Chapter 130 Improving Lithium Batteries
However, the speed at which Qin Fang turned the pages of the book was really frightening. The students around him couldn't help but look over, with a clattering sound, and all of them looked quite curious and surprised on their faces.
"Fang Fang, are you okay..."
Tang Feifei also felt something was wrong, pushed Qin Fang gently, and asked with some worry.
"It's okay! What's wrong?"
Qin Fang didn't feel anything. He didn't turn his head. He was still reading the book intently, and then quickly turned the page.
"Are you sure you're okay?"
But the more this happened, the more abnormal it became. Tang Feifei held Qin Fang's hand to stop him from continuing to turn over, and asked in an extremely uncertain tone.
"I'm really fine!"
Only then did Qin Fang notice the looks in the eyes of the people around him. He immediately smiled bitterly and looked at the speed at which he turned the book. In just a short time, he had already gone through dozens of pages. A textbook only had two or three hundred pages.
, if he continues to scroll, he will probably have finished it all before the lesson is over.
"It's okay, don't scare me like this next time!"
Seeing that Qin Fang had finally stabilized, Tang Feifei breathed a sigh of relief and stopped paying attention to the lecture. She just held Qin Fang's hand, fearing that he would do the same stupid thing again.
In this way, it was obviously impossible for Qin Fang to continue learning English, and 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, which made even the punctuation marks memorable.
Qin Fang suddenly felt quite bored.
Looking at Xiao Nan next to him, he was not sleeping. He seemed to be listening to the class very seriously. Naturally, it was not easy to chat with him. After thinking about it, he took out his mobile phone and planned to use her to pass the time.
"Holy shit, my phone is going to run out of battery..."
It's a pity that as soon as Qin Fang took out the phone, he found that the battery was low. If he really started playing with it, he would probably die in a few minutes.
"Use my mobile phone to play! Or I will give you the battery and you can replace it..."
Tang Feifei was very considerate and 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, but since Qin Fang used Apple, she also specially changed it to one with the same model, configuration, and even some ringtone settings as Qin Fang.
"By the way, I remembered..."
Seeing Tang Feifei turn off her mobile phone to take out the battery, Qin Fang immediately remembered that he had been thinking about researching the improvement technology of lithium batteries, but his repair skills were not very proficient and he had never started to do it. At this time, he was free.
In panic, Qin Fang planned to take action.
"Fang Fang, what are you doing?"
Tang Feifei had just taken out the battery of her mobile phone and was about to hand it to Qin Fang, but she was surprised to find that Qin Fang was dismantling his mobile phone.
"Do you remember what I told you last time? Let me study it first!"
There were many talkative people here, and it was hard for Qin Fang to be too straightforward, so he whispered something in Tang Feifei's ear.
"Oh! But you don't have tools..."
They are here for class. Apart from paper and pencil textbooks, there really is nothing else. "How did you take apart the mobile phone..."
But before Tang Feifei finished speaking, she was surprised to find that Qin Fang had already disassembled his mobile phone, and was even preparing for further disassembly. It seemed that he did not want to restore the mobile phone to its parts.
No intention of giving up.
"Hey, who said there are no tools? Isn't this right?"
Qin Fang smiled and held up the nail scissors, ear picks, keys, buckles and other things on his hand. He used these things to dismantle a still brand-new mobile phone into a pile of parts.
"That's okay..."
Tang Feifei looked surprised. She had never seen someone with such skill, using these completely irregular "tools" to dismantle a precisely assembled mobile phone.
Soon the mobile phone was disassembled. As for the circuit board and the like, Qin Fang did not touch it. These things were relatively delicate. If he fiddled with these thicker things, it would easily cause unnecessary damage.
Secondly, it was somewhat deviated from the direction of his research. He wanted to study batteries, and he only needed to understand the structure of the mobile phone, the power supply route, etc.
"Feifei, did you bring something smaller? For example, earrings, hairpins, etc..."
After disassembling the mobile phone, the next step was to disassemble the battery. However, disassembling this thing was a little more complicated than the mobile phone. Qin Fang's "tools" were not suitable, so Qin Fang had to turn to Tang Feifei for help.
