Metropolis: From Heavy Locomotive to Industrial Overlord

Chapter 252 Revolutionary technology! Shocked the audience (seventh, please subscribe)

The appearance and interior of the Feiyue F-one are quite stunning and luxurious.

They are all brand new design languages ​​and layouts.

Give people a bright spot!

It breaks the traditional automobile pattern and gives people the impression that it is quite eye-catching.

However, the Feiyue F-one does not focus on the appearance and interior, but two functions of the king, that is, the graphene battery and L5 level autopilot technology.

Because these two technologies are unique.

Appearance and interior, other car brands now can do it.

Su Qin briefly introduced the appearance and interior of the Feiyue F-one, and then he said: “The biggest obstacle for new energy vehicles now is mileage anxiety!”

All along, “mileage anxiety” has been regarded as one of the biggest problems hindering consumers from purchasing new energy vehicles.

The same is true for new energy vehicles. The battery is like the dry food of a new energy vehicle. How far the vehicle can run depends on how long the battery can last.

However, because of the limited body volume and the battery itself, it is best for the battery to be small, light and durable.

For all new energy automobile companies, the battery is precisely the biggest problem.

The cruising range of electric vehicles can be regarded as a pain in the hearts of all car owners, even if they are already experienced drivers, they cannot avoid the trouble of mileage anxiety.

Su Qin continued: “If you want to solve the mileage anxiety, you must increase the cruising range and continue to reduce the cost of electric vehicles. This has become the two major challenges facing the domestic electric vehicle industry.”

“The key to solving these two problems lies in the materials used in the power battery. The higher the energy density of the material, the more electricity can be stored, and the longer the range of the electric vehicle, and the lower the cost. .”

“Currently, Tesla produced in Country M uses nickel-cobalt-aluminum ternary materials, with an energy density of about 230 watt-hours per kilogram. At present, more than 90% of domestic electric vehicles use lithium iron phosphate materials, which have the highest energy density. It can only reach 140wh/kg.”

“For example, an electric car needs to have a cruising range of 400 kilometers, using lithium iron phosphate materials, about 600 kilograms of batteries, and using Tesla’s ternary material batteries, about 400 kilograms.”

“The problem with low battery energy density is that in order to pursue a longer cruising range, more batteries must be installed, and additional batteries will increase the weight of the vehicle body, increase power consumption during driving, and increase the cost of use. ”

“There is also a problem, and that is the material that can be charged quickly.”

“If a battery material has a high-quality and light range, but it takes more than ten hours to charge a battery, isn’t that nonsense? It would cost you overnight to run a high-speed charge in the service area. Obviously, this material is also unrealistic. ”

This is indeed the problem.

If it takes too long to charge once, it is unrealistic.

It would be best if you can use a battery with fast charging, light weight, and high range.

This is also a problem that major new energy sources have been considering, so a variety of batteries have appeared, such as blade batteries, lithium batteries, and so on.

But these have not made a qualitative change in mileage anxiety.

Therefore, mileage anxiety is still the biggest problem.

All the people present and the audience in the live broadcast room listened carefully to Su Qin’s words.

Su Qin analyzed the status quo of new energy vehicles. Obviously, he has to do his homework, not just bragging.

“So if we want to solve the mileage anxiety, it is to find a kind of raw material that can not only charge quickly, but also have a high cruising range?”

“Yes, that’s a graphene battery!”

“Graphene, I believe you have also heard of it, this is a new industrial material in the 21st century, a new revolutionary material!”

Graphene has excellent optical, electrical, and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery. It is considered a revolutionary material in the future.

Even if everyone in the room didn’t understand, they knew the term graphene.

In fact, graphene originally exists in nature, but it is difficult to peel off a single-layer structure. Layers of graphene are stacked to form graphite, and 1 mm thick graphite contains about 3 million layers of graphene.

A lightly stroked pencil on the paper may leave traces of several layers or even just one layer of graphene.

Everyone knows that graphene is good, but there is no real application of graphene to new energy vehicles.. …..

“I believe you have heard an advertisement line, charge for two minutes and talk for two hours.”

“Our first car, the Leap F-one, uses graphene batteries, which can be charged for 10 minutes and have a battery life of 1,000 kilometers!”

“We know that the charging and discharging process of a battery is actually a process in which cations are “embedded” and “detached” in the electrode. Therefore, if there are more holes in the electrode material, the process will proceed more quickly. From a perspective, it shows that the faster the battery charges and discharges.”

“The microstructure of graphene is a network structure composed of carbon atoms with sufficient pores. It is undoubtedly a very ideal electrode material.”

“According to research by researchers from Rensselaer Polytechnic Institute: using graphene as the anode material of the battery, its charge and discharge speed will exceed 10 times that of lithium-ion batteries!”

“So in other words, the charging speed of using graphene batteries is very fast. It can be charged for ten minutes and has a battery life of 1,000 kilometers!”

Su Qin talked freely and introduced the power of graphene batteries.

Graphene battery is a characteristic technology of Feiyue F-one.

At the same time, the weight of graphene is relatively light, and a lot of graphene is needed to release a very powerful electric energy, because the capacity of graphene is very large!

It’s crazy to charge for 8 minutes and endure a thousand kilometers!

This 3.8 is not slanderous by Su Qin.

Everyone here knows, because there was a previous report that Graphenano cooperated with the University of Cordoba in Spain to develop the first graphene polymer battery, which has three times the power storage capacity of the best product on the market, and uses this battery to provide electricity. The electric vehicle can travel up to 1,000 kilometers, and its charging time is less than 8 minutes.

Graphenano was unable to mass-produce and commercialize it, but Feiyue Group and Su Qin did it.

This shocked everyone present.

Whether it’s the live online big V, car critics, media reporters, or the viewers and netizens in the live broadcast room, they are all shocked.

In an uproar!
