Chapter 130 (2/2)
Soon, the mobile phone was disassembled. As for the circuit boards and the like, Qin Fang didn't move them. On the one hand, these things are relatively precise. If he tampers with these coarse things, it is easy to cause some unnecessary damage. On the other hand, there are some deviations from his research direction. He only needs to know the structure and power supply route of the mobile phone to study the battery .
”Feifei, do you have something smaller with you? Such as earrings, hairpins and so on... ”
After dismantling the mobile phone, the next step is to dismantle the battery. However, the dismantling of this thing is a little more complicated than that of the mobile phone. Qin Fang's ”tools” are not suitable, so Qin Fang has to turn to Tang Feifei.
”Yes, yes...”
Tang Feifei immediately nodded, then pulled open her small bag and looked inside. Because she wanted to wake Qin Fang up in the morning, she went out very early. She didn't bring earrings and so on. Moreover, she always wore shawl hair, either in this way or in a braid. She seldom used hairpins, so she didn't have them.Finally, he took out a few pins and asked carefully. He was afraid of Qin Fang's anger. ”Is this OK?”
”OK, this is just right...”
Qin Fang originally wanted some needles, but he also knew that most of the girls now don't know how to sew. They certainly don't have any of these things. That's why they want to be the second best. He didn't expect that they really have them. Although they are just pins, they can at least have sharp ends.
With better ”tools”, Qin Fang's efficiency is much higher. He quickly disassembled his mobile phone battery into a pile of parts, and also disassembled the battery Tang Feifei gave him.
In fact, lithium electronic battery is a kind of battery with lithium metal or lithium alloy as anode material and non-aqueous electrolyte solution. At present, although there are many kinds of anode materials in name, they basically have commercial value, and carbon anode material is also the most widely used one.
This is true of the lithium batteries used in Qin Fang's two mobile phones.
Of course, at present, many battery companies are researching and developing lithium batteries with nano materials as anode materials, but most of them are still in the laboratory stage, and have not formed much commercial value for the time being. As for the popularization and listing, it obviously needs a long way to go.
Qin Fang obviously did not have such conditions for scientific research. At the same time, his proficiency limit also limited his research level. Even if he knew how to improve, he still could not meet the conditions.
However, let alone the strong repair skills, even in the face of such a relatively simple lithium battery facility, under such simple conditions, there are still improvement plans.
The name of the scheme given by the repair skill is called positive and negative bridging mutualism, and the principle of distance is unknown to Qin Fang. Maybe this technology has not been discovered by human beings up to now. The only thing he can do is to operate 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 a few connecting circuits that people can't understand according to the prompts, and then reassembled the battery and mobile phone.
”That's good?”
Tang Feifei was watching all the time and didn't dare to say a word for fear that he would interrupt Qin Fang's thinking. However, when Qin Fang reassembled the mobile phone and put the battery back, he couldn't help asking.
From her point of view, in addition to dismantling the mobile phone and the battery, Qin Fang simply poked the tip of the pin she gave inside the battery a few times at random. I don't know if it would be damaged by him. But if she believes that it can improve the lithium battery, she won't believe it.
It's not that she doesn't have self-confidence in Qin Fang. It's really incredible. If it's really so simple, why do those world-class battery companies spend so much on developing more advanced technologies?
”Ha ha, can we know immediately”
after Qin Fang finished, he immediately turned on the machine. In fact, he was very suspicious of Tang Feifei's question.
It is not doubting the reliability of repair skills, but doubting that one's own techniques are not proficient enough to meet the requirements, which leads to the failure of this improvement scheme.
Of course, at the same time, he also has a certain degree of confidence. The main thing is that this scheme is really very simple. It's so simple that it's really equivalent to completing without any changes.
”Well, it's on. Let me see Is it full? ”
While they were talking, the mobile phone was turned on again. Tang Feifei immediately took the mobile phone from Qin Fang's hand and was surprised to find that the battery of the mobile phone was full again.
”Fang Fang, have you installed the wrong battery?”
Before, Qin Fang's mobile phone power display was almost empty, but her own was full. But at this time, the power displayed on the mobile phone was full. After waiting for a few minutes, Tang Feifei also carried out some system operations, but the power was still full. She immediately asked with some doubts.
Qin Fang could not help rolling his eyes. Could he have made such a mistake?
He carefully distinguished the two batteries and the corresponding parts, so as to prevent them from being connected when they were wrong. As for why the power became full, Qin Fang was also very puzzled.
”Don't be suspicious. I've heard people say that when these lithium batteries are empty, they usually retain at least one third of the power. That is to say, the actual power used may not only be two-thirds, but also the full grid power. Most of them have been used a lot. Now it seems that it's normal to be full grid...”
At this time, Xiao Nan, who has been ”listening to the class seriously”, suddenly turned around and said, ”I said old four, who did you learn this skill from, so powerful?”
