When the 'Efficient Energy Reserve' option is unlocked.

A prompt appears immediately: ‘High Efficiency Energy Reserve’ is successfully unlocked and 0% is currently mastered.

Then, Zhang Zhai learned what this so-called high-efficiency energy reserve was.

His guess was correct, this was new battery technology.

But one thing he didn't expect was that there was not just one new battery technology, but three.

These three types are, respectively,

The first one is graphene batteries, which have been hotly speculated in recent years. There are many related concept stocks on the stock market.

The second type, which ordinary people may not be familiar with, but many people still know, is the solid lithium-ion battery.

As we all know, the current common batteries are liquid lithium-ion batteries, but unlike current batteries, solid-state lithium-ion batteries have high energy density, can hold more power in the same volume, and are safer.

As far as Zhang Zhai knows, many companies are studying solid-state lithium-ion batteries, including Rotten Apple in the United States, and it is said that they are almost in mass production.

It can be said that this battery technology is very close to real technology.

However, compared to real-life technology, Zhang Zhai's black-tech solid-state lithium-ion battery has a higher battery capacity, is safer, and is more resistant to wear and tear.

As for this third type of battery, even Zhang Zhai has never heard of it, namely nanowire solar cells and nanowire batteries.

Are you sure these are not two types of batteries?

However, seeing that they are also nanowire batteries, they seem to be classified into the same category.

But what do we mean by nanowires?

After receiving some information, Zhang Zhai had a vague understanding of nanowires.

The so-called nanowire solar cells use semiconductor nanowires instead of silicon wafers to manufacture solar cells.

The advantage is that it is cheap.

This kind of solar cell is different from traditional solar cells in that its materials are cheap and its ability to aggregate and separate charges is also very strong.

Nanowire batteries are similar, using metal nanowires instead of traditional lithium ions to create metal nanowire batteries.

Its characteristic is that it is resistant to loss, particularly resistant to loss, and very resistant to loss.

In this regard, it is probably hundreds of times more powerful than traditional lithium-ion batteries.

So why, although it is so popular, has it not been used on a large scale?

Zhang Zhai really lacks understanding of the term nanowire.

"A1, search for information related to nanowire batteries." Zhang Zhai asked A1 to help him find information.

"Okay, Father, I have already selected it for you." A1 immediately popped up the holographic screen, allowing Zhang Zhai to see the information she had selected.

"Um."

Zhang Zhai frowned and read page after page.

After a few minutes, Zhang Zhai finally figured out the reason.

"So that's the case, no wonder..." Zhang Zhai shook his head.

It turns out that this technology also exists in reality, but it was proposed not long ago.

Compared with traditional solar cells, which are expensive and prone to loss of traditional lithium-ion batteries, nanowires have obvious advantages: they are loss-resistant, cheap, and have a very large power capacity.

But there is also a fatal problem that masks its advantages. Compared with traditional solar cells, nanowire solar cells have a very low conversion rate.

Originally, the energy conversion rate of traditional solar cells was low enough, but the conversion rate of nanowire solar cells was even lower, which almost made them lose their practical value.

What about nanowire batteries? Although they have promising prospects and are a perfect battery, there is still a long way to go before they can be put into practical use. They are purely conceptual products.

So, can the technology obtained by Zhang Zhai solve these problems?

"It solves the problem of conversion rate, making the conversion rate of nanowire solar cells even higher than that of traditional solar cells. It also provides a manufacturing plan for metal nanowire cells..." Zhang Zhai murmured, thinking.

Although he has not fully mastered the nanowire battery technology in his mind, Zhang Zhai can still see clearly the extent to which it can be achieved in the end.

This seems to solve all the problems of nanowire batteries?

But...what a pity.

Zhang Zhai shook his head, "I asked how could you be so generous, giving three battery technologies at once.

It turns out that only one kind was given."

“The graphene battery manufacturing technology is available, but the key to the graphene battery is the technology to extract graphene.

There are plans for making nanowire batteries, but there is no technology to make that special kind of nanowires...

This is crazy..."

Zhang Zhai cursed in a low voice, "Isn't this a lie?"

"Isn't this just unnecessary when you take off your pants and fart?

What’s the point of just emasculating part of this black technology?”

This is equivalent to giving you the technology to make a spaceship and you understand it. The result tells you that the materials for making a spaceship are only available on Mars.

So this technology can only be used for viewing?

This is really, how can I put it?

Unable to complain.

"It seems that solid-state lithium-ion batteries can be produced?"

"Well, at least this high-efficiency energy storage technology is not completely meaningless."

Zhang Zhai could only accept it. After all, if he wanted to complain about the system, he had no place to complain.

When the guy next door, Shikong, bought the system for him and sent it to him, he didn’t leave an invoice, so there was no place to complain.

"A1, find me all the books, cutting-edge papers and information on batteries, preferably on solid-state batteries."

"Okay, Father."

Regarding Zhang Zhai's instructions, a1 did not hesitate to come back.

"Father, these are information that can be obtained from public channels. Do we need to search more deeply?" a1 asked.

"No need." Zhang Zhai shook his head, then pulled out all the information found by a1 and started reading.

With artificial intelligence, finding information is much easier.

I just don’t know. Some people know that this is how he uses a1. I wonder if they want to strangle him to death.

Ten minutes later, Zhang Zhai felt his neck was a little sore.

"Although the reading experience on the holographic screen is not bad, I feel a little uncomfortable," Zhang Zhai thought and shook his head, "Forget it, let's go to the library."

Zhang Zhai was about to get up,

"Bang!"

A dull sound sounded.

It seemed like something hit the door of Zhang Zhai's dormitory.

Zhang Zhai was a little confused, what was this sound?

I was about to open the door and take a look.

"Bang!"

There was another dull sound, which seemed to hit the wall next to the door.

Immediately afterwards, there was a slightly crisp sound.

"boom!"

Hearing this voice, Zhang Zhai was stunned for a moment, then his body tensed up and his eyes became sharp.

He quickly leaned his body against the bed, avoiding standing directly opposite the window and door.

because,

That sound just now was clearly a gunshot!

This sound went away just as quickly as it came.

It seems like nothing happened.

Zhang Zhai frowned tightly, feeling a little confused.

Then carefully, move behind the door.

…

Opened the door.

What came into view was a scene like this.

Two people fell to the ground, and one of them was lying next to the door of the dormitory, holding a dagger in his hand. The dagger was still stained with blood, and there was blood on his back. In association with the previous gunshots, he should have been shot.

There was another person, right next to this person, lying on his back, face upward, eyes wide open, motionless, and seemed to be dead.

There was blood on his chest, and the flesh was bruised. It must have been a fatal injury.

Looking at the dagger held tightly by the lying man, perhaps his death was related to the lying man.

Not only were these two dead people, there were three living people in the corridor at this time.

They were dressed normally, but they had guns in their hands.
