I Am the President of the University

Pennsylvania State University, or psu for short, was founded in 1855. It has 23 "branch campuses", one of the public Ivy League, and is ranked 78th in the world. It has several majors in the top ten in the world, and is relatively strong in engineering.

　　 Need to pay attention to here, there are often various "branch schools" in the beautiful country.

　　 For example, Penn State University here has 23 campuses, and the University of California has 10 campuses.

　　 Although these are all branch campuses, they are not subordinate, they are side by side, they are independent, and all belong to the local state university system.

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

　　 There are 23 branches of Pennsylvania State University. Only the main campus, Parker, is among the top 100 universities in the world. The other 22 branches are relatively average.

　　 The University of California is more powerful. Eight out of ten campuses are among the top 100 universities in the world.

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

In addition to 　　, there are 3 branch schools ranked 10-20, the remaining 4 are within the 100, and only 2 branch schools 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 the beautiful country and was hailed as a genius of mit.

　　 What's even more powerful is of course the turmoil after returning home, which made many people dumbfounded.

　　 I had already underestimated this guy in the past.

　　 "President Chen, do you want to sponsor research on lithium-air batteries?" Seeing Chen Hao sipping coffee leisurely, Professor Buniel couldn't help but speak.

　　 "There is this intention." Chen Hao nodded, but didn't say anything to death.

　　 Hearing it was just an intention, Buniel 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, more importantly, continuous investment.

It’s just that this is definitely not a problem for Chen Hao. Although Bunir is a university professor, he still has a little understanding of the affairs of Guanghua University and Chen Hao. The investment of tens of millions of dollars a year is not counted in the eyes of the other party. what.

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

　　 Chen Hao turned around, looked directly at the other party, and asked: "It's just that the four major technical problems currently faced by lithium-air battery technology are solved by Professor Buniel?"

Li-air battery technology is of course good, as the scientific and industrial circles know it, but there are too many technical difficulties to overcome.

　　 is mainly concentrated in four aspects:

　　 1. Lithium dendrite suppression 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 is one I already have a little eyebrow." Buniel mentioned this, and suddenly his eyebrows danced.

　　 "Which one?"

"the fourth."

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

"The core of the 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 membranes of inorganic ceramics such as latp and llzto, and the li+ conductivity is lower than 0.001s/cm, which is brittle and Hard, easy to break under pressure changes, and poor contact with the metal lithium sheet, it is difficult to completely cover."

　　 "Professor Buniel~www.readwn.com~How did you solve this problem?" Chen Hao's eyes were eager.

"I studied a water-organic combined electrolyte. After li+ is discharged, it dissolves into lithium hydroxide in water. The efficiency is very high. There is a high probability that it can isolate the water and prevent the contact between the water and the lithium metal sheet." Speaking without pause, it is obvious that there is an early draft.

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

　　 Buniel didn't speak, just blinked and smiled.

　　 Chen Hao let out a laugh and slapped his head. He really made a joke for a while.

　　 Such a difficult technique, only a fool would say it.

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

　　 "That's great!" Professor Buniel was beaming and couldn't help cheering, and even attracted the attention of the people around him.

"Don't think about it. I will take the most recent flight back tonight to pack my things, and I will come back immediately after handling it." Professor Buniel was a little excited for a while. The lithium-air battery was his painstaking effort over the years, but no one was willing to support it. His research.

　　 Fortunately, this problem was finally solved today.
