Automotive Black Technology Chapter 882: : X super molten metal battery, awesome!

www.lnmao.org, the fastest update to the latest chapter of automotive black technology!

Li Fanyu knows that the right one is the best.

No matter from which aspect, making an electric bus is a decision that is very suitable for Zhengxin’s current situation.

In fact, in the previous time and space, BYD started with electric buses. After mastering certain technologies, hybrid models like Tang Song Yuan were launched with electricity as their selling point.

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

Just like when the company officially launched its first mass-produced model, the A4L, Li Fanyu had the same idea - only products that can survive on the market can make Zhengxin go further in the field.

Li Fanyu has always known this truth.

So even though the outside world was making a lot of noise and expressed disappointment with Zhengshin's low-power electric bus, he didn't care at all.

If you rush into the high-end product field without mastering the core technology and manufacturing experience, that would be the Great Leap Forward. In that case, what's the difference from the previous time and space when Hongqi couldn't even make a B-class car and just made a five-million-dollar luxury model?

Li Fanyu doesn’t want to be a salted fish!

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

In fact, it doesn’t even matter what Zhengxin’s first electric car is. What he is most concerned about now is the X molten metal battery technology that is about to be unlocked.

That is the most critical step for whether the electric vehicle plan can be implemented!

As long as you have good enough battery technology, it doesn’t matter what form or category of electric vehicles you have. To some extent, it doesn’t matter.

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

Because he knows the magic of his chairman, and also knows that Li Fanyu often tinkers with new things in the laboratory, the two parts of the X Materials Laboratory and the X Energy Laboratory are located in the industrial base. Li Fanyu’s exclusive venue.

It belongs to the level where entry is prohibited.

In the X Energy Laboratory at this time, Li Fanyu was sitting on a chair, looking through the eyes at the progress bar on the system panel.

The waiting time was excruciating, and every minute seemed extremely long to Li Fanyu.

I don’t know how long I have been waiting.

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

Li Fanyu was ecstatic!

Directly click on the battery technology option that has turned green and yellow, and can’t wait to enter the explanation interface.

[X Super Molten Metal Battery]: A primary liquid metal battery using

Ingredients: The internal liquid is 55% X metal aluminum, 12% conventional magnesium, 15% calcium, accompanied by calcium chloride, to make an alloy in proportions.

Working principle: The alloy forms a metal solution at an operating temperature of 300 degrees Celsius, and uses their different densities and non-miscible characteristics to produce natural stratification. During the discharge process, the upper negative electrode material is oxidized to form free ions, which pass through the molten salt electrolyte in the middle and combine with the positive electrode material. The opposite is true during the charging process.

Production method: Utilize the characteristics of multi-ion electrolyte with lower liquefaction temperature and lower calcium solubility, use 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 a Coulombic efficiency of 100%-115% and an energy efficiency of >80% at an operating temperature of 250 degrees, with no performance degradation after 3000 charge and discharge cycles.

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

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

Li Fan was dumbfounded after seeing this explanation.

MMP!

This performance is a bit abnormal!

It is indeed a battery technology that exceeds the current space-time technology by 150%!

Needless to say, the manufacturing method is simple and the production cost is low. Let’s talk about this performance;

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

What is Coulomb efficiency?

Coulombic efficiency, also called charging efficiency, refers to the ratio of battery discharge capacity to charging capacity during the same cycle. Simply put, it is the percentage between discharge specific capacity and charging specific capacity.

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

In conventional batteries, all the input power is often not used to convert the active material into a charged state, but part of it is consumed. For example, some irreversible side reactions occur due to impurities and battery structure problems.

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

This principle is actually very simple - just like a box of Mengniu cup yogurt.

Fifty ml of yogurt is put in when it is produced, but when you drink it, there must always be a little left.

No matter how much you **** with a straw, you can't **** it all away. Because of the internal structure of cup acid and the coagulation properties of yogurt, there will inevitably be residual consumption.

This is the truth, this is the defect of conventional batteries.

But!

The Coulombic efficiency of X super molten metal battery can reach up to 115%!

What is this concept?

Let’s take a cup of acid as an example!

With fifty milliliters of cup acid, you can **** out fifty-seven milliliters of yogurt!

Are you happy?

Awesome!

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

An energy ratio higher than 80% means that the efficiency of converting electrical energy into kinetic energy is higher.

The loss during the conversion process is only 20%. Compared with ordinary lithium batteries, this efficiency is simply revolutionary!

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

What does cycle charging mean?

It means that a battery is used from fully charged to no longer charged, and then fully charged again. This is called a charging cycle.

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

Generally speaking, one charging cycle is one day.

Under such intensity of use, the lifespan of a good-quality battery is four years—nearly 1,500 days and 1,500 charge cycles!

But please note, this is talking about life span!

The meaning of life span is that after reaching 1,500 charging cycles, this battery will be useless!

However, the performance of the X super molten metal battery clearly shows "no performance degradation after 3,000 charge and discharge cycles!"

In other words, three thousand complete cycles will not affect its performance at all. After three thousand cycles of charging, the performance slowly declined!

So how long is the lifespan?

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

Like a fool who married a beautiful wife, he drooled with a silly smile on his face.

Awesome...

My system!

As for the shortcomings of the operating temperature being too high and the need to use a cooling system, he simply ignored it.

Is that still a problem?

Isn’t it SoEasy to add a water cooling or air cooling system outside the battery system?

Now, there was only one thought left in his mind.

MMP!

This battery is awesome!
