So at this time, the people all raised their hands in an uproar, hoping to be lucky enough to get a chance to answer, and then show their faces in front of the whole country.

In this regard, the presidents of Pingguo, Sanxing, Moto Luola, Exxon Meifu, Tongyong Automobile, Fengtian Automobile, Benzene Automobile and other companies at the scene were naturally extremely ugly.

At this time, Watanabe Showazu, the president of Fengtian Company, already showed a panicked look on his face, because he found that the current sodium-ion batteries alone actually had the conditions to make electric vehicles.

Because the energy density of 150wh/kg is actually not low, Watanabe Showa at this time did not have experience and knowledge from the future.

But he also knows that with the current energy density, he can actually build an electric car that can travel 400 kilometers!

Of course, the premise of this electric car is not to turn on the air conditioner, and not to carry out additional power consumption!

But even so, an electric car that can travel 400 kilometers is not good news for their Fengtian car.

Because let alone 400 kilometers, even if they can drive 200 kilometers, it will be a huge impact for their Fengtian car!

200 kilometers can have an impact on their Fengtian car, and the impact of 400 kilometers on them is no less than a huge disaster, a disaster that may destroy them at any time!

In this regard, if Lin Xuan knew the thoughts of Watanabe Showa, the president of Fengtian Company, then he would nod his head lightly in approval, because the energy density of 150wh/kg is actually very high.

The energy density of the blade battery that can make BYD Automobile defeat the invincible opponent in the world in the future is actually not as good as the energy density of the sodium-ion battery at this time!

Because the energy density of the blade battery in later generations is only 140wh/kg, and the energy density of the sodium-ion battery reaches 150wh/kg at this time, which is 10wh/kg higher than the energy density of the blade battery!

As for the life, the life of the sodium ion produced by Hantang Technology has reached 5,000 charge-discharge cycles, which is far more than 3,000 charge-discharge cycles, after all, the life of the blade battery is only more than 3,000 charge-discharge cycles.

It can be said that the sodium-ion battery produced by Hantang Technology completely crushed their blade lithium iron phosphate battery!

And although their blade battery is famous, the blade battery is essentially a lithium iron phosphate battery, and the energy density is very low.

Its success is only due to structural innovations that allow them to plug more batteries in the same area and ultimately run farther.

At this time, Hantang Technology can also manufacture blade sodium-ion batteries, which can borrow the advanced architecture of blade batteries and plug larger capacity with a smaller volume.

In the end, Hantang Technology's electric vehicles may be able to equip conventional cars for 500 kilometers, and further squeeze the area structure, and finally achieve the horror of seven or eight hundred kilometers!

So if Lin Xuan knew the thoughts of Watanabe Showa, the president of Fengtian Automobile Company, then he would agree very much.

However, just using sodium-ion batteries to make an electric car is not enough to satisfy Lin Xuan, because he can run seven or eight hundred kilometers, and that is without turning on the air conditioner and other loads.

Once the load such as the air conditioner is turned on, the mileage will plummet, which is why the electric car in later generations has the nickname of "electric dad", in fact, there is no way.

Because it is a common situation for electric vehicles to be falsely marked in later generations, the target is 400 kilometers, but in fact there can only be 350 kilometers.

And in these 350 kilometers, twenty or thirty kilometers should be set aside to find charging piles to charge, just in case of rescue such as crawling.

Therefore, only about 300 kilometers can actually be used.

During these 300 kilometers, once people turn on the air conditioning, the range will be further attenuated from the 300 kilometers.

In this case, 300 kilometers can actually travel 200 kilometers, which is already a good thing.

Therefore, future generations of electric vehicle owners generally have range anxiety, even if the 400-kilometer electric car goes far away, they will be worried that they will not be able to return home, and they are afraid that they will not be able to find the charging pile outside!

Therefore, only 400 kilometers or even 500 kilometers cannot reach the requirements of Hantang Technology!

Therefore, sodium-ion batteries can only be used for low-end and not high-end, and the mid-to-high-end of Hantang Technology must at least start at 1000 kilometers and cap at 1500 kilometers!

However, if the super fast charging station is built more completely, it is better than that of later generations, and it can reach the level of hundreds of thousands of super fast charging stations across the country.

Even if it is an electric vehicle with a mileage of only 400 kilometers, the anxiety will be attenuated a lot, after all, as long as you think about it, it can be solved in fifteen minutes or half an hour, and it can be charged all over the country.

Then the range anxiety will decay, and then people will be able to boldly turn on the air conditioner, and they will not have to worry about not being able to return home all day.

However, these are all things in the future, and now Lin Xuan's goal is to develop all-solid-state lithium batteries, and he wants to directly use all-solid-state lithium batteries to manufacture electric vehicles.

The energy density of sodium-ion batteries is too low, and the upper limit of using sodium-ion batteries to make electric vehicles is there, so Lin Xuan wants to directly use all-solid-state lithium batteries to manufacture mid-to-high-end electric vehicles in one step!

The gaze returns to the scene.

In the midst of the ugly faces of the presidents of major companies, Lin Xuan casually pointed to a lucky guest at this time, which was a creamy student with glasses and fair skin.

"Thank you!"

The cream student who took the microphone bent down to thank the staff member, and then said nervously under the gaze of hundreds of high-definition cameras:

"I have several anxieties about two-wheeled electric vehicles, the biggest of which is range anxiety, but this has been solved, and the second anxiety is safety or anti-theft."

Hearing the words of the cream student, the people on the scene nodded one after another.

Indeed, in this era of economic underdevelopment, there are many thieves.

In the future, thieves will be reduced because cameras are installed on the street and even in many people's homes, and thieves have to know if there are cameras when they go to steal, and you need to imagine the consequences of being caught, so there are very few thieves in later generations.

But in this day and age, there are not many cameras, and in those frontier cities with good economic development, there will be many cameras on prosperous streets and even at home.

However, the general situation across the country is that there are few cameras, in this case, there are many thieves who like to steal trams or directly steal batteries, so the anti-theft security of electric vehicles is a headache for many car owners.

In this regard, Lin Xuan nodded lightly, and then said with a smile:

"Is the electric car anti-theft and safe? We are well prepared in this regard. ”

Hearing Lin Xuan's words, the cream student's eyes suddenly lit up, and then he looked at Lin Xuan with curiosity on his face, waiting for Lin Xuan's words.

At the same time, the others also looked at Lin Xuan excitedly, very curious about what reassuring technical selling points of Hantang Technology's two-wheeled pedal electric vehicles in terms of safety and anti-theft.
