Chapter 624: Pfft, They Are All a Bunch of Old Silver Coins

Inside the office.

Xu Qingzhou looked down at the test diagrams one by one. Zhao Shengwen wasn't in a hurry either; he took the notebook beside him and studied the experimental plan for the next few days.

30 minutes passed quietly.

Xu Qingzhou had already looked through all the diagrams and then pulled out a few XPS cyano-content analysis charts from them.

"Got a clue?"

Looking at the diagrams Xu Qingzhou took out, Zhao Shengwen was a bit surprised. They had been studying this thing for an entire afternoon but had no ideas at all. Xu Qingzhou found the problem after looking at it for only half an hour?

"These few days, you guys first try from the two variables of cyano-coordination ability and sulfonic acid group concentration."

Seeing everyone looking at him in surprise, Xu Qingzhou said: "Still not sure, just feel that the coordination characteristic peaks of these two variables are a bit strange."

One of the researchers wearing glasses took the manuscript, looked at the data chart, and said: "Zn coordination number being 6 seems to be no problem."

"But in this band, the sample's Zn coordination number dropped from 6 to 4. I'm also not sure; perhaps it's just debris fluctuation. Specifically, it still needs you guys to conduct experiments."

Xu Qingzhou said helplessly. He finished reading all the data, and there were problems in many places, but none were the key points. Subsequent modifications could be made slowly. The only thing he felt was that the data change here was a bit strange.

"Good."

Zhao Shengwen nodded, "Then do 5 groups of experiments separately to determine if there is a problem with the cyano-coordination ability and sulfonic acid group concentration."

By the time Xu Qingzhou came out of the conference room, the twilight was already quite deep.

He pushed the door into the office, and Song Yao was typing away, writing a paper.

"Nothing else?" Song Yao stopped her movements.

"Hmm, finished, let's go, go home."

The two tidied up their things and went downstairs.

In the parking lot, the two cars at home were parked together. Compared to the Wrangler, the Audi that Xu Qingzhou usually drove looked like a small 'kara-mi' (insignificant).

Xu Qingzhou couldn't help but say: "This white small sedan matches your temperament better."

"Don't want it."

Song Yao still liked the wildness of the off-road vehicle, with large space and sufficient horsepower.

"Know you like big ones."

"..."

Song Yao's 'Kirin arm' was about to be unable to restrain itself, but seeing two people passing by in the distance, she thought about it and put her hand on Xu Qingzhou's waist.

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

"Professor Xu, Song Zong."

"Off work?"

"Hmm, Professor Xu, Song Zong, goodbye." The two researchers finished greeting and slipped away directly, not disturbing Xu Qingzhou and Song Yao.

"Goodbye." Xu Qingzhou had a smile on his face, but privately he took a cold breath. School Beauty Song's hand had already twisted half a circle on his waist, which was a bit sour and refreshing, but he didn't dare to show it.

"See if you dare to be mouthy again..."

At the end of November, Xu Qingzhou and the others were steady and conventional. Before they waited for the progress report from domestic enterprises, the Japanese side was the first to release explosive news.

Toyota developed a solid-state battery with a positive electrode unit volume capacity 3 times that of lithium-ion batteries, and the volume energy density reached more than 2 times.

500Wh/kg, the electric vehicle equipped with this battery can have a range of up to 1000 kilometers, and it can withstand dozens of charge-discharge cycles in a laboratory environment, and durability is under verification.

Even if it still stayed in the laboratory, this was directly releasing a shockwave to the battery field.

You know, the energy density of the semi-solid battery samples at the Max Planck Institute was only 400Wh/kg. Although industrialization had been put on the agenda, the real solid-state battery also stopped at PPT, and the technology was still under verification.

Xu Qingzhou and the others were currently doing lithium-ion batteries and lithium-sulfur batteries. The laboratory limit of traditional lithium-ion batteries was about 300-350Wh/kg. ===== CHAPTER 625 =====
