"Young master, is this a battery? Why don't you take a light bulb and give it a try? ”

Workshop, in a laboratory.

When Fu Bo heard Li Zexuan say that the boxy thing in front of him was the first lead-acid battery in the world, he was slightly shocked and couldn't help but say.

Li Zexuan nodded and said, "Of course you have to try!" Fauber, please have someone bring over a lightbulb with less power and some wires! ”

The lead-acid battery does not need to be charged when it is just done, it can be used directly, because it is full of chemical energy, the so-called charging is to use external electrical energy to regenerate the internal active substance (lead sulfate), and store the electrical energy as chemical energy.

"Okay! Young Master, wait a minute! ”

Fauber smiled and left.

After a while, Fu Bo took Song Xiaosi to bring a few bulbs of different sizes and some copper wires, Li Zexuan pulled away the rubber at both ends of the wire, one end of the two wires was connected to the positive pole of the battery, and the other end was connected to the positive and negative screws at the end of the bulb.

"It's lit! It's really lit up! It seems that the power supply capacity of this lead-acid battery should be more powerful than the volcanic battery you made earlier, young master, because this kind of bulb volcanic battery can't light up at all! ”

Seeing this, Fauber couldn't help but exclaim.

In terms of electricity, he is also half knowledgeable, although he is not as professional as Wang Ji, but he understands the general meaning!

"Huh! Shanchang, your lead-acid battery has really been successful? Obediently, it can light such a large light bulb, what is the output voltage of this lead-acid battery? ”

Said Cao Cao Cao arrived, after Wang Ji came out of the steel mill, he planned to come over to have a look, but he didn't expect to see this scene as soon as he stepped into the laboratory, and he couldn't help but ask in surprise.

Compared to Fauber, his questions are obviously more professional!

Li Zexuan replied with a smile: "In this lead-acid battery, the voltage of one battery pack is about two volts, and there are a total of six battery packs in series, and the voltage is about twelve volts, which is naturally greater than the voltage of the voltaic battery!" And the continuous discharge ability of this lead-acid battery is also much stronger than that of voltaic batteries, just this small light bulb, it can light up for twelve hours without a problem! And when the power is used up, it can be charged, and it can continue to be used after charging! ”

"Twelve volts? Keep the lights on for twelve hours? Can you still charge it when you run out of power? ”

Wang Ji was really shocked now, he had also used the voltaic batteries made by Li Zexuan before, the power of each voltaic battery was only about one volt, not to mention, the power was not long-lasting, if it was used to continue to receive and receive telegrams, it would basically run out of power in less than two hours!

Today's batteries, whether it is the output voltage or the ability to provide lasting power supply, are far better than voltaic batteries, and lead-acid batteries can be recharged after the power is used up, unlike voltaic batteries, which can only be thrown away after the power is used up!

These incomparable and incredible superiority simply made Wang Ji a little doubtful about life!

"Chief, can you tell Wang about the principle of charging and discharging this lead-acid battery? It's the first time I've heard that batteries can be charged and recycled~! ”

After a while, Wang Ji recovered from the shock, then looked at Li Zexuan expectantly and asked.

Although it is getting late now, Li Zexuan knows that if he doesn't explain the principle of charging and discharging the lead-acid battery to Wang Ji today, according to the old guy's temperament, it is estimated that he will not be able to sleep tonight, in order to let the old man sleep well, Li Zexuan took out a blank piece of rice paper, wrote the chemical equation on it with a pencil, and began to explain:

"Mr. Wang, the material of the anode plate of this battery is lead dioxide, the material of the cathode plate is lead, the electrolyte is prepared dilute sulfuric acid, and there is a separator plate in the electrolyte, which separates the electrolyte between the two poles to prevent the electrode from short circuiting. When discharged, the lead of the cathode plate reacts with the electrolyte to generate lead sulfate and water, which emits electrical energy; When charging, the battery reacts with the acid in the water under the action of external electrical energy, and generates velvety lead and sulfuric acid, which stores the electrical energy........"

It took nearly half an hour to explain the charging and discharging principle of the battery to Wang Ji clearly, during which Wang Ji raised many technical questions, and Li Zexuan patiently answered them one by one.

