I can see the commodity price curve

Zhang Yue put the battery into his pocket.

It's summer now, and he's wearing a short-sleeved shirt and ultra-thin trousers.

When I put the battery in my trousers, I instantly felt an uncomfortable bloating sensation.

He stood up and took two steps. With every step he took, the pocket containing the batteries would subconsciously fall down.

Fortunately, his pants were tied with a belt.

If they are elastic pants, if you run a few steps quickly, the pants might fall down.

After taking the battery out of his pocket, Zhang Yue put the phone back in.

Zhang Yue’s mobile phone is a domestically produced high-end model. Due to the high quality of the materials used, it is not light in itself and is actually about the same weight as the battery.

But he didn't feel much after putting it in his pocket. After thinking about it for a while, he understood the reason.

The reason why I feel comfortable is that my phone is very thin.

Although it feels a bit heavy when put in your pocket, it is acceptable.

In fact, because this phone uses the latest super explosion-proof glass, it is heavier than 99% of the mobile phones on the market.

Therefore, the mobile phones on the market are definitely lighter than his phone, and you won’t feel it when you put it in your pocket.

Thinking of this, Zhang Yue felt a little regretful.

He thinks the idea of ​​increasing the thickness of the phone to increase the battery capacity is actually a really good idea.

As if sensing his intention, Guo Ziliang said, “Boss, you don’t have to worry about it.

This idea doesn’t work, let’s try another one.

For example, we can mass-produce this thin battery. "

He said it with confidence.

If it were in the past, Guo Ziliang would definitely worry about what Guangming Electronics Factory should produce.

But now it’s different. Yuehui Lithium Battery Co., Ltd. already belongs to Zhang Yue, including all battery-related patents.

So Zhang Yue took over all the lithium battery orders except those from Fruit and Six Star.

If Zhang Yue is willing, he can even revoke the authorization for Fruit and Six Stars.

In that way, Zhang Yue would become the world's king of lithium batteries, and all merchants who needed this kind of battery would have to look to him for approval.

What is a monopoly?

Monopoly, can customize the price of goods at will.

Monopoly, especially monopoly in the intermediate industrial chain, can even determine the life or death of a company.

If Zhang Yue refuses to supply a mobile phone company, the company will have to use lithium batteries produced by other companies.

Lithium batteries produced by other companies are either not durable or have safety hazards because many patents are monopolized by Yuehui.

In a year at most, this mobile phone company will lose consumers' trust and go out of business due to its battery quality.

For example, why did Four Star withdraw from the Chinese market back then?
It's because of the battery problem.

Zhang Yue looked at him in surprise: "You mean to produce this kind of ultra-thin battery? Are you kidding?"

Guo Ziliang nodded: "Of course I'm not kidding, although this ultra-thin battery is only a semi-finished product, it has more uses than the ultra-thick battery.

For example, the storage capacity of this ultra-thin battery is one thousand mAh. If we put four pieces side by side, would it be four thousand mAh?

This is enough to meet the power needs of a mobile phone.

So can we make a super-thin phone with a super-large screen?"

Zhang Yue was stunned for a moment, then suddenly raised his head and said, "Isn't this just a tablet?

Of course, unlike ordinary tablets, it is an ultra-thin tablet.

But this tablet phone doesn’t seem to be much different from a regular tablet, right? "

"This..." Guo Ziliang blushed. Zhang Yue was right. It seemed that there was not much difference.

Unexpectedly, Wu Minghai suddenly slapped his forehead and looked at Guo Ziliang with surprise: "Director Guo, your idea is absolutely great!"

Guo Ziliang was stunned: "Absolutely? Manager Wu, please stop joking, I was just saying it casually."

When Zhang Yue reminded him that his idea was a tablet, Guo Ziliang came back to his senses.

That’s right, my creativity is indeed not that good.

Although ultra-thin tablets look cool in the hand and are more convenient to carry, they have a fatal problem: they are too big.

The reason why mobile phones are developing full-screen instead of continuing to increase their size is that current mobile phones have already reached the limit of what they can do while being easy to carry.

Any bigger and it would become a burden.

Wu Minghai smiled. He suddenly turned around and walked to a cabinet, then took out a piece of paper.

No, this is not paper, but a piece of plastic, a bit like the chest X-rays used in hospitals.

He handed it to Guo Ziliang: "Take a look at this."

