"Master, is this a battery? Do you want to connect a light bulb to it and try it?"
Workshop, inside a laboratory.
When Uncle Fu heard Li Zexuan say that the boxy thing in front of him was the world's first lead-acid battery, he was slightly shocked and couldn't help but say.
Li Zexuan nodded and said: "Of course I have to try it! Uncle Fu, could you please ask someone to bring a less powerful light bulb and some wires?"
Lead-acid batteries do not need to be charged when they are first made. They can be used directly because they are full of chemical energy. The so-called charging is to use external electrical energy to regenerate the internal active material (lead sulfate) and store the electrical energy as chemical energy. , the battery is not discharging at this time, and there is no active material (lead sulfate) in the electrolyte, so naturally there is no need to charge!
"Okay! Master, please wait a moment!"
Fu Bo smiled and left.
After a while, Uncle Fu and Song Xiaosi brought several light bulbs of different sizes and some copper wires. Li Zexuan removed the rubber on both ends of the wires, and connected one end of the two wires to the positive pole of the battery. The other end is connected to the positive and negative screws at the end of the bulb respectively. The moment the wire touches the end of the lamp, the lamp suddenly lights up!
"It's on! It's really on! It seems that the power supply capacity of this lead-acid battery should be more powerful than the voltaic battery you made before, Master, because this kind of light bulb voltaic battery cannot light up at all!"
When Uncle Fu saw this, he couldn't help but exclaimed.
When it comes to electricity, he can be considered semi-savvy. Although he doesn't speak as professionally as Wang Ji, he understands the general meaning!
"Haha! Chief Shan, did you really make your lead-acid battery successfully? Darling, it can actually light up such a big light bulb. What is the output voltage of this lead-acid battery?"
When Cao Cao arrived, Wang Ji planned to come over and take a look after he came out of the steel mill. Unexpectedly, he saw this scene as soon as he stepped into the laboratory. He couldn't help but asked in surprise.
Compared to Forbes, his questions were obviously more professional!
Li Zexuan smiled and replied: "In this lead-acid battery, the voltage of one battery pack is about two volts. There are six battery packs connected in series, and the voltage is about twelve volts. Naturally, the voltage is higher than that of a voltaic battery! And! The continuous discharge capacity of this lead-acid battery is much stronger than that of a voltaic battery. It can light up this small light bulb for twelve hours without any problem! And after the power is used up, it can be charged. Then it can be used again!”
"The voltage is twelve volts? Keep the light on for twelve hours? Can it be recharged after the power is used up?"
Wang Ji was really shocked. He had used the voltaic batteries made by Li Zexuan before. The power of each voltaic battery was only about one volt. The power was not long-lasting. If it was used to continuously send and receive telegrams, it would basically not last long. The battery will run out in two hours!
Today's batteries are far superior to voltaic batteries in terms of output voltage and long-lasting power supply capabilities. Moreover, lead-acid batteries can be recharged after they are used up. Unlike voltaic batteries, they can only be thrown away after they are used up. Lost!
These incomparable and incredible advantages simply made Wang Ji doubt his life!
"Shan Zhang, can you tell Wang the principle of charging and discharging this lead-acid battery? This is the first time I have heard that batteries can be recharged and recycled~!"
After a moment, Wang Ji recovered from the shock, then looked at Li Zexuan expectantly and asked.
Although it was getting late now, Li Zexuan knew that if he didn't explain the principles of charging and discharging lead-acid batteries to Wang Ji clearly today, according to the old guy's temperament, he probably wouldn't be able to sleep tonight. In order to let the old man have a good sleep, Li Zexuan took out a blank rice paper, wrote a chemical equation on it with a pencil, and began to explain:
"Mr. Wang, the anode plate of this battery is made of lead dioxide, the cathode plate is made of lead, and the electrolyte is prepared dilute sulfuric acid. There is a separator in the electrolyte to separate the electrolyte between the two poles and prevent The electrode is short-circuited. When discharging, the lead on the cathode plate reacts with the electrolyte to generate lead sulfate and water, releasing electrical energy; when charging, under the action of external electric energy, the lead sulfate reacts with the acid in the water to generate velvety lead and sulfuric acid. , store electrical energy..."
It took nearly half a quarter of an hour to clearly explain the charging and discharging principles of the battery to Wang Ji. During this period, Wang Ji raised many technical questions, and Li Zexuan patiently answered them one by one. After everything was completed, it was already approaching Hai hour. !
