Hand rubbing nuclear fusion live in the wilderness

Chapter 266 Hunting Time - Arrived!

While sending an old professor to the hospital, Won also simultaneously completed the preparation of the 'artificial SEI film'.

The tan solution is contained in a transparent special glass container, which looks a bit like iodophor, but much denser than iodophor, and this special glass container is connected to a power source.

At its bottom, there is an electric heating module, which controls the temperature through a temperature control resistor and a semiconductor thermometer to keep it at about 95 degrees.

95 degrees, to be precise, 92 degrees is the solid-liquid critical point of this 'artificial SEI film'.

When the temperature is higher than 93 degrees, this artificial SEI film material is in a liquid state.

And if it is lower than 92 degrees, it will solidify into a solid and attach to the material.

The reason why it is said that compared with the guided method, the growth inhibition method is simpler to produce tools and is more suitable for assembly line production is also here.

This thin film solution can be mass-produced through an industrial process and placed in a specific container.

As long as it is kept above 93 degrees, the artificial SEI film material will remain in a liquid state.

The most important thing is that the treated cathode lithium metal only needs to be rolled in a circle to be able to attach a layer of 'artificial SEI film' on it.

Some people may ask, how to control the thickness of the film in this way.

The South Korean won will give the answer, no need to control.

As long as the coating is not covered more than three times and the coating is too thick, the artificial film formed by the artificial SEI film solution on the lithium metal will not affect the conductivity and inhibit the formation of lithium dendrites.

This is the most powerful part of this artificial SEI film.

It is simple, convenient and fast, does not require expensive ion plating machines, and does not require manual processing. It can be produced on ordinary dust-free assembly lines.

If there is any disadvantage, it is that this artificial SEI film will weaken the performance and life of lithium-sulfur batteries to a certain extent.

In addition, every charge and discharge will affect the state of this film.

When the charge and discharge times reach about [-] times, the plating layer attached in this way will have a probability of falling off.

The more times, the greater the probability.

Here is a note, the 'charge and discharge' here refers to the number of times, not the charge cycle.

The two concepts of charge and discharge times and charge cycles are different.

Let's take an ordinary lithium battery as a very simple example.

If a lithium battery only uses half its capacity on the first day, then fully charge it.

If it is still the same the next day, that is, charge half of it, and charge it twice in total, which can only be counted as one charging cycle.

The number of charge and discharge is a different concept.

Even if you only use one percent, the remaining 90.00% nine, if you fill it up, it will be occupied twice.

Once for discharging and once for charging.

In other words, four thousand charge and discharge times can only be counted as two thousand charge cycles, or even less.

In this case, if you want to maximize the use of this battery, it is the most cost-effective way to consume the power to one percent or zero percent at one time and then recharge it.

Won has no doubt that countries around the world will manufacture this lithium-sulfur battery, but if it is applied to mobile phones, it is estimated that some people's obsessive-compulsive disorder will be cured.

After all, once the battery power of many people's mobile phones is lower than 30.00%, they will feel insecure and will immediately find a charging cable to charge their mobile phones.

But in this case, it will reduce the service life of the mobile phone battery.

However, relatively speaking, two thousand charging cycles are already excellent, far exceeding the lithium batteries currently produced by humans.

At present, the battery used by major mobile phone manufacturers, the life of the lithium battery is basically [-] charging cycles.

The so-called five hundred times means that the manufacturer has achieved about 80 five times of charging at a constant depth of discharge (620%), and finally reached five hundred charging cycles.

Simple understanding, in fact, after 100 charging cycles, the capacity of the battery is reduced from 80.00% of the factory to [-]%.

Every charge cycle will reduce the battery capacity a little.

It’s just that the reduction in power is very small. If the quality is good and the quality is high, the battery can still retain 80.00% of its original capacity after multiple cycles.

This is the same as a special battery health reminder on a certain fruit phone. When it drops to 80.00%, it will take the initiative to remind you that it is time to spend hundreds of dollars to replace the battery.

This is actually a routine of capitalists, called: "Planned to be scrapped!"

That is, products that are deliberately designed to be easily damaged, thereby prompting people to replace the product in their hands.

'Planned obsolescence' was originally applied to one of the most common products - the light bulb.

In the 20s, several of the world's largest electrical companies and major light bulb manufacturers banded together in a secret agreement.

