After the matter in the capital was over, Liu Qianqian made a special trip to Yang Chunhe's house to visit her before leaving. After all, this time the house matter was thanks to Yang Chuxi, otherwise, she would not know when she would be able to buy a suitable house.
Of course, in return, Liu Qianqian gave Yang Chuxi a piece of information about lithium-ion batteries. She reviewed the chemistry books she had read and found that there was something missing in the area of lithium-ion batteries.
Not only China, but also foreign countries have just started. The content is not very complete, because in her opinion, the lithium-ion batteries they are studying are really like children playing house. Thinking of Yang Chuxi, she prepared
got this gift.
Lithium-ion batteries have high energy density. Their volume energy density and mass energy density can reach 450W.h/dm3? and 150W.h/kg respectively, and they are still improving. The average output voltage is high (about 3.6V), which is Ni-
3 times that of i-MH batteries. And the output power is large. It has small self-discharge, high charging efficiency, long service life, and little environmental pollution. It is called a green battery, so lithium-ion batteries have great prospects in the outside world.
.
Yang Chuxi is a college student in the Chemistry Department of Peking University. It is said that his grades are good and he seems to be preparing for the postgraduate entrance examination. Lithium-ion batteries can be used as a topic for his graduate students. If he can research it, it will be beneficial to himself and the country. Of course, how will Yang Chuxi deal with that share?
Liu Qianqian will not force the information, but according to Uncle Yang and Yang Chuxi's temperament, they will definitely choose to hand it over.
As expected, when Yang Chuxi saw the information Liu Qianqian gave her, she was extremely shocked, especially since his research direction was also related to batteries. He naturally knew the importance of lithium-ion batteries, especially in the future.
The development prospects of lithium-ion batteries.
The information Liu Qianqian gave not only included a complete experimental design, but also a large number of chemical calculations. He knew that if it could be developed, their country would definitely lead the world in this area.
Seeing this, Yang Chuxi held back the shock in his heart, and told his father Yang Chunhe about the matter. After Yang Chunhe listened, he was silent for a while before speaking, "I will report this matter, and this information will be kept here for the time being.
As for the follow-up research and development issues, I think the higher-ups will have their own arrangements!"
Yang Chuxi nodded. He knew the priority of the matter, so naturally he would not be dissatisfied. Yang Chunhe nodded with satisfaction, locked the information in his cabinet, and prepared to report the matter to his leader early tomorrow morning.
...
"Classmate Liu Qianqian, do you really not need us to take you back to Five Counties?"
"Teacher Zhao, don't worry, I will get home safely and there will be no problems!"
Seeing this, they could only nod, but they didn't know that in fact, as early as when Liu Qianqian was preparing to return to the five counties, there were people secretly protecting Liu Qianqian on the train. Although Liu Qianqian had Sonic No. 1 on her body, Liu Qianqian was
The value shown by Qianqian, the leader did not dare to let Liu Qianqian act alone. They were all his own within a certain range, so they were so relieved to let Liu Qianqian go back alone, except of course the uninformed Teacher Zhao.
.
"Sister Sissi!"
"Sister Sissi!"
Just as Liu Qianqian was about to enter the train station, she suddenly heard a milky voice. Liu Qianqian turned around and saw that it was Pei Jianjun. The moment she saw Pei Jianjun, Liu Qianqian took a picture.
I slapped myself on the forehead. I was so busy during this period that I forgot to promise that I would visit the little guy. I hope the little guy won’t be angry!
"Sister Sissi!"
"Junjun, are you here to see your sister off?"
Pei Jianjun nodded, then pursed his lips, "Sister Qianqian means nothing!"
Liu Qianqian touched the little guy's head apologetically, "Junjun, I'm sorry, my sister was too busy, so I forgot. When my sister gets admitted to Beijing next year, I will definitely visit you, okay?"
The little guy's eyes lit up, "Really?"
"real!"
"Hook hook!"
"Okay, let's pull the hook!"
Liu Qianqian looked at Wang Zhenrong, "Aunt Wang, thank you for bringing Junjun to see me off!"
