Therefore, Liu Cong is going to the laboratory today to use the plan he improved over the past two days in today's experiment.

Liu Cong was very pleased that his efforts were not in vain this time.

After the graphene battery was discharged, Liu Cong used tools to disassemble the battery and found that the graphene inside was well protected by pure metal.

Liu Cong can conclude from this experiment that as long as he makes a slight mistake in the process of fusing metal, the function of the pure metal will be greatly different.

The function Liu Cong wants is the super heat insulation, heat dissipation, and conductivity of pure metal.

With these characteristics, during the charging and discharging process of the battery, the battery will not generate excessive heat, but the graphene will undergo physical transformation and chemical reactions.

This time, Liu Cong made further improvements on the original basis.

He found that on the original basis, reducing the aluminum powder by 0.08 grams and increasing the nickel content by 0.08 grams would lead to better thermal insulation and conductivity.

Liu Cong didn't know the specific principle.

There are so many synthetic substances in nature, and each seemingly simple pure substance can create different mixtures or compounds when combined together.

In short, as long as it works, that's what Liu Cong wants to see.

Seeing that he was getting closer and closer to his expectations, Liu Cong was feeling much better this week.

Even if he doesn't make a breakthrough, he can mass-produce graphene batteries based on today's experimental results alone.

Before that, he still had one important thing waiting for him to do, which was to keep the price of graphene down.

At that moment, Liu Cong picked up the mobile phone in his hand and dialed Gu Xiong's number.

Within a few seconds, a sweet voice came from the other end of the phone.

"Idol, why did you call me today? My brother has gone to a meeting and won't be back until later."

The person who answered the phone was Gu Xiong's sister Gu Hui.

"Okay, I understand. I'll call back later."

"Hey! Don't hang up!"

"Huh? Is there anything else?" Liu Cong asked with some confusion.

"Brother Liu Cong, when will you come over? I miss you!"

When he heard what Gu Hui said, he was shocked.

If his girlfriend Chen Qiong knew about this, even jumping into the Yellow River would not be able to clean it up.

"that…"

"Miss Gu, don't say that. People who don't know may think we have some special relationship."

And how could Gu Hui care so much, "I know, I'll do it again next time!!"

At this time, a burst of hearty laughter came from the other end of the phone, and then the phone was hung up.

"Hey! My charm is so great!"

As he spoke, Liu Cong touched his handsome face with his hand.

When he realized that he had not washed his hands during the experiment, he quickly put his hands back from his face.

Then, he picked up the information he had compiled on the table and began to study the steps of the next experiment.

After a while, the call came back.

Seeing this, Liu Cong answered the phone.

"I'm sorry, Mr. Liu, I was in a meeting just now and my sister had the phone in her hand. I didn't receive it!"

"It's out of the way and won't delay anything."

Hearing what Liu Cong said, Gu Xiong breathed a sigh of relief.

"Mr. Liu, what are you calling for?"

"That's right, I want to ask you about the current price of graphene on the market."

“And how much does it cost to produce graphene materials?”

Facing Liu Cong's question, Gu Xiong gave a direct and accurate answer.

"Mr. Liu, that's it."

"The latest graphene market price update was on September 15, and the price was 535 Chinese coins per gram."

"It's hard to say the cost price, it fluctuates greatly."

"But the specific net cost is controlled in the tens, mainly because the technology is expensive."

"Our company can now control costs within 20 yuan."

Liu Cong still felt that the number Gu Xiong mentioned was too high.

If we calculate it at 20 yuan, the cost of graphene used in a battery is close to 200 yuan.

This is unacceptable to Liu Cong.

"What's the exact cost?"

Seeing Liu Cong asking this, Gu Xiong was silent on the other end of the phone for a long time.

"Is such that."

"Now our refining method has been upgraded. If we really don't trace the mechanical labor cost, it will be about six or seven yuan per gram."

This news is absolutely great news for Liu Cong.

He can't afford graphene that costs hundreds of dollars per gram, but he can still afford graphene that costs a few dollars.

This thing is like a diamond, there are people behind it controlling the market.

As the saying goes, rare things are more expensive. As long as graphene is not mass-produced, its price will continue to be expensive.

The term soft gold is really not called for nothing.

However, if you want to promote your own graphene battery to the market.

First of all, the price must not be too expensive, otherwise no company will order graphene batteries in large quantities.

A small battery costs tens of thousands, and not everyone can afford it.

That's why Liu Cong cares so much about the price of raw materials.

If he could control the cost of a graphene battery the size of a mobile phone battery to more than 100 yuan, he believed that many domestic mobile phone manufacturers would be very happy to purchase it.

Seeing that Liu Cong didn't speak for a long time, Gu Xiong asked on the other end of the phone: "Mr. Liu, are you asking for any big order demand?"

Since Gu Xiong asked this, Liu Cong didn't intend to hide his plan any longer.

"Because I plan to mass-produce graphene batteries, I must bring down the price of graphene batteries."

"Graphene battery?"

"Aren't there many domestic manufacturers? Isn't it just a matter of adding a little graphene powder?"

The graphene battery Gu Xiong refers to is not a true graphene battery in the strict sense.

Domestic manufacturers only sell graphene batteries under the guise of graphene batteries.

In fact, the battery life is not much improved compared to ordinary batteries.

"My graphene battery is not what you think, but a real graphene battery."

"In the true sense?"

"Yes, a real graphene battery!" Liu Cong confirmed to Gu Xiong.

"You mean the kind that can be fully charged in tens of seconds and have a battery life several times that of ordinary batteries?"

"Yes, that's right!"

This time, Gu Xiong didn't speak for a long time on the other end of the phone because he didn't know how to answer Liu Cong's words.

"I know what you are thinking. You don't have to doubt it. Everything I say is true."

"Well, I happen to have time tomorrow, so I will come to Cangtai with a sample of the graphene battery, and I will talk to you about graphene pricing." Liu Cong said to Gu Xiong on the other end of the phone.