Its purpose is to increase product profits by adjusting product prices and production quotas. Among other things, this secret agreement stipulates the lifespan of the light bulbs.

Before this agreement was signed, the average lifespan of the bulbs was 2500 hours.After the agreement was signed, the average lifespan of the bulbs was reduced to 1000 hours.

This was the predecessor of 'planned obsolescence': the 'Phobos Cartel'.

It's disgusting, but now it has penetrated the entire world, in every aspect.

For example, the extremely fragile heating element in the washing machine, the electric toothbrush with a sealed panel that cannot replace the battery, the battery in the mobile phone, and so on.

Now have a limited lifespan.

The artificial SEI film prepared by Korean Won is actually similar to the 'planned scrap' to some extent.

It's just that one is that it can only be used so many times due to technical limitations, and the other is to artificially add the number of times of use to it.

Although similar, the meanings of the two are completely different.

After completing the manufacture of the artificial SEI film, it was already past four o'clock in the morning, and Won yawned, looking a little sleepy.

Even with his perverted physique, he couldn't bear the full seven hours of concentrated work in one night, plus more than ten hours during the day.

This is completely different from 996 and 007. Although 996 and 007 are tired, they will still fish in the middle, not to mention working for more than ten hours.

He is different, he is really doing things down-to-earth, the kind who concentrates on it.

After all, a little carelessness may lead to the failure of the experiment.

If ordinary people do things like him, let alone more than ten hours a day, their brains will shut down if they exceed four hours.

No way, the human brain is so fragile and sophisticated.

Ordinary people don't have gene enhancement medicine and human body development medicine to strengthen the body, and it is impossible to use the system to improve the body attribute points like him.

The brain is also an organ that consumes a lot of energy. It is overloaded, just like the CPU, and sooner or later it will have a fever.

Yawning, Han Yuan got up and used a simple kettle to boil water and make a cup of coffee.

These coffee beans were also found by the capuchin monkeys.

It was just an accident, these coffees were the seeds attached to the baba pulled out by the capuchin monkeys who ate the coffee beans somewhere, took root and germinated in the plantation and grew up.

Before, the capuchin monkeys took his nutrient solution to cultivate these things.

Won doesn't have much interest in things like cat poop coffee, elephant coffee, or monkey coffee.

The thing he drank the most to refresh himself was Red Bull, an artifact from the days when he played games all night.

But there is no Red Bull now, so it's okay to use coffee instead.

After drinking a large cup of steaming coffee, I have to say that the coffee cultivated with nutrient solution tastes quite good.

As for how far it can go, and what kind of coffee it can be compared with, I don't know, after all, he rarely drinks coffee.

Coffee can refresh you, but the effect is not so fast. Taking advantage of this time, Han Yuan is going to squint for a while.

He used to do this a lot in middle school and high school.

Every time before returning home from vacation, he would go to play games all night, buy a bottle of Red Bull after all night, and then drink it while driving back to his hometown for a few hours, and then sleep in the car. .

It's a pity that this method was no longer available after entering high school. The boring teacher went to visit his hometown, and then Han's mother found out that the holidays are usually in the afternoon, not in the morning.

As a result, Han Yuan ate an unforgettable meal of fried pork with bamboo whip.

After squinting for about half an hour, Han Yuan opened his eyes, and the boredom in his eyes lessened a little.

Whether it's closing his eyes and resting, or the coffee is working, at least he can continue to work now.

For the detection of artificial SEI thin films, it is necessary to prepare the battery as a whole and use related instruments to do it.

But he can't do this test now, not because he doesn't have the equipment, but because the corresponding computer program hasn't been compiled yet.

The field emission scanning electron microscope used for detection needs to be connected to a computer to save the detected information, but his current computer does not support this function at all.

This is also the reason why the South Korean won was going to deal with the lithography machine first and then the high-energy storage lithium battery.

Because he needs to get the integrated chip out and upgrade the computing core of the computer, the upgraded computing core can facilitate him to write programs and then handle other things.

But the appearance of that giant python disrupted his arrangements and plans.

Originally, it took two or three days to complete the preparation of related materials for the lithium-sulfur battery, and then after the electric propulsion engine was tested, he could start to manufacture the lithography machine to upgrade the computing core.

