Chapter 487： mad scientist at penn

Pennsylvania State University, referred to as PSU, was founded in 1855. It has 23 "branch campuses", one of the public Ivy Leagues, and ranks 78th in the world university rankings. Several majors are ranked in the top ten in the world, and engineering is strong.

It should be noted here that there are often various "branch schools" in the beautiful country.

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 side by side, they are 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.

Among the 23 campuses of Penn State University, only the main campus, Parker, is among the top 100 universities in the world, and the remaining 22 campuses are relatively average.

On the other hand, the University of California is more powerful. Eight of the ten campuses have entered the top 100 universities in the world.

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

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

in the cafe.

Bunir looked at Chen Hao curiously. Before Chen Hao returned to China, he was already well-known in the academic circles of Beautiful Country and was known as a genius of MIT.

What is even more powerful is, of course, the continuous tossing after returning to China, which made many people stunned.

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

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

"I have this intention." Chen Hao nodded, but didn't say anything 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 important as all-solid-state lithium batteries."

Of course, more important is continuous investment.

It's just that this is definitely not a problem for Chen Hao. Although Bunier is a university professor, he still has a little understanding of Guanghua University and Chen Hao. The investment of tens of millions of dollars a year is not considered by the other party. what.

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

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

Lithium-air battery technology is of course good, and the scientific and industrial circles know it, but the technical difficulties are too many to be overcome at all.

Mainly focus on four aspects:

1. Lithium dendrite inhibition of metallic lithium;

2. Li+ solid electrolyte with high ionic conductivity;

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

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

"There's one I've got some eyebrows about." Bunir raised his eyebrows when he mentioned this.

"Which one?"

"the fourth."

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

"The core of the technical difficulties of lithium-air batteries is the solid electrolyte membrane. Now the lithium-air batteries used in the scientific community are basically conductive glass films of inorganic ceramics such as LATP and LLZTO, and the conductivity of Li+ is less than 0.001Scm, which is brittle and hard. It is easy to be broken under pressure changes, and it has poor contact with the metal lithium sheet, making it difficult to completely coat it.”

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

"I am studying a water-organic combined electrolyte. After Li+ is discharged, it dissolves into water and dissolves into lithium hydroxide. The efficiency is very high. He said without a pause, obviously he had already had a draft.

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

Bunir didn't speak, just blinked and smiled.

Chen Hao let out a laugh and patted his head.

Only a fool would say such a difficult technique.

"Professor Bunnier, as long as you join Guanghua University, the school can support you to continue your research on lithium-air batteries, you can consider it." Chen Hao did not think about it and invited him seriously.

"That's great!" Professor Bunier had a happy expression on his face, couldn't help cheering, and even attracted the attention of the people around the table.

"Don't think about it, I'll take the latest flight tonight to pack my things, and come back immediately after I've dealt with it." Professor Bunnier was a little excited for a while. Lithium-air batteries have been his hard work over the years, but no one is willing to support them. his research.

Fortunately, today finally solved the problem.

In the end, he was still a little uneasy and asked Chen Hao.

"President Chen, this lithium-air battery will be a huge investment, and... it may not be successful."

"It's okay, it's hard to say anything else, but money is just a number to me." Chen Hao shook his head and smiled.

Lithium-air battery technology, even if it has a 10% success rate, is worth trying, not to mention that Professor Bunnier alone is worth a 15% success rate, and a complete team should be able to break through 20%.

"call--"

With Chen Hao's assurance, Bunir was relieved, gasping for breath, as if he had been saved from drowning.

Chen Hao stood up and stretched out his hand to the other side.

"Welcome to Guanghua University!"

...

A few minutes later.

Seeing Bunir hurriedly returning to the hotel, Chen Hao looked thoughtful.

old technologies, maturation and decline;

New technology, birth and twists and turns.

Can lithium-air batteries be developed?

He didn't know, even if it was a gamble.

"Anyway, I'm not short of it is nothing more than a few hundred million, billions of dollars." Thinking of this, Chen Hao was a little excited.

This amount of money is not worth mentioning to him. In general, the prospect of lithium-air batteries is still good.

On the other hand, this Professor Bunier may have no problem with his ability, but is he trustworthy?

I took out my phone and checked the time, it was 11 am, 10 pm ET.

Made a phone call to an old acquaintance.

"Hey, old Chen, what's the matter?"

Cao Lihao's voice came from the phone. This time it was rare that there was no electronic sound from the other party. Chen Hao raised his brows.

"Rat, do you have any friends at Penn Park Park?"

"Yes, what's wrong?"

"Help me inquire about someone."

"Who?" Cao Lihao asked curiously.

"A professor named Bunier, help me find out about this person's character and reputation." Chen Hao said after thinking for a while.

Even if the other party's character and reputation are not good, he will still use him.

However, if the ability and character are the same, the treatment and emphasis will be different.

"Okay, no problem. What else is there, I have to study!" Cao Lihao complained.

"Who is studying? Is your new girlfriend nickname?" Chen Hao teased.

"gun!"

"Hang up, I'll tell you when there's news."

After arranging things, Chen Hao was relieved, thinking about this matter.

A little dazed for a while.

He whispered to himself:

"Is the era of lithium-air batteries coming?"

I am the president of the university https://
