The materials used for the voltaic battery were: silver, zinc, salt, and blotting paper. As long as they were stacked together, they would form a battery that could generate electricity!
Then, were these materials available in ancient times? If you were traveling to the Ming Dynasty, congratulations, you would have all of these materials! You would be able to charge your phone directly. This was because zinc metal was first invented by China in the Ming Dynasty. At that time, it was called "Japanese lead." It was first extracted from silver ore imported from Japan.
Unfortunately, Li Zexuan had traveled to the Tang Dynasty, so he lacked one material: zinc.
But could a voltaic battery be made without zinc metal? Of course not. As long as there were two different metals, it could be made. The only difference was the voltage and current produced. The positive electrode material used in modern dry batteries was copper (gold or silver was better, but that was for the rich people's flashlights), and the negative electrode material was zinc.
Copper was also very easy to obtain in ancient times (unless you had the bad luck of eight lifetimes and traveled to the Stone Age). The negative electrode material could be aluminum or iron … Yes, iron, which was cheaper than copper!
In the room, ah, no, in the "laboratory," Li Zexuan was secretly glad that he had read "The Myth" in his previous life and had a lot of questions, so he had searched for a lot of information related to the manufacture of batteries on Baidu. Otherwise, he would not have thought of making a voltaic battery. He would have been a newborn calf that was not afraid of tigers, and would have definitely tried to make a generator.
Was he f * cking lucky?
Because in the Tang Dynasty, which did not have any industrial or electronic foundation, it was really difficult to make a generator with the theoretical knowledge he had learned from textbooks. Li Zexuan did not plan to make a generator at the moment. There were too many technical problems to solve, so he would do it in the future.
He took out a specially made rectangular clay jar. There were 50 independent compartments inside the jar. Because the voltage and current of a voltaic battery were definitely not enough, it needed to be connected in parallel to increase the current, and then connected in series to increase the voltage.
The crudest and simplest voltaic battery had a voltage of about one volt and a current of about ten to twenty milliamperes. If the voltaic batteries in each cubicle had a voltage of 1 volt and a current of 10 milliamperes, then 50 voltaic batteries would be connected in parallel to form a battery pack. Five of these battery packs would then be connected in series to form a power source with a voltage of 5 volts and a current of 500 milliamperes. Then, the problem of charging your mobile phone would be solved. (PS: If you plan to bring your mobile phone to ancient times, please remember this easiest way to charge your mobile phone.)
Of course, Li Zexuan was a soul transmigrator. When he transmigrated, he did not bring anything with him. The purpose of his battery was definitely not to charge his phone, but to power his communication tools.
He often lamented why he wasn't wearing a suit and couldn't bring a computer with him. He could have brought a mobile phone with him. When he was bored, he could play single-player Dou Dizhu or cut fruits.
However, there were also benefits of soul transmigration. At the very least, there were no obstacles when communicating with the people of the Tang Dynasty. This was because the official language of the Tang Dynasty was not Mandarin at all. It had a very thick accent. If it wasn't for soul transmigration, you would not be able to understand what others were saying.
Li Zexuan mixed a small basin of concentrated salt water and poured it into each cubicle one by one. When all 50 cubicles were filled, he inserted the two ends of the bent iron plates into the two adjacent cubicles. Then, he inserted the bent copper plates into the other side.
The copper plates were the positive electrodes of each voltaic battery, and the iron plates were the negative electrodes. When the iron plates and copper plates were inserted into the cubicles, it was equivalent to connecting all the positive electrodes together and the negative electrodes together. As a whole, the 50 small batteries were connected together in parallel, forming a battery pack with a voltage of about 1 volt and a current of about 500 milliamperes.
After completing the first battery pack, Li Zexuan took out a copper wire. It was a copper wire that was coated with lacquer. He used the copper wire to separate the positive and negative electrodes of the battery pack. Then, he covered the rectangular ceramic jar with a matching lid. Just like that, a simple battery was created. It was very convenient to use. He just needed to connect the positive and negative electrodes to the circuit. If he felt that the voltage was not enough, he could make a few more of these batteries and connect them in series.
"Young Master, it's time to eat!"
At this moment, Xiao Xi knocked on the door and shouted.
The servant girl took advantage of the time when Li Zexuan was doing experiments to ask San Bao to drive the carriage back to the Li Residence to get dinner. After all, the food outside could not be compared to the food in the Li Residence. In order to make Li Zexuan comfortable, Xiao Xi put in a lot of effort.
"Okay, I'll be right out!"
When Li Zexuan heard this, his heart was filled with happiness. Compared to his previous life, he was doing the same job, but his circumstances were completely different.
In his previous life, he spent his three years as a postgraduate student in the laboratory. Every day, he would enter the laboratory at 8: 30 a.m. to check in, and he would leave the laboratory at around 10 p.m. Of course, he would have to check in again. The person in charge of the project would check his attendance every month.
Sometimes, in order to rush the progress of the project, he would work overtime until one or two o 'clock, or even overnight. To put it nicely, he was a technician who worked hard on the frontline of research. To put it bluntly, he was just a worker, an engineering dog!
And now, although he was doing basic research, he had a pretty servant girl to take care of his daily needs, and there was also a "driver" on standby outside. Li Zexuan felt that he was willing to be such a happy engineering dog for the rest of his life!
"Hmm, it smells so good. What did Aunty Zhao make tonight?"
Li Zexuan walked out of the room and came to the main hall. Only then did he notice that the sky outside was almost completely dark. He sniffed with his nose and immediately smelled the aroma of food. Hence, he quickly walked to the dining table, picked up his chopsticks and prepared to eat.
"Hey hey hey, Young Master, you haven't washed your hands!"
When Xiao Xi saw this, she quickly pulled Li Zexuan and said.
"Uh … That's right!"
Li Zexuan looked at his dirty hands and felt a chill down his spine. It was a big taboo to eat without washing your hands after an experiment. What he did today was just a normal experiment. However, if he did not wash his hands when he used poisonous substances in his experiments, wouldn't he be in trouble?
When he thought about this, he quickly followed Xiao Xi to wash her hands before returning to the table to eat.
"Xiao Xi, have you eaten?"
"Young Master, of course, Xiao Xi will eat after you finish eating!"
"Hmm, so annoying. Sit down and eat with me. You know that I hate these rules the most!"
Xiao Xi looked at Li Zexuan awkwardly. In the end, she still went to get a bowl of rice for herself and sat opposite Li Zexuan. Anyway, it was not the first time. A few months ago, she and Xiao He ate at the same table as Li Zexuan at the Drunken Immortal Restaurant.
"Come, come, come. Eat a meatball and grow more meat!"
Xiao Xi: "… Thank you, Young Master!"
