Orion Crest, Series_1

Chapter 61: Beautiful and deadly dendrite

　　Orion replied, "I'll do it."

　　The system didn't specify who had to operate the experiment, as long as the experiment was done once and then the required data was collected. However, for the purpose of learning, Orion still wanted to do the operation himself.

　　After all, what the books taught him was all theory, and only by doing the experiments with his own hands would he be able to turn that legendary technology into something real.

　　Ceremonially changing into a white coat, Orion slightly took out the posture of a scientist, took a deep breath, and reached for the sample box containing the experimental materials.

　　However, before his hand could touch it, it was snatched away by a quick-eyed Matt.

　　"It's better for me to do it, watch from the side."

　　Without saying a word, Matt took over the initiative of the experiment, leaving the dumbfounded Orion standing by the side.

　　Looking over to Bob, who was clutching his arms, he shrugged helplessly.

　　"Don't mind it, it's just the way Matt is, the apparatus here is like his wife, it's more important than him ...... the first time, you might as well watch him do it all over again."

　　Matt did not return his head, then said, "Doing experiments is not like doing maths, miscalculating a decimal point and changing it can still be followed by calculating, a small detail in an experiment that is wrong can lead to the whole experiment being scrapped. Of course, I'm more afraid of you to scrap the experimental equipment ...... give me your design of the experimental process then."

　　"Here it is." Orion quickly took out the piece of A4 paper.

　　The experimental steps that the system required to be carried out and the experimental data that needed to be collected, he had written them all on it.

　　Matt took the A4 paper and scanned it, nodding, "The design is quite professional."

　　emmm......

　　Well, it was a system design after all.

　　Orion had a subtle expression and didn't say anything.

　　......

　　The procedure of the experiment was simple, starting from making the cell to observing the phenomena.

　　95.7% graphite was used as the anode material, the binders were sodium carboxymethyl cellulose (CMC) and styrene butadiene rubber (SBR), and the collector was copper foil. The thickness of the graphite layer was 90 μm, LiFePO4 was used for the positive active material, and the collector was aluminium foil.

　　As for the diaphragm, a three-layer diaphragm of Celgard 2325 was used, with a thickness of about 25μm.

　　In order to prevent material oxidation, all operations were carried out in a glove box filled with argon gas.

　　Of course, not only to prevent material oxidation, but also to prevent the LiPF6 component in the electrolyte from reacting with water in the air to form hydrofluoric acid.

　　Hydrofluoric acid is something that anyone who has studied high school chemistry knows about. And anyone who's spent time in a silicon-based microelectronics lab should also be well aware of how dangerous this stuff is.

　　Judging from Matt's operating procedure, it was obvious that he was much more professional than Orion, the theorist.

　　Soon, the samples were made.
