Technological power starts with upgrading lenses

December of this year is getting closer and closer, and the weather in Dongyang is getting cooler. In addition, it started drizzling today, and the cold wind blew in. Kang Chi, who was waiting at the door of Pangu Base, couldn't help but tremble. A shiver.

"Why don't you go back inside?" Chen Hai keenly noticed Kang Chi's reaction and quickly suggested, "I'll just bring Mr. Cai in."

Kang Chi shook his head: "It's okay, I can still bear it for a while."

The main reason is that I have been staying in the cave for this period of time and it is very warm without turning on the air conditioner. I didn't expect it to be so cold outside.

And Kang Chi insisted on welcoming Cai Yaobin in person. A large part of the reason was because his own airport runway was about to be beaten by someone else...

Just feel,

I couldn't put on the first pussy myself,

It's a bit of a pity.

However, the two did not wait too long. Soon they heard faint roars in the air, and then a small black spot gradually appeared in the white mist directly in front of them. It became larger and smaller. And finally slowly landed on the runway, gliding towards the entrance of Pangu Base.

Looking at the plane getting closer and closer, Kang Chi finally got a rough look at it and couldn't help but ask Chen Hai: "Is this...Yun-12?"

"Well, just look at the size and the propeller."

Kang Chi couldn't help but feel a little disappointed. He originally thought it would be good to watch a fat girl show off her coolness up close, but he didn't expect Mr. Cai to be so low-key and only come over in a super-small transport plane that was almost obsolete.

In fact, Cai Yaobin came here with the luck of 12, which was also intentional.

In addition to keeping a low profile and avoiding waste of resources, another purpose is to "sell miserably".

One is that the equipment is woefully backward.

One is suffering from insufficient funds.

The first one was miserable. Just like before, he wanted Kang Chi to help the military develop some black technology.

The second misfortune is, of course, not to bear the price of this 'surprise' too high...

…

Originally, in order to welcome Cai Yaobin, Kang Chi specially asked people to open all the doors of the Pangu base so that they could fly the plane directly into the tunnel. As a result, a Y-12 slid in, and it felt like a mosquito flying into a small cave...

Cai Yaobin, who was sitting on the plane, couldn't help but be a little stunned after seeing the huge hole in Pangu Base.

Although one of the approval processes for helping Kang Chi build a large secret laboratory passed through his hands, he actually didn't know the specific construction details. Anyway, he only knew that Kang Chi paid for it himself and the military engineering team contributed to the construction. It all depends on Kangchi’s needs.

After getting off the plane, Cai Yaobin first looked around, and then couldn't help but sigh to Kang Chi who came up to him: "Dr. Kang is indeed very wealthy..."

"Nowhere, this place is just a shelf now, and most of the places inside are empty."

Kang Chi smiled and shook hands with Cai Yaobin: "Welcome, Mr. Cai."

Cai Yaobin nodded, and after a few brief greetings, the two took a car and walked into the base.

"It's been almost a year since we last said goodbye to Yanjing. Dr. Kang hasn't contacted me for so long, and suddenly he said he wanted to give me a surprise. It whetted my appetite." Cai Yaobin, who was sitting in the car, couldn't bear it. Zhu opened his mouth and asked, "Can you reveal something first?"

Kang Chi smiled: "There are two surprises this time, but I think you should have roughly guessed one of them."

"lithium battery?"

"Um."

Kang Chi nodded directly, confirming his suspicion.

Because of the technical similarities between sodium batteries and lithium batteries, most people could expect that after his sodium battery was released, lithium battery technology would break through simultaneously.

The difference is only sooner or later.

Cai Yaobin suddenly became excited after hearing this, but having satisfied part of his curiosity, he did not continue to ask further questions.

The group of people soon arrived inside the laboratory.

Looking at the various equipment and instruments densely packed in the laboratory, Cai Yaobin couldn't help but sigh again for Kang Chi's wealth.

You know, this is his personal laboratory!

"This is it."

