Chapter 130 Improving Lithium Batteries

The third update~

...

However, Qin Fang's speed of turning over the book was a bit scary, with a clattering sound, the students around couldn't help but look over, each with a look of curiosity and surprise on their faces.

"Fang Fang, are you alright..."

Tang Feifei also felt that something was wrong, she pushed Qin Fang lightly, and asked a little uneasy.

"It's okay, what's wrong?"

Qin Fang didn't feel anything, he didn't turn his head, he was still reading the book attentively, and then quickly turned the page.

"Are you sure you're all right?"

But the more this happened, the more abnormal it became. Tang Feifei pressed Qin Fang's hand to prevent him from continuing to turn down, and asked in a very uncertain tone.

"I'm really fine"

It was only at this time that Qin Fang noticed the eyes of the people around him, so he smiled bitterly and looked at the speed at which he turned the book. In such a short time, he had already gone down dozens of pages, and a textbook was only two or three hundred pages. , If he flips further, it is estimated that he has already done everything before this class is over.

"It's fine, don't scare me like that again next time."

Seeing that Qin Fang had finally stabilized, Tang Feifei breathed a sigh of relief, and had no mind to listen to the lecture, so she held Qin Fang's hand, for fear that he would do the same stupid thing again.

In this way, it is obviously impossible for Qin Fang to continue learning English, and his proficiency can only increase to this level, but at this time, the teacher on the stage has just started to talk about the first page, so that even the punctuation marks are deeply remembered. Qin Fang 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 easy to gossip with him. After thinking about it, he took out his mobile phone and planned to use her to pass the time.

"I, my phone is going to run out of power..."

Unfortunately, as soon as Qin Fang took out his mobile phone, he was depressed and found that the battery was low.

"Play with my phone or I'll give you the battery and you'll put it on..."

Tang Feifei is very understanding,

He took out his mobile phone from his small bag and handed it to Qin Fang.

Originally, Tang Feifei didn't care what kind of mobile phone she used, but since Qin Fang used Apple, she also specially changed it. It has the same model and configuration as Qin Fang, and even the settings of some ringtones are the same.

"Right, I remembered..."

Seeing Tang Feifei turn off the phone and take out the battery of the mobile phone, Qin Fang immediately remembered that he has been thinking about the improvement of lithium battery technology, but his repair skills are not high, and he has never started to do it. At this time, he is just free In a panic, Qin Fang decided to do it.

"Fang Fang, what are you doing?"

When Tang Feifei just took out the battery of the mobile phone and was about to hand it to Qin Fang, she was surprised to find that Qin Fang was dismantling his mobile phone.

"Remember what I told you last time? I'll study it first"

There are many people here, and Qin Fang can't be too straightforward, so he whispered something in Tang Feifei's ear.

"Oh, but you don't have the tools..."

They are here for class, and there is really nothing other than paper and pencil textbooks, "How did you take your phone apart..."

But before Tang Feifei finished speaking, she was surprised to find that Qin Fang had already disassembled his mobile phone, and even prepared for further disassembly. A plan to never give up.

"Hey, who said there are no tools, isn't it?"

Qin Fang smiled and raised the fingernail clippers, ear scoops, keys, buckles and other things on his hand. He used these things to disassemble a still brand new mobile phone into a pile of parts.

"That's fine too..."

Tang Feifei was surprised. She had never seen such a skill, dismantling a precisely assembled mobile phone with these completely irregular "tools".

Soon the phone was disassembled. As for the circuit board, Qin Fang did not move it. These things are considered relatively precise. If he fiddled with these thicker things, it would easily cause some unnecessary damage. Second, there are some deviations from his research direction. He wants to study the battery, and only needs to understand the structure of the mobile phone, the power supply route, and so on.

"Fifi, did you bring something smaller? For example, ear studs, hairpins, etc..."

After disassembling the mobile phone, the next step is to disassemble the battery. However, this thing is a little more complicated to disassemble than the mobile phone, and these "tools" are not suitable for Qin Fang, so Qin Fang has to turn to Tang Feifei for help.

"Yes, yes..."

Tang Feifei nodded immediately, then opened her small bag and rummaged in it, because she was going to wake Qin Fang up in the morning, she went out very early, and she didn't have any earrings. And she has always had shawl hair, either draped like this or tied into a small braid. She rarely uses hairpins, and naturally she doesn't.

