Chapter 307 Inorganic Materials Science
"Linlin, what's the matter, you don't feel well? Let me 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 Science at Yenching University.
"Thank you monitor, I'm fine, I just have a cold." The girl smiled and shook her head.
"Then I'll pour you a cup of hot water." As if worried about the girl's rejection, Chu Tianyu hurriedly added: "Don't refuse."
"Then, thank you monitor." The girl hesitated for a while, but finally did not refuse.
"I've said it all, don't call me 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 imperceptibly, 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 grows. Why can't she look down on such a handsome and expensive guy?"
"Who knows? Maybe he thinks he's high."
"makes sense……"
Under the enthusiastic eyes of all the girls, Chu Tianyu came to Peng Linlin with a glass of boiling water.
"Be careful of the heat."
The smile is gentle, like a spring breeze.
"Wow."
A voice of jealousy sounded, and many girls had already passed out.
"Thank you." Peng Linlin smiled, took the water glass and put it on the table, but Peng Linlin didn't intend to drink water at all.
Seeing this scene, Chu Tianyu narrowed his eyes, a trace of displeasure flashed across his brows, and said with a soft smile, "Linlin, at the beginning of a cold, 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 to ensure that the "isolation film" of the battery will not break during the charging and discharging process?"
Lithium battery, one of the most widely used batteries nowadays, is composed of positive and negative electrodes and electrolyte.
During the charge and discharge process, a solid electrolyte interface film is formed on the positive and negative electrodes to isolate the electrolyte and maintain the normal operation of the battery.
If this film breaks down, additional chemical reactions can occur that consume the life of the battery.
"Unfortunately, the teacher can't answer this question for you."
"Because as far as the current technical situation is concerned, we cannot guarantee that it will not break."
"It's only a matter of time before the electrodes break through 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-and-done solution, we can extend the battery life 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.
"Is there anything I can do?" Peng Linlin asked unwillingly.
Method?In fact, it is not without.
The teacher pondered for a while, then said slowly: "You should know about graphene, right?"
"Teacher, are you talking about the material that is more expensive than gold?" A student in the audience asked.
"That's right!"
"The whole world is currently attacking graphene battery technology."
"In time, if graphene batteries can come out smoothly, it will no longer be a dream once and for all."