"Shan Zhang, this lead-acid battery is really magical. Especially now that we have a hydropower station in Lantian County and Yanhuang Academy has been connected to electricity, the role of this battery has become even more obvious! After you use up the electricity outside, you can take it back and use it again. The electricity generated by the hydropower station is used for charging. It’s perfect! It’s absolutely perfect! I’m really impressed by the mountain leader’s fantastic idea!”
Wang Ji's eyes were getting brighter and brighter, and the gaze he was looking at the lead-acid battery was getting hotter and hotter. At this moment, he suddenly remembered that he came here to see Li Zexuan for business, and he quickly said: "Oh! Chief! Steelmaking Over at the factory, vanadium steel has been produced. I have done experiments privately and it turns out that this vanadium steel is indeed much harder than ordinary steel. Chief, do you want to go and have a look?"
Li Zexuan looked at the pitch-black sky outside and couldn't help but ask: "Uncle Fu, what time is it now?"
After traveling through time for so long, Li Zexuan still cannot accurately judge the time anytime and anywhere. He estimates that he will not be able to develop this skill in his lifetime. He can only "control time" after the invention of a watch later.
"Master, it should have just arrived at Haishi now!"
Fu Bo was silent for a moment and replied.
Haishi, that is, nine o'clock in the evening!
He actually worked in the workshop from one or two o'clock in the afternoon until nine o'clock in the evening, without even having dinner!
Not only did he not have dinner, neither did Uncle Fu or Wang Ji!
"Don't watch it! Don't watch it! Let's watch it tomorrow! It's getting late today. Mr. Wang and Uncle Fu, these people are like iron and rice is like steel. Let's go back early to eat and rest! The body is where we create new things. capital!"
At this point in time, Wang Ji, a workaholic, still wants to drag him to "work" in the steel mill. Li Zexuan would not do this if he was beaten to death. He still has a wife and children at home. Oh, he has no children yet, but Then you can’t go back too late and worry your wife, right? Therefore, he waved his hand and said to Wang Ji and Uncle Fu.
"Haha! What the young master said is true, then I will take the first step! I am too old to bear it!"
Fu Bo said with a smile.
Wang Ji was unwilling to give in, but seeing that Uncle Fu also said the same thing, he had no choice but to disagree, so he had to pack up and follow Li Zexuan out of the workshop and go to Yunshan!
He is currently living in the teachers' dormitory of the academy, not Yunshan Villa, because his professional title has not yet reached the professor level!
However, judging from Wang Ji's enthusiasm for studying chemistry and his recent achievements, it is probably only a matter of time before he becomes a professor in the academy!
"Ms. sir, are you back? You haven't eaten yet? I'm going to heat up the food for you right now!"
Back in the other courtyard, Han Yuxi heard the movement at the door and hurriedly came out of the house and said.
Obviously, she hasn't slept waiting for Li Zexuan to come back!
"Madam, why haven't you slept at this late hour? It's all my fault, husband. He was so busy in the workshop that he forgot about time. He also forgot to send someone to tell you!"
Li Zexuan said slightly apologetically.
"Sir, don't say that!"
Han Yuxi said hurriedly: "You are busy with big things in the workshop. Besides, it's not yet midnight, so I'm not sleepy! Okay, let's not talk anymore. I'm going to have sex with my husband~!"
Li Zexuan took Han Yuxi in his arms, kissed him gently on the forehead, and said, "My wife is so considerate, I will give my husband something as good as my wife in a few days~!"
Han Yuxi asked curiously: "What good thing?"
Li Zexuan smiled mysteriously and said, "We'll keep it a secret for now, but it will definitely be a big surprise!"
.............................
the next day.
After Li Zexuan had breakfast, he went to the workshop again.
It is said that he has now reached the position of a prince. Logically speaking, there is no need to work so hard. Even if he eats, drinks and has fun every day, relying on the huge foundation he has created previously, he can guarantee that he will have enough food and clothing for the rest of his life!
This is what Li Zexuan thought when he first traveled through time. As long as he could be a prince, he would live his whole life and wait until death. But sometimes, only when you really sit in that position can you understand your responsibilities. !
Li Zexuan is now the head of Yanhuang Academy, the true master of tens of thousands of people in Lantian County, and the helmsman of the entire "Yanhuang Group". Behind him, there are countless students who are learning from him and making progress; there are countless people who are relying on him. He eats with him; there are countless craftsmen who are using his innovative technical tools to liberate productivity; and there are countless businessmen who are relying on him to get rich and realize their own value!
He can't stop!
As a prince, he relied on engineering inventions and creations, so he had the obligation to carry forward engineering in this era. Moreover, for him, creating some modern things in ancient times was also his fun. He thought, And he is willing to make the Tang Dynasty with him more advanced and powerful!
