Third Update ~
… …
However, the speed at which Qin Fang was flipping through the book was a bit scary. The students around couldn't help but look over. Their faces were quite curious and surprised.
"Fang Fang, are you okay …"
Tang Feifei also felt that something was wrong. She gently pushed Qin Fang and asked with some concern.
"I'm fine!
What's wrong? "
Qin Fang didn't feel anything. He didn't turn his head. He was still focused on reading the book, and then he quickly turned to the next page.
"Are you sure you're okay?"
But the more it was like this, the more abnormal it was. Tang Feifei held Qin Fang's hand and stopped him from continuing to turn the page. She asked in a very uncertain tone.
"I'm really fine!"
Qin Fang noticed the eyes of the people around him at this time. He immediately smiled bitterly and looked at the speed at which he was turning the book. In such a short time, he had already turned over dozens of pages. A textbook was only two or three hundred pages. If he continued to turn the book, he would probably have finished it all before the end of the class.
"It's good that you're okay. Don't scare me like this next time!"
Seeing that Qin Fang finally calmed down, Tang Feifei breathed a sigh of relief. She was not in the mood to listen to the class. She just held Qin Fang's hand, afraid that he would do the same stupid thing just now.
In this way, Qin Fang obviously couldn't continue to learn English. His proficiency could only increase to this level. But at this time, the teacher on the stage had just started to talk about the first page. Qin Fang, who even remembered punctuation deeply, suddenly felt quite bored.
Looking at Xiao Nan next to him, he didn't sleep. He seemed to be listening to the class very seriously. Naturally, it was not good to chat with him. He thought about it and took out his mobile phone, ready to use it to pass the time.
"D * mn, the phone is going to run out of battery …"
Unfortunately, Qin Fang just took out his mobile phone, and he was depressed to find that the battery was running out. If he really played, it would probably die in a few minutes.
"Use my mobile phone to play!
Or I can give you the battery and you can replace it … "
Tang Feifei was very considerate. She took out her mobile phone from her small bag and handed it to Qin Fang.
Originally, Tang Feifei didn't care what kind of mobile phone she used. However, ever since Qin Fang started using an Apple phone, she also changed her phone. It was the same model, configuration, and even some of the ringtone settings were the same as Qin Fang's.
"Right, I remember now …"
When he saw Tang Feifei turn off her phone and remove the battery, Qin Fang immediately remembered. He had been thinking about how to improve the lithium battery. However, his repair skill was not very proficient, so he did not do it. Now that he had nothing to do, Qin Fang decided to do it.
"Fang Fang, what are you doing?"
Tang Feifei had just taken out the phone battery and was about to hand it to Qin Fang when she was surprised to find that Qin Fang was disassembling his phone.
"Do you still remember what I told you last time?
Let me do some research first! "
There were many people here, so Qin Fang couldn't be too direct. He whispered in Tang Feifei's ear.
"Oh!
But you don't have any tools … "
They were here for class. Other than a pen and paper and textbooks, they didn't have anything else. "How did you disassemble the phone …"
However, before Tang Feifei could finish her sentence, she was surprised to find that Qin Fang had already disassembled his phone. He was even preparing to disassemble it further. It seemed like he was not going to stop until he completely restored the phone to its original parts.
"Hehe, who said that I don't have tools? Isn't this the case?"
Qin Fang smiled and waved the nail clippers, ear picks, keys, clasps, and other things in his hand. He used these things to disassemble a brand new phone into a pile of parts.
"That works …"
Tang Feifei was surprised. She had never seen such an ability. He used these completely irregular "tools" to disassemble a finely assembled phone.
Soon, the phone was disassembled. As for the circuit board and the like, Qin Fang didn't touch it. First of all, these things were relatively sophisticated. If he fiddled with these relatively rough things, it would easily cause some unnecessary damage. Second of all, it would deviate from the direction of his research. He wanted to study the battery. He only needed to understand the structure of the phone, the power supply route, and so on.
"Feifei, did you bring some smaller things?
For example, earrings, hair clips, and so on … "
After disassembling the phone, the next step was to disassemble the battery. However, this thing was a little more complicated than the phone. Qin Fang's "tools" were not suitable. Qin Fang had to ask Tang Feifei for help.
