Is it possible to make a battery with a larger capacity for the same volume?

Qin Lu didn't doubt his brain.

However, now his mind is empty, Qin Lu doesn't know where to start, the first thing he thinks of is graphene batteries.

Rice and Huawei have recently advertised that they are about to develop graphene batteries.

Qin Lu was also a little interested in it.

However, when he looked for some information on the Internet, he found that the original graphene battery did not improve the capacity of the battery, but only the charging speed and service life.

In addition, the capacity of the battery decreases even after graphene is used in the same volume.

However, graphene is not undesirable, because the advantages of graphene in charging speed are worth referencing.

Of course, if you develop better charging and discharging materials in the process of research, it will be a different matter.

Qin Lu, who had no clue for the time being, put his eyes on the blackboard.

It's not fun to listen to the class, but it will be interesting if you can find out the mistakes of the teacher's lecture.

However, after listening for a while, Qin Lu found that his professional ability as a teacher was still very strong, although he was holding a PPT to read from the book, but the knowledge points taught were very solid, which met the requirements of the undergraduate level.

Of course, for Qin Lu, he has eaten the whole book thoroughly, that is, he listens to the ideas to confirm it and so on.

Soon, the bell rang for the end of class.

Originally, there was no class in the third or fourth period in the morning, but because the teacher moved the class that was supposed to be in the evening to the morning, this class still had to be held.

Of course, this is also a good sign, at least in the evening, you don't have to run from the northeast corner to the southwest corner of the school to attend classes.

English for chemistry majors, an examination course, that is, the kind of final exam open-book, this kind of class is naturally not good, and many comrades choose to escape.

But recently, the teacher has to give the usual grades, so he will ask questions from time to time in class, and those who usually skip class also take books one by one and go to class.

"English, it's been a long time!" In the original trajectory, Qin Lu was an online writer, and after graduation, he continued to write novels, not to mention, he mixed well.

So the English thing has long been returned to the English teacher.

"Anyway, I haven't updated it for a long time since I came back from rebirth......," Qin Lu scratched his head, after he came back from rebirth, he had been busy thinking about cultivation, and after his brain was better, he was thinking about how to get the steel armor, and he forgot about his financial resources.

Taking out his mobile phone and logging in to the writer's backstage, Qin Lu found that he still had dozens of chapters in his manuscript, and he immediately breathed a sigh of relief.

It seems that he can still have a little income in the short term.

However, since this lesson is in English, it will take one lesson to get the English done.

If you want to say that the super brain cooperates with the eye, what is the fastest thing to learn, there is no doubt that it is linguistics.

Moreover, if you learn English well, whether it is a computer or a variety of foreign literature, you will be able to grasp it in the future.

Thinking of this, Qin Lu got up and walked towards the best English classmate in the class.

"Zhang Yu, do you have a vocabulary book and a grammar book, borrow it from me!" Qin Lu knocked on the table and said to Zhang Yu, who was watching IELTS.

"I'm all IELTS, do you want to see it?" Zhang Yu looked up at Qin Lu and asked.

Zhang Yu and Qin Lu are not like chemistry majors in the class, and the two of them usually cooperate together to attend parties and the like, so the relationship is not bad.

"I just know that you have a high level of difficulty here, so I want it!" Qin Lu smiled, nodded, and replied.

"Alright then, give it!" Zhang Yu said in his heart, I believe that you are strange, shook his head speechlessly, took out the book from his bag, and handed it to Qin Lu.

"Thanks, I'll get you a drink!" Qin Lu raised his book, then turned around and walked towards his seat!

"Hey, Brother Lu, what's wrong with you, do you look at IELTS? Are you sure you're not trying to attract people's attention just to soak Zhang Yu? Wang Yazhe looked at Qin Lu, who was holding two books, the corners of his mouth twitched, and he whispered.

"Although Lao Tzu has no object, his vision is not so bad!" Qin Lu rolled his eyes and whispered.

