I Am the President of the University

Pennsylvania State University, referred to as psu, was founded in 1855. It has 23 "branch branches" and is one of the public ivy leagues. It ranks 78th in the world. Several majors are ranked among the top ten in the world, and engineering is strong.

It should be noted here that various "branch schools" often appear in beautiful countries.

For example, Penn State University here has twenty-three campuses, and the University of California has ten campuses.

Although these are all branch campuses, they are not affiliated, they are parallel and independent, and they all belong to the local state university system.

This kind of branch campus has a different meaning from the domestic branch campus, but it is translated into a branch campus in China.

Of the 23 Pennsylvania State University campuses, only the main campus in Park is among the top 100 universities in the world, and the other 22 campuses are relatively average.

On the other hand, the University of California is more powerful, with eight of its ten campuses ranked among the top 100 universities in the world.

The most powerful is of course the University of California, Berkeley, founded in 1868 and ranked among the top 10 universities in the world.

In addition, there are 3 branches ranked 10-20, the remaining 4 are within the 100th place, and only 2 branches are outside the 100th place.

In the cafe.

Bunir looked at Chen Hao curiously. Before Chen Hao returned to China, he was already well-known in the academic world of the beautiful country and was hailed as a genius at MIT.

What's even more powerful is of course the news that came out one after another after returning to China, which made many people stunned.

It turns out that I have underestimated this guy in the past.

"Principal Chen, do you want to sponsor the research on lithium-air batteries?" Seeing Chen Hao drinking coffee leisurely, Professor Bunier couldn't help but speak.

"I have this intention." Chen Hao nodded, but did not finish his words in one breath.

Hearing that it was just an intention, Bunir was a little disappointed and laughed at himself, "Yes, after all, lithium-air batteries are not as valued as all-solid-state lithium batteries."

Of course, what is more important is continued investment.

But this is definitely not a problem for Chen Hao. Although Bunir is a university professor, he still knows a little about Guanghua University and Chen Hao. The investment of tens of millions or hundreds of millions of dollars a year is not considered a big deal in the eyes of the other party. What.

Sensing the disappointment in Bunir's tone, Chen Hao smiled faintly and denied the other party: "No, no, no, I think lithium-air batteries are more promising than all-solid-state lithium batteries. It's just..."

Chen Hao changed the subject, looked directly at the other party, and asked: "Has Professor Bunier solved the four major technical problems currently faced by lithium-air battery technology?"

Lithium-air battery technology is certainly good and is known to both the scientific and industrial circles, but there are too many technical difficulties that cannot be overcome at all.

Mainly focused on four major aspects:

1. Lithium dendrite suppression of metallic lithium;

2. Li+ solid electrolyte with high ionic conductivity;

3. Interference from CO2 in the air: lithium carbonate cannot be recycled again;

4. The water and air of the air electrode are isolated from the metallic lithium negative electrode.

"I already have some ideas about one of them." When Bunir mentioned this, his eyebrows suddenly lit up.

"Which one?"

"the fourth."

Chen Hao was shocked. The most difficult of these four difficulties was the last one.

"The core technical difficulty of lithium-air batteries is the solid electrolyte membrane. The lithium-air batteries currently used in the scientific community are basically conductive glass films of inorganic ceramics such as LATP and LLZTO. However, the Li+ conductivity is lower than 0.001s/cm, which is brittle and It is hard, easy to break under pressure changes, and has poor contact with the metal lithium sheet, making it difficult to completely cover it.”

"Professor Bunir, how did you solve this problem?" Chen Hao's eyes became eager. \b

"I am studying a water-organic combined electrolyte. After li+ is discharged, it enters the water and dissolves into lithium hydroxide. It is very efficient and has a high probability of being able to isolate and prevent the contact between water and metal lithium sheets." Bunir is almost He spoke without pausing, obviously he had already drafted it.

"Then how to isolate the contact between water and lithium metal sheets?" Chen Hao asked.

Bunir said nothing, just blinked and smiled.

Chen Hao laughed out loud and slapped his head. He had really made a joke in a fit of enthusiasm.

Only a fool would say such a difficult technology.

"Professor Bunir, as long as you join Guanghua University, the school can support you in continuing your research on lithium-air batteries. You can consider it." Chen Hao seriously invited without thinking.

"Great!" Professor Bunier looked happy and couldn't help cheering, which even attracted the attention of the people at the table around him.

"Don't think about it. I'll take the nearest flight tonight to pack up my things. I'll come back as soon as I'm done with them." Professor Bunier was a little excited for a moment. Lithium-air batteries have been his hard work over the years, but no one is willing to support them. his research.

Fortunately, this problem was finally solved today.
