Wei Zhaosheng said and walked to the front of the first trolley.

He lifted the red cloth from the trolley.

There are two Kirin mobile phones and three other brands of mobile phones on the trolley.

In addition, there is a portable infrared thermometer.

That’s right, the thermometer is not a thermometer gun.

At this time, it was not possible to create a temperature measuring instrument as convenient as that of later generations.

The cameraman walked onto the stage carrying the camera.

“Two of these five mobile phones are from Kirin Group. One uses ordinary cobalt-free lithium batteries and the other uses graphene batteries.

The batteries for the other three mobile phones come from batteries from three battery partners.

We now start to detect the temperature of their mobile phones while charging." After speaking, Wei Zhaosheng picked up the portable temperature measuring instrument.

After speaking, the staff began to take the mobile phone out of the box, and the audience could see every step clearly.

These mobile phones are all brand new mobile phones.

After dismantling the mobile phone, the staff connected their charger to the power strip.

"Have you noticed that one of the chargers is particularly large?"

"This charger should be a fast charging charger."

"Ordinary chargers only have 5A. This fast charging voltage is higher and the size is larger, which is normal."

"I guess this charger is not cheap, and the phone as a whole is much more expensive."

"I think it doesn't matter if it's more expensive. As long as it charges quickly, I can still accept it."

"I think so too. As long as it charges quickly, it doesn't matter if it's more expensive. I make hundreds of calls every day and it's annoying to have to keep plugging my phone into the charger."

"The big brother upstairs is so awesome that he has to answer hundreds of phone calls a day."

...

At this time, the staff has connected all the chargers to the power strips.

Because graphene batteries charge relatively quickly, they took the lead in testing graphene battery mobile phones.

The entire charging process takes ten minutes.

The audience and netizens at the scene can see it through the live broadcast.

The temperature of the graphene battery does not exceed 35 degrees even when charging.

"I believe everyone has seen the entire charging process just now. Even when the new graphene battery is being charged, its overall temperature will not exceed 35 degrees.

Its safety when charging is higher than everyone thinks.

All this is thanks to graphene, a new material.

Everyone knows that graphene is a superconducting material that can allow electric ions to pass through quickly..." Wei Zhaosheng retold the basic battery technology to the audience.

The elders present all knew a little bit about the basics of lithium batteries, so it sounded very boring.

But the audience in the live broadcast room listened with gusto.

New knowledge 1?(﹒??﹒?)?

"It's precisely because graphene allows electric ions to pass through other materials quickly.

This slows down the inertia produced inside the lithium battery, which also makes the life of our graphene battery twice as long as that of traditional batteries.

The new graphene battery can be recharged up to 4,000 times.

In other words, your mobile phone may have been obsolete, but the graphene battery can still be used normally." Wei Zhaosheng introduced.

The audience in the live broadcast room was in an uproar when they heard this number.

It's really awesome.

This graphene battery is so durable that even if it is twice as expensive, it is still very cost-effective.

“Here I have to introduce to you another technology of Kirin battery, because fast charging cannot be achieved without this technology.

This technology is the third-generation semiconductor gallium nitride chip developed by Kirin Group.

Gallium nitride..." Wei Zhaosheng began to introduce it again.

After hearing Wei Zhaosheng's introduction, netizens started talking again.

"What are third-generation semiconductors?"

“The development of the semiconductor industry has gone through three stages so far. The first generation of semiconductor materials is represented by silicon;

The second-generation semiconductor material gallium arsenide has also been widely used;

The third generation of semiconductor materials, represented by wide bandgaps such as gallium nitride, silicon carbide, zinc oxide, aluminum oxide, and diamond, have significant performance advantages over the previous two generations of products."

“The Kirin Group is awesome. I didn’t expect Kirin to have mastered gallium nitride technology. You must know that this technology is still under research abroad.

Kirin Group’s technology is at least one era ahead of foreign countries.”

"Kilin Group has too many black technologies and they are so awesome."

"Now those foreigners will kneel down to the Qilin Group."

...

“Thanks to gallium nitride chip technology, we are able to increase the charging voltage to 225w.

Of course this is not the limit.

Our laboratory is already conducting experiments with 300-watt charging technology.

I believe it won’t be long before we can fully charge a mobile phone battery in 5 minutes.

At that time, everyone can enjoy the experience of ten hours of talk time after charging for five minutes.

Now that the introduction is here, let’s take a look at the products of our friends.”

Wei Zhaosheng said and pointed the thermometer at the other three mobile phones.

Kirin's cobalt-free batteries are all good, with the temperature maintained at around 45 degrees, while others can only be described as miserable.

The average battery temperature of the other three companies is above 55 degrees.

The most awesome ones reach 60 degrees.

We still need to take it apart to find out which brand it is.

However, Wei Zhaosheng did not reveal it on the spot if he hit someone or not in the face.

“I believe everyone can already see the difference between these products.

Even the most common Kirin battery has much better performance than those from other manufacturers.

Of course, this alone cannot prove the safety of Kirin batteries." Wei Zhaosheng said as he opened the announcement of the second trolley.

On the red cloth is an instrument with a needle.

"This machine is called an acupuncture tester. I believe all battery-making friends know that this instrument is mainly used for acupuncture experiments.

The acupuncture test is the simplest battery safety testing method.

If a general battery is punctured by a needle, it will cause the battery to catch fire or explode.

No matter you are an adult or a child, please do not imitate, because this is a very dangerous experiment.

Next, we will conduct experiments on ordinary Kirin batteries first," Wei Zhaosheng said.

The staff took out the Kirin mobile phone with ordinary battery from the charging test trolley and showed it to the audience.

He then disassembled the phone on the spot.

This staff member is a member of the maintenance department and dismantles the machine very quickly.

It only took eight minutes to take it apart.

"Damn it, this guy's hand speed must have been single for at least thirty years."

"You can't do it even if I give you thirty years of single life. This guy should be from the Kirin maintenance department. He can only do it if he often disassembles his mobile phone."

"The quality of Kirin mobile phones is very good. They should not be broken that easily. If there weren't so many broken mobile phones, how could there be so many mobile phones for him to dismantle?"

"The quality of Kirin mobile phones is good, but you can't rule out man-made damage, such as being dropped and soaked in water. These situations are all normal."

"No matter how good a brand is, there will still be quality problems. It's just that Kirin sells more mobile phones, and its base is larger, so repairs will be higher."
