I am devoted to scientific research, but you want to trick me into having a love relationship?

Chapter 624 Bah, they're all a bunch of old silver coins.

Inside the office.

Xu Qingzhou looked down at the test blueprints, while Zhao Shengwen was not in a hurry. He picked up the notebook next to him and began to study the experimental plan for the next few days.

Thirty minutes passed quietly.

Xu Qingzhou had already looked through all the drawings, and then pulled out a few XPS cyanide content analysis charts.

"Any progress?"

Looking at the several blueprints that Xu Qingzhou took out, Zhao Shengwen was a little surprised. They had been studying this for an entire afternoon, but they had no clue what to do. Xu Qingzhou had only looked at it for half an hour and found the problem.
"In the next few days, try focusing on the two variables: cyano coordination ability and sulfonic acid concentration."

Seeing everyone staring at him in surprise, Xu Qingzhou said, "I'm still not sure. I just feel that the coordination characteristic peaks of these two variables are a bit strange."

One of the researchers, who was wearing glasses, took the manuscript, looked at the data graph, and said, "The Zn coordination number of 6 seems to be correct."

"But I'm not sure about the Zn coordination number of the sample dropping from 6 to 4 in this band. It might just be a fluctuation due to impurities. We need to conduct experiments to find out for sure."

Xu Qingzhou said helplessly that he had read all the data and found many problems, but none of them were the main issues and could be gradually modified later. The only thing he found strange was the change in the data.

"it is good"

Zhao Shengwen nodded, "Then we'll conduct five sets of experiments to determine if there are any issues with the cyano group's coordination ability and the sulfonic acid group's concentration."

By the time Xu Qingzhou came out of the conference room, it was already quite dark.

He pushed open the office door and entered. Song Yao was typing away, writing her thesis.

"Are you alright?" Song Yao stopped what she was doing.

"Okay, all done. Let's go home."

The two packed their things and went downstairs.

In the parking lot, the two cars belonging to the family were parked together. Compared to the Jeep Wrangler, Xu Qingzhou's Audi, which he usually drove, looked like a small Calami.

Xu Qingzhou couldn't help but say, "This white sedan suits your style better."

"No."

Song Yao still prefers the wildness of off-road vehicles, with their spacious interiors and powerful engines.

"I know you like big ones."

"."

Song Yao's muscular arms were about to give way, but two people were passing by in the distance. After thinking for a moment, she put her hands on Xu Qingzhou's waist.

To outsiders, Song Yao was merely holding Xu Qingzhou's arm.

"Professor Xu, President Song."

"get off work?"

"Okay, Professor Xu, President Song, goodbye." After saying goodbye, the two researchers made their way off without disturbing Xu Qingzhou and Song Yao.

"Goodbye." Xu Qingzhou smiled, but secretly he gasped. Song Xiaohua's hand had already pinched his waist halfway, which was a little sore, but he didn't dare to show it.

"See if you dare to be so cheeky again."

At the end of November, Xu Qingzhou and his team were proceeding as usual, and before they had received any progress reports from domestic companies, Japan released some explosive news.

Toyota has developed a solid-state battery with a positive electrode volume capacity three times that of lithium-ion batteries and a volumetric energy density more than twice that of lithium-ion batteries.

With a capacity of 500 Wh/kg, electric vehicles equipped with this battery can achieve a range of up to 1000 kilometers. It can withstand dozens of charge-discharge cycles in a laboratory environment, and its durability is currently being verified.

Even though it's still only in the laboratory, this has already sent a shockwave through the battery industry.

It's worth noting that the energy density of the semi-solid-state battery samples from the Max Planck Institute is only 400 Wh/k. Although industrialization has been put on the agenda, the real solid-state battery is still only a PowerPoint presentation, and the technology is still being verified.

Xu Qingzhou and his team are currently working on lithium-ion batteries and lithium-sulfur batteries. The laboratory limit for traditional lithium-ion batteries is about 300-350 Wh/kg. For convenience, the samples Zheng Xu and his team made were actually semi-solid-state lithium batteries, with one electrode not containing liquid electrolyte and the other electrode containing liquid electrolyte.

In other words, this is the first high-performance solid-state battery to date.

The very next day, BYD officially released its latest research findings.

They have created a sulfide solid-state battery with an energy density of 520Wh/kg, a hybrid system of sulfides and oxides that balances ionic conductivity and chemical stability.

It is preparing to enter the pilot production line.

The battery industry was stunned.

Harvey's team at the Max Planck Institute is in a bit of a mess. They made a high-profile announcement of their progress a few days ago, but in just one month, they've been exposed twice.

The EU leadership was equally displeased. Just the day before, they were happy and hoped Japan would take the lead over China, but who could have imagined that they would be dealt a blow the very next day?

Of course, the most confused people were actually those in Ningde.

“The people of Biati are also a bunch of old silver coins.”

Chen Rongxuan couldn't help but complain.

He hasn't shown his face much lately, keeping a very low profile, but now he's suddenly given everyone a huge surprise.

He forgot that they had originally planned to give everyone a "surprise" in two months.

CEO Bai Mingzhe said, "After acquiring the technology from Xu Qingzhou and his team, the energy density of our solid-state batteries can reach 450Wh/kg."

Like BYD, they focus on sulfide solid-state batteries, but there are significant technological differences. BYD uses a sulfide + oxide composite solid-state electrolyte, while they choose a sulfide solid-state electrolyte.

"But it will take at least two more months to reach Biati's level."

Chen Rongxuan thought for a moment and said in a deep voice, "I suggest we recruit another 200 engineers. We must seize the high ground in technology."

Their all-solid-state battery research team currently has 800 people, which seems like a lot, but when divided among the upstream and downstream industrial chains, many links are already stretched thin in terms of manpower.

"Okay, I approve it."

CEO Bai Mingzhe nodded, stating that solid-state batteries, as the next generation of battery technology, are undeniably important and that it is essential to seize the initiative.

Peking University, several colleges.

Inside the office, the three men were leisurely drinking tea.

Meng Bin took a sip of tea, suddenly realizing that he used to only be able to sit at the children's table, and now he was able to drink tea with the big shots.

She used to be the one being taken care of by Senior Brother Su, but now she has become the backbone of her junior brothers and sisters.

Xu Qingzhou sipped her tea and chatted with Meng Bin about their research project.

Although Meng Bin is only 27 years old, he has already shown outstanding talent in the field of number theory, and can even be said to be quite famous in the mathematics community of Xia Country.

Gu Zhizhong looked at the composed young man opposite him and said, "As far as I know, several major events seem to have occurred in the battery industry, but you don't seem to be in any hurry at all."

"Why should I be in a hurry? Solid-state batteries are not our research goal."

Xu Qingzhou smiled and said calmly.

"You always seem so calm and collected. Your mindset is much more stable than ours, the old folks."

Meng Bin couldn't help but ask, "Have you ever thought about doing solid-state battery research directly? After all, BYD's breakthrough is inseparable from your technology."

If BYD and CATL obtained Xu Qingzhou's technology, they could take off directly in the field of solid-state batteries, assuming that Xu Qingzhou is indeed engaged in research in this area.

"I still believe that lithium-sulfur batteries have a brighter future."
