Chapter 437 Energy Revolution
The "relevant technology" that Xu You referred to was the high-energy-density lithium battery technology that Xu You contributed when he first studied the battery for the Fulon mobile phone.
Just by replacing the positive electrode material of the battery, Xu You increased the energy density of the mobile phone lithium battery by about 40%.
If this technology can be adjusted, it may be used in power storage systems.
After hearing Xu You's words, everyone became more confident about this topic.
"Since Professor Xu has already done relevant research, we have nothing to worry about. Once the superconducting cables are laid, coupled with an efficient energy storage system, we will truly be at the top of the world in the energy field!"
These achievements are worthy of being called a disruptive "energy revolution."
And these are just the research done in the field of electric energy transportation and storage.
In addition, Xu You also has a "Dongri" controlled nuclear fusion project under his control.
If this project is successful, it can be said that the energy problem has been completely solved from the source.
After coming out of the conference hall, Xu You recalled some things in the past and suddenly solved a puzzle of his own.
"No wonder my mother always asked me to call her Teacher Wu. It turns out that this is the internal custom."
When everyone is of different ages and qualifications, calling each other "teacher" is indeed a good way.
With the identity of "scientific research decision maker", Xu You can also start new projects more conveniently, and basically no longer need to apply for anything.
If Xu You needs people to help him with the project, he can use his power to dispatch these people to his project team.
"Let's do the research inside Jijing University first."
With the current academic strength of Jijing University, most of the problems can basically be solved.
If other experts are really needed, it won’t be too late for Xu You to call them later.
For this project, Xu You still brought Lin Shi with him.
"Lin Shi, this project is to study a highly efficient energy storage lithium battery. You may not have been exposed to this topic before, so focus on learning it this time."
Xu You did this not only because Lin Shi was his student, but also because Lin Shi really had strong comprehensive strength and was worthy of his investment of resources to cultivate.
After all, you can't do everything by yourself, you need more outstanding talents to step up.
"Teacher, I know that the country has been vigorously promoting the research of energy storage lithium batteries recently, with the goal of developing energy storage lithium batteries with high energy storage efficiency, ultra-long life, and high safety. In fact, I have done some research on the battery of Fulong mobile phones before. If I am not mistaken, the positive electrode material of this lithium battery should be the same as that used in the battery of Fulong mobile phones, right?"
"Huh? You know all this?"
Xu You didn't expect that Lin Shi had the energy to conduct research in other areas besides studying and working.
"Of course, this is the result of your contribution, and Fulong Technology is Luo Wenkun's company, so it's not surprising that I know this. Teacher, you have always taught me not to limit my vision to a small field, but to broaden my research field. So in my spare time, I often study knowledge in other fields."
"Well, this is a good habit. As long as you have enough energy, it will always be beneficial to be exposed to more other knowledge."
In a normal scientific research system, as the research level improves, the research fields become more and more specialized.
For example, if you majored in physics in undergraduate studies, your research direction would be narrowed down to condensed matter physics in your master's degree.
When I got my doctorate, I only studied the field of superconductivity in condensed matter physics.
This is very normal and completely correct for most researchers.
But if you want to reach a higher level, you must expand your knowledge and be able to think about problems from a higher perspective.
Otherwise, you can only become an expert in a certain field but cannot become a strategic scientist.
Like Lou Song, Xu You once hoped that he could focus on research purely and not let other things affect his research.
But when Xu You gradually came into contact with some internal affairs.
Only then did I realize that if we cannot truly stand at the top of the world, it will be difficult for our researchers to have the best scientific research environment.
Xu You must shoulder more responsibilities in order to allow a talented person like Lou Song to unleash all his energy.
After the project team was formally established, Xu You organized everyone to discuss the future development of the project.
"This time, our goal is to develop energy storage lithium-ion batteries with ultra-long life, high safety and high power storage capacity. In terms of battery grouping, we now have two options: SCM structure and PCM structure."
The SCM structure and PCM structure refer to series connection first and then parallel connection, and parallel connection first and then series connection, respectively.
The types of batteries are also divided into groups of small-capacity single cells and single large batteries with larger capacity.
After Xu You finished his main speech, a battery expert from Jijing University raised his hand and said:
"Professor Xu, I suggest that we use small-capacity single-cell battery groups. Many practical applications have proven that small-capacity single-cell battery groups have more obvious advantages than large-capacity batteries in terms of safety, reliability, and manageability."
The expert cited some examples and explained the specific reasons through theory.
"Yes, this is the main direction I suggest. But when nothing is certain, we still cannot give up other possibilities."
When Xu You was looking up information before, he also knew that the method of grouping small-capacity single-cell batteries was the best option at present.
The energy storage system of a certain Tesla electric vehicle is composed of nearly 10,000 small-capacity single batteries through a PCM structure.
But this does not mean that this is the ultimate answer to the lithium battery energy storage system. The project team still needs to work hard to find a better energy storage solution.
For example, although the discharge capacity of Tesla's PCM structure battery pack is greater than that of the SCM structure, it does not take into account the impact of different combinations of single cells in the battery pack on the performance of the battery pack.
This means that the life of the entire battery pack is not very ideal, and the entire battery pack needs to be replaced every few years.
Of course, these problems are not limited to a certain brand, but are widespread problems in the entire field.
These problems must never occur in the power system.
