C307 Inorganic Material Science

"Linlin, what's wrong? Are you not feeling well? I'll ask the teacher for a leave of absence for you. " A handsome boy beside him gently asked.

His name was Chu Tianyu, and he was the class monitor of Yanjing University's third class in inorganic materials.

"Thank you class monitor, I'm fine, I just had a cold." The girl smiled and shook her head.

"Then I'll get you hot water." Seemingly worried that the girl would refuse, Chu Tianyu added, "Don't refuse."

"Then, thank you class monitor." The girl hesitated for a moment, but in the end, she did not refuse.

"I already said, don't call me class monitor. Just call me by my name or Tianyu." Chu Tianyu said with a smile.

"Understood, class monitor." The girl nodded.

"…" Chu Tianyu's eyebrows creased imperceptibly as he stood up and walked towards the water dispenser at the end of the classroom.

"Wah!" "Tianyu is pouring water for Peng Linlin again. I'm so envious of her."

"I wonder what's going on with Peng Linlin's brain. How come she doesn't like such a handsome guy who's worth a lot?"

"Who knows? Maybe he thinks he's too arrogant. "

"You're right …"

Under the fervent gazes of the girls, Chu Tianyu brought a cup of boiling water in front of Peng Linlin.

"Be careful."

Her smile was gentle, like the spring breeze.

"Wow."

A envious voice echoed, and many female students had already fainted.

"Thank you." Peng Linlin smiled as she took the cup and placed it on the table. However, Peng Linlin had no intention of drinking the water.

Seeing this, Chu Tianyu's eyes narrowed and a hint of displeasure flashed across his face. He laughed softly, "Linlin, you should drink more hot water at the beginning of your cold."

"I'm not thirsty right now." Peng Linlin said with an expressionless face.

"…" At this moment, Chu Tianyu's face was ashen.

"Do you have any questions on lithium battery technology, students?" At this moment, the lecturer suddenly asked a question.

"Yes!" Peng Linlin stood up. "How do you ensure that the" isolation membrane "doesn't break during the charging and discharging process?"

Lithium battery, one of the most widely used batteries today, consists of positive and negative poles and electrolyte.

During the charging and discharging process, a solid electrolyte interface film will be formed on the positive and negative electrode to isolate the electrolyte and keep the battery operating normally.

If the membrane ruptures, there will be an additional chemical reaction that will consume the battery life.

"Unfortunately, teacher is unable to answer this question."

"Because in the current technical context, we cannot guarantee that it will not break."

"It's only a matter of time before the electrode breaks the membrane." The teacher said helplessly.

Not just him, this was a common problem for the entire world!

"Is there no way to solve it once and for all?" Peng Linlin asked.1

"Although there's no way to do it once and for all, 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 for 4.5 years."

"This is the meaning of the existence of our inorganic materials." The teacher said with a laugh.

"There's no way at all?" Peng Linlin asked, unwilling to give up.

Method? Actually, it wasn't like there weren't any.

The teacher pondered for a moment before slowly saying, "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!"

"Currently, the entire world is taking down Graphene Cell technology."

"With enough time, if the Graphene Cell is able to come out successfully, once and for all, it would no longer be a dream."
