Chemistry

* * *

3 p.m., N1 test area.

Near the center of the tall gym building was a large group of people preparing for testing.

The work of the Korean SDI to apply the improvements that were made during the first meeting was under the supervision of the ship-owner and former employees, while KG Chemistry was also conducting a field trip.

“One team leader. ”

Park Geun-soo, who was touching the camcorder a little distance from the center, turned to Jungwoo.

“Shouldn't we be watching the work? ”

“You know, the X.O. Our analysts are doing it from here, when it's quiet. ”

Park Geun-soo nodded and turned the lens in his hand to the container in front of his eyes. The same structure that caused the problem in the solar power plant was thoroughly captured on the screen.

Ducky.

Jungwoo, who opened the inner door, pushes his head in. Don Park Geun-soo approached Jungwoo once around the structure.

“Did you find anything? ”

“We've only found what's in the data yet. Let's take a closer look inside. ”

After Jungwoo disappeared, Park Geun-soo followed him into the structure.

The room had little light, so Cam switched to Night Vision mode. A careful sweep of the lithium-ion cell modules through a densely piled space appears on the screen.

“This morning. Why did the captain of Hansung say to follow Captain Lim Wu's orders more than his own? Isn't this just a precaution to transfer responsibility? ”

“Well, I didn't think he was smart enough to do that. Don't worry too much. ”

Jungwoo, who took out a voltage-checker with only a palm of his hand, gestured behind his back to Park Geun-soo.

“Can you keep your distance for a moment? If we check the voltage manually, we could get electrocuted. ”

“Aigoo, how much current is flowing through the scanner. ”

“No.”

Jungwoo said again with a serious face.

“It's really dangerous, so please stay back. ”

There was a glint that fractured from Jungwoo's hand that brought the voltage checker near the lithium ion cell.

“Ugh.”

Surprised Park Geun-soo steps back and pulls Cam's zoom. An intermittent spark continues to pop from the inspector in Jungwoo's hand.

“A little stronger. No, don't touch the metal electrode. That's right."

With every splash of spark, Park Geun-soo felt a strange feeling in Jungwoo's face that lifted his head and muttered something. An electrical flame that continued to blaze around Jungwoo extended the branch of current only in a constant direction as if it had any intention.

As I breathed and watched, someone tapped my fingertips with Park Geun-soo's shoulders.

“Excuse me.”

The flinching applause turns its head. A well-dressed woman smiles and greets.

“What's going on, Chief Jung? ”

“I'm here to see Chief Lim Wu. ”

During the conversation, Jungina's eyes widen as the spark fries from the inside, as if welding. Park Geun-soo quickly said that my team leader was making a bad scratch on the test structure.

“Wait. I'll get it to you. ”

Bang.

Park Geun-soo, who closed the container door, looked at Jungwoo. I was focusing on the lithium ion module just to see if she didn't know what she was visiting.

“This response will keep you safe, right? ”

“Sir.”

Jungwoo's head turns to the call of Park Geun-soo.

“Are you all right? ”

“I'm fine with my insulating gloves on. ”

Jungwoo smiles and shakes his gloves. Park Geun-soo pointed to the door with his hand.

“Jung or the team leader is outside. He wants to meet a team leader. ”

“Is that so?"

Jungwoo, who put the checker in his pocket, grabbed his hand and approached Park Geun-soo.

“I think I've done about all the tests I can do here. Let's get out of here.”

Sweet.

Jungwoo stepped out of the ESS container and dragged a bunch of dust stars from the inside out. The guys who were shooting around the room were excited and scattered in the air.

‘We don't have all the problems, but we do have the culprit who turned up the temperature when the generator started. ’

Certain molecules that wandered around like they waited to stir up the compound that was building up inside the lithium ion module.

Jung Jina walked in front of Jungwoo who was walking, thinking about it in his head.

“Captain Lim Wu. ”

The beauty of the nostrils was plunged into the view of Jungwoo, which was out of the molecular world.

