The latest website: The second is the car. The battery life of electric vehicles has always been a commonplace issue, and it is also the issue that many consumers are most concerned about. If this new super solid-state battery is used, its cruising range will be able to be increased by three times.

Take Tesla, the electric car brand that is the most popular among electric vehicles and is also the most popular among consumers, as an example. Its electric car has a cruising range of about 400 kilometers, which is already a relatively good existence in the field of electric vehicles. If this new type of super solid-state battery is used, its cruising range will reach an astonishing 1,200 kilometers, which is far beyond the mileage that ordinary family cars can run after filling up a tank of gas.

When Wu Hao told this example to the people present, there was another exclamation. Not only were more and more people crowded around, even media reporters rushed over after hearing the news.

Seeing such a restless person, Wu Hao couldn't help but smiled wryly. This professional exhibition that was agreed upon, why did so many people flock here all of a sudden?

Immediately, he gestured to the staff next to him. The staff understood and then went to the security department of the exhibition to maintain order and evacuate the crowd.

Willy, who had been listening to Wu Hao's explanation, couldn't help drooling at the battery, his eyes seemed to be looking at a beauty, or a huge diamond, instead of looking at the battery. There is no doubt that the color of greed is exposed.

"Xiao Wu, how about its service life, is it durable?" Li Weiguo ignored the crowd around him, but focused entirely on the battery.

Wu Hao nodded and said: "It's relatively durable. Let's take the ordinary lithium-ion battery that everyone is using as an example. The charging and discharging life of our battery will be 100% higher than that of ordinary lithium-ion batteries. Twenty to thirty percent or so.

And this battery is also more resistant to low temperature, high temperature, corrosion, puncture and vibration than ordinary lithium-ion batteries.

Ordinary lithium-ion batteries will become inactive at low temperatures and their performance will drop significantly. But this battery is not so obvious. We tested it in the laboratory. In the extremely low temperature environment of minus 60 degrees, this battery only lost about 20% of its power.

It still performs well in high-temperature environments. The normal operating temperature we marked for this battery is below 85 degrees and above minus 60 degrees. This temperature is also sufficient to cope with the highest and lowest temperatures in the current natural environment.

Ordinary lithium-ion batteries are very afraid of punctures because they use a diaphragm folding process. Once the diaphragm is ruptured, a short circuit will occur, and there will be dangers such as burning or even blasting.

First of all, this battery is solid state,

The material is relatively hard and has good anti-puncture and anti-scratch properties. And the 3D three-dimensional sponge structure we developed, even if the needle penetrates it, it only penetrates a very limited internal area. There will be no short circuit and violent reaction, nor will it affect the normal work of other areas.

Then there is a relatively stable internal structure, which can withstand strong shock and vibration, and can also resist certain corrosion. "

Changing to a demo picture, Wu Hao continued to say with an emphasis: "What is even more amazing about this battery is that it supports fast redischarging, which is several times faster than traditional batteries.

Also taking a 1000mA battery as an example, an ordinary lithium-ion battery can be fully charged in about ten minutes at the fastest using fast charging technology. At present, the fast charging technology on the market is also developing rapidly. It is said that the latest technology can reach five minutes.

And our battery is also fully charged with 1000mA, and it only takes ten seconds to fully charge it. "

coax!

The scene was boiling again, the sound of the flash and the shutter came one after another, and Wu Hao and the others couldn't open their eyes when they were flashing.

"This is really a pioneering work, a great pioneering work." Li Weiguo grabbed Wu Hao's hand and said excitedly: "Xiao Wu, you must have a place in this year's Major Science and Technology Progress Award, no one can say So, I'm sure."

Wu Hao did have this opportunity before, but for various reasons. In fact, there are only two, on the one hand for the sake of confidentiality. On the other hand, considering that he was too young, they all missed him. This made Wu Hao a little disappointed, and also made Li Weiguo and other people who knew about his related technology indignant.

It's been such a long time, I didn't expect Li Weiguo to still be worried about it, remembering it.

"Xiao Wu, Xiao Wu, what about the cost, how about the manufacturing cost, and whether it can be put into commercial use." Song Chunming said eagerly.

Upon hearing this question, the scene immediately became quiet again. Everyone looked at Wu Hao, eager to know the answer. In fact, many well-known battery research and scientific research institutions have claimed that they have developed new high-performance battery technology, but it is not clear whether it is true or not, and it is not clear whether it can be commercialized. Anyway, there is no result in the end.

There are many reasons for this failure, among which the biggest factor is the manufacturing cost and whether it can be commercially used on a large scale. The cost is too high, the manufacturing technology is too complex, not safe enough, not environmentally friendly, etc., all of which will prevent the battery from being put into commercial production.

So everyone is also very concerned about this issue. Only when it can be put into commercial use can this new super solid-state battery technology have commercial value.

Wu Hao nodded at everyone with a smile and said: "Compared with ordinary lithium-ion batteries, the cost of this new super solid-state battery is still relatively high. But if it can be mass-produced, then the cost can be reduced.

But what is certain is that this battery can be put into commercial production. "

After listening to his words, everyone also showed joyful smiles, but Wu Hao immediately changed the topic: "Of course, this battery technology is not perfect, and there are still some problems that have not been solved. Secondly, we also have to pay attention to its reliability. And security testing for a long time to make sure it is reliable enough and safe enough."

"Indeed, there are still many problems to be solved in order to put a new type of battery into commercial use." Li Weiguo also nodded and said, but the smile on his face did not dissipate.

He looked at the people around him, and then seriously told Wu Hao: "Xiao Wu, this battery technology is very advanced, and it will greatly promote our national defense construction, technological development, and even social progress. So Ah, you must keep it well, and you must not let this technology leak out in vain.

In this way, I immediately notified the relevant departments, and we seized the time to hold relevant technical demonstration meetings as soon as possible. Once the technical demonstration is passed, then the actual production can be carried out.

I believe that with the blessing of this battery, many of our advanced weapons and scientific research equipment can be blessed, thus raising the combat power and performance to a new stage. "