"Mountain Chief, this lead-acid battery is really magical, especially now that we have a hydropower station in Lantian County and Yanhuang Academy is connected to electricity, the role of this battery is even more obvious! After running out of electricity outside, you can take back the electricity from the hydropower station to recharge, perfect! It's perfect! For the whimsy of the mountain chief, the old man really admires the five-body throw! ”

Wang Ji's eyes became brighter and brighter, and his gaze at the lead-acid battery became hotter and hotter, at this time, he suddenly remembered that he had something serious to do when he came here to find Li Zexuan, and hurriedly said: "Oh! Mountain Chief! Over there in the steel mill, vanadium steel has been trained, the old man has done experiments in private, this vanadium steel is indeed much harder than ordinary steel, do you want to take a look? ”

Li Zexuan looked at the dark sky outside, and couldn't help asking, "Fu Bo, what time is it?" ”

After so long, Li Zexuan still does not have the ability to accurately judge the time anytime and anywhere, he estimates that he will not be able to exercise this skill in his lifetime, and he can only completely "control time" after the invention of the watch later.

"Young Master, it should be just time to arrive in Hai!"

Fauber was silent for a moment, then replied.

It's nine o'clock in the evening!

He worked in the workshop from one or two o'clock in the afternoon until nine o'clock in the evening, and he didn't even eat dinner in between!

Not only did he not eat dinner, but Fu Bo and Wang Ji also didn't eat!

"Don't look at it! Don't look at it! See you tomorrow! It's not early today, Mr. Wang, Fu Bo, this person is iron, rice is steel, let's go back to eat and rest early! The body is the capital that we invent and create new things! ”

It's all at this point in time, Wang Ji, a workaholic, still wants to pull him to the steel mill to "work", Li Zexuan won't do this if he is killed, he still has a wife and children at home, oh, there are no children yet, but it can't go back too late to worry his daughter-in-law, right? Yes, he waved his hand and said to Wang Ji and Fu Bo.

"Huh! What the young master said is that the old man will go first! I'm old, I can't bear it! ”

Fauber said with a smile.

Wang Ji was unwilling, but seeing that Fu Bo also said so, he didn't want to disagree, so he had to clean up, go out of the workshop with Li Zexuan, and go to Yunshan!

He now lives in the teacher's dormitory of the academy, not the Yunshan Annex, because his title has not yet reached the level of professor!

However, judging from Wang Ji's research in chemistry and his recent achievements, it is probably only a matter of time before he is rated as a professor in the college!

"Xianggong, are you back? Haven't eaten yet, have you? The concubine is going to warm up the food for you! ”

Back in the courtyard, Han Yuxi heard the movement at the door, and hurriedly greeted him from the house and said.

Obviously, she hasn't slept all this time waiting for Li Zexuan to come back!

"Lady, why haven't you slept so late? It's all my husband's fault, I forgot the time when I was busy in the workshop, and I forgot to send someone to tell you! ”

Li Zexuan said slightly apologetically.

"Don't say that!"

Han Yuxi hurriedly said: "You are busy in the workshop, and besides, when you are not here yet, the concubine is not sleepy!" Okay, let's not talk about it, the concubine went to have a hot relationship with the princess~! ”

Li Zexuan took Han Yuxi, kissed him lightly on the forehead, and said: "The lady is considerate, and she will give her husband something as good as the lady in a few days~!" ”

Han Yuxi was curious: "What kind of good thing?" ”

Li Zexuan smiled mysteriously and said, "Keep it secret for the time being, but it must be a big surprise!" ”

.........................

The next day.

Li Zexuan had breakfast and went to the workshop again.

It is said that he has now sat in the position of the marquis, and it is reasonable that he does not have to work so hard, even if he eats, drinks and has fun every day, with the great foundation he created before, he can ensure that he has no worries about food and clothing for a lifetime!

When he first crossed over, Li Zexuan thought so, as long as he could be a marquis, he would eat and wait for death for the rest of his life, but sometimes, only when you really sit in that position will you understand your responsibility!

Li Zexuan is now the head of Yanhuang Academy, the real master of tens of thousands of people in Lantian County, and the helmsman of the entire "Yanhuang Group". Hundreds of people were feeding on him; There are also countless craftsmen who are using his innovative technical tools to liberate the productive forces; There are countless businessmen who rely on him to get rich and realize their own value!

He can't stop!

He is a prince who relies on engineering inventions and creations, so he has the obligation to carry forward engineering in this era, and for himself, creating some modern things in ancient times is also his fun, he thinks, and is willing to make this Tang Dynasty with him, more advanced and more powerful!

Coming to the steel mill of the workshop, Wang Ji was already waiting here, these two days were weekends and weekends in the academy, so Lao Wang had no classes in the academy, and he could devote himself to "scientific research"!

