Development of productivity started in 1981

Chapter 134 Application of Graphene Batteries

On August 1982, 8, Wang Jiankun returned to his hometown of Wuyuan with his seven disciples and Wu Xiaoyi.

"Jiankun, I'll go home first. Thank you again for taking me to experience this unique BJ trip. Goodbye." Wu Xiaoyi said goodbye to Wang Jiankun at the pier under the Dongmen Bridge.

"Goodbye, see you at the start of school. Go back and work hard, and let's go to school together in BJ."

"Okay, see you when school starts." After saying that, he left with a trolley case.

After Wu Xiaoyi left, Wang Jiankun brought his seven disciples to the waste recycling station.

However, they no longer recycle general waste. They only collect a few metals such as scrap steel and copper. The rest are recycled by a newly opened waste recycling station next door.

Ye Wei and his wife are mainly responsible for looking after the laboratory here, and do some handicrafts by the way.

There was still a recycling station sign hanging at the door, with an explanation that it only accepted scrap metal.

"Jiankun, you're back. The rice has been cooked for you, and the vegetables have been washed and cut. We're just waiting for you to come and put them in the pot."

When Ye Wei saw Wang Jiankun and his men enter the yard, he indicated that he was ready to cook.

"It's already 11 o'clock, let's start cooking!"

"Zheng Qian, Yu Zirun, you two can lend a hand. It will take a while for so many people to eat."

"Fang Guihua, the rest of you go put your luggage away quickly, then come out and tidy up the tables and chairs to prepare for dinner."

With the help of someone, a large table of food was quickly prepared. Wang Jiankun asked Ye Wei and his wife to sit down and eat together.

"Jiankun, is BJ fun? Is Tiananmen Square very big? Did you watch the flag-raising ceremony?" Ye Wei asked curiously during the meal.

"It was fun. We woke up at 4 a.m. to watch the flag-raising ceremony. The square was packed with people. The square was very large, even larger than our school."

"Such a large square, and it's packed with people. There must be tens of thousands of people watching the flag-raising ceremony, right?"

"No, but there were about 10,000 people. We took a lot of photos and will show them to you later."

"Okay, that's great. I don't know when I can go to BJ to check it out."

"You two should work hard! Sister Ye, I see you can read, so you should have been to school for a few years, right?"

"Well, I graduated from elementary school and attended junior high school for one year. If my family couldn't afford it, I would have probably taken the entrance exam for a technical secondary school."

"Well, my uncle is planning to invest in another factory in the county. Would you like to work as an accountant in the factory?"

"Working as an accountant in a factory? I haven't read a book in many years, and I've never worked as an accountant before. Can I do it?"

"Sure. You've just graduated from elementary school. You said you have the grades to get into a technical secondary school. Then it's no problem for you to be an accountant. It doesn't matter if you don't know how to do it. Someone will train you when the time comes."

"Is that so? I'll go, but I don't know what the salary will be like?"

"That's definitely better than what you have here. You should get 60 yuan a month at first, and if you work hard, your salary and position can be improved."

"60 yuan a month? I'll go, but can I leave Ye Wei here alone?"

"It's fine as long as Ye Wei is here. We can slowly stop recycling waste in the future. If someone comes, we can introduce them to the one next door. From now on, this place will mainly be used as our laboratory and gathering place. It will be fine as long as someone is watching over it."

"Jiankun, you've been so kind to us. I will definitely keep an eye on you."

"I've seen how you've been doing over the past year. Now that there's a better opportunity, I'll give it to you. If you work hard, your life will get better and better. Then you can go to BJ."

Wang Jiankun gave Ye's sister-in-law a chance because he saw that the two of them had been diligent and clean over the past year. Wang Jiankun didn't pay much attention to them in the second half of the year, but he never found any bad behavior from them in the hidden surveillance.

After lunch, Zheng Qian and Yu Zirun went home together.

Wang Jiankun asked them to come in a few days to get some advanced professional books, which were all projected by Wang Jiankun from many libraries in BJ. They were also proofread by Zhizi and some errors were corrected.

"Are you five planning to go home or continue your research here?" Wang Jiankun asked Fang Guihua and others.

"We plan to go home for two days before coming back. We bought a lot of local specialties in BJ this time, and took a lot of photos to bring back to our family."

"Okay, then I won't see you off. It should still be in time to catch a ride now. Be careful on the road."

"Okay, goodbye, Jiankun."

After Fang Guihua and the others left, Wang Jiankun asked Ye Wei and his wife to go into the house to rest, while he began to extract elements and manufacture some instruments and equipment.

This trip to BJ was extremely rewarding. Zhizi absorbed a lot of basic knowledge. At the same time, with the help of Zhizi, Wang Jiankun gained a deeper understanding of subjects such as chemistry, physics and biology.

