Chapter 307 Inorganic Materials Science
"Linlin, what's the matter, you're not feeling well? I'll ask the teacher for leave for you." Beside him, a handsome boy asked gently.
His name is Chu Tianyu, and he is the monitor of Class 3 of Inorganic Materials at Yenching University.
"Thank you, monitor, I'm fine, just a little cold." The girl smiled and shook her head.
"Then I'll pour hot water for you." As if worried about the girl's rejection, Chu Tianyu quickly added: "Don't refuse."
"Then, thank you monitor." The girl hesitated for a while, but did not refuse in the end.
"I said, don't call me the monitor, just call me by my name, or just call me Tianyu." Chu Tianyu said with a smile.
"Okay, monitor." The girl nodded.
"..." Chu Tianyu frowned slightly, then got up and walked towards the water dispenser at the end of the classroom.
"Wow! Tianyu is pouring water for Peng Linlin again, I'm so envious."
"I don't know how Peng Linlin's brain looks. How can such a handsome guy with a lot of money look down on him?"
"Who knows? Maybe they're arrogant."
"makes sense……"
Under the frantic gazes of the girls, Chu Tianyu came to Peng Linlin with a cup of boiling water.
"Be careful of the heat."
The smile is gentle, like a spring breeze.
"Wow."
A jealous voice sounded, and many girls had already fainted.
"Thank you." Peng Linlin smiled, took the water glass and put it on the table, but Peng Linlin didn't mean to drink water at all.
Seeing this scene, Chu Tianyu narrowed his eyes, a trace of displeasure flashed between his brows, and said with a soft laugh, "Linlin, in the early stage of a cold, you need to drink more hot water."
"I'm not thirsty now." Peng Linlin said expressionlessly.
"..." At this moment, Chu Tianyu's face was ashen.
"Do you have any questions about lithium battery technology?" At this moment, the lecturer suddenly asked.
"Yes!" Peng Linlin stood up: "How can the "isolation membrane" not be ruptured during the charging and discharging process of the battery?"
Lithium battery, one of the most widely used batteries today, is composed of positive and negative electrodes and an electrolyte.
During the charging and discharging process, a solid electrolyte interface film will be formed on the positive and negative electrodes to isolate the electrolyte and maintain the normal operation of the battery.
If this film ruptures, additional chemical reactions can occur that consume battery life.
"Unfortunately, the teacher can't answer you this question."
"Because as far as the technology is concerned, we can't guarantee that it won't break."
"It's just a matter of time when the electrode pierces the diaphragm," the teacher said helplessly.
Not just him, this is a common problem all over the world!
"Isn't it possible to do it once and for all?" Peng Linlin asked.
"Although there is no one-size-fits-all solution, we can extend the life of the battery through various materials!"
"It can't be done once and for all, but it can be done comfortably for 4.5 years."
"This is the meaning of our inorganic materials science." The teacher said with a smile.
"There is no way?" Peng Linlin asked reluctantly.
Method? Actually it is not.
The teacher pondered for a while and said slowly, "You should know about graphene, right?"
"Teacher, are you talking about materials that are more expensive than gold?" a student in the audience asked.
"That's right!"
"The world is currently conquering graphene battery technology."
"In time, if graphene batteries can come out smoothly, then once and for all will no longer be a dream."
