According to the calculation of the average power density of 2.5kwh/kg of the Golden Dragon battery, if there is a conventional submarine with a displacement of 3,000 to 5,000 tons, the battery pack, diesel unit, generator set, oil storage tank and other power systems are all replaced with the Golden Dragon battery, at least 600 to 800 tons of the Golden Dragon battery can be carried.

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

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

Moreover, by removing the complex mechanical transmission devices in the nuclear submarine, such as gearboxes, steam turbines, transmission shafts, etc., the noise level of the King Long battery submarine can be greatly reduced to below 90 decibels, which can be called a black hole in the ocean in the true sense.

And the price of this kind of submarine, even if the Golden Dragon battery is calculated according to 10,000 RMB/kg, the price of a Golden Dragon battery submarine can be controlled within 10 billion RMB.

Compare the prices of the latest models of submarines internationally.

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

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

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

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

If you compare the conventionally powered submarines, the latest generation of 218SG purchased by Singapore from Germany is equipped with a new generation of fuel cell system for conventional power submarines, with a displacement of 2,000 tons, and the fuel cell system ensures that it can sail underwater continuously for more than three weeks at a speed of two to six knots, and the price quoted by the German company ThyssenKrupp Marine Systems is as high as 900 million US dollars.

The emergence of the Golden Dragon battery will certainly greatly enhance the combat effectiveness of the Chinese Navy's submarine fleet, and can even match or even surpass the submarine fleet of the US Navy.

And this is just the application of the Golden Dragon battery on submarines.

In the field of surface ships, the Golden Dragon battery will also completely solve the problem of the power source of surface ships, and even make the legendary electromagnetic cannons, laser cannons and other weapons officially appear on the future naval battle stage.

Not to mention the aviation field, at least in the weak areas such as heavy transport aircraft, air tankers, early warning aircraft, anti-submarine patrol aircraft, electronic warfare aircraft, etc., with the power and endurance level provided by the Golden Dragon battery, China can completely create an all-electric aircraft comparable to the Boeing jet airliner.

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 in the aerospace field, this is such an artifact.

Whether it's high-throughput communication satellites, space-based telescopes, deep space probes, next-generation space stations, or even manned spacecraft to the moon, power supplies with high energy storage density will greatly improve the performance of these equipment.

Therefore, the military's concern is that such a killer piece of equipment is likely to deteriorate the regional security situation without export controls, which in turn will affect China's defense interests.

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

Needless to say, all-electric power vehicles, civil aircraft, computers, mobile phones, energy storage power stations, ...... You can make a big difference in all fields.

Especially in the current environment of the Sino-US trade war, the emergence of King Long battery will provide a strong source of power for China's industrial upgrading.

Moreover, China can use the Golden Dragon battery to cooperate in the international community, dismantle the strategic alliance of the United States, and even use the Golden Dragon battery-related technology as an exchange to lift the high-tech blockade of China by Western countries.

The two sides are deadlocked.

Eventually, after a week of intense discussions, Pang Xuelin came up with a technical solution.

In the civil field, such as mobile phones, computers, automobiles and other fields, the specifications and standards of King Long batteries are controlled at one kilogram per unit, 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, there is no way to carry out large-scale application in the military field due to power management problems.

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

For these batteries, the state will formulate strict export control policies.

……

A month passed in a flash, and during this month, Pang Xuelin has been staying in the capital, basically rotating every day, contacting and 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, State-owned Assets Supervision and Administration Commission, etc.

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

However, as the bet between him and Tian Hong approached, the discussion about lithium-air batteries on the Internet 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 coming out on the Internet.

Many people ridiculed on the Internet that Professor Pang was embarrassed this time, and even the "New York Times" published an article ridiculing Pang Xuelin, thinking that he was playing the trick of the emperor's new clothes, obviously being deceived, and making bets with others for the sake of face.

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

In the midst of the disturbances on the Internet, time has unconsciously entered June.

……

Tuesday, June 8, 2021.

At nine o'clock in the morning, Andrew Patton, a New York Times correspondent in China, had just entered the office when he was called into the office by his boss.

"Barton, this is the invitation we just received, the China GOUR press office will hold a press conference at 3 p.m., you can get ready, go there then."

"Press conference for China's GW?"

Barton was slightly stunned, and wondered: "Nothing major has happened during this time, 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, all the foreign media currently in Beijing should have received the invitation letter, and not long ago in the news program, CCTV also officially announced to the outside world that the Chinese government will hold a very important press conference at three o'clock in the afternoon, and I hope the people of the whole country will pay attention to it." Now that China's domestic social media is about to explode, many people are speculating about what kind of major news China is going to announce to the outside world. ”