“May I help you? ”

“Because I said something out of the blue without consultation. After discussing it with his secretary, he was worried that he would become a liability and become the lungs of Chief Lim Woo. ”

“So, if the project fails, you're going to blame me? ”

Jung Jina was embarrassed by Jungwoo's reaction, and she shakes her head to the left and to the right.

“Not at all. Never.”

“I'll take your word for it. Busy with the analysis, then. ”

Jungwoo responds lightly and walks to where the KG Chemistry team members are.

“Bo-young! Where'd you put the heat treatment kit and powder compound box? ”

“Lab 3. I put all my gear in there. I'm looking for · ·”

“No, stay here. We need to keep an eye on this test. ”

Jung Mina glanced at Jungwoo's back, which disappeared out of the building.

In 10 minutes.

Jung, who was in the N1 test area with the box, confirmed that the test was about to begin and approached Song Bo-young's side. Song Bo-young kicked her tongue toward the setting of the heavy looking box beneath her feet.

“I'll do it. ”

“It's more urgent this way. Did you check the exam prep? ”

“It's not hard to check. Here you go."

Song Young-young shakes her notebook with something subtly written.

“Primary storage of power supplied through that transmission line to ESS, and pulling it out through the detector. The conductor also demonstrated the console operation · · · · · ·. ”

Song Bo-young, who described the equipment with her finger, pointed to the members of the Hansung SDI team who were fitting the battery pack to the test unit.

“Do you see that? I reflected all of Mr. Jungwoo's opinions in that short time. It wasn't one or two. ”

“Shouldn't be too hard. The data shows that everyone is quite good. ”

“Are you complimenting yourself for pointing out all that data, now? ”

Jungwoo shrugs as if to look at it with a playful little smile.

“What a wreck for a humble team leader. ”

“Chi. I met this beautiful charlatan, and she was very fascinated. ”

“Do you find anything fascinating? I admit she's pretty, but she's not making my pockets thicker because she's a punk. ”

He said, "You're going to inherit the Han Star SDI, and if you get to know him, you'll only get thicker. ”

Jungwoo's eyes widened.

“Was it that high? ”

“You didn't know that, did you? ”

“Charging in. If I hadn't stepped out of that meeting, we'd all be in real danger. ”

Song Bo-young's gaze was towards Jeong Ina. Every time I worked, the elites of the Hansung SDI were busy praising themselves by staying close to each other.

“What kind of risk did you take to gain Jeong Inna's trust? ”

“Trust seems to have been earned, and in a way, it's because of the crisis that will end your deputy chief's tenure in just one day. Meat grade plus 1 because of me. Ground. Final verdict. ”

“What do you mean · · ·”

“Huh? Here we go. ”

The members of the Hansung SDI team who completed all the set-up gathered to the console controls.

A Korean employee put on a loudspeaker.

- Transformer pressurization in progress! Do not leave the safe zone!

Everyone's attention was drawn to the ESS device.

Koh Sang-gun, who was manipulating the console, smiled satisfactorily at the young eyes of Jeong Inna who was watching him.

At the meeting, I took a punch from Lim Wu, but I was quite good at conducting two hours of corrective work. In addition, a groundbreaking device has been attached to the module.

A lithium sulfide sample that was ambitiously designed and brought to us was borrowed from the state-of-the-art current stabilization system, the shell, even though it became unusable. This technology is not just about KG chemistry.

KG electrons could never keep up.

Duwoowoowoowooo ―

An incoming current along the transmission line has spilled into an ESS facility equipped with lithium ion cells. The frequency graph representing the width of the current on the monitor attached to the console fluctuated once.

“Representative. Is this okay? ”

I answered the question of surrogacy of rigid wood as if it were natural.

“It's just a projection of the irregular energy flow of the solar panels. Once the stabilization system is operational, it's gone. Don't make any unnecessary assumptions, but don't make me anxious, boss. Stay away from there. ”

The surrogate looked directly at Jeong Yina's voice and shot at him with the burning eyes of the eagle.

“You · · ·”

“Why?”

Since there was nothing to argue with, the valet bites his lip tightly and retreats. Meanwhile, the ESS device's charge rate ran toward 100%.