"We should be the ones thanking you!"
Wang Zhenrong had a good impression of Liu Qianqian in the first place. Later, when he learned that Liu Qianqian won the championship on behalf of the national team, he became even more fond of Liu Qianqian. Moreover, since his son liked this little girl so much, Wang Zhenrong would naturally unleash his greatest passion.
bona fide.
"Aunt Wang, I will definitely come to Beijing for the college entrance examination next year, and I will pay you a visit then!"
"waiting for you!"
Wang Zhenrong nodded, Liu Qianqian hugged the little guy, and then when the little guy was about to cry, he decisively entered the train station. Although he bought a lot of things, they all were mailed back, so Liu Qianqian's whole body was
With only a small backpack, I can be considered the most relaxed passenger.
Liu Qianqian looked at her seat number and successfully found her seat number in bus No. 7. Liu Qianqian took out a math book from her backpack, put the backpack behind her, and then sat there
Start reading in bed.
She was in a soft sleeper, and she was the only one in the room so far, which felt pretty good. When the train left and no one came to the room, Liu Qianqian knew that this might be a special arrangement from above.
Sissi didn't feel disgusted at all. She looked around, closed the door of the carriage, and began to read attentively. When she was hungry, she would take out some dried meat or snacks to feed her stomach. It was a very leisurely day.
On the other side of the carriage, Yu Che looked at the room in the middle with a curious face, and asked with some confusion, "Brother Mu, what do you think that little girl is? The two of us were asked to protect a little girl.
, and also asked you to come, could it be that you are a descendant of some big family?"
"That's not right. Even if you are a descendant of a big family, it's impossible for you to send us two here!"
Mu Hancheng had a cold face throughout the whole process and didn't say a word. It wasn't that he wasn't curious, but the duty of a soldier was to obey orders. When he saw the little girl in the photo, Mu Hancheng's heart skipped a beat.
Isn't this little girl the one he met in Harbin last year? His superiors actually asked him to protect her. From what he could tell, that little girl's skills were not simple. He couldn't tell who was protecting whom. Mu Hancheng glanced at Yu Che
.
"No, Brother Mu, what is your look like?"
Mu Hancheng remained silent and closed his eyes to rest. Yu Che opened the door and wanted to take a look. He was really curious. Before he could go out, Mu Hancheng's voice sounded coldly from behind.
"Don't mess with that little girl, you are no match for her!"
Yu Che looked in disbelief, "Brother Mu, are you kidding me? Although I am worse than you, I am still ranked third among our Falcons. Do you think I am better than that little girl?"
Mu Hancheng stopped talking, and Yu Che couldn't make up his mind for a moment, so he could only close the door. Although he didn't believe it, he thought that Brother Mu had never bothered to lie, so maybe that little girl was really a big shot.
Yu Che said that he was scared. The main reason was that the superiors only asked them to protect him secretly and not to be discovered. If this was really like what Brother Mu said, wouldn't it be embarrassing if they were discovered.
Although Mu Hancheng had been keeping his eyes closed, he was still guessing about Liu Qianqian's identity. The request from the superiors was that the little girl would not be allowed to be harmed at all, especially her head. This seemed like a strange order.
, but he got some clues, but he is not a very curious person, as long as he completes this mission!
Liu Qianqian's train trip was very smooth, and because there was no one in the carriage, Liu Qianqian's train trip was very comfortable. When she saw the familiar scenery, Liu Qianqian had never been as excited as she was at this moment.
She quickly packed her things and waited at the door of the carriage early. When the train stopped, the conductor opened the door. Liu Qianqian couldn't wait to get off the car. As soon as she got off the train, she saw Liu Chengshuan and Wang Cuiju in the station.
"Father, mother!"
Liu Qianqian ran over immediately, and Wang Cuiju hugged her daughter who ran over, "You're finally back. Girl, have you been playing wild outside and don't want to go home?"
"No, I miss you so much!"
"Just come back!"
Liu Chengshuan nodded. Although it was not as obvious as Wang Cuiju's expression, Liu Qianqian still saw the happiness in Liu Chengshuan's eyes.
