Chapter 605

Small auditorium.

Everyone was discussing in a few words, and Professor Harvey on the stage was answering questions from time to time.

Taking advantage of the gap, his gaze looked toward Xu Qingzhou, who had been silent: "Professor Xu, do you have any brilliant insights?"

For some reason, he felt that this 23-year-old young man gave him the most sense of crisis.

Xu Qingzhou tapped his pen tip and said in a deep voice: "Niobium (Nb) doping may lead to lithium-niobium alloying side reactions, accelerating electrolyte decomposition. In-situ Raman spectroscopy only verified 800 hours of cycling; how can you prove the chemical inertness of this material in practical applications?"

"A very sharp question."

Professor Harvey nodded; this young man before him was indeed not simple, finding the key problem at once. He said calmly: "We have already detected the stability of the interface passivation layer through synchrotron X-ray absorption spectroscopy (XAS), but... the development of technology takes time, and long-term dynamic evolution still needs further verification. We have already planned to launch a 10,000-hour accelerated aging test with the Argonne National Laboratory."

"The sandwich structure requires a layer thickness error of <1 micron; the precision of current mainstream magnetron sputtering equipment seems unable to meet the process requirements."

Xu Qingzhou raised his second point of doubt.

"We use distributed deposition and laser calibration technology, and currently we have been able to compress the error to 2 microns. That's right, there is still a distance to industrialization standards."

Professor Harvey said with a smile: "We have already jointly developed sub-micron deposition equipment with the German company Zeiss, and we will be able to complete the pilot test next year."

A low gasp of surprise sounded at the scene again.

An expert said: "The halide electrolyte layer (LTLC) dynamically decomposes dendrites into nanospheres, synchronously repairing interface cracks. If I'm not mistaken, this is an extension of XCT tomography technology."

"Yes, here, I must introduce the key technology to everyone, which I have named the 'sandwich' structure framework. First, it is necessary to introduce a niobium-doped interface layer..."

On the stage, Professor Harvey was introducing the advancement of the achievement technology.

Off the stage, scholars were earnestly looking at the data on the stage, and industry enterprise representatives also made plans, starting to contact their headquarters to discuss countermeasures.

Among them was Chen Zhang Rongxuan.

He had already signaled his assistant to synchronize the situation here to headquarters; this news was too shocking.

Actually, there was nothing to discuss; in the face of such absolute technical superiority, there is usually only one word: buy.

But...

Chen Zhang Rongxuan couldn't help but feel a bit bitter in his heart; nowadays, Europe and the United States are both carrying out technical blockades, and such advanced technology, I'm afraid, will not be sold easily.

Even if it is finally sold, they will definitely bleed heavily.

Damn, things had only just improved for a few years, and now the pressure is on again.

When they discussed domestic and foreign advantages in the past, they actually had some psychological preparation that they wouldn't always occupy the dominant position.

After all, the West has the first-mover advantage, such as owning patents for various sophisticated equipment, which is equivalent to holding the source. Although the country also has alternative equipment, the precision and performance have not developed.

It's just that I didn't expect this day to come so quickly.

Chen Zhang Rongxuan sighed, cast aside distracting thoughts, turned his head to look at Xu Qingzhou, who had a calm expression on the side, "Professor Xu doesn't seem that surprised."

"Actually, I'm quite surprised too."

Xu Qingzhou told the truth; before coming, he had roughly guessed that Professor Harvey and the others should have had interim results, but he still didn't expect the progress to be so great.

Four or five years ahead of peers.

Is his role as a catfish that big?

Chen Zhang Rongxuan couldn't help but say: "Domestic battery manufacturers are going to have a headache again. Although I don't know the core experimental data of other domestic enterprises, there is definitely a gap compared to this."

"This group of guys from the Max Planck Institute really has something."

Xu Qingzhou agreed very much: "Actually, the data from our Kyoto Institute is also not bad."

However, the assistant said something in Chen Zhang Rongxuan's ear. After listening, Chen Zhang Rongxuan greeted Xu Qingzhou: "Professor Xu, I still have something to do, I have to leave for a while."