Ko Sang-gun proceeded to manipulate the console and send stored current to the detector. And I proudly reported to Jeong Inna.

“Mr. Jung. that if you keep the green light on that detector for the next five minutes, it's going to be a reliable supply of peak shifting, reserve power that can respond to urgent power demand. ”

“Oh, really? ”

“At the same time as solving problems, we will build an ESS facility using the technology of Hansung. KG chemistry won't get in the way. ”

Jungina looked at the detector with a more interested glance.

By the time three minutes had passed, the power supply graph in the monitor suddenly fluctuated to a large extent.

Phoebic.

The boat conductor and Hanjeon staff who were watching the test on one side of the day looked at the monitor.

“What is the warning? ”

When asked by the conductor, he groaned as he examined the figures.

“Oh, the temperature's rising. ”

“How much?”

“0.5 degrees on average. ”

“The figures are still in error.

He considers it to be an environmental phenomenon such as hot weather and turns his attention away from the Stop button in the center of the console.

More than 30 seconds passed.

Pibibbivic ―

“0.7 degrees, 0.8 degrees. ”

As the temperature increase widened, the conductor rushed to the side of the Gosansangohan.

“I think we should stop and review. ”

“Senior Vice President. Still free to first degree · · · · ·. ”

Failure to perform a power supply load test for five minutes through the detector did not mean that the previous three minutes were stable. Ko Sang-gun wanted to hold off for as little time as possible, but the conductor pressed the stop button without hesitation.

The current coming in and out of the transmission line was blocked and the ESS charge rate going back and forth between 97 and 98% dropped sharply.

Ko Sang-gun sighed deeply and looked into Jeong Yina's eyes.

“Team Leader, I think there was a problem with Limited Woo's offer. ”

“Problem?”

“Without it, the temperature couldn't have gone up like this. I'm going to pretend that I haven't followed their directions before. ”

“Representative Go said you were perfectly prepared earlier. ”

“It · · ·”

“If it wasn't perfect, why didn't we find it before we started? ”

On account of Jeong Inna, while Goshen became mute with honey, the ESS charge rate fell below 50%.

And...

There was a spark on the ESS facility side that combines small battery cells.

Pazier!

Everyone was surprised when the blue high pressure current could be seen between the console unit and the ESS facility. The spark that splashes and splashes along the wire becomes closer to the console in an instant.

I was manipulating him, and he suddenly stood up in a frightening look.

“Nobody move! ”

Someone rushes out of the front of the console screaming.

“It's safer there. Even if you don't see it, there's electricity running through the surrounding equipment, so don't touch anything! ”

High-pressure currents, sparks, and the wire that started to smoke reached out to something he had in his hand. The current that was spreading across the wire along with the terrifying light gathered in his hands.

Jiuy-yi!

Reflexively, Jung, who closed her eyes, looked at the back of a person standing two steps in front of her. It was the back of a familiar man.

“Chung or Team Leader, Are you hurt? ”

“Oh, no. ”

In front of the man stretching out his arms toward the ESS facility was a current that fluctuated parr. I couldn't keep my mouth shut because it looked like it was dealing with blue flashing currents.

Jungwoo looks at the scrubber in his half-burnt hand and turns his head toward the boat conductor.

“I don't think this equipment is going to hold much longer, could you flip the transmission line switch again? ”

“What do you mean, back up? ”

“Oh, it's hot. This glove is insulated, but it's not flame-retardant. Please hurry up before you finish your hand. ”

The boat conductor pressed the start button. Recharge rate fell below 50% again. Then the current that was hovering in front of Jungwoo's hand gradually faded.

“There you go.”

Jungwoo walks to the console, dropping his charcoal checker on the floor.

“That was a close call. Leave the battery in this condition for natural discharge, and let the insulated person manually disconnect the ESS module. ”

An employee of Hanjeon pulled out the thick wires that were connected to the appliance equipped with battery cells.

The boat conductor asked Jungwoo with a ten year face.

