Chapter 143 Test Successful
"That's right!" Yang Dong nodded after hearing what Xu Qiang said.

"As long as we have my technical equipment and the qualifications and manpower you provide, we can make a fortune with small profits and quick turnover." Xu Qiang smiled and continued, "Although I am young, I have heard an old man say that in business, it is not about who can make more money in a short period of time, but who can do it longer. Small profits and quick turnover, steady progress is more important than fast progress."

"Boss Xu, what you said is very good. Sometimes I am impatient and short-sighted. I have learned a lesson today..." Yang Dong said sincerely.

"In fact, Village Chief Yang, you are not a simple person. Given the conditions in your village, no one has starved to death in the past ten years. This is not an easy thing. Ultimately, it is all thanks to you, the village chief." Xu Qiang also began to praise Yang Dong.

"To be honest with you, I don't want to be the village chief. Every time I open my eyes and think about the hundreds of people in the village waiting to eat, I feel overwhelmed..." Yang Dong sighed, and then said: "In addition, for the sake of the overall situation, I also owe a lot of people. For example, your big black bull. If I hadn't pushed all the things to him, at least more than a dozen laborers in the village would have to go in. They are the main labor force in their families... I really had no other choice..."

"Okay, I get it. It's over. Big Black Bull is doing well with me. You just need to take care of his family in the future." Xu Qiang could see that Yang Dong was definitely not acting. It was indeed not easy for him to be the village chief.

"That's for sure. He only has one mother. I used to send food to his house quite often."

"I won't say anything else. Since we have already started cooperating, we must unite. As long as we do a good job in this stall, I will not only give you a registration fee, but also lead your village to become rich collectively. Every family can eat meat every meal, and every young man can get married!" Xu Qiang said with a raised eyebrow.

"I don't quite believe what you said. What kind of family eats meat every day?" Yang Dong said with a smile.

"This is actually the kind of life we ​​live here." Xu Qiang said, and shouted to the outside: "Erhu, bring the food over quickly!"

"coming!"

The next moment, Erhu, Liu Jun and others brought up the fried dishes and some cold dishes.

Seeing more and more dishes being served, including some "hard dishes" like chicken and fish, Yang Dong was stunned.

He didn't expect that the food at Xu Qiang's peat field was so rich, just like eating in a restaurant.

"You came today, so I asked him to cook two more dishes tomorrow, but it wouldn't be much different at other times." Xu Qiang said, taking out a bottle of Si Te wine from a box in the corner, unscrewing the cap and filling his and Yang Dong's glasses, and said, "Boss Yang, I wish us a happy cooperation and great fortune in the future!"

"Do you usually eat so well?" Yang Dong asked Erhu.

"That's about right. There's meat in every meal anyway." Erhu said straightforwardly.

"You...are a good person..."

Looking at the food on the table, Yang Dong was stunned for a moment and then looked at Xu Qiang and said, then he also picked up the wine glass.

The next moment, their glasses clinked together...

……

On Monday morning, after Xu Qiang arrived at the factory, he went directly to the battery workshop.

Last week, with the help of Huang Baoshan and Chen Qingcai, Xu Qiang finally made the two electrodes of the perchloric acid battery, and he will start preparing the electrolyte today.

The electrolyte of this battery is mainly sulfuric acid.

In fact, Xu Qiang's perchloric acid battery is a thermal battery. The principle is that sulfuric acid and iron react violently to instantly generate high temperature, which can reach about 650°C. This high temperature will reach the melting point of the dissolved salt, which is 500°C, thereby activating the battery. This is also the general working principle of thermal batteries.

It is precisely because of this special function that thermal batteries have a very long shelf life, generally about 20 years. Nowadays, the storage time of ordinary artillery batteries is only about three years, at most five years. If this time limit is exceeded, the battery will be low on power. The use of thermal batteries can greatly increase the storage life of these equipment, which can be said to be a huge improvement in military technology!
And because thermal batteries are one-time discharge batteries, their specially treated electrodes and solvents can withstand the effects of extreme temperatures better than conventional batteries, so they can work well even at extreme temperatures, which is naturally one of their biggest advantages.

In the battery workshop, Xu Qiang asked for a large bottle of sulfuric acid and several other solutions, and then returned to the scrap warehouse.

Compared with other places, the scrap warehouse is less crowded and more spacious. There is a large open space in the backyard that can be used for experiments. Xu Qiang plans to conduct battery reaction experiments here. One of the important measurement indicators is specific energy.

The so-called specific energy is an important parameter to measure battery performance. It refers to the energy provided by the battery per unit weight or unit volume.

