Chapter 197: Only through familiarity

In the living room, Er Miao jumped back and forth on the luggage bags, having a great time.

"Stupid cat," Xu Qingzhou complained, stood up, packed luggage with Song Yao, and then returned to their respective rooms.

Xu Qingzhou didn't have much stuff. In half an hour, he had finished most of it. One-third of the large wardrobe remained empty, looking desolate. "Should I buy some clothes?"

Thinking about it, he shook his head, thinking these clothes were just right, so as not to be troublesome when moving to the room next door.

The two rooms were opposite each other, and one could see the other room while standing at the door.

Seeing that there were still two large bags of unpacked luggage in Song Yao's room, Xu Qingzhou walked over with a smile, "Do you need me to help..."

"Bang~"

Song Yao's bedroom door closed.

"No need!" An angry girl's voice came from the room.

Read! {

3 hours later, the seed crystal was introduced, allowing the melt to gradually crystallize on the seed crystal and grow into a single crystal.

Xu Qingzhou had no choice but to continue guarding here. During the crystal growth process, the early stage is relatively fragile. If a problem occurs in a certain place, hours of effort will be wasted.

Seeing Wang Wei and the others busy, he had time to come over and talk to Xu Qingzhou: "Little Xu, are you looking at information on lithium-ion solutions?"

The next day, Xu Qingzhou got up early. Song Yao was even earlier than him, already sitting at the table reading. After Xu Qingzhou finished washing up, the two went to the cafeteria for breakfast together, then went their separate ways, starting a busy day of life.

"..."

Xu Qingzhou didn't continue to ask. If he teased her any further, he might get beaten up. Having nothing to do, he cleaned the living room and then leaned on the sofa to read.

After the crystal was formed, the remaining time became a boring wait, so Ren Xiaoling went back to revise her thesis first.

Wednesday passed in a flash.

Xu Qingzhou thought that if his mentality wasn't good, he would have been depressed long ago from those repetitive experiments.

Heh, I knew I would be rejected, but I just wanted to ask.

Gong Yunfei was full of admiration.

Professor Zhao instructed: "Give Little Xu a copy of the thesis and data we prepared."

Xu Qingzhou knew this stuff. Lithium-ion dendrites formed by the uneven deposition of lithium ions on the surface of the negative electrode, whether it is dendritic lithium dendrites or metallic lithium with different morphologies appearing on the negative electrode side, are collectively called lithium plating.

At 5:30 PM, the two went out, finished eating at the Nongyuan restaurant, Song Yao went to class, and Xu Qingzhou went to the library to read.

"Right, I plan to understand it." Xu Qingzhou nodded.

Professor Zhao Shengwen waved his hand and said: "It's just some information. I still trust your character, kid."

Gong Yunfei said: "Conducting cyclic voltammetry tests on silicon-based composite negative electrode materials at the electrification workstation next door."

Xu Qingzhou smiled modestly. Both sides were busy, and everyone soon began to focus on their own work.

Hiss~ not to mention, the style is actually quite good.

"Results so quickly?" Xu Qingzhou was surprised.

Hong Yayu nodded, which counted as greeting Xu Qingzhou.

"Alright." Gong Yunfei answered.

Before the crystal is fully formed, temperature gradients, melt flow rates, and pulling rates and other detailed parameters must be controlled, so Xu Qingzhou must stay in the laboratory all the time. Ren Xiaoling faithfully followed Xu Qingzhou, staring at the furnace without blinking, feeling incomparably confused. For example, the pulling rate and such, the junior didn't follow the plan, but adjusted it on his own after looking at the parameters.

Gong Yunfei sighed: "It's still your mentality that's good, Junior." He touched his nose. Heaven can testify, he really just wanted to help. Now it's good, the pink thing is lingering in his mind.

Xu Qingzhou skillfully put the evenly mixed raw materials into the crucible for melting.

The growth of lithium plating is one of the factors affecting the safety and stability of batteries.

Regarding her confusion, Xu Qingzhou only had four words: Only through familiarity.

Professor Zhao asked everyone to go through the information again, wanting to see if there were any problems with the steps first.

At noon, Professor Zhao Shengwen and Wang Wei returned, but unfortunately, they had to test for another day to find the result.

"Professor." Gong Yunfei responded.

Professor Zhao smiled and said: "This thing is definitely a research hotspot for a period of time in the future. If you are interested... that, Little Gong."

In other words, experience and knowledge reserves are very important. For example, he knows whether to increase the temperature just by looking at the state of the crystal. After all, the growth rates at both ends of the polar axis are very different, which is very likely to cause the crystal morphology to deviate from the equilibrium state and form defects.

Gong Yunfei was as enthusiastic as ever: "Junior, preparing to make the fourth sample?"

In the optoelectronics laboratory, Hong Yayu was using a scanning electron microscope (SEM) to detect sample fragments, and Gong Yunfei followed along to record.

Xu Qingzhou headed straight for the optoelectronics laboratory. The jet lag was adjusted, and it was time to do experiments. Today was mainly to prepare 2.0mm BIBO crystals, which was expected to take at least 24 hours.

At 11:00 AM, crystal growth entered a stable period. Xu Qingzhou wasn't that tense and chatted with Gong Yunfei, who was free on the side, "Where are Professor Zhao and Wang Wang Shixiong Wang?"

!.

He borrowed a piece of information on lithium-ion solutions from Senior Sister Hong Yayu to supplement his knowledge in this area.

Coughing dryly, Xu Qingzhou straightened his expression and knocked on the door again, "Really don't need me to help you?"

At the tightly closed door, Xu Qingzhou's expression was strange. If he wasn't mistaken, just now on the bed, there were pieces of small... intimate clothing?

"Participating in a report meeting in Jianqiao... Junior, I'm already tired of saying the word 'awesome'."

Strive to get it done tomorrow morning and put it into the experiment.

The BIBO crystal preparation steps didn't change much. It still needed to be mixed according to the stoichiometric ratio BIO: BO=1:3, but the amount of raw materials needed to be controlled to ensure that the grown crystal could meet the experimental requirements after cutting.

Gong Yunfei shook his head and smiled bitterly: "It's just a discarded sample. There is too much lithium plating, and it can't be used at all. They just want to check where the problem lies."

"Thank you, Professor." Xu Qingzhou was a bit surprised. This information was all key laboratory secrets.

"The process of failure is the process of accumulating experience. Maybe there will be progress soon." Xu Qingzhou smiled and comforted.

Xu Qingzhou said: "Right, the experiment has been stopped for many days. If I don't come, the progress will not be able to keep up."

Ren Xiaoling came quite early, waiting for Xu Qingzhou downstairs at the experimental building, and the two entered the building together.

Er Miao jumped to Xu Qingzhou's side and lay down to sleep, its furry tail sweeping across his legs from time to time.

Many years later, this problem has been effectively solved, but unfortunately, Xu Qingzhou hasn't studied it in depth and can only wait until he has time later to tinker with it.

Besides thinking highly of Xu Qingzhou, he also had some selfishness. This project experiment will inevitably require data analysis in the future, and maybe there will be times when he needs to trouble this kid.

At this time, Xu Qingzhou also guessed some of Professor Zhao's thoughts. If there was anything within his power, he was very willing to help.

"Junior, the information." Gong Yunfei copied the experimental information to Xu Qingzhou.

"Okay, thank you, Wang Wang Shixiong."