“What's going on here? ”

“I don't know, but it looks like certain compounds floating in electrolytes inside the cell are deforming in the process of stockpiling and discharging electricity. When the current completely dissipates from the modified part, the temperature rises abnormally. Common sense says we should stay away. That's why it's so hard to analyze. ”

“Don't tell me that's... ”

“Yes, by the looks of the process, I can see it clearly. This seems to be the main problem with the Hokkaido fire. ”

Jungwoo uncovered the cause of the accident, even though the boat conductor's face was revealed. When I saw it, I interrupted with a smile.

“Is it time to find out why? The best company in the country got together to get rid of the internal batteries anyway. Mr. Lim Wu, isn't it because the improvements you proposed are unstable? ”

Jung took off his insulating armor without answering, put it in one armpit, and manipulated the keyboard in front of the monitor to examine the graph.

“I don't think I have anything to say after I stab you. It's a nanothin film. It's not hard to reflect right now. If you went to lithium sulfide, you'd have stability. ”

While laughing at Jungwoo, Ko Sang-gun said to Jeong Ina, who was approaching.

“Mr. Jung. Since Mr. Lim Woo caused the accident, it is unlikely that we will be able to follow his instructions first. ”

“What if this accident...?"

“Of course it's their fault. ”

The atmosphere seemed like Jungwoo's responsibility, even though he was talking alone, the team members of KG Chemistry who were watching in one place lit their eyes. Song Bo-young, who was standing in the gap, was about to step forward with her fist burning, and said, "Oh! ’and found a part of the monitor.

“Found it.”

“What?”

“The cause of this accident. Look here."

Along Jungwoo's finger direction, Gossan turns his head to the monitor. Jungwoo continued to say.

“If you look at the graph here, when there was an accident that almost shocked everyone in the area, the frequency fluctuations stabilized. ”

“What's that? ”

“Don't you get it when you see this? ”

“Who is this kidding · · ·”

I stopped looking at the monitor.

“· · · This, I shouldn't do this. ”

Everyone's attention is drawn to the muttering of high spirits.

Jungwoo looked at the solidarity without a word and lightly explained it to Jungina in an unfamiliar way.

“The battery cells used in this test were the same equipment that we had in the war, and of course, there was a problem with Hokkaido. It was supposed to be unstable inside the voltages. But that ESS is equipped with special equipment that can really fix the voltage problem. ”

It swallows the saliva.

“There was an accident and you hid it for three minutes. What do you think of this equipment, Representative Go? I'm not very good at proposing or making things like this. I'm not a mechanical engineer, I'm a chemist. ”

“It · · · · · · · · · · ·. ”

The highness was silent.

“The loudest one wins the fight. You have to know the cause first to be wrong. I think my voice is a little louder right now, so let me just say one more thing. If I hadn't reflected on the improvements I had suggested to Jeong or the team leader, there would have been a much worse power leak than just the accident. If you don't believe me, try experimenting. Oh, I can't save you like before this time. Our expensive equipment exploded with overvoltages. ”

It was the voice of Jojo and calm Jungwoo, but for Gosang-gun, it was like the power of the blue ceiling. In front of Jeong Inna, there was no dog like this.

“That's all I have to say. Deputy Director Song Bo-young.”

Song Bo-young was called by Jungwoo “Yes?” I responded reflectively.

“We've identified the cause in the analysis group, so let's go to the meeting. Let's get ready for our test tomorrow at this hour. ”

Jungwoo bows to the boat conductor and gathers his team members and disappears.

After taking a big knockdown to KG chemistry, the Hansung SDI began to withdraw its equipment following the attention of Korean employees.

The next morning.

In the corridor of room 3, there were a lot of members of the Korean SDI team gathered to watch the work inside.

“What the hell, that team leader. How is it possible to do that without measuring? Are you kidding me?”

“What kind of mixing is done in a second? You're just trying to do it. ”

I was mostly watching Lim Woo work alone in the corner.

Ko Sang-gun looks at his colleagues as pathetic as he's been plagued by harassing restrictions since yesterday's incident.

