    This involves the ratio of lithium battery cathode materials and the packaging of lithium batteries.

    Without any reference, without any data, I completely rely on myself to experiment step by step.

    After Gao Miao tried twice and failed to buy both times, she felt powerless.

    During this period, another experimental team member left.

    Now there are only three people in the experimental team.

    One is Gao Miao, one is Huang Kai, and the other is Luo Hao.

    It's not that Huang Kai doesn't want to leave, but all the experimental groups are full, and most of the results of the groups have been produced, and they have started to write papers. Isn't it picking peaches by inserting himself now?

    Moreover, Huang Kai himself is introverted, and he is not popular with passers-by.

    He was selected by other groups before joining Gao Miao's group

    Luo Hao is different, his purpose is to pick up girls.

    Seeing Gao Miao go to ask Chen Xiao for advice again, Luo Hao really couldn't stand it anymore.

    A freshman who has only come to the laboratory two or three times and has never done any experiments really knows lithium batteries?

    Even if the theories in his mouth are the same, a man's mouth is a deceitful ghost!

    Luo Hao said: "Miao Miao, don't get entangled in this issue. I have already made an agreement with my instructor. Wang Dongliang and the others are studying the plastic deformation of carbon steel, and they have reserved places for both of us."

    "Although their preliminary experimental work has been completed, the paper has not yet been written. We used to help write the paper, which can be regarded as contributing to the experiment. The people in their team will not say anything."

    As soon as these words came out, Huang Kai became restless. He jumped up and said, "This is impossible! Both of you are gone, what should I do? I can't do this experiment alone."

    Huang Kai shouted: "Gao Miao, I was determined to follow you back then, don't give up on me!"

    Chen Xiao couldn't help laughing when he heard the two of them arguing here.

    There are only two words for everyone's conversation - truth.

    ? Sure enough, studying for a postgraduate degree is not for outstanding research results in a certain professional field, but for the purpose of being able to combine a diploma.

    The more difficult the research object, the less people dare to do it.

    Because everyone knows that if you do this, you may not be able to produce any research results throughout the year, and it will be difficult to graduate in the end.

    Instead of this, it is better to find a simple research direction, write the thesis, pass the graduation defense, and get the diploma.

    The problem of plastic deformation of carbon steel?

    This thing is that undergraduates can find the topic when they write a thesis, right? Graduate students write this thesis?

    Chen Xiao was speechless.

    While everyone was still arguing, Chen Xiao had already walked into the operating room.

    Gao Miao's materials have indeed been bought back, and some processes have been completed.

    For example, she tried to fiddle with lithium cobaltate, lithium nickelate and lithium manganate.

    I also tried to re-model the battery package, and optimized the diaphragm in the battery according to Chen Xiao's method.

    Now the conditions in the laboratory are limited, there is no graphene, no nano-diaphragm, Gao Miao can seriously achieve this state is already very good.

    Chen Xiao couldn't help laughing when he thought of this. There was a hairy graphene in 2000, and graphene has not been invented yet.

    It was not until four years later that graphene was discovered by British scientists.

    In this era, I am afraid that even the concept of graphene does not exist.

    Just toner is just toner. Although the toner is not a two-dimensional structure, its electrical performance is not good, and it can only be used.

    What Chen Xiao has to do now is to make the best use of the materials in hand.

    Luo Hao came over and said, "Stop pretending here, we have already agreed to give up the lithium battery experiment."

    Chen Xiao looked at Gao Miao with the material in his hand, and asked, "Really?"

    Gao Miao's eyes were tangled, and he really didn't know what to do.

    In December, the first draft of the thesis will be handed in. In January, most students will go out for internships, and the time spent on the thesis will be less. In June, they will have the graduation defense.

    Many experimental groups have already completed the preliminary experimental work, and now they are fully committed to the writing of the paper.

    And what about Gao Miao?  The experiment is still in its infancy and has not been successful.

    If it fails again this time, there is really not much time left for Gao Miao.

    Gao Miao looked at Chen Xiao's sincere eyes, and thought of the fact that he chose this experiment at the beginning because he had some ideas of his own about this thing and wanted to put it into practice.?.

    Are you going to give up now?

    Lithium batteries will definitely play a leading role in the future, Gao Miao is very clear about this.

    Why are the students from Dongyang University OK, but not the students from Xiaguo?

    Gao Miao went all out and said, "Who said I gave up!"

    Just have this sentence!

    Luo Hao was speechless, "Meow meow! Are you crazy? It's already October, and the first draft of the thesis is due in two months!"

    Chen Xiao nodded and said, "I made an experiment flowchart a few days ago. If there is no problem, we can start now."

    Chen Xiao glanced at Luo Hao and said, "Senior, you also told me that this is a laboratory, please go out and talk about other things."

    Luo Hao's heart exploded, and he was taught a lesson by a freshman in his second year of graduate school!

    This man is crazy.

    Just when Luo Hao was about to explode, Gao Miao also said coldly: "If you support me, please shut up, or please go out."

    "A bunch of lunatics!" Luo Hao cursed and sat beside him in a muffled voice.

    ? No one made any noise, Chen Xiaocai and Gao Miao talked about business.

    "We currently have three cathode materials, lithium cobaltate, lithium nickelate and lithium manganate. The main reason for adding lithium nickelate and lithium manganate this time is to increase the stability and density of the battery"

    "Now we are going to spread these three materials on the aluminum foil according to a little mix ratio"

    The experiment is divided into three parts.

    Production of positive and negative electrodes, production of capacitor liquid, packaging of batteries, etc.

    During the experiment, Chen Xiao often taught Gao Miao some advanced things.

    For example, the use of nano-polymer membranes can increase the penetration of ions alone and increase the energy density of the battery.

    If the carbon powder is a two-dimensional material, lithium ions will shuttle at a faster speed between the surface of the two-dimensional material and the electrodes, and the energy density and charging speed of the battery will also increase significantly.

    Gao Miao stared wide-eyed, it was hard to imagine that Chen Xiao's theory was so reasonable, and it was much deeper than what was written in the book.

    This person is a freshman, and he is not a material science major, can you believe it?

    Chen Xiao looked at Gao Miao, smiled and said, "Sister Miao Miao, has anyone said that your eyes are big and beautiful?"

    Gao Miao hit Chen Ling on the head with a small fist, and said, "Where do you look, I'm your senior sister!"

    "Ahem!" Chen Ling could only move his eyes down, but this place didn't seem right.

    Gao Miao quickly turned around and continued the experiment.
