    ??

    The times are progressing and the whole era is full of vitality.  It has once again witnessed the development of society more clearly, and this development is very rapid.

    But I don¡¯t know why, in 1980, Huang Shaowen could still quietly wait for time to move forward slowly, and he also enjoyed this wonderful feeling of having a new life.

    Now, I feel that everything is too slow, or not fast enough.

    ¡°Spiritually speaking, I should be considered an old man in his sixties.  Huang Shaowen didn't know very well how people in their sixties viewed the world. Even if he did, it seemed like he couldn't compare his own situation with each other.

    Anyway, I feel that the world goes by very slowly, and I kind of wish that time could go faster.

    Or maybe this is not my own idea, but a characteristic of this era.  Just like the young people in the village, they all hope to make a fortune as soon as possible.

    ¡°My mother hopes that she can get married soon and have children so that she can have grandchildren as soon as possible.

    " Xiao Xiaojing is Huang Shaowen's adopted daughter. Although in a sense, Zhao Dan's injustice has been realized, but, well, there is no comparison.

    The first thing he did when he returned to school was Huang Shaowen told Fei Yan about the patent.

    "I think I have almost researched the materials now. Let's sort them out and submit them to prepare for patent application." Huang Shaowen said impatiently.

    Fei Yan shook his head, "Neither of us are professionals to begin with. It's only been a while since we started, and I haven't figured out many things yet. Although the battery has been made, I feel that we should still do more experiments.  It¡¯s better to collect data.¡±

    Fei Yan felt that Huang Shaowen was a little too impatient and thought that he still had many knowledge points that he had not fully understood. Although he had made things and got some data, he still felt like this~~

    I feel that I am very unsure and have no confidence. I always feel that I have missed something, so I hope to learn more and understand more.

    ??Actually, Huang Shaowen felt that Fei Yan was really overthinking whether he really missed anything.  What the existing technical means can do is to select a battery with high capacity and fast charging and discharging speed based on materials. At the same time, we must also pay attention to the market price of battery materials, which is basically enough.

    In fact, you don¡¯t need to think too much about the market price of battery materials.  Because they are preparing batteries in a laboratory, not commercially.

    If batteries are produced commercially, perhaps the market price of battery materials will become an important consideration.  But now, let alone China, even Japan, which has the most developed battery industry, cannot commercially produce a new material battery in a short time.

    So when Huang Shaowen first thought about what he wanted to do, he never thought about commercialization.  This problem is not something that can be solved by just opening his mouth, digging into his pocket, and taking out some money.

    "After overcharging experiments so many times, the battery life has been roughly understood in the past few months, right? Based on the usage rate of 5 hours, is it possible to charge 2,000 times? Is it already better than the existing ones that only use 5 hours of usage?  How much better is a battery that can be cycled three to five hundred times?

    For those of them, it¡¯s half a year for the new one, half a year for the old one, and another half year for maintenance. In theory, this should last at least seven or eight years, right?  You have also studied lithium cobalt oxide, and the high temperature test is one or two hundred degrees higher than that of lithium cobalt oxide, no problem.  This is enough to prove that this battery material is currently the best material.  "

    Huang Shaowen briefly talked about the advantages of lithium iron phosphate.  Fei Yan also knew this, but he was a little unsure.  Even though Huang Shaowen told him that what they have completed now is the best, for Fei Yan, he did not learn it step by step in a down-to-earth manner. He only became a monk halfway and read a few thesis materials handed over by Huang Shaowen, and then learned while doing it.  While tinkering with various material preparation issues raised by Huang Shaowen.

    First, I completed one according to other people¡¯s procedures.  Then we got out the lithium iron phosphate proposed by Huang Shaowen, and then replaced the original cathode material with this lithium iron phosphate.

    Then after a certain amount of charging and discharging experiments, Huang Shaowen announced that the battery was completed.

    "However, during the preparation process of lithium iron phosphate, the iron oxide was reduced to elemental iron in a high-temperature reducing atmosphere. I have made batteries several times before, and after they were made, short circuits always occurred. If you hadn't said,  Let me, it will take a long time to find the reason. Finally, you also said that this is not easy to avoid.

    If this is the case, it will always produce a battery that is prone to short circuit, isn¡¯t it bad?  "

    Although the work of those who follow cats and draw tigers seems to be a bit simple, it seems that there are some mistakesscore.  But Fei Yan knew very well that during the preparation process, there were still many problems that he could not solve by himself.

    There are many detailed issues. Even after the battery preparation was completed, some problems occurred. I couldn't think of where the problem occurred for a while, but Huang Shaowen could always tell the problem right away.

    In some places, according to Fei Yan's understanding, the problem can only be found if the previous preparation process is taken out and strictly followed again, but Huang Shaowen can definitely tell where the problem is.

    Fei Yan thinks Huang Shaowen is very good at this.  I wanted to ask him how he knew the cause of the problem and how he knew the solution.

    ??Every time Huang Shaowen told him that he arrived at the result through general logical reasoning, combined with the characteristics of element particles he understood, and after certain analysis.

    Fei Yan didn't know how serious he was, and wanted to learn from Huang Shaowen's way of taking things lightly and taking things lightly.  Unfortunately, until now, the more he studies, the more Fei Yan realizes that he seems to know too little.

    If you want to reach the height of Huang Shaowen, you have to put in a lot of effort.  This is why Huang Shaowen seemed a little anxious, but Fei Yan wanted to do more experiments.

    Huang Shaowen naturally understood that he had been "favoured" by Fei Yan.  But Huang Shaowen really couldn't tell Fei Yan why he could find the problem right away and come up with a solution.

    Because he had seen all this and already knew it. If he wasn't afraid that Fei Yan would directly classify some of his actions as incomprehensible and directly mystify them, Huang Shaowen could even tell Fei Yan what he must pay attention to during the experiment.  place.

    Huang Shaowen kept telling Fei Yan that he didn¡¯t know much about chemistry, and he really didn¡¯t understand chemistry compared to Fei Yan himself, so he hoped Fei Yan could help more.

    " If he promised that he didn't understand anything, but ended up intervening in Fei Yan's experiments and constantly guiding Fei Yan's experimental process, wouldn't this mean that Huang Shaowen's reason for inviting Fei Yan before was completely untenable.

    If you are gentle, people will think you are humble; if you are serious, they will think you are pitiful.

    This is not good. After so many years of life experience, Huang Shaowen thinks that his emotional intelligence is pretty good.  (Remember the website address: www.hlnovel.com
