"Master, this thing is a battery? Do you want to try connecting a light bulb to it? "
In a laboratory in the workshop.
When Faubert heard Li Zexuan say that the square thing in front of him was the first lead-acid battery in the world, he was shocked.
Li Zexuan nodded and said, "Of course, we have to try it! Uncle Fu, can I trouble you to get someone to bring a low-powered light bulb and some wires? "
When the lead-acid battery was first made, it did not need to be charged. It could be used directly because it was full of chemical energy. The so-called charging was to use the external electrical energy to regenerate the active material (lead sulfate) and store the electrical energy as chemical energy. Now that the battery was not discharging, there was no active material (lead sulfate) in the electrolyte. Naturally, there was no need to charge it!
"Okay! Master, wait a moment! "
Faubert smiled and left.
After a while, Faubert brought Song Xiaosi with a few light bulbs of different sizes and some copper wires. Li Zexuan removed the rubber on both ends of the wires. One end of the two wires was connected to the positive electrode of the battery, and the other end was connected to the positive and negative screw at the end of the light bulb. The moment the wires touched the end of the light bulb, the light bulb suddenly lit up!
"It lit up! It really lit up! It seems that the power of this lead-acid battery is stronger than the voltaic battery that you made before. This kind of light bulb can't be lit up by the voltaic battery! "
Faubert could not help but exclaim.
When it came to electricity, he could be considered as half an expert. Although he did not speak as professionally as Wang Ji, he understood the general idea!
"Heh! Yamachō, your lead-acid battery is really a success? My goodness, it can light up such a big light bulb. What is the output voltage of this lead-acid battery? "
Speaking of the devil, Wang Ji came out of the steel mill to take a look. He did not expect to see this scene as soon as he stepped into the laboratory. He could not help but ask in surprise.
Compared to Faubert, his question was obviously more professional!
Li Zexuan smiled and replied, "In this lead-acid battery, the voltage of each battery pack is about two volts. There are a total of six battery packs connected in series, and the voltage is about twelve volts. Naturally, the voltage is higher than the voltaic battery! Moreover, the continuous discharge capacity of this lead-acid battery was much stronger than that of a voltaic battery. With just this small light bulb, it wouldn't be a problem to light it up for 24 hours! Moreover, after the battery is used up, it can be recharged. After recharging, it can be used again! "
"Twelve volts? Keep the lights on for twenty-four hours? Can it be recharged after the battery runs out? "
Wang Ji was really shocked this time. He had used the voltaic batteries made by Li Zexuan before. Each voltaic battery only had about one volt of power, and it did not last long. If it was used to send and receive telegrams, it would run out of power in less than four hours!
Today's batteries, whether it was the output voltage or the ability to supply power for a long time, were far superior to the voltaic batteries. Moreover, the lead batteries could be recharged after they ran out of power, unlike the voltaic batteries which could only be thrown away after they ran out of power!
These unparalleled and inconceivable advantages made Wang Ji doubt his life a little!
"Yamachō, can you tell me the principle behind the charging and discharging of this lead-acid battery? This is the first time I've heard of a battery that can be recharged and recycled! "
After a while, Wang Ji recovered from his shock and looked at Li Zexuan expectantly.
Although it was already late, Li Zexuan knew that if he didn't explain the principle of charging and discharging lead-acid batteries to Wang Ji today, with this old man's temperament, he probably wouldn't be able to sleep tonight. In order to let the old man sleep well, Li Zexuan took out a piece of blank rice paper and wrote a chemical equation on it with a pencil as he began to explain:
"Mr. Wang, the material of the anode plate of this battery is lead dioxide, and the material of the cathode plate is lead. The electrolyte is prepared dilute sulfuric acid. There is a separator in the electrolyte to separate the electrolyte between the two electrodes and prevent the electrodes from shorting. When discharging electricity, the lead in the cathode plate reacts with the electrolyte to produce lead sulfate and water, releasing electricity. When charging the battery, under the action of external electricity, the lead sulfate reacts with the acid in the water to produce lead fluff and sulfuric acid, storing electricity … "
It took nearly half an hour to explain the charging and discharging principle of the battery to Wang Ji. During this time, Wang Ji raised a lot of technical questions, and Li Zexuan patiently answered them one by one. When everything was finished, it was already close to midnight!