"Yes, yes …"
Tang Feifei nodded immediately, then opened her small carry-on bag and rummaged in it. Because she had to wake Qin Fang up in the morning, she went out very early. She didn't bring earrings and the like. She always had shoulder-length hair. It was either draped like this or tied into a small braid. She rarely used a hair clip, so naturally, she didn't have one.
Finally, she took out a few pins and asked carefully. She looked like she was afraid that Qin Fang would be angry. "Is this okay?"
"Yes!
This is just right … "
Qin Fang originally wanted some needle-like things, but he also knew that most girls nowadays didn't know how to needle and thread. These things were definitely not available, so he settled for the next best thing. He didn't expect there to be such things. Although it was just a pin, at least it had a sharp point.
With better "tools", Qin Fang's efficiency was much higher. He quickly disassembled his phone battery into a pile of parts. He also disassembled the battery that Tang Feifei gave him.
Lithium-electron batteries were actually a type of battery that used lithium metal or lithium alloy as the anode material and a non-aqueous electrolyte solution. At present, although there were many kinds of anode materials for lithium batteries, they basically had commercial value. At the same time, the most widely used anode materials were carbon anode materials.
The lithium batteries used in the two phones in Qin Fang's hands were the same.
Of course, at present, many battery companies were researching and developing nanomaterials as anode materials for lithium batteries, but most of them were still in the laboratory stage. For the time being, they didn't have much commercial value. As for popularizing the market, it would obviously take a long time.
Qin Fang obviously didn't have such scientific research conditions. At the same time, his proficiency limit also limited his research. Even if he knew how to improve it, he still couldn't meet the requirements.
However, the power of the repair skill was reflected at this moment. Even in the face of such a relatively simple lithium battery facility, under such simple conditions, there was still an improvement plan.
The name of the solution given by the repair skill was called positive and negative bridging. Qin Fang didn't understand the principle of distance. It was even possible that this technology hadn't been discovered by humans yet. The only thing he could do was to follow the improvement plan given by the repair skill.
This kind of improvement plan was relatively primitive, and the operation method was also very simple. Qin Fang just followed the instructions and simply set up a few connections that people couldn't understand. Then, he reassembled the battery and phone.
"That's it?"
Tang Feifei had been watching from the side. She didn't dare to say a word. She was afraid that she would interrupt Qin Fang's train of thought. However, after Qin Fang reassembled the phone and put the battery back in, she couldn't help but ask.
From her point of view, besides disassembling the phone and battery, Qin Fang simply used the tip of the pin she gave him to poke the battery a few times. She didn't know if he would damage the battery, but she didn't believe that this could improve the lithium battery.
It wasn't that she didn't have confidence in Qin Fang, but it was too unbelievable. If it was really so simple, then why would those world-class battery companies spend so much money to develop more advanced technology?
"Hehe, we'll know soon!"
After Qin Fang finished, he immediately turned on the phone. In fact, he was also very skeptical about Tang Feifei's question.
It wasn't that he doubted the reliability of the repair skill, but that he wasn't skilled enough and couldn't meet the requirements, which led to the failure of the improvement plan.
Of course, at the same time, he also had a certain degree of confidence. The main reason was that this plan was indeed very simple. It was so simple that it was completed without any changes.
"Oh, it's turned on, let me see … full battery?"
While the two were talking, the phone was turned on again. Tang Feifei immediately took the phone from Qin Fang's hands a little nervously. She was surprised to find that the battery was full again.
"Fang Fang, did you install the wrong battery?"
Previously, Qin Fang's phone battery was almost empty, but her phone was full. However, at this time, the battery was still full. Tang Feifei deliberately waited for a few minutes. She also did some system operations, but the battery was still full. She immediately asked in confusion.
Qin Fang couldn't help but roll his eyes. Would he make such a mistake?
He had carefully separated the two batteries and the corresponding components to prevent them from being connected by mistake. As for why the battery was full, Qin Fang was also puzzled.
"Don't be suspicious, I heard people say that when these lithium batteries are empty, at least one-third of the battery will be left. That is to say, the battery that is really used may be more than two-thirds. In addition, the battery that is usually full is mostly used. It's normal for it to look full now …"
At this moment, Xiao Nan, who had been "listening carefully", suddenly turned his head and said, "The Fourth, where did you learn this trick from? It's so good!"