"Chief, look! This is vanadium steel! This is a vanadium steel made according to the three different vanadium-doped ratios provided by Shanchang! ”

Wang Ji pointed to the pile of steel on the ground and said to Li Zexuan.

"Hmmm! Use these vanadium steels to craft swords and armor first, and then try the results! ”

Li Zexuan nodded and said.

The proportion of vanadium in vanadium steel is generally not high, about 0.025%-0.059%, different vanadium content, the hardness of vanadium steel made of it is also different, which ratio is most suitable for swords, which is most suitable for armor, this needs to be tested!

In addition, by adding a certain percentage of vanadium to the steel, it is possible to create rebar for the skeleton of reinforced concrete building elements!

Compared with ordinary steel, the solidity and toughness of rebar are very good, and it is suitable for use as a steel skeleton in large engineering projects, which can obviously improve the engineering strength and seismic grade!

"Good! Wait a minute! ”

Wang Ji nodded in response.

There are all kinds of craftsmen in the workshop, and naturally there is no shortage of skilled blacksmiths, Wang Ji sent these vanadium steels to the blacksmith workshop, and instructed the blacksmith to use these three proportions of vanadium steel to create three sets of swords and armor respectively, and the blacksmith workshop immediately began to get busy!

"Mountain Chief, do you say that this sword made of vanadium steel can really be sharp and sharp? And the armor, the armor made of vanadium steel, will it definitely be stronger than the armor used by my Tang soldiers? ”

The temperature in the blacksmith workshop was too high, Wang Ji was old, and he couldn't resist it, so after he finished entrusting the craftsman, he went out of the workshop, found Li Zexuan, and asked.

Li Zexuan smiled slightly, nodded and said, "Although I don't dare to say that iron is sharpened like clay, if it is an ordinary iron sword, when it encounters a sword forged from vanadium steel, it will definitely suffer a lot of damage!" As for the armor, I am even more confident in this, the armor made of vanadium steel, under the same conditions, its superiority is absolutely undoubted! ”

Vanadium alloying can greatly improve the strength of carbon steel, especially under the process conditions of quenching and tempering, the performance improvement is more obvious. In a past life, a fortuitous event prompted the use of vanadium in automotive steels. Legend has it that Henry Ford I, while watching a motor race, was wrecked in a French car, and while examining the wreckage of the car, he found that a Crankshaft made in Sweden was much less damaged than expected.

After testing, it was found that the steel contained vanadium. So Ford uses vanadium alloyed steel to make the key components of Ford vehicles to better resist vibration and fatigue on the road. He once famously said, "If there were no vanadium, there would be no cars." ”

Because 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 a vitamin in steel.

It can be seen that using vanadium steel to make armor is not to mention absolute invulnerability, but it can definitely resist most cold weapon damage!

"It's amazing, who would have thought that just adding a little vanadium to the steel can improve the performance of the steel so dramatically, it's really incredible!"

Wang Ji muttered to himself.

"Huh! Mr. Wang, you wait for a while, I'm going to draw a drawing, I'm going to make something new! ”

Li Zexuan knew that building swords and armor could not be completed in a while, and it would take at least half a day, so he said to Wang Ji.

When Wang Ji heard this, his eyes lit up and said, "Oh? The mountain chief has a good idea again? I wonder what new things are going to be built this time? ”

"Huh! You'll know in a moment, Mr. Wang! After the sword armor here is built, remember to have someone come and inform me! ”

Li Zexuan didn't say it explicitly, and said with a slight smile.

Seeing this, Wang Ji couldn't ask questions, so he could only answer.

Li Zexuan returned to his office in the workshop and began to draw drawings, and at noon Song Xiaosi brought him a meal, which he ate by dividing it by two, and then continued to draw drawings. There was already a thick pile of drawings on the entire desk, which showed that what he wanted to build this time was not simple!

"Mountain Chief, the sword and armor are ready! Check it out! ”

Around Shen Shi, Wang Ji took two workshop boys, brought three pairs of swords and armor, came to Li Zexuan's office, and said excitedly.

"Oh~? The result? Has Mr. Wang ever tried it? ”

Li Zexuan put down his pen, stood up, and asked with a smile.

"Tried it! Tried it! This sword is really as the mountain chief said, ordinary iron swords can be easily cut by it! It's so sharp! As for this armor, it can't be pierced by a bow or arrow, it can't be stronger! ”

Wang Ji said ecstatically.
