Salty fish learn to play technology

“The 48-hour standby time is second to none in a smartphone.”

“Zhang Shen shouldn’t confuse the smart machine with his old age machine, right?”

“It must be so, domestic elderly machine, charge once standby for a month to understand.”

“Suddenly remembered that classic joke.”

“The horn of a domestic mobile phone is still a loud joke-?”

“Hahaha, I’ve heard this joke.”

“Heard +1”

“Please.”

“Let’s say three people riding the train together and listening to music on their phones together. Soon the fruit machine was the first to run out of power, and it didn’t take long for Samsung’s to run out of power. Then a few hours later, the speaker of the domestic cottage mobile phone was still loud. ”

“6666, vivid and expressive.”

“This joke is so graphic.”

“I can’t imagine that Zhang Shen is so patriotic that he actually uses a domestic cottage machine.”

In the midst of various ridicule in the barrage, Ren Changfei explained with a smile: “48 hours of standby time is already a long time. ”

“It’s a long time? Do you have any misconceptions about long? ”

Ren Changfei, why does this sound strange and a little dirty.

Stunned for a moment, Ren Changfei asked, “It’s really long, Mr. Zhang, what mobile phone do you usually use?” ”

Zhang Wei suddenly took out a mobile phone from his pocket, which was Warwick’s flagship machine.

“Emmm., Mr. Zhang, how long can you usually stand by this phone?”

Ren Changfei said with a wry smile at this time.

In fact, he knows exactly how long his flagship can be on standby.

Compared with the flagship machine of this battery customized for Zhang Wei, it cannot be compared at all, and the daily standby time is only 24 hours.

At this time, Zhang Wei suddenly spoke, “Emmm. This phone can probably be on standby for two weeks normally.” ”

Ren Changfei: “Two weeks, this time…” Wait, how long do you say it can standby? ”

Ren Changfei immediately shouted.

“Two weeks.” Zhang Wei said with a strange look.

“Two weeks? Have you always turned off the phone? ”

Is that number simply good?

Not to mention two weeks, it is impossible for this phone to last for two days.

“God is turning off the machine.”

“Is it really appropriate for you to be so black with your own mobile phone?”

“Why is Lao Ren so cute!”

At this time, Zhang Wei blinked, “How can it be turned off, I have always turned it on.” ”

“So how the hell did you manage to be on standby for two weeks?”

Ren Changfei couldn’t help but ask suspiciously.

“Because I use a battery that I developed myself.”

“Huh?”

At this moment, not only Ren Changfei, but everyone else present froze.

Self-developed batteries? Can you still play like this?

Ren Changfei didn’t know what to say at this time.

The same mobile phone, the battery developed by people can be standby for two weeks, they can only standby for 28 hours, how can this gap be so big?

For a while, Ren Changfei couldn’t help but start doubting life, and after a while he took a deep breath and asked, “Mr. Zhang, how did you do it?” We have made maximum use of mobile phone space, but the capacity of the battery is really limited. ”

Ren Changfei looked at the mobile phone on the table, unable to figure out how Zhang Wei did it.

Not only him, but everyone else present also looked curious.

At present, batteries have always been a bottleneck that restricts industrial development, and it is precisely because of the limited power storage of batteries that electric vehicles cannot be developed. Smartphones also have to be charged frequently.

Hearing Ren Changfei’s question, Zhang Wei said as a matter of course: “Such a large lithium-sulfur battery storage is enough for two days of standby.” ”

“Huh? Lithium-sulfur batteries? Ren Changfei asked confused.

However, some people in the group of high-ranking people at Mizuki University exclaimed.

“Lithium-sulfur batteries? Zhang, sir, have you mastered lithium-sulfur battery technology? ”

0······· Ask for flowers0 ···

When everyone heard this, they immediately saw a gray-haired old man looking at Zhang Wei with an excited expression.

This person is no stranger to many people present, and it is Wang Haijian, the most authoritative expert in organic chemistry.

The direction of his research is how to further improve the performance of batteries, and lithium-sulfur batteries are a topic he has high hopes for.

Zhang Wei was also not modest when he heard this, and nodded directly: “Yes.” ”

Wang Haijian’s eyes suddenly lit up: “Then Mr. Zhang, how did you solve the problem of lithium dendrites?” ”

Lithium dendrite is a serious discharge phenomenon that cannot be avoided when lithium batteries work.

0……

This phenomenon will seriously affect the service life of lithium batteries, it can be said that it is the existence of this problem that will make battery technology not much progress for so many years.

Zhang Wei heard his question and said nonchalantly: “This problem is very easy to solve, through the PDMS material film to improve the air permeability of the anode material, so that the growth of lithium dendrites can be perfectly solved.” ”

Hearing Zhang Wei’s words, Wang Haijian suddenly froze on the spot.

“Is that okay?”

At this moment, he seemed to have suddenly opened a new door to lithium batteries.

Although the others did not understand what the two were talking about, it was not difficult to guess just by looking at Wang Haijian’s expression, which was definitely a very remarkable achievement.

At this time, Wang Haijian muttered to himself: “If this conclusion can really be true, then with this achievement alone, you can win the Adams Silk Prize in Chemistry.” It’s no exaggeration to say that this technology will change the world. ”

Hearing this evaluation, the high-ranking members of the university showed surprised expressions.

The audience in the live broadcast room was even more sluggish.

The “Adams Prize in Chemistry” is also known as the highest prize outside the Nobel Prize in Chemistry, and just through this statement, you can understand the weight of this award.

And Zhang Wei actually casually made a small invention to pocket this level of award, and everyone was shocked at this moment. _
