Li Yuzhang, as the grandson of Academician Li Chunhua, has been immersed in his own research since he entered the master company. Unlike his grandfather, Li Yuzhang's main research direction is energy storage batteries. It's just that there has been no achievement on this. But this is understandable. There are so many scientists in the world. If every one of them could make some achievements, the earth would take off long ago. In fact, there are not even one tenth, or even one percent, of scientists who can truly make achievements! Most people are replicating other people's research.
However, his grandfather sent him to a master company despite his objections, which made him very dissatisfied. To be honest, I am skeptical about the start-up companies of these young people who have not even obtained a diploma. I am even a little suspicious of these people.
In addition, after joining the master company, although I received certain care, after all, I could no longer go all out to research my own battery technology.
However, things took a turn for the worse. At the end of summer last year, Gaoshou Company was actually able to undertake research tasks for the Chinese national department, and allowed me to follow them, allowing me to have a thorough understanding of this new Gaoshou Company. From then on, my attitude began to change.
At this time, Li Yuzhang also began to discover that the research technology within the master company seemed to be completely different from the mainstream research technology in the world! Here, there are no extensive English foreign language materials. You must know that many technologies in the world were developed in countries such as Germany, the United States, and Russia. If China wants to learn first, it has to learn English, so that many experts are proficient in English. So a lot of energy was spent.
But the technology of Gaoshou Company has many differences besides words, but it is not very clear. In addition, there is a method of fitness practice that is commonly promoted within expert companies, but this requires a strict confidentiality agreement. He even swore to God that if he left the master company, he would be taken back! No matter how you look at it, it looks a bit like a novel!
However, after practicing, I am full of energy, my mind is sharp, and my body is getting stronger. I have never suffered from any illness, and I even surpassed the world champion in the 100-meter dash recently when I ran! All of a sudden, I completely changed my mind!
Now, I heard that Gaoshou Company was planning to establish an energy storage system, so I submitted an application report. No doubt, as one of the few people working on battery research within the company, Li Yuzhang got permission.
Looking at Liu Donghai and Qi Fengwu sitting above, Li Yuzhang was filled with envy. It was said that the senior executives of these companies practiced more advanced techniques than himself. Unexpectedly, Qi Fengwu looked like a fairy, and the top executives of the expert company The female leaders are all as beautiful as gods, with unique and luxurious temperaments. It is said that these are the benefits brought by spiritual practice.
However, the strict confidentiality agreement has kept Gao Shou Company silent. The outside world still does not know that spiritual practice is being popularized within Gao Shou Company.
Today is the energy storage system meeting within Gaoshou Company. A few days ago, Gaoshou Company started a research plan to address aircraft technical difficulties, and Liu Donghai and Qi Fengwu were assigned to research on energy storage. Now, after several days of convening, there are 20 researchers here, including 5 researchers who have been to the China Aerospace Research Center.
Liu Donghai spoke slowly. Now the former college student has become more and more aura like a company executive: "Everyone, good afternoon. Today, on the one hand, we will get to know each other, and on the other hand, we will also discuss and determine the future research and development of energy storage systems. Direction.
Based on the information submitted by everyone, I have made a summary and will also make a report here. If you have any questions, you are welcome to discuss them.
First of all, there are many ways to store energy in the world, but there are very few technologies that can meet the needs of aerospace, or even very few.
Nowadays, the world has gone through long-term verification and discussion, and it has basically been decided that the future power technology will be mainly electric energy, and plasma engines will be the main direction of attack in the future. If the first technological revolution was the steam engine, the second was the internal combustion engine, and the third was the electric motor, then the new technological revolution is the plasma engine.
Whoever masters the mature technology of plasma engines and supporting energy supply systems will master the heart of future space control! This is already recognized by everyone.
But while the plasma engine is improving super kinetic energy, we have to face one problem, and that is energy consumption! Take the Flying Dragon fighter jet we participated in last time as an example. A half-hour flight with two engines actually consumes as much electricity as a city with a population of one million for one hour!
Maybe this was unimaginable before, but now it is indeed a problem we must face.
If the engine is the heart, then energy is food. Without sufficient food, the aircraft will not last long. Therefore, what is before us is how to study huge energy storage systems.
According to the technologies provided by everyone, the following technologies can be used in aerospace: fuel cells, nuclear fission reactor technology, and super batteries. Among them, super battery technology is divided into cultural energy storage and physical energy storage.
However, among various technologies, fuel cells require a large amount of fuel and oxygen, which increases the burden on the system, and the energy output per unit time is too small. It is estimated that under the premise of limiting the volume, it can only meet the consumption of ordinary civilian propeller aircraft. Basically ruled out.
As for the second nuclear technology, everyone knows that even small nuclear reactors can be placed in cars. However, for such a size, the output power of the current nuclear technology is too low, and the dynamic stability and safety of the nuclear reactor are not good. To achieve large amounts of energy output, a nuclear reactor needs to be big, big! Subsonic aircraft can use nuclear reactor technology, but for supersonic aircraft, their power output cannot keep up. This point has been studied for half a century at home and abroad, and the final conclusion is to give up.
Therefore, there are only two roads before us today: chemical super storage batteries and physical super storage batteries.
Among them, the pinnacle of chemical batteries should be the current sodium-lithium-ion battery technology. Each kilogram of weight can store 100 kilowatt-hours of electrical energy. According to aviation design, if the battery weighs one ton, it can store 100,000 kilowatt-hours of electrical energy, which is enough for ordinary aircraft. , the fighter still has some shortcomings. Even if 10 such batteries are installed on current aircraft, the cost will be extremely high. Moreover, ten tons is too heavy. However, having such technology and data also shows that chemical energy storage batteries still have a bright future.
In addition, the second type is physical energy storage. Different from chemical energy storage, which relies on chemical bonds, physical energy storage relies on electronic transitions. Nowadays, China's relatively mature technology is: magnetic field-sealed electron leap-forward energy storage battery, which uses a strong magnetic field to bind high-energy electrons around the nucleus to complete energy storage. When releasing energy, electrons jump from a high orbit to a low orbit, thereby releasing a huge amount of energy.
Now, one such battery in China weighs about 2.8 tons and can store 600,000 kWh of energy. But the working area inside is only about 0.8 tons, and the rest are all various security devices. Therefore, two research projects are officially launched today, chemical batteries and physical batteries. Everyone can apply for research projects individually. Sufficient funds and experimental equipment are available. ”