"Yamachō, this lead-acid battery is really amazing, especially now that we have a hydropower station in Lantian County and Yanhuang College is connected to electricity, the role of this battery is even more obvious! After using up the electricity outside, it can be recharged with electricity from the hydropower station. Perfect! It's simply perfect! This old man is truly in awe of Mountain Chieftain's ingenuity! "
Wang Ji's eyes became brighter and brighter, and the gaze he looked at the lead-acid battery became more and more passionate. At this time, he suddenly remembered that he came here to find Li Zexuan for business, and quickly said, "Oh! Yamachō! The steel mill has already produced vanadium steel. This old man has done some experiments in private, and this vanadium steel is indeed much harder than ordinary steel. Yamachō, do you want to go take a look? "
Li Zexuan looked at the dark sky outside and couldn't help but ask, "Faubert, what time is it now?"
After transmigrating for so long, Li Zexuan still couldn't accurately determine the time. He estimated that he wouldn't be able to practice this skill in his lifetime. He could only wait until the invention of the watch, and then he would be able to completely "control time".
"Young Master, it should be midnight now!"
Faubert was silent for a moment, and then replied.
Midnight, which was nine o 'clock in the evening!
He actually worked from one or two o 'clock in the afternoon until nine o' clock in the evening, and he didn't even eat dinner in the middle!
Not only did he not eat dinner, but Faubert and Wang Ji also didn't eat!
"I'm not looking! I'm not looking! I'll look tomorrow! It's not early today, Mr. Wang, Faubert, this man is iron, rice is steel, everyone go back early to eat and rest! Our bodies are the capital for our inventions! "
At this time, Wang Ji, a workaholic, actually wanted to drag him to the steel mill to "work". Li Zexuan would never do that, even if he was beaten to death. He still had a wife and children at home. Oh, he didn't have any children yet, but he couldn't go back too late and make his wife worry, right? Therefore, he waved his hand and said to Wang Ji and Faubert.
"Hehe! Young Master is right, then this old man will go first! I'm old, I can't handle it! "
Faubert said with a smile.
Wang Ji was unwilling, but seeing that Faubert had said so, he couldn't disagree, so he could only pack up and leave the workshop with Li Zexuan. They went up Yun Mountain!
He was now living in the academy's teachers' dormitory, not Yun Mountain Residence, because his title had not reached the level of a professor!
However, based on Wang Ji's enthusiasm in chemistry and his recent results, it was only a matter of time before he became a professor in the academy!
"Husband, you're back? You haven't eaten yet, right? I'll heat up the food for you now! "
When they returned to the residence, Han Yuxi heard the movement at the door, and quickly came out of the house to welcome them.
Obviously, she hadn't slept, waiting for Li Zexuan to come back!
"Wife, why aren't you asleep at this time? It's all my fault, I was so busy in the workshop that I forgot the time and forgot to send someone to tell you! "
Li Zexuan said apologetically.
"Husband, don't say that!"
Han Yuxi hurriedly said, "You're busy in the workshop, and it's not midnight yet, so I'm not sleepy! Alright, let's not talk about it, I'm going to warm up with my husband! "
Li Zexuan hugged Han Yuxi and kissed her gently on the forehead. He said, "My wife is so considerate, I'll give you something good in a few days!"
Han Yuxi asked curiously, "What good thing?"
Li Zexuan smiled mysteriously and said, "I'll keep it a secret for now, but it'll definitely be a big surprise!"
.....
The next day.
Li Zexuan went to the workshop again after breakfast.
Speaking of which, he was now sitting in the position of Marquis. Logically speaking, he didn't have to work so hard. Even if he ate, drank, and played every day, with the huge foundation he had built previously, he could guarantee that he wouldn't have to worry about food and clothing for the rest of his life!
When he first transmigrated, Li Zexuan thought that as long as he could be a Marquis, he would spend his life waiting for death. However, sometimes, only when you really sat in that position would you understand your responsibilities!
Li Zexuan was now the Yamachō of Yanhuang College, the real master of tens of thousands of people in Lantian County, and the helmsman of the entire "Yanhuang Corporation". Behind him, countless students were learning from him, improving and growing; countless people were relying on him to eat; countless craftsmen were using his innovative technology and tools to liberate productivity; and countless merchants were relying on him to become rich and realize their own value!
He couldn't stop!
His position as Marquis was created by the invention of engineering. Therefore, he had the obligation to bring engineering to greater heights in this era. Moreover, to him, creating modern things in the ancient times was where his joy lay. He wanted and was willing to make this Tang Dynasty even more advanced and powerful!
When he arrived at the steel mill, Wang Ji was already waiting there. These two days were the weekend of the academy, so Old Wang didn't have any classes at the academy. He could also devote himself to "scientific research"!
