One Thousand Nine Hundred and Forty-Four New Track, New Gameplay!

Brothers, I have opened a new book again: Restarting Life: I can call myself ten years ago. Brothers, help me collect it and give some recommendations!

******************

Geothermal pipes are paved under almost all roads in the factory area, and even under the roads connecting the factory area to the main city.

In this way, this road will definitely be the best to walk in winter.

In addition, the geothermal pipes are also arranged very cleverly. There happens to be a section that passes under the street light pole.

In this way, whenever hot water flows through it, it will create a temperature difference with the surface air.

Once there is a temperature difference, air flow, that is, wind, will naturally occur.

With the wind, this windmill can rotate 24 hours a day.

As a science student, Booth always admired the ingenious idea of ​​​​heat exchange work by other factory designers.

This really considers every detail and maximizes heat recovery.

The most eye-catching thing about the entire factory is that they have a particularly large energy storage station behind the factory area.

Everyone knows that one disadvantage of photovoltaic and wind power is that they are not as stable as thermal power.

In a thermal power plant, you only need to burn the boiler and that's it.

The hot steam generated by the boiler drives the gas turbine to rotate and generate electricity.

If you want to generate more power, burn more coal, generate more steam, pressurize the gas turbine, and that's it.

If you want to generate less electricity, just burn less coal.

Relatively speaking, power generation and current stability are both controllable.

However, photovoltaics and wind power are difficult to control in this regard.

Because it's difficult to control changes in light and wind.

Maybe an hour ago, there was a strong wind here, and then your windmill's power generation efficiency was extremely high, and it might even be 120% effective.

And an hour later, it may be calm here, and there is no wind at all. At this time, your windmill is still generating electricity?

As for light energy, it’s about the same.

In the morning, the wind is sunny and sunny, and your solar panels are operating at full capacity.

But in the afternoon, the clouds are so thick that you may even be unable to see your fingers, and the photoelectric conversion efficiency of the solar panel drops by 75%.

And this thing is not only affected by lighting conditions.

Rain, snow, sand and other weather conditions will affect its power generation efficiency.

Therefore, photovoltaic and wind power are much worse than traditional thermal power in terms of stability and controllability.

This is also the main reason why many power plants are unwilling to connect these two energy sources to the grid.

Because of the instability, if a conversion and rectification factory is specially built for them, the cost will go up.

When the time comes, the cost of electricity per kilowatt hour will be higher than that of thermal power, so it won’t be worthwhile.

Previously, Mr. Booth heard that the country has opened several pilot cities for hydrogen energy in the north, which use wind power and photovoltaic power to produce hydrogen.

However, before producing hydrogen, the current generated by these devices must be rectified.

It is said that a natural cave was used and then sealed to build a gas storage tank.

Then use these waste electricity to drive the blower to pressurize the air supply pipe.

Finally, the airflow is released from the storage tank through the regulating device.

When the airflow comes out, it blows the steam turbine to generate electricity.

In this way, uncontrollable garbage electricity is turned into controllable current.

From the perspective of large-scale use of wind power and photovoltaics, this is the lowest cost and most cost-effective method.

But now it seems that Spark Technology has adopted a completely different approach.

It is said that they built several large storage batteries behind the factory.

And these capacitors are said to be the famous sodium-ion batteries!

In recent times, the concept of sodium-ion batteries has been very popular.

Especially after the number one battery company in China announced some time ago that it has conquered sodium-ion battery technology.

Their stock price is said to have opened higher for several days on the Hong Kong Stock Exchange, and even once made their boss the richest man in the country.

It is said that this technology caused the company's stock price to rise, making the boss's net worth exceed that of Jack Ma.

The domestic self-media also followed all kinds of fancy hype.

During that time, Booth also paid attention to the news about sodium batteries. After all, he was making mobile phones.

Cell phones also use batteries, so he seems to know how sodium batteries are better than lithium batteries.

But then I read a lot of various explanations from big self-media Vs.

But in the end, all I saw were these people talking nonsense, but no one could get to the point about the real mystery of sodium batteries.

They are all a bunch of hotheads.

From that time on, Booth knew that half of the tech self-media influencers he followed were parallel imports.

In fact, most of their explanations on many technologies were copied from certain websites, and some of them even modified the copy themselves.

Some of them didn't change at all, they just copied them mechanically.

In the end, Mr. Booth had no choice but to consult several experts. These real technical experts finally explained the problem to him clearly.

Why was lithium chosen as a breakthrough for the development of the battery industry?

This is because this element is very reactive. Hydrogen and lithium at the front of the periodic table are the two most reactive elements.

