Of course, the sodium-ion battery is also divided into grades, and the sodium-ion batteries used in our BYD electric vehicles are all from Hantang Technology.

The sodium-ion battery of Daxia Petrochemical Company will not be used, after all, the sodium-ion battery life of Hantang Technology is longer, and the energy density and other comprehensive performance are higher.

And because of our relationship with Hantang Technology, our procurement costs are also a little lower."

The beautiful reporter nodded slightly, but soon she asked the next crucial question:

"Mr. Wong Tai Fook, the batteries used to make electric vehicles now are nothing more than all-solid-state lithium batteries and ternary polymer lithium batteries.

Among them, none of the two batteries had an energy density of less than 200h/kg.

Although the sodium-ion battery of Hantang Technology is cheap, the energy density of the sodium-ion battery is only 155h/kg.

Is this energy density too low? Wouldn't the range of an electric car using sodium-ion batteries be too low?"

Hearing this beautiful reporter's question, Wang Dafu's eyes froze, and he secretly said in his heart, "It's finally here."

Before accepting this interview, Wang Dafu knew that this beautiful reporter would definitely ask this sentence.

Wang Dafu didn't feel panicked or worried about this, and even didn't dare to face it, because he was ready, so Wang Dafu smiled and said:

"You don't have to worry about the low energy density of sodium-ion batteries, because our electric vehicles with sodium-ion batteries can achieve a range of three or four hundred kilometers or even six or seven hundred kilometers!"

"Huh?"

The beautiful reporter showed a curious gaze and looked at Wang Dafu, the president of Beatty, with a puzzled expression.

The energy density of ternary polymer lithium batteries is as high as 225h/kg, which is equivalent to half of the ternary polymer batteries of Hantang Technology.

At this time, the energy density of Hantang Technology's sodium-ion battery is only 155h/kg, but in this case, Wang Dafu, the president of Villadi, said that he could do three or four hundred kilometers, which is also the default of the beautiful reporter.

After all, theoretically speaking, squeezing can indeed do this, but at this time, Wang Dafu said that Biadi's electric car can do six or seven hundred kilometers, which is surprising.

In this regard, Wang Dafu smiled and said:

"The reason for this is actually very simple, because a week ago, Mr. Lin Xuan had already pointed out the trick of how to make the sodium-ion battery plug with more power and finally run farther!"

"Mr. Lin Xuan? Can the king always say that?"

The beautiful reporter's eyes lit up, but she didn't expect Lin Xuan to make a move in this matter.

"It's not a secret, anyway, Hantang Technology has already registered relevant patents for a long time, but it hasn't launched related products to the market yet, so let's talk about it."

[The problem of slow update of new chapters has finally been solved in the ability to change the source, here download huann.change the source, and view the latest chapters of this book on multiple sites at the same time. 】

The light in the eyes of the beautiful reporter who heard the words became bigger and bigger, and the reporter who was in charge of recording the video with the camera on the side also hurriedly aimed the camera firmly at Wang Dafu.

In this regard, Wang Dafu smiled and unveiled the mystery.

"The solution given by Mr. Lin Xuan is to use the blade battery solution!"

"Blade battery?"

….

Hearing the name blade battery, the beautiful reporter looked confused, not knowing what it was.

But just listening to the name of this blade battery, this blade battery seems to be a little unusual.

So at this time, the curiosity in the eyes of the beautiful reporter not only did not dissipate, but became bigger and bigger, and the beautiful reporter at this time was very curious about the blade battery.

Don't know what kind of battery a blade battery is, it's a brand new battery? Can it compete with all-solid-state lithium batteries and ternary polymer batteries?

In this way, when there was a strong curiosity in the eyes of the beautiful reporter, Mr. Wang of Biadi did not live up to the expectations of the beautiful reporter, and slowly explained what a blade battery is.

"The essence of the blade battery is also

It's a sodium-ion battery."

Wang Dafu's first sentence made the beautiful reporter slightly stunned, with a hint of loss in her eyes.

The beautiful reporter also thought that the blade battery was a new battery, one that could compete with ternary polymer lithium batteries and all-solid-state lithium batteries.

But I didn't expect that the essence of this so-called blade battery is still a sodium-ion battery, how can the beautiful reporter who learned this result not be disappointed in her heart?

But without waiting for this beautiful reporter to be disappointed, Wang Dafu did not stop his words at this time, only to see Wang Dafu then speak:

"Blade batteries don't have a substantial improvement in energy density, but they have changed drastically compared to ordinary batteries.

This beautiful reporter, have you ever seen a sodium-ion battery with a single cell?"

Hearing Wang Dafu's words, the beautiful reporter was slightly stunned, and then opened her mouth to answer the news she knew:

"Naturally, I have seen sodium-ion batteries with a single cell, and it is said that there are several specifications of sodium-ion batteries with a single cell, and they are No. 3 battery specifications, No. 5 battery specifications, and No. 7 battery specifications.

In addition, it is said that there are 18650 specifications, 21700 specifications, and Hantang two-wheeled electric vehicles are said to use multiple 21700 cells to form a whole battery pack, and this battery pack is called a battery module."

Wang Dafu, who heard this, nodded lightly, and then smiled and praised:

"Your knowledge is good, but it's not detailed enough, and there are actually other specifications at the moment, but the output of those specifications is not big, so it's not too much."

The beautiful reporter who was praised suddenly had a happy smile on her face, and when she saw this, Wang Dafu continued to smile and said:

"Now, whether it is a Hantang two-wheeled electric vehicle or other electric motorcycles, their batteries are essentially battery modules composed of multiple 21,700 cells or 18,650 cells.

And their structures are almost all cylindrical, in which you can imagine a cylindrical thing when they are side by side.

Do they take up a lot of space? Isn't almost half of the volume wasted, and if the battery is crammed into it, will it be able to last longer?"

Hearing Wang Dafu's words, the beautiful reporter already understood what a blade battery was, so she asked excitedly:

"I may understand what a blade battery is, and this so-called blade battery should be like stacking bricks, bricks on top of each other.

Minimize wasted space and end up plugging in more power in the same area!"

Hearing this, Wang Dafu nodded with a smile, and smiled at the words of the beautiful reporter:

"That's right, but instead of bricks, we stacked 9 batteries about 1.3 thick, 1.3 wide, and about 9 long!"

"I see, this is really a genius idea, after such a structural transformation, although the essence of energy density has not improved.

But when it is actually used, it is equivalent to nearly doubling the energy density of the battery, this is really a genius-like idea, a genius-like idea, it can only be said that Lin Xuan is worthy of Lin Xuan, and he actually came up with such a good solution.
