Bright Sword: Starting from the Improved Grenade

As soon as he returned to Huangya Cave, Zhao Tianyang didn't take time to rest. He immediately found Liu Ransheng and asked him to take money to buy some aluminum ore and lead ore. If he couldn't buy them, he should go to the deputy director of the Political Department to solve the problem.

Batteries are divided into dry batteries: also called disposable batteries, such as the Nanfu batteries we often use, one is more powerful than six.

Storage battery: a rechargeable, reusable battery, such as a car battery, an electric vehicle battery, etc.

Fuel cell: directly generates electrical energy through the chemical reaction of fuel and oxidant. It is generally used in electric vehicles as an engine.

Solar cell: This should be easy to understand, it is to convert solar energy into electrical energy. The solar charging panels that we usually use are solar cells.

What Zhao Tianyang can make now is only storage batteries. Of course, dry batteries are also OK, but the demand is not great at the moment, so he will not do that for now.

There are several types of batteries, such as lead-acid batteries, nickel-iron batteries, and nickel-cadmium batteries. What Zhao Tianyang is going to make here is the relatively simple lead-acid battery, which is also the mainstream battery of this era.

If you want to do your work well, you must first sharpen your tools. Zhao Tianyang found Wang the blacksmith and Li Mutou who were repairing the factory.

"Master Wang, is Master Li okay?"

"No problem, this is similar to the tool we made last time when we were making propellant!"

Blacksmith Wang looked at the blueprint and assured, "Director, just wait and see. We can get it done in a day at most."

"Okay, then let's go down the mountain and get started!"

Zhao Tianyang called two more workers, formed a five-man assault team, and began to get busy.

After a busy day, Zhao Tianyang looked at the three tools in front of him and wiped the sweat from his head.

"Huh...finally done. Let's go back and rest first and come back tomorrow."

The next morning, Zhao Tianyang brought his men and tools to the blast furnace area. After more than ten days of development, the number of earthen blast furnaces has grown from two to four.

Last night, Liu Ransheng brought the lead ore and aluminum ore directly here and started smelting them in the furnace.

"How's the lead ore melted?"

"It's ready. Do you want to let it out?"

Chang San replied.

"Let it out."

Zhao Tianyang nodded and told Wang the blacksmith and others to move a pot-carrying machine, a generator, and a ceramic cylinder.

After everyone moved all the things over, Zhao Tianyang first poured 17% dilute sulfuric acid into the ceramic jar, and then put the crude lead that had just cooled into the jar.

"It's OK, let's generate electricity!"

After turning on the power, Zhao Tianyang directly placed the two stages into the ceramic cylinder. The electric current instantly spread throughout the ceramic cylinder, and the dilute sulfuric acid inside began to bubble and produce mist.

The crude lead also slowly underwent a chemical reaction, and some black impurity mud was discharged.

"Everyone, cover your noses and stay away."

Seeing this, Zhao Tianyang quickly reminded everyone.

After a while, Zhao Tianyang felt that the time was about right, so he covered his nose, walked to the boiler and turned off the generator.

Without the stimulation of electric current, the dilute sulfuric acid in the ceramic jar calmed down. After waiting for a while and waiting for the fog to dissipate, Zhao Tianyang led everyone to surround it.

After taking a look at the contents of the ceramic jar, Zhao Tianyang instructed: "Use tools to fish out the lead ingots and the black anode mud."

"The lead ingots are put into the blast furnace for further refining, the anode mud is dried, and then some petroleum is poured into the mixture and ignited to burn."

"Yes." X2

The group was divided into two groups, one responsible for refining lead ingots and the other responsible for burning anode mud.

"Those who burn anode mud, remember to wear a mask and stay away. It's not good to inhale too much of that gas!"

Zhao Tianyang reminded one of the group of people.

"Got it, Director."

Li Mutou agreed and quickly told everyone to wet the cloth and make masks.

Two hours later, Li Mutou and his men came back carrying a small ceramic jar. They could see that the originally black anode mud had turned into yellowish-brown lead powder after being burned.

"No problem, it was handled well."

Zhao Tianyang picked up some yellow-brown lead powder, looked at it, and nodded, saying, "Press the lead powder with a hammer. Make sure it is hammered into very fine particles."

"no problem!"

