Chapter 315 Powerful Battery

"Yes. Pen, Fun, Pavilion www.biquge.info" Zhao Chen thought about it, but decided to speak directly.

"Oh?" Liang Hong was immediately shocked.

"The next step for Mercedes-Benz is to prepare for the direct production of electric vehicles and start to seize the electric vehicle market, and we already have a higher performance battery in our hands, salt-ion lead-acid aluminum battery technology, and we have registered a patent for related technology, which is about three to five times the performance of the most advanced batteries now. Zhao Chen said it very simply.

In fact, this is nothing, just say it, but now these people here will not spread the news, Zhao Chen is not worried, they will not spread it.

The level of secrecy for everyone here is not low.

"Mr. Zhao, do you mean that according to the standards of Tesla cars in the United States, your battery range can reach more than three times it, that is, 1,500 kilometers, or even longer?" Professor Tu asked immediately.

"Yes, this is just the most basic numerical estimate, of course, we estimate that we will not launch such a high mileage car in the early stage, after all, the technology has to be updated, of course, if it is a high-performance production, the performance of the battery can be increased higher is not a problem, for example, ten times, or even twenty times is also possible, and the charging time will be greatly shortened. Zhao Chen said with a smile.

Professor Tu's eyes lit up directly, because the performance of the battery has increased, which means that it can be said that it is the energy pattern of the whole world that has changed, and there is no need to think about how many benefits there are.

Of course, the most important point is that the performance of China's submarines will be greatly increased. For example, the AIP submarine is a submarine that does not rely on air for propulsion.

The most common, and the most well-known is nuclear power. Because the nuclear-powered submarine is directly powered by a nuclear reactor, it can dive underwater for 90 or even 100 days, and even limit the nuclear submarine's lurking under water is not fuel and oxygen, but food supplies and the psychological endurance of the crew.

The AIP submarine generally refers to diesel-electric power submarines, that is, conventionally powered submarines. And submarines everyone knows that submarines need electricity, conventional power, diesel engines charge generators, but diesel engines need air. Therefore, the submarine that does not come to air propulsion does not mean that the diesel engine does not need air, but that there are other ways to supply oxygen to the diesel engine.

However, it is clear that the oxygen that can be carried in the submarine is limited, because the crew also needs to breathe, so the incubation time is naturally limited, although the underwater noise of the AIP submarine is generally lower than that of the nuclear submarine.

Because when using battery propulsion, the noise is lower than that of the main cooling pump of the pressurized water reactor and the steam turbine shock absorber, another major source of noise for nuclear submarines.

When the battery is propulsed, the noise is generally lower than these two, and the concealment of the submarine will naturally be greatly enhanced. Although the performance of China's AIP submarine is awesome, in fact, the ocean-going combat capability of this submarine is actually average, because the underwater self-sustaining power is not good, after all, no matter how awesome the battery is, you also have to charge.

Of course, this also has to do with the amount of power that can be stored in the current battery.

And most of the submarines are used for attack, but if Zhao Chen's battery can reach more than ten times that of the current mainstream battery, then it is another matter.

Because the battery of an ordinary conventional submarine is fully charged, the underwater cruising time is about 20 knots at a speed of 400 nautical miles, and a speed of 12 knots at a speed of 800 nautical miles.

If Zhao Chen's battery is used, according to the calculation of the maximum 20 times, this 20-knot speed can reach 8,000 nautical miles! 12-knots speed can reach 16,000 nautical miles! This already has a very terrifying combat performance!

But don't forget! The sailing time of a full charge of conventional submarines mentioned above only refers to the sailing time when the battery is fully charged, but in fact, these conventional submarines also need to carry a large amount of diesel fuel to start the diesel engine, and then charge the battery to ensure a longer cruising range.

And the volume of the battery is less than one-tenth of the volume of the diesel engine plus the diesel engine, so what if all the batteries are used instead of the diesel engine? Then this figure will have to be increased by at least 10 to 15 times, that is, if the speed is maintained at 20 knots, the submarine can sail 120,000 nautical miles! And the mileage at 12 knots will reach a terrifying 240,000 nautical miles!

According to the calculation of 12 knots, the distance around the Earth's equator is only more than 40,000 kilometers. And 240,000 nautical miles is equivalent to more than 440,000 kilometers, which can run ten laps around the equator. This already has a rather terrifying strategic value.

Of course, this is only a theoretical value, and this value must be achieved by a large submarine of more than 2,000 tons. Of course, if the submarine is larger, then theoretically the endurance will also increase.