"Yes, yes..."
Tang Feifei nodded immediately, then opened her small bag and rummaged around inside, because she had to wake Qin Fang up in the morning and she went out very early. She didn't have any earrings or anything like that.
She wears it, and she has always worn her hair around her shoulders, either hanging it like this or tied into a small braid. She rarely uses hairpins and naturally does not have any.
Finally, he took out a few pins and asked cautiously, as if he was afraid that Qin Fang would be angry, "Is this okay?"
"Okay! This is just right..."
Qin Fang originally wanted some needle-like things, but he also knew that most girls nowadays don't know how to sew and thread, so these things must not be available, so he settled for the next best thing. Unexpectedly, there were actually some, even though they were just pins, but
At least it has a pointed end.
With better "tools", Qin Fang became much more efficient. He quickly disassembled his mobile phone battery into a pile of parts, and also disassembled the battery that Tang Feifei gave him.
.
Lithium electronic batteries are actually a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Although there are currently many kinds of negative electrode materials for lithium batteries in name, they basically have commercial value and are also the most widely used.
It is the carbon negative electrode 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 using nanomaterials as negative electrode materials. However, most of them are still in the laboratory stage and have not yet formed much commercial value. As for popularization and listing, it obviously needs to go further.
It's a long way.
Qin Fang obviously does not have such scientific research conditions. At the same time, his proficiency limit also limits the extent of his research. Even if he knows how to improve, he still cannot meet the conditions.
However, let alone, the power of repair skills is reflected in moments like this. Even when faced with such a relatively simple lithium battery facility, under such crude conditions, there is still an improvement plan.
of.
The name of the solution given using the repair skill is called positive and negative pole bridge interchanging. Qin Fang does not understand the principle of distance. It is even unknown that this technology has not been discovered by humans until now. The only thing he can do
The best thing is to operate according to the improvement plan given by the repair skills.
This improvement plan is relatively primitive, and the operation method is also very simple. Qin Fang just followed the prompts and simply set up a few incomprehensible connection loops inside, and then reassembled the battery and mobile phone.
stand up.
"Is this good?"
Tang Feifei had been watching from the side, not daring to say a word, for fear of interrupting Qin Fang's train of thought, but when 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 mobile phone and battery, Qin Fang simply poked the battery a few times with the tip of the pin she gave her.
Bao doesn’t know yet, but if you let her believe that this can improve lithium batteries, she won’t believe it even to death.
It's not that she has no confidence in Qin Fang, it's really unbelievable. If it's really that simple, then why do those world-class battery companies spend so much money to develop more advanced technologies?
"Haha, we'll know soon if it works or not!"
After Qin Fang finished, he immediately turned on the computer. In fact, he himself was very doubtful about Tang Feifei's question.
It's not that I doubt the reliability of the repair skills, but that my techniques are 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 indeed very simple, 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 nervously took the phone from Qin Fang's hand, and was surprised to find that the battery of the phone was full again.
"Fang Fang, did you install the wrong battery?"
Qin Fang's cell phone's battery power display was indeed close to empty before, but her own was fully charged. However, at this time, the battery displayed on her phone was full. After waiting for a few minutes, Tang Feifei also did some
The system was operating, but the battery was still full, so he asked with some confusion.
Qin Fang couldn't help but rolled his eyes. Could he have made such a mistake?
He carefully separated the two batteries and corresponding parts to prevent them from being connected by mistake. As for why the battery was fully charged, Qin Fang was also very puzzled.
"Don't be suspicious. I've heard people say that in fact, when these lithium batteries show that they are empty, they usually retain at least one-third of the power, which means that the actual power used may not be more than two-thirds.
In addition, most of the batteries that usually show full power have been used a lot, so it is normal for it to appear to be full now..."
But at this moment, Xiao Nan, who had been "listening carefully to the lecture", suddenly turned around and said something more, "I mean, fourth brother, who did you learn this trick from? It's so powerful?"