While Cai Yaobin was still observing the equipment inside, Kang Chi pointed directly at a battery pack on the table and said: "Solid-state lithium-ion battery, energy density 1200wh/kg."

"!!?"

Not only Cai Yaobin, but everyone present was stunned when they heard Kang Chi tell the energy density of this battery in an understatement.

"How...how much energy density?"

"1200wh/kg, one kilogram has 1.2 kilowatt-hours of electricity."

After receiving the confirmation, Cai Yaobin immediately gasped with excitement.

The sodium battery previously released by Kangchi has an energy density of 300wh/kg.

Based on the previous use of similar levels of technology to make sodium batteries and lithium batteries, the performance gap is about 2.5 times. The energy density of the lithium batteries that Kangchi can make with this technology should be around 750wh/kg.

And the 1200wh/kg battery...

I can’t even think about it!

"You...your battery technology...made another breakthrough?"

Even the well-informed Cai Yaobin could not help but tremble in his tone at this moment.

"No." Kang Chi chuckled, "It's just that the sodium batteries released before have left some room."

"..."

Cai Yaobin suddenly became enlightened.

However, if we extrapolate from this, it means that Kangchi’s sodium battery technology can achieve 500wh/kg?

It's absolutely terrifying!

Cai Yaobin couldn't help but look at Kang Chi deeply again.

Although the young man in front of him, who was one round younger than him, seemed ordinary, he felt like an endless mountain.

"What about the cost?"

"Because we need some rare earth materials, it will be a little higher, about 1,200 yuan per kilogram. Can you accept it if I double the price?"

"I can accept it!" Cai Yaobin nodded quickly, "We will make as many as you want!"

In fact, after guessing that the surprise was a lithium battery, Cai Yaobin began to imagine its application prospects.

The first thing that comes to mind is naturally the aircraft carrier's electromagnetic catapult.

As we all know, the power of an aircraft carrier's electromagnetic catapult is very high. For example, the power of a single catapult on the Ford is as high as 30 megawatts.

Therefore, many people feel that if the aircraft carrier is equipped with a nuclear power plant, it will be able to solve the huge power demand of the electromagnetic catapult device on the aircraft carrier.

However, this is not actually the case. Although the electromagnetic catapult has high power, it only has high power at the moment when the aircraft takes off.

Even if nuclear power is installed, it is impossible to keep the nuclear power device at a power that can satisfy electromagnetic ejection, and the fluctuations in the power grid will be very large.

Therefore, batteries can only be used to store energy, and when ejection is needed, supercapacitors can be used to perform ultra-high power instantaneous discharge.

For example, on the USS Ford aircraft carrier, the total power of the four catapults exceeds 120 megawatts. But if averaged, a 2-megawatt diesel generator, plus a supercapacitor and energy storage station can meet the power demand for ejection. .

Supercapacitors can charge a large amount of electric energy in a short period of time and can also release a large amount of electric energy in an instant. However, their electric energy naturally drains quickly and is not suitable for energy storage. It is generally used as an auxiliary component of an energy storage station.

The relationship between batteries and capacitors is a bit like ammunition depots and weapons. One supports logistics and the other supports output.

Therefore, power generation, or conventional power and nuclear power, has never been the key to limiting the performance of electromagnetic catapults, but energy storage.

If you use Kangchi's 1200wh/kg energy density lithium battery as an energy storage station for supercapacitors, due to its high energy density, small size, and high safety, the supercapacitor will no longer have to worry about insufficient power!

This means that the number of aircraft that the aircraft carrier can eject in a short period of time will be greatly increased.

At the same time, a more powerful catapult can also be made.

The improvement in the combat effectiveness of this pair of aircraft carriers cannot even be described using data.

On the ever-changing battlefield, fighter aircraft are fleeting, and the importance of being able to eject carrier-based aircraft in a shorter period of time can be imagined.

Just when Cai Yaobin was still immersed in the joy of supercapacitors, Kang Chi lifted another piece of black cloth.

"This is the second surprise for you, super strong neodymium magnet!"