So he took this opportunity to upgrade the laboratory, add some experimental instruments, and adjust the internal structure of the laboratory.

First, in the laboratory used by Fang Guihua and his team, Wang Jiankun made a new 3D printer that can print metal materials.

This new 3D printer was created by Wang Jiankun based on the research of several schools.

First of all, the laser was miniaturized by Wang Jiankun based on the research of a certain research institute.

The laser intensity is sufficient to sinter metal powder within microseconds, and the duration is sufficient.

Then the positioning system is also very advanced, using a new type of stepper motor, combined with Wang Jiankun's atomic-level processing capabilities, so that the displacement accuracy can reach 1 micron.

To be honest, this level of precision is enough to use lasers to directly lithograph chips, but Wang Jiankun has no plans to speed up silicon chips for the time being.

At present, Wang Jiankun has combined the material research of many schools to produce three types of metal powders, which are three alloys mainly composed of iron, aluminum and copper.

After the 3D printer was built, Wang Jiankun made three kinds of powders and then used the laboratory's original computer to draw a part of an F3 aircraft.

After drawing, Wang Jiankun started the printer. He saw the equipment at the feed inlet began to evenly coat the bottom of the machine with a layer of powder. Then the laser head at the top emitted a laser that was invisible to the naked eye. As the laser head continued to move, the outline of a part appeared at the bottom.

After one layer is printed, the device lays another layer of powder, and then the laser head starts working again. The process is repeated, and the drawn part is formed little by little.

In fact, this production process is similar to Wang Jiankun's use of superpowers to manufacture. The main difference is that Wang Jiankun uses superpowers to mobilize and fix elements, while 3D printers use the energy of lasers to solidify elements.

At present, Wang Jiankun has not figured out what kind of energy this superpower utilizes, and the information he collected did not provide any inspiration.

However, it does not affect his use at present, and the more he uses it, the larger its range of effect becomes.

The printer worked for nearly an hour to make this small part. In terms of efficiency and energy consumption, the 1D printer is not up to standard. However, its advantage is not in mass production. At present, its best use is to make some samples.

After the manufacturing was completed, Wang Jiankun used his super powers to observe the internal structure of the parts and found that there were still many gaps, but they were not visible from the outside. However, if the strength tester was used, it would be found that the strength did not meet the standard. In addition, the appearance was relatively rough and did not achieve the mirror effect.

However, these are the directions we will work on in the future. Now that we have made a good start, Wang Jiankun plans to let Fang Guihua and others try it out first, and then register a patent while giving it to his uncle for trial use.

When the conditions are ripe and we have made contact with domestic military industrial departments, we can also provide them with the equipment to speed up the progress of domestic weapons research and development.

After the printer was manufactured, Wang Jiankun upgraded Yu Min's laboratory. On the one hand, he upgraded a small space inside it into a Class 1,000 clean room, and then provided him with a metal organic compound chemical vapor deposition equipment.

He had always been troubled by how to grow gallium nitride thin films on sapphire. Although Wang Jiankun had already passed the physical test of blue light-emitting diodes, he was still stumped by this level.

Among the information Wang Jiankun collected this time, there were some related thin film manufacturing research. When Zhizi was sorting it out, he provided such a thin film generating device.

After designing it, Zhizi also conducted some simulations to confirm that this device could produce the thin film that Wang Jiankun needed.

In fact, at this stage, blue light LEDs are ready for mass production, because the biggest problem has been solved. What remains is how to transform laboratory preparation into industrial production.

However, Wang Jiankun decided to wait a little longer. He planned to let Yu Min use this equipment for trial production while thinking about how to modify it to facilitate large-scale production.

After all, this equipment is not the kind that can carry out assembly line operations. The reaction time of each furnace will be as long as 4 hours, and the preparation time also takes 2 hours. Then each furnace can only process the area of ​​a circle with a diameter of 3 inches.

This efficiency is not enough for large-scale mass production and requires transformation, which requires continuous optimization in actual production.

After Wang Jiankun completed the manufacturing, he started the equipment to trial-produce a furnace, and then used his super powers to cut out 2400 blue LED particles.

He then used the device to create green and red LEDs, and combined the three to create a display screen 40 centimeters long and 30 centimeters wide.

An external control circuit designed by Tomoko was then connected, and the photos taken in BJ were digitally transcribed to the display screen.

Wang Jiankun pressed the play button, and a paper-sized photo appeared in front of him.

Because the cut LED particles are relatively large, the pixels are very low when viewed up close and the graininess is very obvious, but it is still relatively good if you look from a distance.

After appreciating this work that he created on impulse, Wang Jiankun kept the display screen and also made a paper version of some of the manufacturing principles, preparing to leave it to Yu Min for research.

However, in the initial stage, the focus will definitely be on equipment transformation and industrial production exploration. This display screen can be regarded as an assessment target left for it.

