Chapter 130 Improving Lithium Batteries

However, the speed of Qin Fang’s book flipping is a bit scary, and the students around me couldn’t help but look at it. Each face is quite curious and surprised.

"Fang Fang, you are fine..."

Tang Feifei also felt that something was wrong, and gently pushed the Qin side, some did not ask very assured.

"Nothing! What happened?"

Qin Fang did not feel anything, and the head did not turn around, still looking at the book intently, and then quickly flipped to the next page.

"Are you sure nothing?"

The more it is, the more unnatural it is. Tang Feifei held down Qin’s hand and prevented him from continuing to turn it down, asking in a very uncertain tone.

"I am really fine!"

At this time, Qin Fang noticed the eyes of the people around him. He immediately smiled a bit and looked at the speed of his own book. It took a few dozen pages for a while, and a textbook was only two or three hundred pages. If you turn it down again, it is estimated that this class is not over, and he has already done it all.

"It’s okay, I won’t be scared again next time!”

When I saw that Qin Fang had finally stabilized, Tang Feifei took a sigh of relief and did not have the heart to listen to the class. So he took Qin’s hand and feared that he would follow the stupid things just now.

In this way, it is obviously impossible for Qin Fang to continue to learn English. The proficiency can only grow to this level. At this time, the teacher on the stage just started to talk about the first page, so that even the punctuation marks are memorable. Qin Fang suddenly felt quite boring.

Look at Xiao Nan next to him, actually did not sleep, it seems very serious in the way of listening to the class, naturally it is not easy to talk with him, think about it and took out the phone, ready to use her to pass the time.

"I rely on, the phone has no electricity..."

Unfortunately, Qin Fang’s cell phone just came out, and he was depressed and found that the power was insufficient. If it was to be played, it would be estimated that it would take a few minutes to get fart.

"Play with my phone! Or I will give you the battery, you put it on..."

Tang Feifei was very understanding, and took his mobile phone from his small bag and handed it to Qin.

Originally, Tang Feifei did not care what kind of mobile phone to use. Since Qin Fang used Apple, she also changed one specially. The same model and configuration as Qin Fang, even the settings of some ringtones are the same.

"Right, I remembered..."

Seeing that Tang Feifei shut down the mobile phone battery, Qin Fang immediately remembered that he had been pondering the improvement of lithium battery technology, but his repair skills were not proficient, and he never started to work. Panic, Qin Fang intends to start.

"Fang Fang, what are you doing?"

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

“Remember what happened to you last time? Let me study it first!”

There are a lot of people here, and Qin Fang is not too straightforward to say, and he whispered in the ear of Tang Feifei.

"Oh! But you don't have tools..."

They came to class. There is nothing else besides the paper and pencil textbook. "How do you take the phone apart?"

However, Tang Feifei did not finish this sentence, and he was surprised to find that Qin Fang had already dismantled his mobile phone, and even prepared for further dismantling. It seems that he did not restore all the mobile phones to parts. I don’t want to give up.

"Hey, who said there is no tool, isn't this?"

Qin Fang smiled and raised the nail clippers, ear spoons, keys, buckles and the like on his hands. He used these things to split a still new phone into a pile of parts.

"This is also OK..."

Tang Feifei was surprised. She had never seen such a skill. She used these completely irregular "tools" to disassemble a well-assembled mobile phone.

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

"Fifi, do you have some smaller things? Such as earrings, hairpins, etc..."

After dismantling the mobile phone, the battery will be dismantled. However, it is more complicated to disassemble than the mobile phone. The "tools" of Qin Fang are not suitable. Qin Fang had to resort to Tang Feifei.

"Yes, there are..."

Tang Feifei immediately nodded, then opened her small carry-on bag and rummaged inside, because in the morning she would call Qin Fang to get up, she went out very early, she didn’t have earrings or the like. Belt, and she has always been a shawl hair, or it is so draped, or is tied into a small pimple, rarely used card, naturally not.

Finally, I took out a few pins and asked carefully, and I was very worried about Qin’s anger. "Is this the line?"

