Originally.

Some time ago, I saw that Black Bone's AI robot technology had broken through and created an unprecedented bionic robot 'Zhou Yi', and he still planned to wait for Black Bone to launch the robot and buy one to conduct a special evaluation.

But at this time, the robot is not in sight, and the black bones have got the battery out first, so why do you feel a little out of business?

However, what makes Wei Songbo feel weird is that this battery is not a lithium-ion battery, but a lithium-air battery?

Wei Songbo's first reaction was not to believe it, thinking that the black bones could not be a mistake in the propaganda, right?

As a former top student of Mizuki University, in Wei Songbo's eyes, the words 'lithium empty battery' are a bug in themselves.

In the live broadcast room, the audience saw the promotional poster of 'lithium air battery + second charging technology, let your mobile phone battery be fully charged in 10 seconds', and sent out a full screen of question marks.

“？？？”

"Wow, are all the lithium empty batteries coming out?"

"Are you sure you're right, it's a lithium-air battery, a turtle, a turtle, and a black bone is so good, and the lithium-air battery has been made?"

"Which big guy is popularizing science, what is a lithium-air battery, Meng Xin said he hadn't heard of it. ”

"Damn, is the black bone crazy, fully charge the mobile phone battery in 10 seconds, aren't you afraid of causing an accident if it is charged?"

Wei Songbo glanced at the barrage and said: "If you change companies to advertise such posters, I will definitely not say a word, and immediately start spraying, but the black bones are ...... Given that this company's products have always been reliable, I still put a question mark on it first, and I am not busy making conclusions. ”

An audience member in the live broadcast room said: "Lao Wei, don't you want to evaluate the battery, go test the black bone lithium empty battery to see if they are bragging!"

There were a lot of barrages at the bottom that immediately followed suit.

Wei Songbo coughed lightly: "This and this...... Let's forget about the black bones for now, let's go look elsewhere and come back tomorrow?"

He was still going to Pinsheng to test it at this time, how could he waste time on the black bone side?

However, I don't dare to say it directly.

At this time, an audience suspected of being a local tyrant directly gave him a gift of 10,000 yuan, and said: "Don't talk nonsense, hurry up and test the lithium empty battery, and there will be a reward later." ”

In addition to this audience, other viewers also cleared their accounts and gave Wei Songbo a lot of gifts.

For a while, Wei Songbo felt MMP in his heart, and he didn't dare to say that he wanted to go to the Pinsheng evaluation at this time, otherwise he would expose his stuffing and expose his purpose, which would probably be cool.

Helpless, Wei Songbo could only grit his teeth and walked to the site of the Black Bone Battery Company.

"Let's test the battery of the black bone casually, and then let's leave. ”

Wei Songbo made up his mind that it would be okay to do it perfunctorily, and came to the booth to ask a staff member: "Hello beauty, I want to know something." ”

"Hello. The girl said, "Is there anything I can do to help you?"

"That, that's the case, I'm an evaluation blogger on the Douyin platform, and now I'm running a live broadcast, tens of thousands of people are watching, I saw your promotional poster when I passed by just now, I want to ask, are you really a black bone company?"

"Of course, this is the exhibition venue of the Black Bone Battery Manufacturing Company, a subsidiary of the Black Bone Group. ”

"Is it true that the lithium empty battery is advertised?"

"Yes. ”

"Yes, I'm very curious about this lithium-air battery, so I take the liberty of asking, can I test it on the spot?"

"Of course, you are more than welcome to test our products. The girl pointed to the area behind her and said, "Batteries of various models and sizes are on the shelves."

You can test the battery in any way other than disassembling and destroying it, and then just put the battery back in place. ”

"Okay, thank you. ”

"You're welcome. ”

Testing the battery is a troublesome job, especially the mobile phone battery, which takes a long time.

But since it was decided to evaluate the lithium battery of the black bones, there were still so many viewers watching in the live broadcast room, Wei Songbo could only stiffen his head, and at the same time sent an assistant to inform Pinsheng's people, telling them that they could not go for the time being.

Coming to the shelf area, Wei Songbo walked around and picked up a few batteries of different models and compared them.

Suddenly, people are a little stupid.

"Damn, a 10,000mAh battery, don't tease me......" Wei Songbo looked at the battery capacity mark in his hand, and his eyes widened.

"What's the matter, old Wei?" an audience member heard Wei Songbo's surprise and hurriedly asked.

Wei Songbo looked at the camera, then put a black battery in his hand in front of them, and asked with a smile:

"Ladies and gentlemen, such a small battery, the weight is estimated to be about the same as an egg, guess what, what is the battery capacity marked on it?

10000mAh battery capacity, while the standard voltage is 4.2V!

Lao Tie, who knows a little bit about physics, should know what this means, right?

It's just such a fart big battery, its energy capacity, actually reached 42wh.

My goodness, I'm wet!"

In the live broadcast room, some viewers who know something about mobile phone batteries floated up the barrage.

"A 42Wh battery!! that's it?"

"No, Lao Wei, are you mistaken?"

"The battery capacity of mobile phones on the market today is generally not more than 20wh, right? ”

"I rub, 42wh is actually only the weight of an egg, I remember that an egg does not weigh more than 50g, right?"

"Lao Wei hurriedly weighed the weight of the battery, calculate what the specific energy is!"

Without being reminded by the audience, Wei Songbo had already asked the assistant to take out the small electronic scale he was carrying.

Turning on the electronic scale and zeroing the weight on the scale, Wei Songbo carefully put the black lithium-empty battery on it, and then, the battery weight appeared in the display bit.

35g！

"I'll go, it's only 35 grams!"

"It's a day, Lao Wei, is this title okay, right?

"I see it's wet, a 35-gram battery, and the capacity has reached 42wh??"

"Wouldn't the energy density exceed 1000whkg after a little conversion?"

"It's not just 1000, to be exact, it should be 1200whkg!"

“...... How could it be! fake, right?"

"What are you talking about, I'm confused. ”

"Me too, I don't understand it at all. ”

Wei Songbo took a breath and said in disbelief: "Brothers, according to the capacity marked on this, the energy density of this battery, that is, the specific energy value has reached 1200whkg, turtle, this is unimaginable."

Now the world's most advanced commercial battery, the energy density is only more than 300whkg, and the black bone battery, the energy density is nearly three times.

Do you know what this means? Many friends who don't understand this industry may not have a concept, it doesn't matter, I'll give you a science popularization.

This means that if you replace the battery of your current mobile phone with this battery, it used to run out of power after about ten hours of playing games and watching videos, but now it can be used continuously for 40 hours.

Now the electric vehicles on the market have a range of four or five hundred kilometers, and after replacing this battery, the range can easily exceed 1,000 kilometers.

When the time comes, hehe, all fuel vehicles will have to stand aside, and electric vehicles will be the mainstream in the future.

Now, do you know what this energy-density battery means? It means a new era of energy...... Wait!"

At this point, Wei Songbo suddenly remembered something, and his eyes widened again:

"I remember seeing the advertisement that it says you can fully charge the battery in 10 seconds, right?

If that's the case, it's a blast!

No, no, we have to test it right away!"
