~《》~Chapter 949 The school uniform strategy of the big plan

Playing with eggs!

Catherine couldn't help but want to complain.

After working for a long time, the problem still lies with the battery?

After coming back, Catherine really wanted to make the legendary nuclear energy battery. In Catherine’s view, it seems that there is only this thing now that can meet her needs...

"Don't you have to show a killer?"

Catherine had a lot of thoughts in her mind.

In Catherine's mind, in addition to nuclear energy batteries, the best battery Catherine thought of was...Vanadium batteries!

The full name of vanadium battery is all-vanadium redox flow battery, which is a redox battery in which the active material is in a circulating liquid state.

In the beginning, Catherine simply ignored this peculiar battery.

The data is in her head, but as long as it is not a specific data, Catherine can't summarize the data like a smart computer.

But someone in the Golden Dragon Battery Company put forward related ideas, but it made Catherine suddenly think of related things.

Compared with other chemical power sources, vanadium batteries have obvious advantages. The main advantages are as follows:

1. High power: by increasing the number of monolithic batteries and electrode area, the power of vanadium batteries can be increased. In other words, the power can be increased in a brainless way, which is absolutely simple.

2. Large capacity: by arbitrarily increasing the volume of the electrolyte, the power of the vanadium battery can be arbitrarily increased, reaching more than GWh; by increasing the concentration of the electrolyte, the power of the vanadium battery can be doubled.

3. High efficiency: due to the high catalytic activity of the electrode of the vanadium battery, and the positive and negative electrode active materials are stored in the positive and negative electrode electrolyte storage tanks respectively, the self-discharge consumption of the positive and negative electrode active materials and the charge and discharge energy of the vanadium battery are avoided The conversion efficiency is as high as 75%, which is much higher than 45% of lead-acid batteries.

4. Long life: Since the positive and negative active materials of the vanadium battery only exist in the positive and negative electrolytes, there is no phase change common to other batteries during charging and discharging, and the battery can be deeply discharged without damaging the battery, and the battery has a long service life .

Speaking of it, Catherine knew that this was derived from the Guinness World Records, because there is a vanadium battery module that has been running normally for more than 12 years.

In other words, it is impossible for a vanadium battery to become inefficient after two years as a lithium battery, and it will not be as cheating as a lead battery.

5. Fast response speed: the vanadium battery stack is filled with electrolyte and can be started instantly. It only takes 0.02 seconds to switch the charge and discharge state during operation, and the response speed is 1 millisecond.

6. Instantaneous charging: the vanadium battery can be instantly charged by replacing the electrolyte.

7. High safety: The vanadium battery has no potential explosion or fire hazard, even if the positive and negative electrolytes are mixed, there is no danger, but the temperature of the electrolyte rises slightly.

8. Low cost: In addition to ion membranes, vanadium battery components are mostly cheap carbon materials and engineering plastics, with abundant material sources, easy to recycle, no precious metals as electrode catalysts, and low cost.

9. The vanadium battery has a large degree of freedom in site selection, can be fully automated and closed for operation, has no pollution, is simple to maintain and has low operating costs.

Catherine called up her own data from her brain, and these data appeared in Catherine's brain, as if Catherine saw them at the time.

It is indeed a good thing for Catherine to remember such unimportant information.

But... the problem is that although I know this, I don't know what kind of change this event can bring to me in the end and how it will end.

Just before, Catherine felt that she had studied too early, but now Catherine has made a decision: research! Be sure to study!

Regardless of whether it is a fantasy or science fiction thing, as long as you can use it, you can put it in!

Catherine decided to invest 30 million in advance. We are rich now. If we want to study, we will study one that is so vicious!

Of course, vanadium batteries are so good, they are not the same, and there are no defects.

First, the pentavalent vanadium in the cathode liquid of the vanadium battery is prone to precipitate vanadium pentoxide when it is left standing or at a temperature higher than 45 degrees Celsius. The precipitated precipitate blocks the flow channel, coats the carbon felt fiber, and deteriorates the performance of the stack. Until the stack is scrapped, the temperature of the electrolyte can easily exceed 45 degrees Celsius during long-term operation of the stack.

Second, the graphite electrode plate needs to be etched by the cathode solution. If the user operates it properly, the graphite plate can be used for two years. If the user does not operate properly, the graphite plate can be completely etched on a single charge, and the stack can only be scrapped. Under normal use conditions, maintenance is performed by professionals every two months. This high-frequency maintenance is costly and laborious.

In addition, the cost of vanadium batteries is too high, even from the perspective of the 21st century.

From the perspective of environmental protection, vanadium batteries are not environmentally friendly at all. The raw materials used to prepare the electrolyte, the positive electrode precipitation, and the thin layer formed by the leaked positive electrode liquid after air drying all have the same thing, that is, vanadium pentoxide. It is a highly toxic chemical.