However, now Han Yuan can only put down the matter of manufacturing lithography machines and deal with this python first.

In other words, he has to use the lithium-sulfur battery that has not been tested in detail first, and then do the test after it is used up.

This does not meet the requirements, there may be some risks and problems, but he has no other way.

Fortunately, some basic tests can still be done, such as charge and discharge test, drop test, vibration test, etc., and these tests can be used to determine whether the battery can work normally.

After passing these tests, there is no big problem with the temporary use of lithium-sulfur batteries.

After all, the formation of lithium dendrites does not cause irreversible damage to the battery after a few charges and discharges. This is a relatively long process, but the damage is too great.

After solving the problem of artificial SEI film, the rest is assembly.

Cathode lithium metal, anode sulfur mesoporous carbon composite material, organic electrolyte, polyolefin porous diaphragm, thermistor, casing.

These are the materials that make up lithium-sulfur batteries.

Among them, the polyolefin porous film, thermistor, and shell were not manufactured this time.

Because he had made these things when he was making batteries before, and he could just take out the ready-made ones and use them.

And these things are not some black technology, there is no need to broadcast and manufacture them again.

Manual assembly of high-energy storage lithium-sulfur batteries by hand is completely inconsistent with the system's knowledge and information.

Whether it is cleanliness, manual plating of organic electrolyte, or packaging of polyolefin porous film, some mistakes may occur in the process of manual assembly.

This is also one of the reasons why Won prepared to prepare a lithography machine first.

He needs to control the production and assembly of lithium-sulfur batteries through computer programs.

But the situation is different now, and he can only rub a few batteries with his hands first to get rid of the python and then deal with other things.

Fortunately, the assembly of lithium-sulfur batteries is not only done by machinery, but manual assembly is also possible. It’s just that manpower has no advantage over machinery for such a large amount of boring and repetitive work.

The parts and materials are all ready, and the assembly of lithium-sulfur batteries is almost no difficulty for South Korean won.

What's more, he is not purely manual, and there are still related industrial equipment, but manual operation is required.

Negative electrode homogenization, positive electrode homogenization, coating, rolling, slitting, baking, winding, welding and other steps in sequence did not take much time.

At around six o'clock in the morning, the first square lithium-sulfur battery appeared in the hands of South Korean won, followed by the second, and the third
Until the hand stopped, a total of six lithium-sulfur batteries were neatly stacked on the assembly table.

This amount is enough, and the capacity of lithium-sulfur batteries is far higher than that of ordinary lithium batteries, not to mention that the lithium-sulfur batteries prepared this time are not small.

These lithium-sulfur batteries are applied to "electromagnetic weapons", and the specifications of length, width and height are: 20cm*10cm*10cm.

Calculated according to this volume, its capacitance should be around 500ah, which is 500000mah.

The battery that Huaguo made for testing was about the same size as this one, but the capacity was ten times worse.

A battery of this capacity is enough to be assembled on an electromagnetic rifle and brought to the battlefield.

According to the power consumption of [-] mAh per shot, this kind of battery can fire [-] shots continuously, which is much higher than the magazine capacity of ordinary rifles.

Take the ordinary ak47 as an example, its ordinary arc magazine is [-] rounds of bullets.

There are still some disadvantages, such as weight.

In terms of weight, this lithium-sulfur battery is much heavier than the ordinary curved magazine of ak47.

The weight of a bullet is about ten grams, and the specific weight is not clear, but based on this weight plus the magazine, the weight of the entire magazine should be about [-] grams.

The lithium-sulfur battery on the assembly table is not light. Although it has not been weighed, it is estimated to be about [-] kilograms.

Although a lithium-sulfur battery can fire fifty shots, the number of 'bullets' that can be carried is actually reduced when the weight difference is nearly three times.

The battery is assembled and all that remains is to conduct preliminary tests on it.

No matter what kind of battery, the first thing to do is to give the battery a certain amount of current to activate the positive and negative active materials of the battery.

The activated battery has the ability to discharge.

After this step is processed, it is the charge and discharge test, drop test, vibration test, etc.

After completing these preliminary tests, it was already past eight o'clock in the morning, but the number of people in the live broadcast room did not decrease but increased, reaching tens of millions.

Although most people couldn't understand the previous preparation steps, no one left.