The limited time work that was constructing the test cell was at the level of the laboratory's artisan, which was rapidly and accurately itself. The gap between colleagues was large enough that they did not notice it.

However, it did not mean that he was better off than his colleagues, knowing the level of confinement. I had worked on a project with a team of artisan scientists like that, and I just realized that the work was never a joke.

Jiaying.

My phone rang and held my hand. A call from a senior at a research center. I retreated to one side of the corridor and took it right to my ear.

“Yes, sir. ”

- Hey, there's a couple of people in there, and they want another assignment. And the chief researcher? How many pies are there?

“That's not true, but at this rate, you may fail to build a good rapport or a team leader. ”

- No, why? Did the head researcher come to the group for KG chemistry? Even so. You took all the information in advance to the report.

“Limit Woo. This is the problem. I've never seen a chemist with this kind of integrated knowledge and sense before. ”

When I explained in detail what happened on the first day, I heard a laughter over the phone.

- You took all nine of our papers? That's not even for the warden.

“It's all true. ”

You got a plan?

“At the moment, there is no answer but senior support. ”

- You're trying to take him out.

“If we're not going to die, so be it. ”

I'll check with the warden. We'll all be dead by then.

He sighed of relief.

- By the way. Do you have feelings for her?

In this question, the sigh of relief turned into a sigh of despair.

“I had an unexpected situation. ”

- Why else?

His gaze was on Jungina, who was with the KG chemistry team in the research agreement room.

Mixed with binders, carbon black and solvents, the refinery applied to an aluminum thin film scattered powder cell material with a teaspoon over it.

“Here, sunbae. ”

While Songpoyong was receiving it and undergoing heat treatment, the refining placed another thin film after heat treatment onto the table and inserted pencil-shaped electrode material at the extreme end.

A thin film was placed in a transparent box filled with argon gas and hand placed in an external hermetic rubber glove to be reborn as a flat cell.

“Is this a nanothin film? ”

I shook my head at Jung Ina's question, who was constantly keeping her eyes open for work.

“Now it's a normal lithium-ion cell. ”

“Then · · ·”

Jungwoo takes the ceramic separation layer from the team member holding his hand on the other side and joins them. Then three or four drops of electrolyte were dropped into the spot to soak the thin layer of separation film.

“Is it a nanothin film now? ”

“Not yet. ”

A team member with a rigid thin film tucks it into the press and closes it tightly.

“There you go.”

“A member of my team said it's hard to make, but one team leader is fast. ”

“We have great colleagues. ”

Song Bo-young approached next to Jungwoo, who began to mix and apply the mixture to the aluminum base thin film again.

“Mr. Jung. Listen to one of the bosses. You can't make it without that complicated mix-up that no one else can. ”

“Oh.”

Jungina glanced at Jungwoo. Jungwoo pretends to concentrate on the task because it is too burdensome, and quietly asks.

“But will you still be here? ”

“I have a lot to learn. ”

“Learning is good, but the members of the Korean SDI team in the hallway have been doing that for 30 minutes. ”

“I'm waiting for someone to come from the headquarters. I have until then. Oh, you're interrupting me. I'll stay put.”

Jungwoo sighed because he thought he should be here the whole time. After hearing from Song Bo-young how the members of her team are participating in the project, even talking to Jeong felt burdensome.

‘So am I. Are you worried about becoming a chaebol son-in-law? ’

This will be called 'Drinking Kimchi Soup’. Jungwoo took a deep breath to focus on work, not worthless thoughts.

About 10 minutes later, I heard a voice calling Jeong Inna outside the door.

- Sir, Dr. Ryu is here!

Jungina got up from the chair.

“I have to go. Good tour. ”

She bowed down and thanked the members of the KG Chemistry team at work, and approached Jungwoo's side.

“One team leader. ”

“Yes?”

When Jungwoo looked at it, Jung was a little hesitant.

“The chairman of KG Group is hosting a birthday party this weekend. I was invited, but I didn't know anyone from KG. Would you mind · · · joining us? ”

In this horse, Song Bo-young, who was working on the heat treatment, missed the tweezers in her hand.