Blacksmith Wang confidently picked up the hammer and started hammering.

Soon, after everyone took turns hammering it, the originally rough lead powder turned into fine powder.

After the lead powder was hammered into powder, Zhao Tianyang asked someone to bring the mixer that was made yesterday, poured clean water into it, and then poured in some lead powder.

Then someone started to shake it, and the wooden blades inside the blender began to turn, and the lead powder and water gradually blended together.

The ratio is to add lead powder if there is too much water, and add water if there is too much lead powder. Stop when a paste-like substance is formed.

"Okay, that's fine."

Seeing the lead paste taking shape, Zhao Tianyang waved his hand to ask someone to stop cranking the handle and shouted to Li Tie beside him.

"Is the lead sheet ready?"

"OK OK."

Li Tie, who was concentrating on pouring molten lead into a steel mold and using the casting method to cast a hollow lead plate, quickly replied.

"This is the lead plate that has just been poured, polished and trimmed."

Chang San walked over with six lead plates and said.

"Ah."

Zhao Tianyang took the lead plate, or "grade plate" and nodded: "It's not enough, keep going!"

"Yes."

Chang San nodded, sat back, and continued to polish and trim the lead plate cast by Li Tie.

With the electrode plate, Zhao Tianyang had someone bring out a wooden table, put the lead paste and the electrode plate on it, and used a wooden scraper to scrape the lead paste onto the electrode plate.

Because there was no machine, Zhao Tianyang could only rely on his feel to scrape a layer of lead paste on both sides of the plate, then wrap it with white paper and take it to the dough pressing machine used to make propellant to compact it so that the lead paste and the plate would stick more firmly.

"Okay, take it to the blast furnace to dry it."

Zhao Tianyang handed the electrode covered with lead paste to Li Mutou who was standing beside him.

"okay."

After an afternoon of work, Zhao Tianyang and his team made more than a hundred lead plates and took them to dry.

"Okay, let's go eat first, and then we can work again."

Zhao Tianyang looked at the sky and said to everyone.

"Oh, time to eat!"

As soon as they heard that it was time to eat, everyone immediately put down their work and ran to the cafeteria.

"Director, hurry up! I heard there's pheasant soup today!"

Chang San also urged Zhao Tianyang who was walking slowly.

"I'm coming."

After dinner, everyone returned to the blast furnace area, put the dried plates into ceramic cylinders, and then poured in dilute sulfuric acid.

Dilute sulfuric acid will react chemically with the plates, turning them into negative plates.

Zhao Tianyang asked someone to take out the negative plate and take it to the blast furnace to dry again.

While waiting for the negative plates to dry, he released molten aluminum from the blast furnace and used the casting method to cast some particularly thin aluminum plates and several square aluminum frames.

A mixture of ceramic powder and clay is applied to these aluminum plates and frames, dried, and used for insulation.

(There are also aluminum partitions in the aluminum frame to separate six spaces)

After the aluminum plate and aluminum frame are made, the negative plate is also dried.

Zhao Tianyang took the negative plate and began to carefully polish and trim the negative plate again with everyone to make them all of uniform specifications.

After finishing these, you can start assembling the positive plate and negative plate.

(The negative plate is the positive plate if it is turned in the other direction)

At the same time, in order to achieve the insulation effect, the newly made aluminum sheet should be added between the positive and negative plates.

Originally, this thin plate should have been made of plastic, but plastic is a bit troublesome to manufacture, so Zhao Tianyang replaced it with an aluminum plate with added materials.

Six plates form a group, and a total of six sets of positive and negative plates can be assembled into a 12-volt lead-acid battery.

Use melted lead to cast the poles of the six sets of positive and negative plates and connect them.

Then you can put the prepared positive and negative plate groups into the square aluminum frame one by one. This is the battery shell.

Finally, a lead solution is poured onto the six sets of positive and negative plates so that they can be connected.

After the connection is completed, you can put on the aluminum cover. There are several holes in the middle and at both ends of the aluminum cover. The middle hole is used to add electrolyte (dilute sulfuric acid solution), and the holes at both ends are to expose the two positive and negative poles.

After putting on the cover, in order to seal it, pour molten aluminum liquid on the gap.

After sealing, you can pour in the electrolyte, and a 12-volt lead-acid battery is ready.