In the end, he took out a few pins and asked cautiously, as if he was afraid of Qin Fang's anger, "Is this okay?"

"That's fine..."

Qin Fang originally wanted some needle-like things, but he also knew that most girls today do not know how to needle and thread, and these things are definitely not available, so he will settle for the next best thing. At least it has a pointed tip.

With better "tools", Qin Fang's efficiency is much higher. He quickly disassembled his mobile phone battery into a bunch of parts, and disassembled the battery that Tang Feifei gave him along with it. .

Lithium electronic batteries are actually a type of batteries that use lithium metal or lithium alloy as the negative electrode material and use a non-aqueous electrolyte solution. At present, although there are many kinds of negative electrode materials for lithium batteries in name, they can basically have commercial value and are also the most widely used. It is the carbon anode material.

The same is true for the lithium batteries used in the two mobile phones in Qin Fang's hands.

Of course, many battery companies are currently researching and developing lithium batteries with nanomaterials as anode materials, but most of them are still in the laboratory stage and have not yet formed much commercial value. A long way to go.

Qin Fang obviously does not have such scientific research conditions. At the same time, his proficiency limit also limits his research level. Even if he knows how to improve, he still cannot meet the conditions.

However, let alone, the power of repair skills is also reflected at such a moment. Even in the face of such a relatively simple lithium battery facility, under such simple conditions, there is still an improvement plan. of.

The name of the solution given by the repair skills is called positive and negative bridge interconversion. Qin Fang can't understand the principle of distance. It is even unknown that this technology has not been discovered by humans yet. The only thing he can do The key is to operate and execute in accordance with the improvement plan given by the repair skills.

This improvement plan is relatively primitive, and the operation method is also very simple. Qin Fang simply set up a few incomprehensible connection circuits in it according to the prompts, and then reassembled the battery and mobile phone. stand up.

"Is that all right?"

Tang Feifei has been watching, not daring to say a word, for fear that she will interrupt Qin Fang's thoughts, but when Qin Fang reassembled the phone and put the battery back, she couldn't help asking.

From her point of view, in addition to dismantling the phone and battery, Qin Fang simply used the tip of the pin she gave to poke the battery a few times at random. Will he get him? I don't know if it's bad for the time being, but let her believe that this will improve the lithium battery, and she won't believe it if she is killed.

It's not that she doesn't have confidence in Qin Fang. It's really incredible. If it's really that simple, why would those world-class battery companies spend so much to develop more advanced technologies?

"Haha, I'll know right away if it's okay or not"

After Qin Fang finished, he turned on the machine immediately. In fact, he was very suspicious of Tang Feifei's question.

It is not the reliability of the repair skills, but the suspicion that the technique is not proficient enough to meet the requirements, which leads to the failure of this improvement plan.

Of course, at the same time, he also has a certain degree of confidence. The main reason is that this plan is really very simple, and it is so simple that it is completed without any changes.

"Hey, it's turned on, let me see... Is it full?"

While the two were talking, the phone was turned on again. Tang Feifei immediately took the phone from Qin Fang's hand nervously, and was surprised to find that the battery of the phone was full again.

"Fang Fang, did you install the wrong battery?"

Before Qin Fang's mobile phone battery display was indeed close to empty, while her own was full, but at this time the battery level displayed on the mobile phone was full, and after waiting for a few minutes, Tang Feifei also carried out some The operation of the system, but the battery is still full, suddenly asked with some doubts.

Qin Fang couldn't help rolling his eyes, could he possibly make such a mistake?

He carefully distinguished the two batteries and the corresponding parts to prevent them from being connected incorrectly. As for why the battery became full, Qin Fang was also quite puzzled.

"Don't be suspicious, I've heard people say that in fact, when these lithium batteries are shown to be empty, they generally retain at least one-third of the power, which means that the actual power used may be more than two-thirds. In addition to the general display of full battery, most of them have been used a lot, and it seems normal now that it seems to be full..."

At this moment, Xiao Nan, who had been "listening to the lectures earnestly", suddenly turned his head and said, "I said the fourth, who did you learn this trick from? It's so powerful?"
