Chapter 324 Effects of Lithium-Air Batteries
Chapter 325 Impact of lithium-air batteries

At the same time, the Chinese military has also begun to change its military layout for lithium-air batteries. After all, such a lithium-air battery is not only used in the civilian field, but also has a very wide range of applications in the military field.

For example, in the field of conventional powered submarines, it is simply a subversive strategic equipment.Although it is said that AIP submarines have proliferated on a large scale in the world at present, and many medium-sized countries have already equipped AIP submarines, compared with nuclear-powered submarines, due to the energy storage limit of batteries, AIP submarines are not as good in terms of overall diving depth, power, sonar and There is a considerable gap between the power of various electronic equipment and nuclear submarines.

The fighting power between the two is naturally not the same.

This is also an important reason why the US Navy abandoned conventional powered submarines and chose to maintain an underwater all-nuclear submarine.

However, the emergence of lithium-air batteries has broken the combat barrier between conventional power submarines and nuclear submarines.

Calculated according to the specific energy of the lithium-air battery with a large volume of 3.5Kwh/kg, if a conventional submarine with a displacement of [-] to [-] tons, all the power systems such as battery packs, diesel units, generator sets, and oil storage tanks inside will be Replaced with lithium-air batteries, at least [-] to [-] tons of lithium-air batteries can be carried.

In this way, only relying on the power stored in the lithium-air battery, a conventionally powered submarine can sneak at full power at a speed of more than 20 knots for more than 10 days, and at a cruising speed of 15 to [-] knots, it can completely sail around the world. .

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

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

Therefore, in order to prevent military use by other countries, at least in the short term, the military requires China Great Wall and Narcissus Era to only produce standard lithium-air batteries and below, and not to produce large lithium-air batteries.

Without a complete set of technologies, foreign countries want to break through technical difficulties, so it is not a matter of one or two years, especially after Qin Yuanqing received a request from the military, he specially manufactured a battery self-destruct device. Once someone uses external force to study lithium-air batteries, Then the self-destruct device will be activated. Of course, the self-destruct device will not make the lithium-air battery explode, but the thin film separating oxygen will dissolve, and the lithium-air battery will fail instantly.

Although I don't know how long it can delay the breakthrough of lithium-air battery technology in developed countries, it is no problem to think that it can be delayed for a few years.

The military has begun to transform several submarines under construction to use lithium-air batteries, and other conventionally powered submarines that are being overhauled have also been transformed to use lithium-air batteries as energy sources.

After all, the use of lithium-air batteries as the energy source of submarines can actually greatly reduce costs. Calculated at 33 per ton, the cost of lithium-air batteries for 2 to 2.64 tons is 100 million to [-] million, making a ship equipped with lithium-air batteries The price of the submarine is less than [-] billion yuan without load.

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 to be 2013 billion US dollars according to the price in 120, which is equivalent to more than 700 billion yuan.

The British successor-class strategic nuclear submarine has a unit price of 120 billion pounds, which is almost equivalent to hundreds of billions of dollars.

Even Russia's Borei-class nuclear submarine costs as much as 600 billion yuan.

In contrast, although the price of domestic nuclear submarines is much lower, it has generally reached the level of 300 billion yuan.

If you compare conventional power submarines, Deutsche’s 218SG is equipped with a new generation of fuel cell system conventional power submarines, with a displacement of 2000 tons. The fuel cell system ensures that it can sail continuously underwater for more than three weeks at a speed of 9 to 50 knots. ThyssenKrupp Maritime Systems' quotation was as high as [-] million US dollars, which also exceeded [-] billion yuan.

The application of lithium-air batteries in submarines will greatly reduce the cost of submarines and greatly enhance the combat effectiveness of the Huaxia Navy's submarine fleet.

Of course, in the military field, not only on nuclear submarines, but also on water ships, many batteries that originally used batteries can now use lithium-air batteries.In terms of drones, the use of lithium-air batteries has the ability to cruise around the world and has a strong strike capability. After all, drones are limited. One of the most important reasons is that the battery capacity is not enough, which limits the range.

The military is also a big spender, and has begun to transform the formerly decommissioned aircraft into drones, using lithium-air batteries to enhance the strength of the army.

On the islands and reefs of the South China Sea, on the Qinghai-Tibet Plateau, and the barracks on the Yunnan-Guizhou Plateau, places that were originally limited by electricity have also begun to be relieved by lithium-air batteries, and even cold places can be heated.

Wait until the lithium-air battery is exhausted, and then transport it back to the rear to charge.

Armored vehicles, tanks, artillery vehicles, personnel carriers, etc., which originally used cars and diesel, have also begun to turn to lithium-air batteries one by one.