When they arrived at the steelmaking plant of the workshop, Wang Ji was already waiting here. These two days were the weekends of the academy, so Lao Wang had no classes in the academy and could devote himself to "scientific research"!
"Shan Chief, look! This is vanadium steel! This is vanadium steel refined according to the three different vanadium doping ratios provided by you, Chief Shan!"
Wang Ji pointed to the steel piled on the ground and said to Li Zexuan.
"Well! Use these vanadium steels to make swords and armor first, and then try the effects!"
Li Zexuan nodded and said.
The vanadium-containing proportion in vanadium steel is generally not high, about 0.025%-0.059%. Different vanadium-containing proportions will result in different hardnesses of the vanadium steel refined. Which proportion is most suitable for making swords and which one is most suitable? Making armor requires testing!
In addition, adding a certain proportion of vanadium to steel can create rebar used for the skeleton of reinforced concrete building components!
Compared with ordinary steel, rebar has very good solidity and toughness. It is suitable to be used as the steel frame in large engineering projects. It can significantly improve the engineering strength and earthquake resistance level!
"Okay! Wait a minute, Commander!"
Wang Ji nodded in response.
There are all kinds of craftsmen in the workshop, and there is naturally no shortage of skilled blacksmiths. Wang Ji sent these vanadium steels to the blacksmith workshop and ordered the blacksmith to use these three proportions of vanadium steel to make three sets of swords and armors. The blacksmith workshop It immediately started to get busy!
"Captain, do you think this sword made of vanadium steel can really be as sharp as iron and cut iron like mud? And armor, armor made of vanadium steel will definitely be better than the armor used by my soldiers of the Tang Dynasty. Do you want it to be strong?”
The temperature in the blacksmith workshop was too high. Wang Ji was old and couldn't bear it. After giving instructions to the craftsmen, he left the workshop, found Li Zexuan, and asked.
Li Zexuan smiled slightly, nodded and said: "Although I dare not say that cutting iron is like clay, if it is an ordinary iron sword, it will definitely suffer a lot of damage when encountering a sword forged from vanadium steel! As for armor, I am more qualified for this. Be confident, the superiority of armor made of vanadium steel under the same conditions is absolutely unquestionable!"
Vanadium alloying can greatly increase the strength of carbon steel, especially under the process conditions of quenching and tempering, the performance improvement is more obvious. In a previous life, a chance event led to the use of vanadium in automotive steel. It is said that Henry Ford I was watching a racing competition when a French car was crashed. When examining the wreckage of the car, he found that the damage to a crankshaft produced in Sweden was much less than expected.
After testing, it was found that the steel contained vanadium. So Ford used vanadium alloyed steel to make key components of Ford vehicles to better resist road vibration and fatigue. He once famously said: "Without vanadium, there would be no cars."
Since a very small amount of vanadium can make steel obtain excellent properties, people at that time had a very vivid evaluation of the role of vanadium in steel - vanadium is the vitamin in steel.
It can be seen that armor made of vanadium steel is not absolutely invulnerable, but it can definitely resist most cold weapon damage!
"It's really amazing. Who would have thought that just adding a little vanadium to steel can greatly improve the performance of steel. It's really incredible!"
Wang Ji murmured to himself.
"Haha! Mr. Wang, please wait for a while. I'm going to draw a drawing. I plan to make something new!"
Li Zexuan knew that making swords and armors could not be completed in a short time. It would take at least half a day, so he told Wang Ji.
When Wang Ji heard this, his eyes lit up and he said, "Oh? The mountain chief has a good idea again? I wonder what new things are going to be built this time?"
"Haha! Mr. Wang, you will know in a moment! After the sword and armor are finished here, remember to have someone come over and notify me!"
Li Zexuan didn't say anything clearly, but the teacher smiled slightly.
When Wang Ji saw this, it was difficult to ask further questions, so he could only respond.
Li Zexuan returned to his office in the workshop and started drawing. At noon, Song Xiaosi brought him food. He ate it in three times, five divided by two, and then continued to draw. There is a thick stack of drawings piled on the entire desk. It can be seen that what he wants to build this time is not simple!
"Chief, the sword and armor are ready! Take a look!"
Around Shenshi, Wang Ji took two workshop boys, brought three pairs of swords and armors, came to Li Zexuan's office, and said excitedly.
"Oh~? How does it work? Has Mr. Wang 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 is really like what the mountain chief said. Ordinary iron swords can be easily cut off by it! It's so sharp! As for this armor, even bows and arrows can't penetrate it. It's so strong that it can't be penetrated. It couldn’t be stronger!”
Wang Ji said ecstatically.
