Li Fanyu knows that the right one is the best. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

In any way, making an electric bus is a decision that is very suitable for the current situation of Zhengxin.

In fact, in the previous time and space, BYD started as an electric bus. After mastering a certain amount of technology, a hybrid model like Tang, Song and Yuan was launched, which used electricity as a selling point.

For the field of electric vehicles, Zhengxin is still in the exploration stage.

And just like when the company officially launched the first production model A4L, Li Fanyu's idea is the same - only products that can survive in the market can make Zhengxin go further in the field.

Li Fanyu has always been very clear about this truth.

So although the outside world was noisy, saying that he was disappointed with Zhengxin's LOW bus and electric car, he didn't care at all.

If you don't master the core technology and manufacturing experience, you will rashly enter the field of high-end products, which is the Great Leap Forward. In that case, what is the difference between Hongqi and the previous time and space when Hongqi couldn't even make a B-class car, so he directly made a luxury model of five million?

Li Fan is foolish and doesn't want to be a salted fish!

So one step at a time, in his opinion, is the best choice.

In fact, it doesn't even matter what Zhengxin's first electric car was. The only thing he is most concerned about now is the X molten metal battery technology, which is about to be unlocked.

That is the most critical step in whether the electric vehicle plan can be realized!

As long as the battery technology is good enough, it doesn't matter what form or type of electric vehicle it is.

So on the fifth day of unlocking the technology, he came to the energy laboratory in the industrial base early.

Because he knows the magic of his own chairman, and also knows that Li Fanyu often tinkers with new games in the laboratory, the two parts of the X material laboratory and the X energy laboratory are Li Fanyu's exclusive venues in the industrial base.

It belongs to the level of the prohibition.

At this time, in the X energy laboratory, Li Fanyu sat on a chair and looked at the progress bar on the system panel like autumn water.

The waiting time is torturous, and every minute is incomparably long in Li Fanyu's opinion.

I don't know how long I waited.

Finally, after a crisp system prompt, the progress bar on the spatial system panel jumped to 100 percent!

Li Fanyu was ecstatic!

Directly click on the battery technology option that has become green and yellow, and I can't wait to enter the description interface.

[X Super Molten Metal Battery]: A primary liquid metal battery with X technology, its positive and negative electrodes and electrolyte are both liquid, and no solid materials are required except for the battery frame.

Composition: The internal liquid is X metal aluminum 55%, conventional magnesium 12%, calcium 15%, accompanied by calcium chloride, alloyed in proportion.

Working principle: The alloy forms a metal solution at an operating temperature of 300 degrees Celsius, and uses its different densities and immiscible properties to produce natural delamination. During the discharge process, the upper layer of the anode material oxidizes to form free ions, which pass through the molten salt electrolyte located in the middle and combine with the cathode material, while the charging process is reversed.

Production method: The multi-ion electrolyte has the characteristics of lower liquefaction temperature and lower calcium solubility, with calcium magnesium alloy as the negative electrode, calcium chloride as the electrolyte, and X metal aluminum as the positive electrode.

Characteristics: X molten metal battery has 100%-115% coulombic efficiency and >80% energy efficiency at an operating temperature of 250 degrees, and there is no degradation in performance under 3000 charge-discharge cycles.

Advantages: Magnesium ore and calcium ore in nature almost exist at the same time and are difficult to separate, and the calcium magnesium electrode does not need to separate calcium and magnesium, which can further reduce production costs.

Disadvantages: The working temperature is high, and an outer cooling device needs to be installed when applied to the product to avoid spontaneous combustion.

Seeing such an explanation, Li Fan was dumbfounded,

MMP!

This performance is a bit perverted, wow!

It is worthy of exceeding 15% of the battery technology of the current space-time technology!

The production and manufacturing method is simple, and the production cost is low, needless to say, let's talk about this performance;

What is the concept of 100%-115% coulombic efficiency and energy efficiency greater than 80%?

What is Coulomb efficiency?

Coulomb efficiency, also known as charging efficiency, refers to the ratio of the discharge capacity of the battery to the charging capacity during the same cycle. In simple terms, it is the percentage between the discharge specific capacity and the charge specific capacity.

To put it more simply, it is the ratio between the electricity charged in and the electricity discharged!

In conventional batteries, because the input power is often not fully used to convert the active substance into a charging state, some of it is consumed, for example, due to impurities and battery structure problems, some irreversible side reactions occur.

Therefore, the coulombic efficiency of conventional batteries often does not reach 100%, or even 90%.

This truth is actually very simple - it is like a box of Mengniu cup yogurt.

Fifty millilitres of yogurt are put in when you give birth, but when you drink it, you always have a little leftover.

No matter how much you use a straw, you can't suck it all clean. Because of the internal structure of the cup acid and the coagulating properties of the yogurt, it is determined that there will inevitably be residual consumption.

That's it, that's the flaw of conventional batteries.

But!

The Coulombic efficiency of the X Super Molten Metal Battery can reach up to 115%!

What is this concept?

Let's take a glass of sour as an example!

With 50 milliliters of sour, you can suck out 57 milliliters of yogurt!

Cool?

Absolutely damn!

Rush in a hundred units of electricity, and it will give you one hundred and fifteen units of electricity. This means that inside this X super molten metal battery, a part of the electrical energy can be generated by itself!

And an energy ratio above 80 percent means that electrical energy is converted into kinetic energy more efficiently.

The loss in the conversion process is only 20%, which is revolutionary compared to ordinary lithium batteries!

In addition to these two, there is no performance degradation after 3,000 cycles of charging, which makes Li Fanyu feel as comfortable as eating a bite of ginseng fruit.

What does cyclic charging mean?

It is a battery that is used from full charge to no charge, and then fully charged, which is called a cycle of charging.

Take the most commonly used mobile phone batteries as an example!

Generally speaking, one cycle of charging is considered a day's time.

Under such an intensity of use, the life of a good quality battery is four years - nearly 1,500 days, 1,500 cycle charges!

But be warned, it's about longevity!

The meaning of life is that after reaching 1,500 cycle charging cycles, this battery is wasted!

However, the performance of the X super molten metal battery clearly shows that "there is no degradation in performance after 3000 charge-discharge cycles!"

That is, three thousand complete cycles cannot affect its performance in the slightest. After 3,000 charging cycles, the performance slowly decreases!

So how long is the lifespan of the special?

Seeing these performances, Li Fanyu's expression was wonderful.

He was like a fool who married a beautiful daughter-in-law, and he left saliva with a smirk on his face.

Awesome......

My system!

As for the shortcomings of what the working temperature is too high and needs to be used with the cooling system, he selectively ignored it.

Is that still a problem?

Isn't it SoEasy to add a water-cooled or air-cooled system to the battery system?

Now, he had one thought left in his head.

MMP！

Awesome this battery!