Of course, the reform in the field of military and military industry does not happen overnight. It takes two or three years to complete these reforms.

These have to be done step by step.

Qin Yuanqing has no time to manage the military industry reform of the army. At this time, he is participating in a high-level meeting. The National Development and Reform Commission, Huaxia Nuclear Industry Group and various ministries and commissions are participating in the meeting. The theme of the meeting is about increasing power generation.

After all, Huaxia's power consumption will increase sharply in the future, and the existing power generation capacity is estimated to be unable to meet the requirements in two or three years.

Therefore, it is imperative to increase power generation. With the implementation of the goal of carbon neutrality, energy conservation and emission reduction have become a general trend. Thermal power will not increase but will further decrease.

Under such circumstances, there is no choice but to increase hydropower, wind power, solar energy, tidal power and nuclear power plants, among which nuclear power plants are the top priority.

For hydropower stations, the country is already advocating the phase-out of small hydropower stations with poor efficiency and backward production capacity. There will be tens of thousands of small hydropower stations eliminated. Basically, large-scale hydropower stations can be built. With abundant resources and a large river drop, at least 3 to 5 large hydropower stations equivalent to the Three Gorges Project can be built, but it is more complicated and difficult to handle.

So the focus is on wind power, solar power, tidal power and nuclear power plants.

"Dear comrades, according to the relevant data, my country's power generation capacity will exceed 6 trillion kwh this year. Our goal is to achieve 2021 trillion kwh by 8 and 2025 trillion kwh by 10 The power generation has reached [-] trillion kwh." The leader said in a deep voice.

"Leader, should we increase the construction of nuclear power plants? Otherwise, this goal will be too difficult and difficult to achieve!" A director made a suggestion.

"Then speed up the construction of nuclear power plants. Hasn't your department been studying the possibility of building a large-scale hydropower station on the Yarlung Zangbo River? After studying for so long, you should have a conclusion. Build it if you can. Some external factors should be eliminated or should be eliminated. Yes, when building water conservancy facilities at home, why do you always have to look at other people's faces?" The leader said angrily.

Several other leaders looked at each other, already knowing it in their hearts.

Upon seeing this, Qin Yuanqing raised his hand to indicate that he had an opinion, and the leader smiled and said, "Academician Qin, do you have any suggestions to add?"

Qin Yuanqing said into the microphone: "Leaders, my suggestion is about nuclear power plants. I suggest that when building a new nuclear power plant, we must consider the application of controllable nuclear fusion in the future, and reserve room for future nuclear power plants to be transformed into controllable fusion."

The leader immediately became interested: "Academician Qin, as far as I know, there is still a long way to go before commercial application of controllable nuclear fusion."

"Leader, you are right. Now my country's controllable nuclear fusion has just achieved a breakthrough of burning at 1 million degrees for 30 seconds. At present, the world's most advanced French superconducting tokamak has a plasma temperature of 120 seconds when the discharge time is 2000 seconds. [-] million tons. The progress of all major countries in the field of controllable nuclear fusion is similar, and there is still a long way to go before controllable nuclear fusion." The leader of Huaxia Nuclear Industry Group said.

Qin Yuanqing said calmly: "In fact, from the theoretical point of view, controllable nuclear fusion is no longer difficult. Now it is the materials and technicians who limit controllable nuclear fusion. At most, by 2030, controllable nuclear fusion will definitely be realized. .”

"So from the perspective of saving construction costs and avoiding repeated construction, I suggest that when designing and constructing nuclear power plants at this time, there is room for future changes to nuclear fusion. Even if the investment increases due to this, it is acceptable." Qin Yuanqing said.

"Academician Qin, is there any basis for what you said?" the leader of Huaxia Nuclear Industry Group asked.

"My words are the basis!" Qin Yuanqing said confidently.

When the others heard Qin Yuanqing's words, they looked at each other in blank dismay. Shouldn't science show data to seek truth from facts and be reasonable? Why is it like a slap on the head now?

The leader was thoughtful, and then a flash of determination flashed in his eyes, and said: "Academician Qin's suggestion is very necessary. Temporarily increasing investment will help save future construction costs."

Leader, this is unscientific!

Everyone else wanted to complain, but the leader had already spoken, and it was always bad to refute now, so I had to think about responding to the leader after the meeting was over.

Only after the meeting was over, the leader and Qin Yuanqing were together, discussing controllable nuclear fusion with great interest.

In fact, for leaders, since Qin Yuanqing is the greatest authority, and has always performed outstandingly and achieved miraculous achievements time and time again, isn't it the most normal and reasonable to choose to believe Qin Yuanqing's words?

Needless to say, this lithium-air battery alone will play an inestimable role in China's development.