"Yamachō, look! This is vanadium steel! This is vanadium steel that was refined according to the three different vanadium ratios that Yamachō provided! "
Wang Ji pointed at the pile of steel on the ground and said to Li Zexuan.
"Mm! Let's use this vanadium steel to make swords and armor first, then we'll test it out! "
Li Zexuan nodded and said.
The ratio of vanadium in vanadium steel was generally not high, around 0.025% to 0.059%. Different ratios of vanadium would result in different hardness of vanadium steel. As for which ratio was the most suitable for making swords and sabers, and which was the most suitable for making armor, all of these would need to be tested!
In addition, by adding a certain ratio of vanadium to the steel, one could make rebar that could be used as the framework of reinforced concrete!
Compared to ordinary steel, rebar's hardness and toughness were both very good. It was suitable to be used as the framework of reinforced concrete in large projects. It could significantly increase the strength of the project and increase the level of earthquake resistance!
"Alright! Then, Yamachō, please wait a moment! "
Wang Ji nodded in response.
There were all kinds of craftsmen in the workshop, and naturally, there was no lack of skilled blacksmiths. Wang Ji sent the vanadium steel to the blacksmith's workshop and instructed the blacksmiths to use the three different ratios of vanadium steel to make three sets of swords and armor. The blacksmith's workshop immediately began to bustle with activity!
"Yamachō, do you think that the swords and sabers made of vanadium steel will be so sharp that they can cut through metal like mud? As for armor, will the armor made of vanadium steel be stronger than the armor used by Tang soldiers? "
The temperature in the blacksmith's workshop was too high. Wang Ji was old and could not withstand the heat. After he finished instructing the craftsmen, he left the workshop to find Li Zexuan and asked.
Li Zexuan smiled and nodded. "Although I wouldn't dare to say that they can cut through metal like mud, if ordinary iron swords and sabers were to meet vanadium steel swords and sabers, they would definitely suffer great damage! As for armor, I have even more confidence in it. Armor made of vanadium steel is definitely superior under the same conditions! "
Vanadium alloying could greatly increase the strength of carbon steel, especially under the conditions of quenching and tempering. The improvement in performance was even more obvious. In his previous life, a fortuitous event led to the use of vanadium in automobile steel. It was said that when Henry Ford I was watching a race, a French car was crashed. When he examined the wreckage of the car, he found that the damage of a crankshaft produced in Sweden was much smaller than expected.
After testing, it was found that the steel contained vanadium. Therefore, Ford used vanadium alloyed steel to make the key parts of the Ford car to better resist the vibration and fatigue of the road. He once famously said, "If there was no vanadium, there would be no cars."
Because a very small amount of vanadium could give the steel excellent performance, people at that time had a very vivid evaluation of the role of vanadium in steel — vanadium was the vitamin in steel.
Thus, when vanadium steel was used to make armor, although it was not absolutely invulnerable, it was definitely able to resist most cold weapons!
"This is amazing. Who would have thought that just adding a little vanadium to steel could greatly improve the performance of the steel? This is really incredible!"
Wang Ji muttered to himself.
"Hehe! Mr. Wang, wait here. I'll go draw a blueprint. I'm planning to make something new! "
Li Zexuan knew that forging the swords and armor was not something that could be done in a short period of time. It would take at least half a day, so he said to Wang Ji.
When Wang Ji heard this, his eyes lit up. "Oh? Yamachō has a good idea again? I wonder what new thing you want to make this time? "
"Hehe! Mr. Wang, you will know in a while! When the armor is done, remember to send someone to inform me! "
Li Zexuan did not say anything, so Wang Ji smiled.
When Wang Ji saw this, he did not ask further.
Li Zexuan returned to his office in the workshop and began to draw the blueprint. At noon, Song Xiaosi brought him lunch. He finished it quickly and continued to draw the blueprint. There was a thick stack of blueprints on his desk. It was obvious that the thing he was going to make this time was not simple!
"Mountain leader, the swords and armors are ready! Take a look! "
At around five in the afternoon, Wang Ji came to Li Zexuan's office with two manservants, carrying three pairs of swords and armors, and said excitedly.
"Oh? How is the effect? Mr. Wang, have you tried it? "
Li Zexuan put down his pen, stood up and asked with a smile.
"I've tried it! I've tried it! This sword was just like what the mountain leader had said. It could easily cut through ordinary swords and sabers made of iron! It's really sharp! As for the armor, even arrows can't penetrate it. It's really tough! "
Wang Ji said ecstatically.
