phosphate power battery, he found that there was no discrepancy with the expected data.

Now there is no test of the battery separator!

If a problem is detected, they can target the problem and fix it.

I'm afraid that if I can't find the problem, then it's troublesome!

Subsequently, Jiang Fan and the three of them began to test the separator of the battery together!

For the separator of lithium iron phosphate power battery, Jiang Fan designed a porous polymer membrane.

It refers to the lithium iron phosphate battery separator with uniform pore distribution prepared by mechanical methods, thermo-induced phase separation method, immersion precipitation method and other methods.

After another hour, Jiang Fan and they did not detect anything unusual about the porous polymer membrane!

Sure enough, the worst happened!

Just when the three of them were confused, Niu Xu had already compared all the data and found out the problem!

"Senior Brother Jiang Fan, the data anomaly has been found!"

When Jiang Fan heard this, he was immediately excited, and hurriedly said!

"Senior, what's the problem?"

"You see, the anomalous data originates from the battery's separator!"

"But we've already tested the battery's separator and there are no problems?" Xu Guangyuan said!

At this time, Xia Xiaoyu said after thinking for a moment.

"You say, is it possible that we were wrong to use porous polymer membranes in the first place!"

After Jiang Fan heard this, he fell into thought, there is really such a possibility.

After all, his understanding of lithium iron phosphate power batteries is only derived from the technical understanding of the earth in the previous life!

Moreover, his previous main research was nanomaterials, and although he had been exposed to some batteries, it was not his main research direction!

Jiang Fan remembered at this time that there is another material for the separator of the battery, which is the inorganic composite film.

It is a lithium iron phosphate battery separator obtained by using inorganic nanoparticles and high polymer compounding.

The technical difficulty of this separator lies in nanoparticles, and for him, who previously focused on nanotechnology, there is no such problem!

"Senior Brother Jiang Fan, the data shows that there is a problem with the battery separator, but we can't detect it, what can we do?" Xia Xiaoyu asked!

"Let's change a battery separator, it should be solved!" Jiang Fan said!

"A different kind of battery separator?"

Xu Guangyuan said in surprise that it is not easy to research every technology of the battery!

Changing a battery separator, there is no technical principle, it is completely by exploration, at least half a year!

"Senior Brother Jiang Fan, changing a battery separator, it's easy to say, if you really do it, it's not that simple!"

Jiang Fan knew what the difficulty was when Xu Guangyuan said!

"Give me two hours, and I'll make the technical principle data!" Jiang Fan said lightly!

Xu Guangyuan laughed directly, a new technical principle, Jiang Fan said that he could make it in two hours!

It's a funny joke he's heard.

Even if Long Lao was here, in the face of a new type of technology, he didn't dare to say that he could make it in two hours!

"Senior Brother Jiang Fan, I feel that we should study more deeply on the porous polymer membrane, maybe we can solve the problem!"

Xia Xiaoyu said, to be honest, she didn't believe that Jiang Fan had developed a new type of diaphragm in such a short period of time!

If you can't research it, you will waste a lot of time and effort.

If so, then they don't have to study the existing diaphragm technology directly. The success rate is even greater!

Jiang Fan saw that Xu Guangyuan and Xia Xiaoyu had no confidence in him, so he said to them!

"Senior, senior, give me two hours, if I can't make a new type of diaphragm material formula principle, let's study the original diaphragm technology together!"

Since Jiang Fan said so, Xia Xiaoyu and Xu Guangyuan couldn't say anything more.

After all, when Long Lao left, he explained that Jiang Fan was the person in charge of researching lithium iron phosphate power batteries!

If they have any objections, they must obey Jiang Fan's opinions.

After Jiang Fan finished speaking, he devoted himself to the principle of making inorganic composite membrane formulas!

Xia Xiaoyu looked at the serious Jiang Fan, and there was still some expectation in his heart that he could study it!

So that they can solve the problem with the diaphragm!

"What are you two in a daze, while Senior Brother Jiang Fan is developing new materials, let's hurry up and rest for a while! Otherwise, the principle of the formula of the new material will be made, and we will be busy again! ”

"Xiaoyu, you don't think Jiang Fan can really study it, right?"

"Why not believe it? He can make a research plan for lithium iron phosphate power battery, what is a small battery separator material! ”

Xia Xiaoyu said it easily, but she still knew in her heart that it was not easy to really study it.

Anyway, she's been working 18 hours straight and she's too sleepy now.

Taking advantage of the fact that Senior Brother Jiang Fan is busy this week, her most knowing choice is to get a good night's sleep!

Xu Guangyuan and Niu Xu saw Xia Xiaoyu lying on a simple bed and falling asleep!

They looked at Jiang Fan again and decided to rest for a while!

……

In a private room in the cafeteria of the classroom of the University of Dragons.

Two middle-aged people are talking and laughing about their high school days!

One of them is Professor Wan of the materials major of Long University of Science and Technology!

One is Wang Chuanfu, the boss of BYD.

After a few glasses of wine, Wang Chuanfu said in a deep tone!

"Old classmate, to be honest, I came to you this time, I ran into trouble that I couldn't solve!"

"Chuanfu, you are the boss of a large company, and there are other things you can't solve?"

"It's extraordinary, Tesla's announcement of a 30% increase in battery performance, have you heard?"

"I heard!"

"I'm here for this, we, BYD New Energy Automobile Company, ......"

Wang Chuanfu told Professor Wan the reason for the incident, and told him the purpose of looking for him!

After listening to this, Professor Wan did not expect that the matter would be so serious.

At this time, he suddenly thought of Long Lao of Long Keda, who was researching mecha energy batteries, and he didn't know if there was a breakthrough!

"Chuanfu, there is really an academician in our school who is researching batteries!"

"Really, great, as long as he can solve the battery problem, I am willing to pay 1 billion to invite him out of the mountain!"