Guo Ziliang took it in his hand in surprise, and looked at it for a long time, his expression full of confusion: "What is this?"

“Foldable screen!”

"Ah?" Guo Ziliang was a little confused. It's not that he couldn't understand the words "foldable screen", but this technology seemed a bit outrageous!

Wu Minghai smiled slightly, took the screen in his hand, and turned it on.

The screen lit up.

Of course, due to the lack of other components, although it lit up, the screen was only blue.

Under Guo Ziliang's incredulous gaze, Wu Minghai folded the screen in his hand like paper.

And the degree of folding is one hundred and eighty degrees.

When it unfolded the screen, the blue screen was still a blue screen and there was no problem.

Of course, if you look closely, you can still see faint traces of the screen being folded.

But it is unavoidable.

After all, even the plastic sheet that is the least likely to be folded will still leave marks after being folded.

This crease will slowly disappear due to the force after the screen flashes.

Looking at Guo Ziliang, Wu Minghai smiled and said, "Do you understand now?"

Guo Ziliang nodded in understanding. If this folding screen is used together with this ultra-thin lithium battery, it is entirely possible to design a folding mobile phone.

Folding phones increase the size of the screen and are inconvenient to carry, which is simply perfect.

He took the folding screen and started to fiddle with it. The simplest foldable screen phone is two-fold.

But after the two-fold phone is unfolded, its screen is still not big enough. It would be great if it could be folded once and then folded once more to become four folds.

But Guo Ziliang soon discovered that this approach did not work.

Because according to my own ideas, one corner of this soft screen needs to be folded twice.

This is not a big problem for the screen itself, but in addition to adding a battery, various components need to be added behind the screen, especially the phone frame.

So the second folding cannot be done at all.

and many more!

Guo Ziliang suddenly remembered the memorials used by ancient emperors.

Because all the creases of this kind of memorial are parallel lines and the folding angle is exactly opposite each time, even if a mobile phone frame is added at the back, it can still be folded repeatedly as long as the design is good.

He told Wu Minghai his idea, and his eyes lit up: "Zouzhang mobile phone? What a great idea!
Let me think about it. Based on the thickness of the battery and the volume of other components of the phone, we can stack it five times. Five times, it is almost the same as a laptop. It would be really cool to watch movies on this screen. "

The way he looked at Guo Ziliang became more and more different.

In fact, when Wu Minghai first met Zhang Yue, he was still very proud.

In his opinion, Zhang Yue was just a local tycoon who was stupid and had a lot of money.

Otherwise, the other party would not be so foolish as to spend hundreds of billions to buy Yuehui lithium battery.

But now, he knows he was wrong.

How could someone who could come up with a feasible proposal in just a short moment be a mediocre person?
He said to Zhang Yue: "Boss, are you planning to develop this kind of folding screen?

If you are interested, I can try to see if I can design a prototype."

Zhang Yue smiled and said, "Sure, go ahead and research, don't be afraid of spending money.

By the way, we should also develop the cell phones with thicker batteries. "

"Ah, are you also developing thickened batteries?" Wu Minghai's face was full of confusion.

This plan has been rejected. If we continue to study it, it will be a waste of effort.

Zhang Yue said: "R&D is R&D, as for whether it can be put on the market, we will see when the time comes.

Moreover, it is just a subjective conjecture that thickening lithium batteries is not desirable. How can you be sure that no one likes this thing?

I personally think we can produce 5,000 to 10,000 units and put them on the market to meet the special needs of certain special groups.”

Hearing Zhang Yue's words, Wu Minghai nodded.

As a scientific researcher, he actually prefers to develop all kinds of inspirations and creative ideas.

It’s just that Yuehui Lithium Battery is a private company, and profits are the most important thing, and we have to be responsible for the company.

This constrained his thinking.

Now Zhang Yue doesn't mind, so if I object, I'd be crazy.

Zhang Yue smiled and said, “Okay, that’s all the things that need to be done. Lao Guo will contact you when it comes to the specific details.

Do you have any needs? If so, please let me know. Whether it is funding or personnel, I can find a way to help you solve it. "

Although the purchase of Yuehui lithium batteries was for Guangming Electronics Factory, Yuehui is also Zhang Yue’s company.

As a responsible boss, Zhang Yue never favors one over another.

Wu Minghai was stunned, then shook his head: "The staff and funds are sufficient for now, there is no need to increase them."

