Chapter 604

Oxford has a temperate maritime climate, with a relatively small temperature difference between the four seasons; winter is actually quite foggy and rainy, and November is just about one of the wettest months of the whole year in Oxford. It was only afternoon, and it was already gray and gloomy, with mist floating in the air.

The damp, cold air crept into his collar, and Xu Qingzhou couldn't help but tighten it, "This damn weather in Europe... it's still more comfortable staying in Xia Nation."

He found New College according to the route in his memory.

In his previous life, because he participated in an exchange, he had stayed here for two months, and he had long since become familiar with the place.

Oxford University is the oldest university in the world, with a history of over 800 years; walking on the streets, one can indeed feel the weight of history.

"Oxford's ancient stone walls, MIT's steel megastructures, and Jingda's Yan Garden autumn scenery—they each have their own characteristics, I suppose."

Xu Qingzhou turned right at the intersection of Broad Street and Catte Street, entered a narrow cobblestone road, and could vaguely see the Gothic stone archway of New College.

Oxford University has 39 colleges,

but they are different from the ones in the country.

Some colleges only recruit graduate students, while some colleges have no students at all, only fellows, such as All Souls College, Oxford.

In addition, Oxford University also has over 100 libraries, with an astonishing collection of books.

Xu Qingzhou found the seminar room for the group discussion according to the road signs.

Professor Harvey stood at the entrance, smiling and reaching out his hand: "Professor Xu, welcome. The report this morning was very brilliant."

"Thank you, I am very much looking forward to seeing your results."

Xu Qingzhou smiled modestly and greeted the other party.

"I guarantee you won't have made the trip in vain."

Professor Harvey made a gesture of invitation.

Xu Qingzhou walked into the auditorium and realized there were quite a lot of people; over 100 condensed matter physics scholars and industry experts from all over the world were sitting in the small auditorium. Seeing Xu Qingzhou walk in, many people nodded slightly to greet him, and he responded with a smile.

"Professor Chen, I don't seem to have seen you these past few days." Xu Qingzhou's gaze quickly fell on the face of an Asian person, and he sat down beside him.

An old acquaintance, Chen Zhang Rongxuan, the chief scientist of CATL.

It is a global phenomenon for leading enterprises to participate in academic report meetings; after all, this is a good opportunity to show their faces and promote cooperation.

"I was still in London for a meeting yesterday and rushed over specially today."

Chen Zhang Rongxuan glanced at Professor Harvey on the stage and smiled lightly: "Although this group of guys from the Max Planck Institute is very arrogant, they have nothing to say when it comes to technology. To be honest, I am quite looking forward to what new technology they can bring."

"I heard your sodium-ion battery experiment was successful, and the energy density has already reached 200 Wh/kg. Congratulations, Professor Chen."

"A small breakthrough, not worth mentioning."

Chen Zhang Rongxuan shook his head: "The data given by the Max Planck Institute says their lithium-metal solid-state battery energy density can theoretically reach 500 Wh/kg."

CATL's technical direction is different from the Max Planck Institute's; sodium-ion batteries, structural innovation (CTP technology), and high-energy-density material systems are already at the forefront of the world.

The Max Planck Institute, on the other hand, is working on lithium-metal solid-state batteries, researching sandwich solid-state electrolytes, starting from lithium dendrites.

Xu Qingzhou said: "But the lithium dendrite problem is not easy to solve."

True, the theoretical energy density reaches 500 Wh/kg, but if the lithium dendrite problem isn't solved, it's all useless. For example, lithium-sulfur batteries also have a theoretical energy density of over two thousand, but why can't they be popularized? It's because there are too many problems.

Chen Zhang Rongxuan was noncommittal; lithium dendrites are a big obstacle, and things like theoretical energy density are just fake tricks used to cheat some investment.

He didn't feel much pressure; in their laboratory's latest experiment, the battery's energy density had already reached 300 Wh/kg, and this was solid data.

A dozen more people entered the auditorium, and Professor Harvey didn't waste time; he went on stage and simply expressed his welcome to everyone for coming.

After saying a long string of things, he changed the subject and continued to smile: "Alright, facts have proven that compared to listening to me give these welcoming remarks, everyone might want to see our experimental results more."