Fear of the green organization going into trouble is also the reason for Catherine's hesitation-because if this thing is to be sold, it will definitely be embarrassing.

But as far as Catherine knew, in 2011, electric vehicles with vanadium batteries were launched. Therefore, vanadium batteries should be more reliable than sodium batteries. At least Catherine has only heard of sodium batteries in the laboratory, but actually uses them. But it doesn't work.

...

"Kate, look at you, this is my newly designed dress!"

Lisa looked like a child who had just done something good, and jumped in front of Catherine.

"Um...is this men's clothing?"

Catherine was wearing a similar tights at this time, and then Catherine picked up the dress and found that the dress was compared with herself and found that the style was really similar.

And the clothes have not changed much. The underwear inside is almost exactly the same, that is, a cover is added to the crotch.

The original female cloak was replaced with trousers.

"But Lisa, why do you want to change into long pants? How is the combination of trousers and tights so different?"

Catherine asked strangely.

"Um... because I think boys would prefer pants, right?"

"Lisa, you should understand the history of the Japanese. Their traditional dress is kimono."

Kimono is not only women's clothing, but also men's clothing.

"Men's kimonos are not tight pants like this, but looser ones..."

Catherine explained to Lisa the clothing of men's clothing.

But this kind of clothing does not seem to work.

In Catherine's view, if you can modify the trouser legs, it will be more gentle. Catherine feels that this will make the Japanese feel more pleasing to the eye.

Japanese people always like to add Western culture to Japanese native culture, and even Western fantasy, they also like to force some Japanese elements into it. Without elements, creative elements must be added too!

So in Catherine's view, if foreigners design a school uniform that is quite gentle for Japanese, even if they don't adopt it, they will definitely feel very ghastly in their hearts.

Although the Japanese are not uncomfortable, Catherine also knows that there is such a small attack hidden in the emotions deep in Xiao Su's heart, even in Japan.

If Americans are able to flatter them, they may not respond on the surface, but they will definitely be very sullen in their hearts.

At this time, the sales of their products are definitely better.

Ordinary Japanese men's school uniforms are very monotonous, and Catherine feels that this is one of her opportunities.

Boys’ school uniforms are cross-breasted school uniforms, similar to tunic suits, and 85% of school uniforms are based on dark blue. Summer is a white short-sleeved shirt, and the pants will be replaced with thinner materials.

In addition, there are school uniforms similar to suits. Western-style school uniforms can be divided into suits, shirts, bows or ties. Boys wear checkered trousers or trousers.

There are many types of school uniforms. Almost every country’s school uniform reflects the country’s culture and education to some extent. European and Japanese school uniforms are already distinctive fashions. The school is famous for its strict management of students; Thailand’s school uniforms are known for their sexiness. The skirts of girls’ school uniforms have just passed the thighs, which shows the country’s openness.

But Catherine didn't understand Thailand now, and it was probably not much better there.

In Japan, the uniforms of different schools may differ slightly in details, but this basic design makes the style of Japanese school uniforms unique. Not only are students wearing them, but even after graduation, students are willing to go out in school uniforms. It can be said that school uniforms have become part of Japanese national culture. Japanese animation, movies, and popular music mv all use school uniform elements.

The anime "Beauty. Young. Girl. War. Scholar" that once had the deepest influence on Chinese girls born in the 1980s. Everyone wears a beautiful sailor suit. Iwai Shunji's movie "Love Letter", Fujii Shu and Takashi Kashiwabara's campus I don’t know how many people are moved by love. Even in Japan’s famous love action culture, school uniforms have become the most lethal props for love action actresses.

The fact that the Japanese can develop school uniforms into a kind of culture is actually something after World War II. Japanese school uniforms are set as today’s style. It’s said that they learned from Europe~www.wuxiaspot.com~ In the period of Queen Veroria, sailor suits were worn on children. This trend later spread to European countries until it was taken by Japan in 1879. The adoption of noble schools continues to this day.

Prior to this, Japanese students wore almost all kimonos. At this time, the Japanese school uniforms for boys were more inclined to the costumes of officers, while girls’ costumes were more like ordinary soldiers. This almost exactly confirms the social status quo in Japan that men are superior to women. Nowadays, only a small number of Japanese girls leave home to work after they get married.

Now, Japan's national strength has risen, and they even clamored for "buying the United States" later.

This is the hidden ambition of the Japanese.

At this time, foreigners like Catherine and others made Japanese-style school uniforms to please the Japanese. Whether they will be popular or not, the conclusion is of course ready~

...

Three shifts completed~

The only possibility to break the watch is that we have already died!