Professor Tu is interested in this, "I don't know how much this battery costs? How much is a ton?" Professor Tu asked directly.

Zhao Chen choked for a moment, how big is the volume of a ton of batteries? And what kind of things can be used to calculate the weight in tons? The only thing Zhao Chen can think of is a few things, airplanes, ships, submarines, and rockets or space stations!

Although Professor Tu Zhao Chen in front of him didn't know what kind of expert he was, considering that the purpose of their first coming was to come for something similar to a tank, it is estimated that it is not enough to hang up with an airplane or the like, but it is very likely that a ship is possible, of course, an electric tank is not impossible.

Zhao Chen thought about it carefully in his head, and finally Zhao Chen thought about it, and made a decisive and direct analogy, "Let me make an analogy, if we build a large submarine of about 5,000 tons to 8,000 tons according to our latest battery, the cost of the battery alone is about 200 million US dollars." ”

Zhao Chen's words made Professor Tu and General Liang's eyes light up, 200 million US dollars, this cost cannot be said to be low, it can be said to be very high, and the price of a large nuclear submarine is about 2 billion US dollars, of course, this is the cost of Lao Mei, the domestic is not so high, but the domestic also needs about 1 billion US dollars.

If Zhao Chen's battery performance is really so terrifying, even if the cost is a little higher, the military is not unacceptable, the current Chinese military is not like the end of the twentieth century when everything has to give way to the economy, the current military can also be said to be rich.

And such a pure electric submarine, you know, although it is not like a nuclear submarine, theoretically unlimited endurance, but in fact it is no different from a nuclear submarine. Because of the nuclear submarine, you will be on a mission for more than 100 days at most, because the crew can't bear it, and the psychological pressure will collapse.

Therefore, the nuclear submarine also needs to rest after a few months of mission, if it is calculated in this way, Zhao Chen's battery can reach the same endurance, and when he returns to the port to rest, he will be charged directly in the port.

In that case, it will be no different from a nuclear submarine.

"Mr. Zhao, when will your batteries be produced? Liang Hong took over the conversation directly and asked quickly.

"Well, it's probably going to be the end of the year. Zhao Chen thought for a while.

"At the end of the year, if it is produced, can we test it?" said Liang Hongfei quickly.

"No problem, of course, if you're asking for a high-performance battery, say it up front, it's not in line with our production plan. Zhao Chen nodded.

The high-performance battery is not a salt-ion lead-acid aluminum battery, but a real graphene battery. These two are not the same concept at all, of course, graphene batteries are absolutely impossible to disclose, although this thing is already a public concept, the whole world knows that the performance of this thing is superior, but the foundation of large-scale industrialization has not yet been reached.

Everyone doesn't know how to industrialize this large-scale, so there is still a long way to go from large-scale use, and Zhao Chen now has a complete graphene battery and graphene material use technology in his hands, which Su Jie sorted out.

And after the integration of Elysium, Zhao Chen will definitely have more technology in his hands.

"No problem, if we can meet the conditions you said, Mr. Zhao, we dare to guarantee that we will definitely place an order, if possible, Mr. Zhao, can you provide a part, or we can design it first?"

Although China began to produce aircraft carriers, the second aircraft carrier was the same as the first Liaoning, and the conventionally powered aircraft carrier was chosen, more to test the shipbuilding industry and provide experience for the subsequent construction of nuclear-powered aircraft carriers.

And before the aircraft carrier is reached, the submarine is the weapon that threatens China the most, of course, even with the aircraft carrier formation, the submarine is absolutely indispensable.

If a pure electric submarine is really researched, and the battery is still so powerful, the nuclear submarine can really be decommissioned. There is no even need to study it, after all, nuclear submarines are not said to be absolutely superior.

The so-called unlimited range is also theoretical knowledge, because the power of the nuclear submarine is unlimited, could it be that your food is also unlimited? Is the psychological endurance of the members on the submarine also unlimited? So this is just a relative process.

If the battery lasts that long, then it's perfectly fine, no different from nuclear power. Of course, the charging device should also be more advanced.

"Of course you can, you can design it first, I don't know what kind of battery the submarine uses, but let me put it this way, if you design a pure electric submarine according to an 8,000-ton submarine, it is not a problem to charge it once, and at a speed of 30 knots, it is not a problem to circle the earth several times. Zhao Chen said very simply.

The big deal can be reached by directly upgrading the graphene battery to a certain point.

"Okay, then let's go back and start gathering experts to design an electric submarine, of course, as a pure verification model, it may not be that large at the beginning. Liang Hong thought for a while. (To be continued.) )
