Can we get a battery with a larger capacity under the same volume?

Qin Lu never doubted his brain.

However, his mind was empty now, and Qin Lu didn't know where to start. The first thing he thought of was graphene batteries.

Rice and Warwick are recently promoting that they will soon develop graphene batteries.

Qin Lu was also somewhat interested in him.

However, after looking for some information online, he found that graphene batteries did not increase the capacity of the battery, but only the charging speed and service life.

Moreover, under the same volume, the capacity of the battery will decrease after using graphene.

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

Of course, if you develop better charging and discharging materials during your research, it would be a different matter.

Qin Lu, who had no idea for the time being, set his sight on the blackboard.

Although listening to the class is boring, it must be very interesting if you can find out the mistakes in the teacher's lecture.

However, after listening for a while, Qin Lu found that his teacher's professional ability is still very strong. Although he was reading the subject with PPT, the knowledge points he taught were very solid and met the requirements of the undergraduate stage.

Of course, for Qin Lu, he has understood the whole book thoroughly, that is, he can just listen to his ideas to confirm it.

Soon, the bell rang after class.

There was no class in the third and fourth quarter of the morning, but because the teacher adjusted the class that was originally the evening to the morning, I still had to go to this class.

Of course, this is also a good phenomenon. At least you don’t have to run from the northeast corner of the school to the southwest corner to attend classes at night.

Chemistry English is a test course, which is the one that opens the final exam. Naturally, there is nothing good to take in this course, and many comrades choose to escape.

But recently, because this teacher wants to give her usual grades, she will ask questions from time to time in class. Those who usually skip classes also take books and go to class with their books.

"English, it's been a long time since I've been using it!" In the original trajectory, Qin Lu is an online writer. After graduation, he continued to write novels. Not to mention, he is doing well.

So the English thing has been given to the English teacher a long time ago.

"By the way, I've been back from rebirth for a long time, it hasn't been updated..." Qin Lu scratched his head. After he came back from rebirth, he was busy thinking about practicing. After his mind was improved, he was thinking about how to do the Iron Armor, and he forgot his financial resources.

He took out his cell phone and logged into the writer's backstage to see that Qin Lu found that he still had dozens of chapters of manuscripts, and immediately breathed a sigh of relief.

It seems that I can still earn some money in the short term.

However, since this class is English, it will take a class to complete the English.

If you want to talk about the super brain that you can never forget, what is the fastest thing you can learn? There is no doubt that it is linguistics.

Moreover, if you learn English well, whether it is computers or various foreign literature, you will be able to learn it well in the future.

Thinking of this, Qin Lu stood up and walked towards the classmate who was the best English student in the class.

"Zhang Yu, do you have vocabulary books or grammar books? Please lend them to me!" Qin Lu knocked on the table and said to Zhang Yu who was looking at IELTS.

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

Zhang Yu and Qin Lu are both students in the class who are not majoring in chemistry. In addition, the two of them work together to attend partying, so their relationship is pretty good.

"I just know that the people here are all difficult, so I want them!" Qin Lu smiled, nodded, and replied.

"Okay, give it!" Zhang Yu thought to himself that it would be strange if I believe you. He shook his head speechlessly, took out the book from his bag and handed it to Qin Lu.

"Thank you, I'll go back and invite you to have a drink!" Qin Luyang Yangshu, then turned around and walked towards his seat!

"Hey, Brother Lu, what's wrong with you? Look at IELTS? Are you sure you are not trying to attract people's attention to Zhang Yu?" Wang Yazhe looked at Qin Lu holding two books, his mouth twitched and said in a low voice.

"Although I have no partner, my vision is not that bad!" Qin Lu rolled his eyes and whispered.

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

Of course, the most important thing is that Qin Lu doesn't like this type of person.

"Tsk, who knows if you are too hungry or thirsty!" Wang Yazhe knew what Qin Lu meant, rolled his eyes, turned his head and continued to play with his phone.

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

Sure enough, in addition to the recognition of letters and Chinese characters, there are only a few explanations of vocabulary, namely a, an, and the other...

In more than 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 it all, because Qin Lu's previous English skills were really poor, even if he wrote it down, he was almost used.

However, Qin Lu had his English skills in his mind at least, in order to take the CET-4 English test before he was reborn, he had read the CET-4 vocabulary books, the CET-4 questions he had done, and the US blockbusters he had watched...

It took me half an hour to make my mind go crazy. Qin Lu's English skills did not speak loudly, communicated with foreigners, and had no problem reading general foreign language materials.

"english?so easy!" Qin Lu smiled twitchingly, then put the book together, took out his mobile phone, and found some papers related to the battery to read.

Of course, if you have a preliminary understanding of this knowledge, and then give your mind some impression, you need to learn systematically about batteries.

Qin Lu estimated that he had to find his top student sister, Qin Xue, who was studying for a master's degree at Xijing Jiaotong University.

"How can I make my first pot of gold? Even if I have developed the battery, I still need to open a company and build a factory. All of these require money!" After looking at it for a while, Qin Lu restrained a little and did not play with his mobile phone anymore.

Well, it was just because the professor started wandering in 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 Qin Lu's mind did not come up with the reason.

Dingling!

A ringtone rang and get out of class was over.

College classes are usually composed of two small classes into one large class, with ten minutes of rest in between.

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

Wang Yazhe always buys a few lottery tickets a week, and always fantasizes about buying his beloved Land Rover Range Rover after winning the lottery. However, this guy took the second exam three times in the subject and has not passed yet!

Qin Lu, who had no choice but to think about a lesson, was inspired by Wang Yazhe's words!

Buy a lottery ticket. If you don’t buy a lottery ticket after returning from rebirth, you’re sorry to readers, right?

If you want to say something else, Qin Lu may not have thought of it. If he doesn't watch the football, he can't bet on the football.

Going to gambling? Hey! It doesn’t conform to the core socialist values!

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

And you know what you have seen!

Qin Lu's heart was filled with disgust on his face, looking at Wang Yazhe and said, "Buy lottery? Lao Wang, don't think about it in your life, hurry up and go back and take a shower and go to bed!"

"Tsk, if you don't go, I'll go, I won't believe it. I'll be lucky all the time. At least I won five dollars in the last issue!" Wang Yazhe looked at Qin Lu, turned his head, took out his mobile phone to check the winning numbers in the previous issue, and went to calculate it on his own.

Qin Lu skipped class.

This teacher asked questions one by one by one by one, and Qin Lu had already achieved his usual grades, so he ran away with confidence.

Moreover, the memories of my previous life are there, and I won’t ask boys in this class at all.

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

As for the goal...
Chapter completed!