Everyone is waiting for Won to complete the test and then demonstrate the power of 'electromagnetic weapons'.

When Han Yuan walked out of the dust-free workshop with the lithium-sulfur battery that had completed the preliminary inspection, the live broadcast room suddenly became excited.

【Is it done?Is this done? 】

[After a day of hard work, it seems that it is finally done. 】

[Should the anchor test the power of the electromagnetic rifle first?See if you can kill a fly. 】

[From the beginning of making fireworks and black powder to now making electromagnetic guns, anchors are becoming more and more judges these days. 】

[When will you find trouble with that snake?I heard it is tens of meters long? 】

[I think it's better to test it first, what if it doesn't kill anyone?What if it exploded?What if the battery explodes? 】

[By the way, don't electromagnetic weapons consume a lot of power?How many shots can be fired with one battery? 】

[A battery that will not explode is not a good battery_]

On the virtual screen, the already dense barrage became more dense now. After more than 20 hours of continuous simmering, the lithium-sulfur battery was finally released, which made the audience squatting in the live broadcast room very excited.

In fact, the topic should have been the lithium-sulfur battery itself, but at the moment most of the audience is discussing electromagnetic weapons and the unknown python.

The unknown is mysterious and attractive enough.

In contrast, the black-tech lithium-sulfur battery itself, which surpasses human technology, has received little attention.

With the manufactured lithium-sulfur battery, Han Yuan hurried back to the living room. After one night, he was worried that something would happen to the two children and the capuchin monkeys.

It wasn't that he was worried about being eaten by the python, but that the two little monkeys and the capuchin monkeys didn't listen to his instructions, ran out without permission to trigger the warning device, and then were electrocuted into Muggles.

Although at night he also took the time to go back and take a look and repeat the instructions, but it is already daytime after all.

Fortunately, when he hurried back to his place of residence, Han Yuan saw Leopard [-] and Leopard [-] playing and fighting with each other at a glance.

Seeing Han Yuan approaching, the two boys stopped their fight immediately and rushed towards him, yelling aggrievedly, as if they were asking when they could go out to play.

After all, for a feline animal, especially an energetic jaguar like Liangxiao who runs around all day long, it is impossible to live without going out for a few laps.

Seeing that the two were safe, Han Yuan smiled and comforted him, checked the surrounding situation, and disconnected the power supply of the high-voltage power grid after confirming that there were no traces of python invasion.

Seeing this, the clever two little ones ran away, ready to go out for a carnival, but before they could go a few steps, they were stopped by Han Yuan again, so they had to run back sullenly and lay down on the ground.

Han Yuan yelled to stop the two children, and then called down the capuchin monkeys perched on the tree, then took them to the farm, pointed to the snake marks on the ground and began to mutter.

He needs the help of the two little ones and the capuchin monkeys to find the python that attacked the farm, and come back and tell him as soon as he finds it.

After all, the sense of smell and sense of animals is much more sensitive than that of humans.

After explaining for a long time, and confirming that the two boys and the capuchin monkeys had figured out that they were looking for snakes instead of desperately, Han Yuan raised his head and looked at the virtual screen.

"Just now I asked the two little monkeys and the capuchin monkeys to look for the python that attacked the farm. If there is any news, they will return to me as soon as possible."

"Now take advantage of this time to test the power of electromagnetic weapons."

Saying that, Han Yuan dragged out a wooden box from the living room, and took out the well-preserved electromagnetic rifle and electromagnetic sniper rifle from it.

Two very sci-fi weapons were once again presented in front of everyone, and there was an impatient urging on the barrage.

Han Yuan smiled and said, "No rush."

After speaking, he took out a few more blank sheets of paper, drew several concentric circles on them with a pen, and then took them with him to the test site for testing electric propulsion engines.

There is a high temperature resistant concrete wall built before, which can be used as a target for testing.

Pasting the white paper made of paper on the concrete wall, Han Yuan took the electromagnetic rifle away from the target, ready to start the test.

At this point, the live broadcast room became quiet, and the number of barrage on the virtual screen decreased sharply. Everyone was engrossed in the live broadcast, waiting for the test to start.

After the lithium-sulfur battery was installed, Han Yuan skillfully turned on the switch on the end of the gun, and a light green indicator light lit up on the end of the gun.