"Yes! This is just right..."

Qin Fang originally wanted some needles, but he also knows that most girls nowadays don’t have needlework. These things are definitely not there, so they will retreat to the next level. I didn’t expect it to be true, even though it’s just a pin. At least there is a pointed tip.

With a better "tool", Qin Fang's efficiency was much higher. He quickly dismantled his mobile phone battery into a pile of parts, and along with the battery that Tang Feifei gave him. .

A lithium-ion battery is actually a kind of battery that uses a lithium metal or a lithium alloy as a negative electrode material and uses a non-aqueous electrolyte solution. However, the lithium battery negative electrode material, although nominally many kinds, can basically have commercial value and is also the most widely used. It is the carbon anode material.

The lithium batteries used in these two mobile phones in Qin Fang’s hands are the same.

Of course, many battery companies are currently researching and developing lithium batteries as negative electrode materials for nanomaterials, but most of them are still in the laboratory stage, and they have not yet formed much commercial value. As for the popularization of the market, it is obviously necessary to go. It takes a long way to go.

Qin Fang obviously does not have such scientific research conditions, and his proficiency limits also limit his research level, even if he knows how to improve it can still not meet the conditions.

However, it is true that the power of repair skills is reflected in such a moment, even in the face of such a relatively simple lithium battery facility, under such simple conditions, there are still improved solutions. of.

The name of the scheme given by the repair skill is called the positive and negative bridges. What is the principle of the distance? The Qin side can't understand it. Even if this technology has not been discovered by humans, it is unknown. He can only do it. The operation is performed according to the improvement scheme given by the repair skill.

This kind of improvement scheme is relatively primitive, and the operation method is also very simple. Qin Fang simply set up several connection loops that people can't understand according to the prompts, and then re-assemble the battery and mobile phone again. stand up.

"Is this all right?"

Tang Feifei always looked around and didn't dare to scream, for fear that he interrupted Qin's ideas, but when Qin Fang reassembled the phone and put the battery back, he couldn't help but ask.

From her point of view, in addition to dismantling the mobile phone and the battery, Qin Fang simply used the tip of the pin that she gave the pin to poke a few times in the battery, will it be made by him? Bad for the time being, I don’t know, but let her believe that this will improve the lithium battery, and will not believe it.

It is not that she has no confidence in Qin Fang. It is too ridiculous. If it is so simple, why should those world-class battery companies spend so much money to develop more advanced technologies?

"Oh, I can't do it right away!"

After the Qin party was completed, it was immediately turned on. In fact, he was very suspicious of this question of Tang Feifei.

Rather than doubting the reliability of the repair skills, I suspect that my technique is not skilled enough to meet the requirements, which leads to the failure of this improvement.

Of course, at the same time, he also has a certain degree of confidence. The main reason is that this program is really very simple. Simple to true is equal to nothing to complete without modification.

"Hey, boot up, I see... full?"

When the two talked, the phone was turned back on. Tang Feifei immediately took the phone from the hands of Qin Fang, and was surprised to find that the battery of the phone was actually full again.

"Fang Fang, have you installed the wrong battery?"

Before Qin’s mobile phone battery display was indeed close to the whole space, and her own is full, but the power displayed on the phone is full, and specially waited for a few minutes, Tang Feifei also carried out some The operation of the system, but the power is still full, suddenly asked some doubts.

Qin Fang couldn't help but rolled his eyes. Can he make such a mistake?

The two batteries and the corresponding parts are carefully separated, that is, to prevent mistakes and can not be connected, as to why the power will become full, Qin Fang is also very puzzled.

"Don't be suspicious, I heard people say that when these lithium batteries are empty, they usually have at least one-third of the power, which means that the actual power used may not be two-thirds. In addition to the general display of full power, most of them have been used a lot, and now it looks like a full grid is also very normal..."

At this time, Xiao Nan, who had been "seriously listening to the class", suddenly turned around and said a word, "I said the fourth, who did you learn with this trick, so powerful?"
