Hand rubbing nuclear fusion live in the wilderness

Chapter 253 Super Simple Nuclear Reactions

(Chapter 249 and the three chapters are gone. When I woke up today, the ones that were unlocked yesterday, including those modified later, were all screened. o(╥﹏╥)o)

After briefly explaining the lithium-sulfur battery and the solution to the problem of lithium dendrite growth, Won started to prepare the electrolyte.

A battery is actually a device that converts chemical energy into electrical energy, and there are many factors that affect the capacity of a battery.

For example, the structure and quantity of the plates, the quality/temperature/density of the electrolyte, the discharge conditions, etc.

But there is no doubt that the electrolyte is one of the most important components of a battery.

And this time, Won prepared two kinds of electrolyte solutions.

One is a salt solution ionic liquid electrolyte.

The other is an organic solution electrolyte.

The reason why two kinds are prepared is because of the application of the battery.

Different from the use of ordinary batteries such as TV air conditioner remote controls, this time the high-energy storage batteries he manufactured are applied to aircraft.

Just like using batteries on new energy vehicles, it sometimes needs to work in harsh environments.

Such as severe shocks, such as low temperature or high temperature.

These problems that will be encountered during the flight of the aircraft must be taken into consideration.

In addition, the battery prepared this time is not a cylindrical shape like an ordinary AA battery, but a rectangular parallelepiped shape similar to a lead-acid battery or a blade battery.

Therefore, the stability, safety, discharge capacity and other aspects of the battery must be considered in advance.

Salt solution ionic liquid electrolytes and organic solution electrolytes each have their own advantages.

The salt solution ionic liquid electrolyte is relatively viscous, somewhat similar to a non-Newtonian fluid, it is not easy to flow easily when stored in a battery, and has excellent properties in terms of shock resistance.

The organic solution electrolyte uses an organic solvent as the electrolyte, which can more effectively solve the corrosion problem of metal lithium, and has good charge and discharge performance and conductivity.

Both have their own advantages and disadvantages, so Won intends to prepare both of them, and then make two different lithium-sulfur batteries before conducting battery charge and discharge experiments.

Finally, it is determined that the electrolyte is better and more suitable to use.

Anyway, the preparation of the electrolyte is not difficult for him, especially with the support of elementary chemical application knowledge and information, it is easier to handle.

When Han Yuan expressed his thoughts, many viewers in the live broadcast room were attracted.

After all, batteries, everyone has played with them since childhood.

From the four-wheel drive when I was a child to the electric stick when I grew up. Ahem, mobile phones have batteries inside.

Many viewers stared at the live broadcast with interest.

Thinking that since this anchor can make it, can they make it if they have the materials?
There are even some nimble people thinking about whether it is possible to borrow Korean won's technology to set up a battery production plant or production studio?

This kind of high energy storage battery is definitely very promising.

[Two different electrolytes, really amazing. 】

[The anchor can the anchor teach you the details while doing it?I also want to learn. After I finish learning, I will try to see if I can do it myself. 】

[The above is reasonable, and so am I! 】

【Me too. 】

[+1, it’s also good to play with DIY. 】

【Aren't you afraid of sending you to heaven with a bang? 】

[Upstairs, you underestimate the anchor's technology too much. The alien's technology is as bad as you think. 】

[I think I can do it too, build one and put it on my little eDonkey, it should be fine for a month without charging, right? 】

[It's smaller, the layout is smaller, and it can be used for at least a year without charging. 】

【Ride on my beloved small motorcycle, it will never be stuck in traffic.】

On the virtual screen, there was a lot of discussion on the barrage, and many people were talking about whether it is possible to make one and try it out.

Han Yuan had just finished processing the polyester compound. He looked up and saw these roads. After thinking about it, he smiled and said, "This is no problem."

"When I make it later, I will tell you some details that need to be paid attention to, and then you will know it, and then follow the way I make it, it is completely possible."

While talking, Won continued to process polyester compounds.

"The first thing I prepared was an organic solution electrolyte: 'propylene carbonate'."

"This is a stable performance, colorless and odorless at normal temperature, or presents a light yellow transparent liquid, soluble in water and carbon tetrachloride."

"It can be used as an excellent medium for high-energy batteries and capacitors in the electronics industry, and can be used as a solvent and plasticizer for polymers in the polymer industry."

"Non-toxic, there is no problem with skin contact and oral administration in a small amount. It is an excellent chemical."

"As for the laboratory preparation method of 'propylene carbonate', it is also very simple, and there are many preparation methods."

"Transesterification method, phosgene method, chloropropanol method, urea alcoholysis method, carbon dioxide and 1, 2. Propylene glycol synthesis method, carbon dioxide and propylene oxide synthesis method can all be synthesized."

"The raw materials I used this time are carbon dioxide and propylene oxide synthesis, which uses zinc fluoride and potassium iodide as catalysts."