It was almost midnight when Wang Jiankun finished working on the display screen. After packing up, he returned to the underground base.

The next day he continued with the laboratory renovation, and this time he provided Lang Junjian with a high-performance workstation.

The internal chip was designed with the help of Zhizi. A single chip has 1.2 million transistors, and the manufacturing process should have reached the 1-micron level according to traditional manufacturing methods.

This workstation has eight of these chips, and its computing speed can reach 8 million times per second, which is more powerful than the mainframe that has been announced to be successfully manufactured in China.

Its memory also reaches 20GB. Wang Jiankun used three-dimensional packaging, that is, stacking multiple layers of storage units per unit area. In this way, the memory area remains unchanged, but the storage capacity is increased by more than 3 times.

In fact, it is also possible to produce a larger storage capacity, but it is not needed at present. Wang Jiankun produced the current performance for Lang Junjian to test, and when the time is right, it will be produced by Xingyao Electronics.

Now, in order to bring out the performance of this workstation, Lang Junjian still has a lot to learn.

Wang Jiankun found a lot of materials suitable for his research, such as the principles of electronic maps, plane positioning and three-dimensional coordinate positioning methods, etc.

As for the information for Yu Zirun and Zheng Qian, Wang Jiankun had already asked Chieko to sort it out, and there were both original foreign language versions and translated versions.

After completing the renovation and update of his disciples' laboratory, Wang Jiankun returned to the underground base and began to transform the base.

The first thing he modified was the lighting system. He replaced all the light sources with LED lights, and they were the test version with the highest brightness.

After the lights were replaced with this kind of heat-free LED, he felt that the underground base became a little cooler.

They had used incandescent lamps before, but Wang Jiankun thought turning the lights on and off was a waste of time and that the electricity would not be used up, so the lights in the base were always on. With thousands of lamps on, a lot of heat was generated.

He then made several batteries with graphene as the base electrode and conducted charge and discharge tests.

Graphene acts as a supercapacitor inside the battery, which can store current like a traditional battery and can also charge and discharge quickly.

The speed of electrons in graphene reaches 1/300 of the speed of light, far exceeding the speed in ordinary conductors.

Graphene also has the characteristics of high conductivity and high specific surface area, which can greatly reduce the size of the battery.

When Wang Jiankun tested it, he found that according to proportional calculations, this graphene battery can store 1000Wh per kilogram, which will greatly reduce the volume of the energy storage system.

After conducting thousands of charge and discharge tests, Wang Jiankun found that this battery is so excellent that it has great advantages over lead-acid batteries, and even over the lithium batteries he made with his superpowers.

The charging and discharging speed is extremely fast and very little heat is generated in the process.

So Wang Jiankun asked Zhizi to help design a graphene energy storage system that can store 2 kWh of electricity.

When Zhizi completed the design, Wang Jiankun was shocked. The volume of the entire system was less than 1 cubic meter, and most of it was occupied by auxiliary components such as wires and inverters.

Now that the design is complete, it’s time to start manufacturing. Wang Jiankun mobilized the elements stored in the base and carefully manufactured this super battery.

The first step is of course to make the shell. At the selected location, the insulating shell grows little by little from bottom to top.

Next is the graphene inside. Wang Jiankun carefully controls the carbon element and manufactures it piece by piece.

He was so careful because he was afraid of problems, because this structure was very precise, almost the same as the nuclear reactors made before, and the graphene sheets were even more precise.

Layers of graphene stand inside the battery like a honeycomb. Because there are so many layers, if you open it up, you can see refracted light of different colors.

After the main structure was manufactured, Wang Jiankun filled it with electrolyte and then sealed it. The external equipment was much easier to handle. Wang Jiankun used gold and silver as the main structure of the wires to maximize the performance of this battery.

When the battery was manufactured, Wang Jiankun started the reactor. At the beginning, Wang Jiankun charged a small part of the electricity into this battery. After the lead-acid energy storage system was full, Wang Jiankun charged all the electricity into this graphene battery.

Wang Jiankun was fully focused during this process. If there was any problem with the battery, he would immediately use his super powers to intervene.

However, Zhizi's designs have always been very reliable, and there were no problems during the more than 10 hours of charging process.

After the battery was fully charged, Wang Jiankun reduced the power of the reactor to 10% power, and then made 5 batteries that could store 2 kWh of electricity and let the reactor slowly charge them.

Because Wang Jiankun is going to start a series of high-energy-consuming experiments, the amount of electricity required will be extremely huge.

The existence of these batteries makes it possible for Wang Jiankun to use a large amount of electrical energy in a very short period of time.

After the graphene battery was manufactured and the corresponding peripheral circuits were arranged, Wang Jiankun began to prepare for the research, development and testing of laser weapons.