Zhang Yu is a typical Northwest girl, so her skin is relatively dark, so she usually wears very thick makeup.

Of course, the main thing is that Qin Lu doesn't like this type.

"Cut, who knows if you're hungry and thirsty!" Wang Yazhe knew what Qin Lu meant, rolled his eyes, turned his head and continued to play with his mobile phone.

Qin Lu looked at him, quickly opened the book, and began to browse.

Sure enough, in addition to the understanding of letters and Chinese characters, there are also a few sporadic explanations of vocabulary recognition, that is, a, an, and the......

In ten minutes, Qin Lu finished reading both books, and every character in the book was reflected in Qin Lu's mind.

Of course, although I ate all the dates after swallowing them, because Qin Lu's previous English skills were too poor, even if I wrote them down, I was almost useless to use them.

However, Qin Lu still has the original English skills in his mind, plus the level 4 vocabulary books he has read, the level 4 questions he has done, and the blockbusters he has watched in order to take the English level 4 test before he was reborn......

It took half an hour to think in his head, Qin Lu's English skills, not to speak big, to communicate with foreigners, and to be familiar with general foreign language materials without the slightest problem.

“English?so easy!” Qin Lu smiled draggedly, then closed the book, took out his mobile phone, and found some battery-related papers to read.

Of course, a preliminary understanding of these knowledge, and then make some impressions in the mind, about the battery, but also to learn systematically.

Qin Lu estimated that he still had to go to find his sister who was a scholar, Qin Xue, who was in her first year of graduate school at Xijing Jiaotong University.

"How to get the first pot of gold, even if the battery is researched, you need to open a company, build a factory, all of this, you need money!" After watching it for a while, Qin Lu restrained himself a little and didn't play with his mobile phone anymore.

Uh, just because the professor started wandering down the aisle.

Qin Lu, who was idle, naturally took out his small notebook and began to plan the next arrangements.

After thinking about a lesson, even if it was Qin Lu's brain, he didn't come up with a reason.

Jingle bells!

A bell rang, and class ended.

Classes at university are generally two small classes combined into one large class, with a ten-minute break in between.

"Brother Lu, after class at noon, buy a lottery ticket!" Wang Yazhe suddenly grabbed Qin Lu's arm and said excitedly.

Wang Yazhe, this guy, always goes to buy a few lottery tickets a week, and always fantasizes about buying his beloved Range Rover after winning the lottery, however, this guy has taken the second test three times, and he hasn't passed it yet!

Qin Lu, who had thought about a lesson and had no method, was inspired by Wang Yazhe's words!

Buy a lottery ticket.,If you don't buy a lottery ticket when you come back from rebirth.,That's not sorry for the readers, isn't it?

If he wants to say something else, Qin Lu may not be able to think of it, he doesn't watch the ball, and there is no way to gamble.

Going gambling? Hey! It doesn't conform to the core values of socialism!

But because Wang Yazhe has been buying lottery tickets, although Qin Lu has not seen the winning numbers in every issue, there are also a few issues where the winning numbers have been seen.

And you've seen it, you know!

Qin Lu's heart fluctuated one after another, but his face was disgusted, he looked at Wang Yazhe and said, "Buy a lottery ticket?" Lao Wang, don't think about it in your life, hurry up and go back to wash and sleep! ”

"Cut, if you don't go, I'll go, I don't believe it, my luck can be bad all the time, but I won five yuan in the last issue!" Wang Yazhe looked at Qin Lu, turned his head, took out his mobile phone to check the winning numbers of the previous period, and calculated by himself.

As for Qin Lu, he skipped class.

This teacher, the questions are all asked one by one next to the student number, Qin Lu has already had his usual grades, so he escaped with confidence.

Moreover, the memories of the previous life are there, and in this class, there will be no questions about the boys at all.

So, Qin Lu returned the book, and then slipped away!

As for the goal......