The configured magazine is installed, and the spring inside automatically sends the first solid alloy bullet into the chamber.

The slight 'click' came into Won's ears, and he knew that everything was ready.

The 'electromagnetic rifle' is very heavy, weighing more than ten kilograms.

But this weight is no pressure at all for the current Korean won, and it can be picked up with one hand, just like holding a pistol.

The long and narrow gun body was aligned with the arm, aiming at a target not far away.

"here we go."

Han Yuan said something lightly, closed one eye slightly, aimed at the white paper on the concrete not far away, groped for the launch switch with his fingers, and pressed it lightly.

The high-speed spinning bullet was ejected from the chamber, and the audience in the live broadcast room didn't even notice anything. Countless cement blocks exploded on the concrete wall not far away.

Followed by the second shot, the third shot, the fourth shot
The continuous alloy bullets hit the concrete wall, making loud crashing sounds, and gravel powder flying all over the sky, blocking most of the camera.

When the Korean won stopped and the dust dispersed, the originally intact concrete wall was now in tatters, the white paper pasted on it as a target had long since disappeared, and a lot of blasted rubble had piled up on the ground.

And the scariest thing is the bullet marks on it.

As Han Yuan approached with the shooting device, the scene that caught the eyes of the audience in the live broadcast room made everyone gasp.

The half-meter-thick concrete wall has holes that are bigger than a thumb, and the front and back are transparent, and the light from the opposite side can be seen.

Obviously, this was directly punctured.

The terrifying power frightened the audience in the live broadcast room. There was a complete silence in the live broadcast room for a while, and then a flood of bullet screens ushered in.

【Fuck! 】

[Fuck, what a terrifying power, a half-meter-thick concrete wall, it can be pierced through with a single shot? 】

[Fuck, AWM! 】

[What AWM, this is clearly AWP! 】

[L115A3! 】

[Stop arguing, let's use the method of elimination first, first of all, this is not an Italian gun——]

[AWM does not necessarily have such great power, anti-equipment, it is possible for anti-equipment to penetrate such a thick concrete wall. 】

【What the hell will happen if you hit someone with a gun? 】

[It was directly broken into two quarters! 】

[Man's romance! 】

[This short electromagnetic rifle is so scary, what about the long sniper rifle on the ground?One shot down and the sky collapses? 】

[Anchor test it out! 】

[Yes, what about the power of the sniper rifle?Looking at the situation, it should be no problem to penetrate a one-meter-thick concrete wall. 】

The bullet screen was densely packed like a flood, and the terrifying power of the electromagnetic rifle stunned everyone in the live broadcast room, but it excited the audience in front of the screen.

Not to mention the audience, experts from various countries squatting in the live broadcast room gasped, including Hua Guo, who had already tested the electromagnetic rifle, was a little confused.

When they tested it before, it wasn't that powerful.

What is this scenario?Battery problem?
A half-meter-thick concrete wall can be penetrated with a single shot. I am afraid that only large-caliber sniper rifles and anti-materials can do it.

Looking at the shocking barrage, Han Yuan smiled and explained, "You guys overestimated the power of electromagnetic rifles."

"Although it directly penetrated a half-meter-thick concrete wall, it has something to do with the quality of the concrete wall."

"When testing the electric propulsion engine before, in order to improve the high temperature resistance of these concrete walls, a lot of other materials were mixed into it."

"These things reduce the strength of the concrete to a certain extent, so it's not uncommon to go straight through."

"Even gunpowder weapons can actually penetrate this wall."

After a pause, Han Yuan added: "Of course, that may require a larger caliber."

"Okay, let's test another weapon 'Electromagnetic Sniper Rifle'.
Before he finished speaking, the roar of a jaguar was heard not far away.

Han Yuan turned his head to look in surprise, not far away, the two children were running towards this side quickly.

Within a few seconds, Leopard [-] and Leopard [-] rushed to Han Yuan and started yelling at him.

Seeing this, Han Yuan immediately ran to the other side, picked up the electromagnetic sniper rifle placed on the ground, and followed the two boys.

Obviously, the two boys found the python.

　This month's update, I have no face to ask everyone for a monthly pass ヾ(ω`)o.

　　There is no longer a falg. There are too many things in the Net Association, ε=(ο｀*))) Alas.
