Chapter 260 The school beauty of Song Dynasty is indeed growing
The dusk is deep, and there are a few low sounds of insects outside the window. The hustle and bustle of the day has completely disappeared at this time. The master bedroom is a little dark, and you can barely see a person. perhaps.
“Hoo~”
Song Yao exhaled slowly, turned sideways, and could see the general outline of Xu Qingzhou in the faint light. This was the second time she woke up.
“This bad guy.”
Hearing Xu Qingzhou's steady breathing, Song Yao couldn't help but murmured in a low voice and reached out to poke Xu Qingzhou's forehead. She didn't like it, but this guy slept soundly.
I can't help it. With one more person on the bed, I can't roll around like before. I'm always worried that when I wake up, I will be lying on Xu Qingzhou.
It seems like she is not satisfied with her desires.
Song Yao thought about two people lying together again.
Actually, she had clearly seen Xu Qingzhou's little tricks many times, but she still couldn't help but "fell", pretended to be stupid, and fell into his trap.
I was a little scared, so I subconsciously refused, but I also had a little expectation in my heart?
Maybe it’s because you like someone and always want to be close to him.
I think it’s funny when I think about it. I’ve said many times before that I don’t want to fall in love in college. As a result, when she was just a freshman, she ran out to share a room with Xu Qingzhou, and now they are even lying together.
Exhaling again, Song Yao closed her eyes, and her consciousness gradually fell into chaos.
The next day.
Xu Qingzhou woke up at 7:30 in the morning, opened his eyes and stared at the ceiling for a while, then realized that he was in Song Yao's room, and the memories of last night came flooding back.
I slept quite comfortably, enjoying the cool air conditioning and holding my soft little hands, it was wonderful.
It would be even better if I could sleep in my arms.
This is the principle of supporting the bold to death and starving the timid to death.
Song Yao's room was kept neatly. The desk they bought became a dressing cabinet with various cosmetics, hair ropes, and charging cables.
On the shelf next to the wardrobe, delicate underwear is hanging.
Oh~
Song school beauty is indeed growing up.
The sound of washing penetrated the wooden door and fell into the ears of the daydream person on the bed. .
“Get up.”
After sighing, Xu Qingzhou stretched and made the bed. With two pillows and two quilts, it already felt like an old couple.
However, when you are covered in a quilt, it will be perfect.
Xu Qingzhou happily opened the door and went out. Song Yao was wearing a hairband and brushing her teeth.
"Good morning."
"Well, good morning." Song Yao looked away guiltily. She was indeed easily impulsive and soft-hearted at night, and accidentally fell into his trap, causing her to He moved into his own house.
"Did you not sleep well?" Xu Qingzhou saw that the dark circles under Song Yao's eyes were a bit heavy.
“What do you think.” Song Yao said bitterly.
Xu Qingzhou sneered, went to the bathroom, came out, took a toothbrush, pressed it a few times, and then realized that the red light was on, so he simply waited for Song Yao to borrow her toothbrush.
After Song Yao finished brushing her teeth, she saw Xu Qingzhou raised the toothbrush in his hand to indicate that the battery was out, and handed her toothbrush over.
After changing the toothbrush head, Xu Qingzhou leaned aside and watched Song Yao wash her face, "Did you call Aunt Jia?"
"Not yet."
"I'll call you later." Xu Qingzhou nodded, brushed his teeth, and said, "It's actually still hot in Kyoto in summer, so we should install an air conditioner."
Song Yao didn't say anything and kept an eye on her. Based on her understanding of her boyfriend, he would definitely stay in his room after he moved to her room. How could he proactively install the air conditioner and wait for her to evict him? "After all, we can use that room as a guest bedroom. If your parents come over, or my parents come over, you can sleep there, Gululu~"
Xu Qingzhou said confidently.
Song Yao looked at this thick-skinned guy indifferently, hum, it was indeed like this, she had already seen through Xu Qingzhou.
After the two had breakfast, they began to do their own things.
Xu Qingzhou plans to go to Professor Zhao and his team in the morning to get the latest experimental data and adjust the model. Of course, he also wants to see if there is any opportunity for practical operation.
Only by making a complete battery yourself can you understand the process and various details.
Song Yao is studying at home and has an exam at 2 p.m.
After stuffing the clothes into the washing machine, Xu Qingzhou went out. On the way, he called Aunt Jia and said that the weather was too hot and he had to trouble Aunt Jia to install an air conditioner.
Aunt Jia agreed and said she would find someone to install it within a few days.
Everyone is here in the optoelectronics laboratory. Wang Wei is doing data analysis in the office, and Hong Yayu and Gong Yunfei are collecting sample data in front of the instrument.
Professor Zhao Shengwen looked at the latest experimental data with Xu Qingzhou.
“Using LiBH4 to prelithiate the silicon anode, the ICE has reached 89.1%, and the capacity retention rate after 100 cycles can reach 83.6%, which is a huge breakthrough compared to the first stage.”
Xu Qingzhou looked at the data chart on the computer and nodded slightly.
Professor Zhao said with a smile: "Thank you for the feedback there."
"Based on your last analysis results, we pre-added a certain amount of Li+ to the battery to make up for it. The loss of lithium caused by the formation of the SEI film destroyed by the volume effect of silicon has been proven to effectively improve the first Coulombic efficiency and battery life. "
"It works." Xu Qingzhou said.
Professor Zhao took out the hard drive from the drawer and handed it to Xu Qingzhou.
"In addition to experimental data, this hard drive also contains the latest information on battery pre-lithiation technology, electrolyte additive development and silicon-carbon composite materials. You can take it back and have a look."
Thanks to Xu Qingzhou , paused, and then said: "Professor, I have read a lot of information on lithium-ion batteries these days, but I haven't practiced it yet. Here"
"Practical practice? Easy to say." Professor Zhao thought for a while , said directly: "We are just about to make sample No. 33 of Group C. Come and try it."
"Thank you, Professor."
Preparing battery materials has a much higher risk factor than BiBQ crystals , many raw materials are corrosive, and although the probability of explosion is relatively small, if you are not careful, it will be very troublesome to splash certain solvents on the equipment.
Professor Zhao's ability to agree immediately shows that he really trusts Xu Qingzhou.
“You’re being polite, it’s us who should thank you.” Professor Zhao smiled, paused, and said, “I’ll be watching from the side. If you have any questions, just ask me anytime.”
"No problem."
Xu Qingzhou quickly got the bill of materials marked C201570633, put on his spare white coat and goggles, and the experiment began.
Mix the modified silicon powder, conductive agent, binder, etc. according to a certain proportion, add an appropriate amount of solvent, and stir thoroughly with a mixer to make a uniform negative electrode slurry.
Methodical and every process is fairly standard.
Professor Zhao was a little surprised. He was so skilled. For example, in weighing silicon nanopowder, even he could not guarantee that he could take out the amount marked on the raw material table at one time.
So, this is genius?
Drying and compaction.
Assemble with the positive electrode material, that is, the positive electrode piece, the negative electrode piece, and the installation of the Celgard separator. At this time, the basic structure of the battery core has been formed.
Next, an ethylene carbonate electrolyte solution containing lithium hexafluorophosphate is injected.