Although Boss Zhao is aloof, he knows very well what the foundation of Yuehui Lithium Battery's survival is.

So he will cut back on other parts, except for the R&D department.

Not only that, as long as Wu Minghai has any requests, Boss Zhao will do his best to satisfy them.

Yuehui Lithium Battery’s success today is certainly due to Wu Minghai’s strong ability, but it is also inseparable from the strong support of Boss Zhao.

Zhang Yue nodded and was about to leave when Wu Minghai suddenly said, "Boss Zhang, how about I take you to visit our S Department?"

Zhang Yue was stunned, a little confused: "S Department? What is this?"

Wu Minghai said: "Department S is the most core and confidential department of Yuehui Lithium Battery R&D Department. All the company's most advanced R&D results come from there.

Normally, except for core R&D personnel and Boss Zhao, ordinary people are absolutely not allowed to enter.”

"Really?" Zhang Yue instantly became interested after hearing the other party speak so mysteriously, "Let's go and take a look."

According to Zhang Yue, since Department S is so mysterious, it should be in a basement or something.

In fact, this is not the case. The S R&D department of Yuehui Lithium Battery is on the first floor of Office Building No. 3, and people often pass by on the roadside, so it can be said that there is no privacy at all.

He followed Wu Minghai in and was suddenly stunned.

The next moment, he quickly retreated.

Looking at the glass on the window of the room, Zhang Yue understood instantly.

The glass used in S R&D department is a very special film glass.

When you look at this kind of glass from the outside, you can only see that the room is dark and you can't see anything clearly.

But looking from the inside out, you can see it clearly.

The key is that this kind of glass does not block the sunlight at all. People in the room can feel the sunlight shining on their bodies very comfortably.

Placing the laboratory on the first floor may seem exposed, but it is true that the most dangerous place is the safest place.

Not to mention others, even Zhang Yue didn't expect that this was Yuehui Lithium Battery's most confidential laboratory.

There were six people busy in the room. They were wearing white coats and white masks.

When Wu Minghai came in, no one looked up, but continued to do their own thing.

Wu Minghai introduced to Zhang Yue: "There are currently three projects here.

The first project is how to improve the energy storage efficiency of lithium batteries without changing their volume.

The second project studies wireless charging.

Of course, although the current wireless charging technology has matured to some extent, it is still far from its ultimate form.

Because a medium is required when charging.

When wireless charging can achieve virtual connection like Bluetooth, it will be considered the final destination.

As for the third technology, it is the most popular graphene at present.

Graphene is currently the material most likely to enable humans to achieve room-temperature superconducting technology, and it is very worthy of further exploration.

Unfortunately, this technology is still in its infancy.

Although there are some results, they are barely scratching the surface.”

Guo Ziliang couldn't help but say, "Even if graphene superconductivity is achieved, it doesn't seem to have much effect on the battery, right?"

Seeing Wu Minghai looking at him in surprise, he quickly said, "Don't get me wrong, I don't mean to question you, it's just that with my knowledge, there are some questions that I can't understand.

I graduated from junior high school and didn't even go to high school, let alone college.

Even the little knowledge I learned in middle school was returned to the teacher.”

Wu Minghai smiled and said: "This is very simple to understand, yes, graphene superconductivity is indeed not important for the battery itself.

However, the biggest feature of superconductivity is that it reduces energy loss and improves energy utilization.

Take the mobile phone battery for example. Every time it is charged and discharged, the energy inside is either used by the mobile phone or lost as heat.

Do you know how much heat is lost?
At least 50 percent, and some even reach 70 percent."

Guo Ziliang was stunned: "So many?"

“Of course, for example, when you use a mobile phone, as long as you increase the brightness to more than 50%, you will feel that the phone is getting hot.

Some phones don’t get hot, but that doesn’t mean the battery utilization is high. Rather, it means that the heat is dissipated by the phone’s powerful cooling system.”

Guo Ziliang nodded: "So what you mean is that if graphene can really be used, even if the storage capacity of the mobile phone lithium battery remains unchanged, it can still be extended by at least twice?"

Wu Sihai smiled and said, "That's right. In fact, it is not necessary to completely reach the superconducting state. As long as the heat loss can be reduced to a certain extent, the goal has been achieved."

While the two were chatting, Zhang Yue looked around curiously.

Suddenly, he looked at a piece of battery material in a researcher's hand, and a line of words suddenly appeared in his eyes.