It is also the most suitable element for making batteries.

However, people have spent a lot of money on hydrogen before, because this element is very difficult to store and transport.

Therefore, this element cannot be promoted and used on a large scale until special materials are available.

But lithium batteries are relatively safer.

However, although lithium batteries are easy to use, there are still disputes, such as the ternary lithium solution led by LG in southern China, and the lithium iron phosphate battery insisted on by domestic BYD.

The advantages of ternary lithium batteries are high energy density and long cruising range.

However, the problems of this kind of battery are also very prominent, such as easy leakage, very dangerous, and poor discharge effect in winter.

Although the energy density of the lithium iron phosphate battery that BYD insists on cannot be as high as that of ternary lithium, the victory lies in the fact that after adopting the new design scheme, the battery safety has been greatly improved.

And the performance in winter is slightly better than that of ternary lithium.

But no matter which solution is adopted, if we mainly promote lithium batteries, we will face a problem, and that is the high cost.

Why is our country now mainly promoting electric vehicle technology to replace fuel vehicles?

It's because we need to import a large amount of oil every year, and the route we need to take happens to be very dangerous.

To promote electric vehicles, it is necessary to produce a large number of lithium batteries.

As for the ternary lithium in lithium batteries, it is impossible for us to promote it.

Even though this kind of battery has high energy density, the problem is that it still requires nickel and cobalt.

Both elements are scarce in my country. Cobalt is mainly produced in Congo and nickel is produced in Indonesia.

Our domestic reserves are very small, so there are relatively more lithium ores, but they are all lithium ores with high mining costs.

But at least we still have it in our country, so we won’t be stuck.

But the problem is that even so, with the popularity of the concept of electric vehicles in recent years, the price of global lithium ore has doubled several times.

Therefore, our domestic battery manufacturers are still looking for a more reasonable alternative to develop new models of batteries.

This is the background of the birth of sodium batteries!

Because, presumably like lithium ore, sodium is too abundant.

Not to mention the salt mines all over the country, we can extract a lot of sodium from seawater alone.

The activity of sodium is much worse than that of lithium.

Although it can be made into a battery, the energy density of this battery is about half lower than that of lithium batteries of the same volume.

So the energy density alone is a death sentence for sodium batteries.

Because although the cost of this thing is very cheap, the question is why do you produce it?

When installed on an electric vehicle, the energy density is low and the cruising range is not far. Who is willing to pay for such an electric vehicle?

Unless it is a large bus, it has a lot of space and can be equipped with many batteries.

However, our country is vigorously promoting photovoltaics recently, and photovoltaics are in urgent need of high-energy energy storage equipment.

In this special usage scenario, this sodium battery can come in handy.

Not to mention the wind power and photovoltaic energy conversion stations supporting the hydrogen energy pilot cities in the north.

Where the original physical solution was used.

It means to first convert the electricity generated by photovoltaics and wind power into physical energy, and then convert the physical energy into electrical energy.

This requires two conversions, so a lot of losses are bound to occur in the middle.

Someone has done calculations, and no matter how good the connection is, at least 30 to 40% of the electrical energy must be taken advantage of during these two conversions.

Sometimes there is a problem with the equipment, the connection is not good, and even 50% of the energy consumption is reduced.

So it would be great if there was a large-volume supercapacitor that could directly store electrical energy.

It's not like the above have never thought of this method in the past, such as lithium batteries removed from those used electric vehicles that emit exhaust gas, etc.

But the capacity of those batteries is really a drop in the bucket.

Moreover, they are all small battery packs, and it is very troublesome to manage them by reconnecting them in parallel and in series.

It is better to create a large battery from scratch to store electricity, but the problem is that the cost of manufacturing a large lithium battery is very high.

Especially now that the price of lithium ore is rising three times a day.

At this time, with the birth of sodium batteries, the strategic importance of this thing was reflected.

First of all, because there is too much sodium stored on the earth, the price is incredibly cheap.

The current price of a ton of lithium battery materials is US$15,000, while the same ton of sodium-ion battery materials is only US$150!

In other words, the cost of sodium batteries is only one percent of that of lithium batteries!

In terms of energy density, although sodium batteries are only about 40% to half of lithium batteries, they are about double that of nickel-metal hydride batteries of the same volume.

And when it comes to the number of charges and discharges, as well as the discharge performance in winter, they are much better than nickel-metal hydride batteries and lead-acid batteries.

Therefore, although sodium batteries are not suitable for use as power batteries.

But it is enough to make an energy station and a large capacitor device!

Compared with lithium batteries, sodium batteries are a completely different track and another method of play!
