Chapter 223 Terrifying Energy Density
Chapter 223 Terrifying Energy Density
As December approaches, the weather in Dongyang gradually turns cooler. In addition, it drizzles today, and the cold wind blows, making Kang Chi, who is waiting at the door of Pangu Base, shiver.
”Why don’t you go back inside?” Chen Hai keenly noticed Kang Chi’s reaction and quickly suggested, “I’ll bring Mr. Cai in.”
Kang Chi shook his head: “It’s okay, I can still hold on for a while.”
The main reason is that I have been staying in the cave for a long time, and it is 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 big part of the reason is that his own airport runway is about to be taken down by others…
It feels a bit strange and regrettable that I couldn’t install the first one myself.
However, the two did not wait too long. Soon, they heard a faint roar in the air. Then, a small black dot gradually emerged in the white fog in front of them. It grew larger and lower, and finally landed slowly on the runway and taxied towards the entrance of Pangu Base.
Looking at the plane getting closer and closer, Kang Chi finally saw its appearance roughly, and couldn’t help asking Chen Hai: “Is this… Yun-12?”
”Well, you can tell by the size and propeller.”
Kang Chi couldn’t help but feel a little disappointed. He thought it would be nice to watch the fat girl show off at a close distance, but he didn’t expect President Cai to be so low-key and only took a super small transport plane that was almost eliminated.
In fact, Cai Yaobin’s decision to take Yun-12 was also intentional.
In addition to keeping a low profile and avoiding waste of resources, another purpose was to “sell misery”.
One is the poor equipment,
The other is the poor funding,
The first one is the same as before, they want Kang Chi to help their military with some black technology,
The second one is naturally to bear the price of this “surprise” not too high…
…
Originally, in order to welcome Cai Yaobin, Kang Chi specially asked people to open all the gates of Pangu Base so that they could drive 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…
And Cai Yaobin, who was sitting on the plane, couldn’t help but be a little dumbfounded after seeing the huge hole in Pangu Base.
Although one of the approval links for helping Kang Chi build a large secret laboratory went through his hands, he didn’t know the specific construction details. Anyway, he only knew that Kang Chi paid for it himself and the military engineering team worked hard. What kind of construction it would be depends on Kang Chi’s needs.
After getting off the plane, Cai Yaobin first looked around, and then couldn’t help but sighed to Kang Chi who came up to him: “Dr. Kang is really rich…”
”No, no, this place is just an empty shell 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 simple greetings, the two took a car to the base.
”It’s been almost a year since we last parted in Yanjing. Dr. Kang hasn’t contacted me for so long, and suddenly said he wanted to give me a surprise, which really whetted my appetite.” Cai Yaobin, who was sitting in the car, couldn’t help but ask, “Can you reveal something first?”
Kang Chi smiled: “There are two surprises this time, but I guess you should have roughly guessed one of them.”
”Lithium battery?”
”Yes.”
Kang Chi nodded directly, confirming his guess.
Because of the technical similarities between sodium batteries and lithium batteries, when his sodium battery was released, lithium battery technology would also break through at the same time, which was also expected by most people.
The only difference was the time.
After hearing this, Cai Yaobin was also a little excited, but he did not continue to ask questions after satisfying some of his curiosity.
The group soon came to the inside of the laboratory.
Looking at the various equipment and instruments densely packed in the laboratory, Cai Yaobin could not help but sigh again for Kang Chi’s wealth.
You know, this is his personal laboratory!
”This is it.”
Just when Cai Yaobin was still observing the equipment inside, Kang Chi pointed directly to a battery pack on the table and said: “Solid-state lithium-ion battery, energy density 1200wh/kg.” ”! !?”
Not only Cai Yaobin, everyone present heard Kang ChiAfter casually mentioning the energy density of this battery, everyone was stunned.
”How much energy density?”
”1200wh/kg, 1.2 kWh per kilogram.”
After getting the confirmation, Cai Yaobin was so excited that he gasped.
The sodium battery released by Kangchi before had an energy density of 300wh/kg.
According to the previous use of similar technology to make sodium batteries and lithium batteries, the performance gap is about 2.5 times. The lithium battery that Kangchi can make with this technology should have an energy density of about 750wh/kg.
And a 1200wh/kg battery…
I can’t even think about it!
”You…your battery technology…has made another breakthrough?”
Even the knowledgeable Cai Yaobin couldn’t help but tremble at this moment.
“No.” Kang Chi smiled, “It’s just that the sodium battery released before has left some room.”
“…”
Cai Yaobin suddenly realized.
However, if we infer from this, it means that Kang Chi’s sodium battery technology can achieve 500wh/kg?
It’s terrifying! Cai Yaobin couldn’t help but look at Kang Chi again. The young man in front of him, who was a generation younger than him, seemed ordinary, but he made him feel like a mountain with no end in sight.
”What about the cost?”
”Because some rare earth materials are needed, it will be slightly higher, about 1,200 yuan per kilogram. Can you accept me selling it at double the price?”
”I can accept it!” Cai Yaobin nodded quickly, “We want as many as you make!”
In fact, after guessing that this surprise was a lithium battery, Cai Yaobin had imagined its application prospects.
The first thing that came to mind was naturally the electromagnetic catapult of the aircraft carrier.
As we all know, the electromagnetic catapult of an aircraft carrier has very high power. For example, the power of a single catapult of the Ford is as high as 30 megawatts.
So many people think that if the aircraft carrier is equipped with a nuclear power device, the huge power demand of the electromagnetic catapult device on the aircraft carrier can be solved.
However, this is not the case. Although the electromagnetic catapult has high power, it is only 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 level that can meet the electromagnetic catapult. The fluctuation of the power grid will be very large.
So we can only use batteries to store energy, and when we need to launch, we can use supercapacitors to discharge ultra-high power instantly.
For example, on the 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, may be able to meet the power demand for launch.
Supercapacitors can charge a large amount of electric energy in a short time, and can also release a large amount of electric energy in an instant, but its electric energy naturally loses quickly, so it 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 guarantees logistics and the other guarantees output.
Therefore, power generation, or conventional power and nuclear power, have never been the key to limiting the performance of electromagnetic catapults, but energy storage.
If Kangchi’s 1200wh/kg energy density lithium battery is used as an energy storage station for supercapacitors, due to its high energy density, small size, and high safety, supercapacitors will no longer have to worry about insufficient electricity! This means that the number of aircraft that can be launched by aircraft carriers in a short time will be greatly increased, and at the same time, catapults with higher power can also be made.
The improvement of the combat effectiveness of aircraft carriers cannot even be described by data.
On a battlefield that changes rapidly, warplanes are fleeting, and the importance of being able to eject carrier-based aircraft in a shorter time can be imagined.
While Cai Yaobin was still immersed in the joy of the supercapacitor, Kang Chi lifted another piece of black cloth.
”This is the second surprise for you, super neodymium magnets!”
