Chapter 260: School Beauty Song is indeed growing

The twilight was deep, and the low chirping of insects came from outside the window. The hustle and bustle of the day had completely disappeared at this point. The master bedroom was a bit dark, barely enough to see the general outline.

"Phew~"

Song Yao let out a slow breath, lying on her side. Through the faint light, she could see Xu Qingzhou's general outline. This was the second time she had woken up.

"This bad guy."

Hearing Xu Qingzhou's steady breathing, Song Yao couldn't help but mutter in a low voice, reaching out to poke Xu Qingzhou's forehead. She wasn't used to it, but this guy was sleeping very soundly.

No way, with an extra person on the bed, she couldn't roll around like before, always worrying that when she woke up, she would already be lying on top of Xu Qingzhou.

It made her look sexually frustrated.

Song Yao thought about the two of them lying together again.

Auntie Jia agreed immediately, saying she would find someone to install it in the next few days.

Read! {

"I'll call later." Xu Qingzhou nodded, brushing his teeth, and said: "Kyoto is actually hot in summer, it really should have an air conditioner."

Mix the modified silicon powder, conductive agent, binder, etc., in a certain proportion, add an appropriate amount of solvent, and stir thoroughly with a mixer to make a uniform negative electrode slurry.

Xu Qingzhou looked at the data chart on the computer and nodded slightly.

The bold are stuffed to death, the timid are starved to death—that's the logic.

Xu Qingzhou laughed dryly, went to the bathroom, came out, held his toothbrush, pressed it a few times, only to find the red light on. He simply waited for Song Yao to borrow her toothbrush.

Song Yao looked faintly at this thick-skinned guy. Hmph, sure enough, it was like this. She had already seen through Xu Qingzhou.

Song Yao didn't speak, keeping a heart. Based on her understanding of her boyfriend, since this person had moved into her room, he would definitely pester her and not leave. How could he be active in installing an air conditioner, waiting for her to drive him away? "After all, we can use that room as a guest room. If your parents come over, or my parents come over, they can all sleep there, glug glug~"

"Using libh4 for pre-lithiation of silicon negative electrode, the ICE has reached 89.1%, and the capacity retention rate after 100 cycles can still reach 83.6%, which is a big breakthrough compared to the first stage."

Professor Zhao said with a smile: "Thanks to the feedback you gave."

"Good morning."

However, it would be perfect when they were covered in the same quilt.

On the shelf next to the wardrobe, exquisite intimate clothing was drying.

"Hmm, good morning." Song Yao looked away with a guilty conscience. Nights were indeed prone to impulsiveness and softness. In a moment of carelessness, she fell into his trap and let him move into her room.

Putting the clothes into the washing machine, Xu Qingzhou went out and called Auntie Jia on the way, saying the weather was too hot and it was still necessary to trouble Auntie Jia to install an air conditioner.

Xu Qingzhou woke up at 7:30 AM, opened his eyes, stared blankly at the ceiling for a while, and then realized he was in Song Yao's room. Memories of last night came flooding back.

In fact, she had seen through Xu Qingzhou's little tricks many times, but she still couldn't help but "fall for it," pretending to be stupid and falling into his net.

After sighing, Xu Qingzhou stretched, tidied up the bed—two pillows, two quilts—it already felt like an old married couple.

!.

"Don't be polite, we should be the ones thanking you." Professor Zhao smiled, paused, and said: "I'll just watch from the side, you can ask me any questions anytime."

Xu Qingzhou pushed the door out happily. Song Yao was wearing a headband and brushing her teeth.

Only by making a battery yourself can you understand the process and various details.

Song Yao finished brushing her teeth. Seeing Xu Qingzhou raise the toothbrush in his hand to indicate it was out of power, she handed her toothbrush to him.

Preparing battery materials has a much higher risk factor than BIBQ crystals. Many raw materials are corrosive. Although the probability of explosion is relatively small, if operated improperly, splashing certain solvents onto the equipment would be very troublesome.

"Hands-on? Easy to talk about." Professor Zhao thought for a while and said directly: "We happen to be preparing to make Sample No. 33 of Group C, you try it."

Professor Zhao being able to agree immediately showed that he really trusted Xu Qingzhou. "Through your analysis results last time, we pre-added a certain amount of Li+ to the battery to compensate for the lithium loss caused by the formation of the SEI film destroyed by the volume effect of silicon. After several rounds of testing, it has been proven to effectively improve the initial Coulombic efficiency and battery life."

Xu Qingzhou planned to go to Professor Zhao and the others first in the morning to get the latest experimental data to adjust the model. Of course, he also wanted to see if there was a chance for hands-on practice.

A little scared, so he subconsciously refused, but his heart also carried a trace of expectation? Maybe because he liked someone, he always wanted to be close to him.

Song Yao's room was kept very tidy. The desk they bought had become a dressing table, with all kinds of cosmetics, hair ties, and charging cables.

Thinking about it, she felt it was funny. She had clearly said many times before that she wouldn't date in college. As a result, she was only a freshman, and she ran out to rent with Xu Qingzhou, and now they were even lying together... Sighing again, Song Yao closed her eyes, and her consciousness gradually fell into chaos.

"No problem."

In the optoelectronics laboratory, everyone was there. Wang Wei was doing data analysis in the office, and Hong Yayu was collecting sample data in front of the instrument with Gong Yunfei.

"Get up."

"In this hard drive, besides experimental data, there are also corresponding latest materials on battery pre-lithiation technology, electrolyte additive development, and silicon-carbon composite materials. You can take them back and look at them."

Professor Zhao Shengwen was looking at the latest experimental data with Xu Qingzhou.

"Thank you, Professor."

Sleeping very comfortably, enjoying the cool air conditioning, holding a soft little hand—beautiful.

The sound of washing up penetrated the wooden door and fell into the ears of the person daydreaming on the bed...

Xu Qingzhou quickly got the material list marked C201570633, put on a spare white coat, wore goggles, and the experiment began.

"Not yet."

Xu Qingzhou thanked him, paused, and said: "Professor, I've read a lot of lithium-ion battery materials these days, but I haven't practiced hands-on, here..."

Xu Qingzhou spoke eloquently.

Xu Qingzhou changed the toothbrush head and leaned to the side, watching Song Yao wash her face, "Did you call Auntie Jia?"

It would be even more beautiful if he could hug her to sleep.

"It's good if it can play a role." Xu Qingzhou said.

Whoa~ School Beauty Song is indeed growing.

"Didn't you sleep well?" Xu Qingzhou saw Song Yao's dark circles were a bit heavy.

The two finished breakfast and started to get busy with their own things.

"What do you think?" Song Yao said bitterly.

Professor Zhao took the hard drive out of the drawer and handed it to Xu Qingzhou.

The next day.

Song Yao was huddled at home reviewing, with an exam at 2 PM.

Methodical, every process was quite standard.

Professor Zhao was a bit surprised. It was too proficient. For example, in the weighing of silicon nanopowder, even he couldn't guarantee that he could take out the amount marked on the raw material table at once.

So, this is a genius? Drying and compaction... and positive electrode material assembly, which is assembling the positive electrode sheet, negative electrode sheet, and installing the Celgard separator. At this time, the basic structure of the battery cell had been formed.

Next, inject the ethylene carbonate electrolyte containing lithium hexafluorophosphate.