"There are two caveats to using this method to synthesize 'propylene carbonate'."

"The first is that propylene oxide is toxic, and you need to wear protective clothing and a gas mask when handling it."

"The second is temperature and air pressure. During the reaction, the maximum temperature must not exceed 160 degrees, and the pressure must not exceed two atmospheres."

"It is easy to manufacture, has high catalytic efficiency and high yield, and is very suitable for industrial production and laboratory production."

While speaking, Won was handling the materials in the glass container.

Control the temperature of the compound in the container by a thermometer, and keep it floating at about 130 degrees.

This is the most suitable temperature for the generation of 'propylene carbonate' with the highest efficiency.

Soon, all the compounds in the bottleneck container have reacted.

The specific performance is exactly how much carbon dioxide will come out as much carbon dioxide is introduced. This is the performance that all the propylene oxide available for reaction in the container has been formed into 'propylene carbonate'.

Judging that this step is very simple, Won quickly separates the container after confirmation, and then separates 'propylene carbonate' from the solution by means of vacuum partial temperature fractionation.

It took more than two hours, and finally harvested a full two liters of yellowish transparent 'propylene carbonate' solution.

Compared with the manufacture of electric propulsion engines, the compound production of 'propylene carbonate' has little difficulty.

Especially for an aging chemical like Won, the visual acuity and the knowledge information in his mind can accurately help him judge the progress of the compound in the container.

There is no difficulty in distinguishing them.

It's like boys distinguishing which Ultraman is, and girls distinguishing lipstick numbers.

Turn off the alcohol lamp, seal the container containing 'propylene carbonate', disassemble the laboratory equipment, clean it, and place it in the tuyere to dry.

Waiting for the time for the container to dry and be reused, Han Yuan picked up the prepared 'propylene carbonate' solution and showed it under the camera in all directions, saying:
"Everyone has just seen clearly, the preparation of 'propylene carbonate' is actually a very easy thing."

"Just follow the steps I just prepared."

While speaking, he poured out some of the solution in the bottle neck container to check the purity and quality.

However, he currently does not have professional inspection equipment such as a gas chromatograph, and can only conduct inspections through the quantitative limit solution configuration method.

Although the accuracy is not as good as the gas chromatograph, it is enough as long as it is within the standard range.

Of course, for the sake of accuracy, Han Yuan did a total of ten sets of experiments.

检测结果分别是97.45%、97.62%、97.22%、98.01%、96.98%。。。。。

After removing a highest value and a lowest value, the detection purity index was flattened at 97.46%.

This purity is enough to be used as an electrolyte for lithium-sulfur batteries and fully meets the standards.

In fact, Won was hardly worried that the test results would not meet the standards.

Although chemically synthesized substances seem complicated and relatively unstable, as long as they follow the prescribed steps and know what each step does, they can basically be produced normally.

Otherwise, if it fails at every turn, the chemical production line will not be established at all.

Moreover, during the experiment, if there is any abnormal phenomenon, an aging employee can basically judge it immediately and carry out investigation and remedy.

But the viewers in the live broadcast room didn't think so. Seeing that the Korean won configured 'propylene carbonate' so easily, they all felt that I could do it myself.

[It looks so simple. 】

【That's it?I can do it too. 】

[Students who can burn distilled water and fry retorts, please stop bragging here, okay? 】

[Seeing the anchor doing this, I remembered a glass bottle that made snow that I made before, it was really simple. 】

[Good guy, everyone is swelled up. 】

[The one upstairs, is it made by adding aqua regia first and then fingers?ヾ(ω`)o]

[It may be to put potassium chloride first, then put white sugar to make snowflakes, or it may be to put water first, and then put sodium metal. 】

[Or put water first, then put 'francium'? 】

[Reminder: Francium, a radioactive element, has a half-life of only 21 minutes and is extremely active. Therefore, its reaction with water is a 'nuclear reaction'. 】

[Nuclear reaction! ! ! ! ! ! ! ! 】

[Hey guys, are you all thinking of blowing up the school? 】

[A warm reminder that is useless, you can't get francium anyway. 】

On the virtual screen, the barrage remained the same, and within 2 minutes it was so crooked that it didn't know where it went.

But Won was interested when he saw the nuclear reaction between the element 'francium' and water.

After thinking about it, he searched in his mind and found knowledge and information related to the radioactive element 'francium'. After reading it, it proved that what this netizen said was indeed true.

The reaction between 'francium' and 'water' is also called the simplest nuclear weapon in this material. Of course, the explosive power is not that great, let's not talk about radioactivity.

Of course, because the radiation period of francium is very short, francium is very rare. According to the calculation of scientists, the content of francium in the earth's crust is about 30g at any time.

It is the second rarest element after 'astatine', not to mention ordinary people, more than 90.00% of the countries can't get this thing.
