The "related technology" that Xu You refers to is the high-energy-density lithium battery technology contributed by Xu You when he first researched the battery of Fulong mobile phone.

Just by replacing a positive electrode material of the battery, Xu You increased the energy density of the lithium battery of the mobile phone by about 40%.

If some adjustments can be made to this technology, it is hopeful that it can be used in the energy storage system of electric power.

Hearing Xu You's words, everyone became more confident about this topic.

"Since Mr. Xu has done relevant research, we have nothing to worry about. When the superconducting cable is laid and the efficient energy storage system is added, we will truly stand on the top of the world in the energy field." Peak!"

These achievements are enough to be called a subversive "energy revolution".

And these are just the research done in the part of electric energy transportation and storage.

In addition, Xu You also has a "Dongri" controllable nuclear fusion project under his command.

If this project can be 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 past events, and suddenly solved a confusion of his own.

"No wonder my mother kept asking me to call her Teacher Wu. It turns out that this address is an internal addressing habit."

When everyone is different in age and qualifications, it is indeed a good way to address each other as "teachers".

And with the status of "scientific research decision maker", Xu You can also start new projects more conveniently, and basically does not need to apply for anything.

Xu You can also use his own power to dispatch these people to his project team as to who he needs to help him with the project.

"Let's do research inside Jijing University first."

With the current academic strength of Jijing University, it can basically solve most of the problems.

If other experts were really needed to be present, it would not be too late for Xu You to call in later.

In this project, Xu You still brought Lin Shi by his side.

"Lin Shi, this project is to study a high-efficiency energy storage lithium battery. You may not have had much contact with this topic before, so let's focus on learning this time."

Xu You did this not only because Lin Shi is his student, but also because Lin Shi really has a strong comprehensive strength and is worthy of investing resources in training.

After all, it is absolutely impossible to rely on yourself alone in everything, and more outstanding talents need to stand up.

"Teacher, I know that the country is vigorously promoting the research of energy storage lithium batteries recently. The goal is to develop energy storage lithium batteries with high energy storage efficiency, ultra-long life, and high safety. I have done some research on the battery, if I am not wrong, the positive electrode material of the lithium battery this time should be the same as that used in the cell phone battery of Fulong, right?"

"Huh? You know all about this?"

Xu You did not expect that Lin Shi would have the energy to conduct research in other fields after studying and working.

"Of course, this is the result of your contribution, teacher. Fulong Technology is Luo Wenkun's company. I know this is not surprising. The teacher has always taught me not to limit my eyes to a small field, but It is to broaden my research field. So in my spare time, I will 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 get in touch with other knowledge."

In the normal scientific research system, usually with the improvement of the research level, the research fields are divided into more and more finer details.

For example, if you major in physics for your undergraduate degree, your research direction will be narrowed down to condensed matter physics for your master's degree.

When it comes to Ph.D., he only studies the field of superconductivity in condensed matter physics.

For the vast majority of researchers, this is very normal and completely correct.

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, one can only become an expert in a certain field, but not a strategic scientist.

Xu You used to be the same as Lou Song, hoping that he could do research purely instead of letting other things affect his research.

But when Xu You gradually came into contact with some internal affairs.

I just realized that if we can't really stand on top of the world, it will be difficult for our researchers to have the best scientific research environment.

Xu You had to take on more responsibilities in order to let Lou Song, a talent with such a strong talent, 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 an energy storage lithium-ion battery with ultra-long life, high safety, and high storage capacity. In terms of battery grouping, we now have two options to choose from, namely SCM structure, and the PCM structure."

The SCM structure and the PCM structure respectively refer to series connection first and then parallel connection, and parallel connection first and then series connection.

The types of batteries are also divided into groups of small-capacity single batteries and single large batteries with larger capacities.

After Xu You finished the main content, a battery expert from Jijing University raised his hand and said:

"Professor Xu, I suggest to adopt the method of grouping small-capacity single batteries. Many practical applications have proved that in terms of safety, reliability and management, small-capacity single batteries are better than large-capacity batteries. have more obvious advantages.”

The expert cited some examples and explained the specific reasons through theory.

"That's right, this is also my suggested main direction of attack. But when everything is inconclusive, we still can't give up other possibilities."

In the process of consulting information before Xu You, he also knew that the method of grouping small-capacity single batteries is the best choice now.

The energy storage system including a Tesla electric vehicle is composed of nearly 10,000 small-capacity single batteries with a PCM structure.

However, this does not mean that it is the ultimate answer to the lithium battery energy storage system. The project team still needs to find a better energy storage solution through its own efforts.

For example, although the discharge capacity of the PCM structure battery pack of a certain Tesla is greater than that of the SCM structure, it does not consider the impact of different combinations of single cells in the battery pack on the performance of the battery pack.

This makes the life of the entire battery pack not very satisfactory, requiring the entire battery pack to be replaced every few years.

Of course, these problems are not limited to a certain brand, but widespread problems in the entire field.

And these problems must not appear in the power system.