Specifically, the energy of a battery can be understood as the electrical energy output by doing work under certain discharge conditions. There are two common ways to express specific energy, one is weight specific energy (Wh/kg) and the other is volume specific energy (Wh/L). Both of these expressions are used to describe the energy density of a battery, that is, the amount of electrical energy that can be output per unit mass or unit volume of the battery.

Due to some special characteristics of military batteries, the specific energy is usually limited to less than 90wh/kg.

"Master Zhang, please stand at the door and don't let anyone come to the backyard. I'm going to do an experiment." Xu Qiang said to Zhang Decai before starting the test. "Okay, I'll watch the door, you can do whatever you want!" Zhang Decai said, and directly moved a stool and sat at the door.

Although Zhang Decai was the person in charge of the scrap warehouse and Xu Qiang's immediate superior, he understood that Xu Qiang was a "favorite" in front of the factory director, and Liu Biao had previously instructed him to provide assistance to Xu Qiang, so as long as Xu Qiang did not want to blow up the scrap warehouse, he would meet any other requests.

Holding the weighed sulfuric acid mixed solution, perchloric acid and iron electrodes, as well as multimeter beaker and other tools, Xu Qiang began the preparation work.

Place the two electrodes in a beaker. This beaker can generally withstand a high temperature of 1100°C, so there should be no problem doing this experiment.

Then use two wires to connect the two electrodes to the multimeter. After fixing them, Xu Qiang adjusted the meter. Next it was time to add the solution.

This step can be said to be dangerous. When the sulfuric acid solution comes into contact with the iron sheet, a distance reaction will occur, so Xu Qiang will keep as much distance as possible when pouring the solution.

"puff!"

Almost at the moment the sulfuric acid mixture was poured in, the iron sheet in the beaker reacted violently. A faint white mist rose up, and the crystalline salt on the surface of the perchloric acid electrode also dissolved rapidly at a speed visible to the naked eye.

At this time, Xu Qiang was staring at the changes in the data on the multimeter. When the value reached a peak, he silently took note of it.

The entire test was completed almost in an instant. Xu Qiang took out his notebook and after some calculations, an expression of relief finally appeared on his face.

"cough!"

At this moment, Xu Qiang suddenly heard a dry cough behind him. He turned around and was stunned.

"Hello, Director Liu!"

The person who came was Liu Biao, and Zhang Decai was following behind him.

"What are you doing, kid?" Liu Biao asked with a frown as he looked at the white steam rising from the beaker.

"I am doing an experiment on the battery power, and it is now completed," said Xu Qiang.

"What's the result? Was it successful?" Liu Biao's eyes suddenly lit up when he heard this and he asked Xu Qiang.

"Not yet... This thing is not that easy. It needs to be tested repeatedly many times." Xu Qiang curled his lips and continued, "In addition, I have provided Chief Engineer Li with the drawings of the customized acid bottle. We have to wait for the samples from Shanghai to be delivered before we can proceed to the next step of research and development."

In fact, if this experiment was successful, Xu Qiang's military battery project would be halfway successful. Only the acid bottle filling part remained, but that no longer involved chemical processes and was entirely the business of the custom manufacturer.

However, when facing his leader, Xu Qiang absolutely cannot report the good news in advance. On the one hand, the project has not been completed yet. On the other hand, if the project is completed, Xu Qiang may not have the capital to put forward conditions. So what he has to do now is to whet Liu Biao's appetite so as to gain more resources and convenience.

"Uh..." Hearing this, a hint of disappointment flashed across Liu Biao's face.

"But I estimate that this project should be completed within two months," Xu Qiang added.

"It's not that you should be able to do it, but that you must do it!" Liu Biao said in a serious tone, and then said, "I have already publicized your military order in the factory. Do you know about this?"

"I know." Xu Qiang nodded.

"In fact, I didn't want to make your military order public, but after discussing it with Mr. Li, I decided to make it public..." Liu Biao paused, and then said, "This means that you have no way out now. Either the product is successful, or you will be punished by the factory. You must be mentally prepared for this..."

"Director Liu, since my military order has been made public, if the project is successful, it's okay for me to ask for more rewards, right?" Xu Qiang said.

"Of course, what reward do you want?" Seeing that Xu Qiang didn't seem nervous at all about the public military order, Liu Biao was somewhat surprised, so he asked.

"There will be no problem in getting a permanent job, right? The other thing is to arrange a special chemistry laboratory for me and buy some chemistry experimental equipment. As I told you before, these equipment will cost at least 100,000 yuan." Xu Qiang said with a smile.

Last time, Xu Qiang had proposed this request to Liu Biao. However, for Xu Qiang, only when advanced equipment was in place could he help the factory develop more advanced military products. So even though he knew that Liu Biao was a bit stingy, he still wanted to achieve his goal...
