Chapter 307： Inorganic Materials (2/2)
”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” will not break during the battery charge and discharge process?”
Lithium batteries, one of the most widely used batteries today, are 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 ruptures, additional chemical reactions will occur, consuming the life of the battery.
”Unfortunately, the teacher can't answer you this question.”
”Because from the current technological situation, we cannot guarantee that it will not break.”
”The electrode breaks through the diaphragm, it's just a matter of time.” The teacher said helplessly.
Not just him, this is a common problem all over the world!
”Is it impossible to do it once and for all?” Peng Linlin asked.
”Although there is no solution once and for all, we can extend the life of the battery through various materials!”
”You can't do it once and for all, but you can do it for 4.5 years.”
”This is the meaning of our inorganic materials science.” The teacher said with a smile.
”Is there no way?” Peng Linlin asked without giving up.
Method? In fact, it is not without.
The teacher pondered for a while, then slowly said: ”You should know graphene, right?”
”Teacher, are you talking about materials that are more expensive than gold?” asked a student in the audience.
”Yes!”
”The world is currently conquering graphene battery technology.”
”In time, if graphene batteries can come out smoothly, it will no longer be a dream once and for all.”
