The Science Fiction World of Xueba

Calculated according to the average power density of Jinlong batteries of 2.5kwh/kg, if there is a conventional submarine with a displacement of 3,000 to 5,000 tons, all power systems such as battery packs, diesel units, generator sets, and oil storage tanks inside will be replaced by Jinlong Batteries, at least 600 to 800 tons of Jinlong batteries can be carried.

In this way, only relying on the power stored in the Golden Dragon battery, a conventionally powered submarine can be submerged at full power for more than half a month at a speed of more than 30 knots, and can sail around the world at a cruising speed of 10 to 12 knots.

If such a submarine is equipped with the same level of communication system, command and control system, weapon system, electromechanical system, sonar system, etc. as the nuclear submarine, its combat effectiveness will instantly be comparable to that of the nuclear submarine.

Moreover, the complex mechanical transmission devices in the nuclear submarine, such as gearboxes, steam turbines, drive shafts, etc., have been removed, and the noise level of the Jinlong battery submarine can be greatly reduced to below 90 decibels, which can be called a true oceanic black hole.

As for the price of this kind of submarine, even if the Jinlong battery is calculated at 10,000 RMB/kg, the price of a Jinlong battery submarine can be controlled within 10 billion RMB.

Compare the prices of the latest models of submarines in the world.

The next-generation Columbia-class strategic nuclear submarine of the United States is estimated at 12 billion US dollars according to the price in 2013, which is equivalent to 80 billion RMB.

The British successor-class strategic nuclear submarine has a unit price of 12 billion pounds, equivalent to 120 billion RMB.

Even Russia's Borei-class nuclear submarine costs as much as 60 billion RMB.

In contrast, although the price of domestic nuclear submarines is much lower, it has generally reached the level of 30 billion RMB.

If you compare conventional power submarines, the latest generation 218SG purchased by Singapore from Germany is equipped with a new generation of conventional power submarines with a fuel cell system, with a displacement of 2,000 tons, and the fuel cell system ensures continuous underwater navigation at a speed of two to six knots. For more than a week, Germany's ThyssenKrupp Marine Systems offered up to 900 million US dollars.

The emergence of Jinlong batteries will greatly enhance the combat effectiveness of the Chinese Navy's submarine fleet, which can even match or even surpass that of the US Navy's submarine fleet.

And this is just the application of Jinlong batteries in submarines.

In the field of surface ships, King Long Battery will also completely solve the problem of the power source of surface ships, and even make the legendary electromagnetic guns, laser cannons and other weapons officially enter the stage of future naval warfare.

Not to mention the aviation field,

At least in weak areas such as heavy transport aircraft, aerial refueling aircraft, early warning aircraft, anti-submarine patrol aircraft, and electronic warfare aircraft, with the power and endurance level provided by Jinlong batteries, China can definitely create an all-electric aircraft comparable to Boeing jetliners.

Even put it into the field of civil aviation, in terms of range and flight cost, I want to have a lot of advantages over jet airliners.

As for the aerospace field, this is such an artifact.

Whether it is high-throughput communication satellites, space-based telescopes, deep space probes, next-generation space stations or even manned moon landing spacecraft, high-energy-density power supplies will greatly improve the performance of these devices.

Therefore, the military’s concern is that if such a piece of killer equipment is not subject to export control, it is likely to lead to a deterioration of the regional security situation, which in turn will affect China’s national defense interests.

The opposing side believes that the greater role of Jinlong batteries should be in the field of people's livelihood.

Needless to say, all-electric vehicles, civil aviation aircraft, computers, mobile phones, energy storage power stations... all fields can flex their muscles.

Especially in the context of the current Sino-US trade war, the emergence of Jinlong batteries will provide a powerful source of power for China's industrial upgrading.

Moreover, China can use Golden Dragon batteries to join forces internationally, disintegrate the strategic alliance of the United States, and even exchange technologies related to Golden Dragon batteries to lift the high-tech blockade of Western countries on China.

The views of both sides are deadlocked.

Finally, after a week of intense discussions, Pang Xuelin technically proposed a solution.

In civilian fields, such as mobile phones, computers, automobiles and other fields, the specifications and standards of Jinlong batteries are controlled at one kilogram per battery, and the energy storage density is about 1.5kwh/kg.

In this case, even if these batteries are connected in series on a large scale, due to power management problems, there is no way to carry out large-scale applications in the military field.

As for the military version, King Long will manufacture batteries with different specifications and standards according to the different requirements of different fields such as aerospace, aviation, and ships.

These batteries, the country will formulate strict export control policies.

...

A month passed in a flash. During this month, Pang Xuelin stayed in the capital, basically going around every day, holding meetings with various departments.

Ministry of Industry and Information Technology, Ministry of Science and Technology, Chinese Academy of Sciences, Academy of Military Sciences, Ministry of Equipment Development, FGW, SASAC, etc.

He didn't even have time to meet Yao Bingxia.

However, as the bet between him and Tian Hong approached, online discussions about lithium-air batteries gradually increased.

Since the lithium-air battery project team has entered a state of high secrecy after the military intervened.

The laboratory where the project team is located has been closed on a large scale in the name of renovation, which has led to no news about lithium-air batteries on the Internet.

Many people ridiculed him on the Internet. Professor Pang was so ashamed this time. Even the "New York Times" published an article mocking Pang Xuelin, thinking that he was playing the emperor's new clothes trick. You have to bet with others out of face.

On the contrary, the Stanford doctor named Tian Hong publicly stated in Zhihu's column that even if he won the bet, he did not want Professor Pang to fulfill his bet and quit the academic circle. After all, in the professional field, Pang Xuelin has the world top level.

Amid the turmoil on the Internet, the time has entered June unknowingly.

...

Tuesday, June 8, 2021.

At nine o'clock in the morning, Andrew Barton, the China correspondent of The New York Times, had just entered the office when he was called to the office by his boss.

"Barton, this is the invitation letter we just received. The China GWY Press Office will hold a press conference at 3:00 pm. You should prepare and go there then."

"Press conference for China GWY?"

Patton was slightly taken aback, and asked in confusion, "No major events have happened during this period, right? Why are the Chinese suddenly going to hold a press conference?"

The boss shook his head and said: "I don't know, but not only we have received the invitation letter, but all the foreign media stationed in Beijing should have received the invitation letter, and in the news program not long ago, CCTV also officially announced to the outside world, The Chinese government will hold a very important press conference at 3:00 p.m., and I hope people across the country will pay attention to it. Now that social media in China is going viral, many people are speculating about what China is going to announce to the outside world Such big news."
