Secondly, there are cars. The battery life of electric cars 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 tripled.
Take Tesla, the most popular electric car brand among electric cars and the most popular among consumers, as an example. The cruising range of its electric cars is about 400 kilometers, which is already relatively good in the field of electric vehicles. If this new super solid-state battery is used, its range will reach an astonishing 1,200 kilometers, which is far more than the mileage that an ordinary family car can run with a full tank of gas.
When Wu Hao told this example to the people present, he once again aroused exclamation. Not only were more and more people crowding around, but even the media reporters rushed over after hearing the news.
Seeing such a restless person, Wu Hao couldn't help but smile bitterly. Why did so many people flock to this professional exhibition that was promised?
Then he signaled to the staff next to him. The staff understood and started to go to the exhibition security to maintain order and evacuate the crowd.
Willie, who had been listening to Wu Hao's explanation, couldn't help but drooled when he looked at the battery. His eyes seemed not to be looking at the battery, but at a beauty, or a huge diamond, with an expression on his face. The greed is clearly revealed.
"Xiao Wu, how about its service life? Is it durable?" Li Weiguo ignored the crowd around him and focused entirely on the battery.
Wu Hao nodded and said: "It is still relatively durable. Let's take the ordinary lithium-ion battery currently used by everyone on the market as an example. The charge and discharge service life of our battery will be 100% higher than that of ordinary lithium-ion batteries. Around 20 to 30 percent.
Moreover, 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 and their performance will drop significantly in low temperature environments. But this battery will not be so obvious. We have tested it in the laboratory. In an 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 enough to cope with the highest and lowest temperatures in the current natural environment.
Ordinary lithium-ion batteries use a separator folding process, so they are very afraid of puncture. Once the separator ruptures, a short circuit will occur, causing dangers such as burning or even explosion.
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 a needle penetrates it, can only penetrate a very limited internal area. There will be no short circuit or violent reaction, nor will it affect the normal work of other areas.
Then there is the relatively stable internal structure, which can withstand strong impact and vibration, and can also resist certain corrosion. "
Changing to a demonstration picture, Wu Hao continued with an emphasis: "What's even more amazing about this battery is that it supports rapid re-discharge, which is several times faster than traditional batteries.
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. The current fast charging technology on the market is also developing rapidly. It is said that the latest technology can already reach five minutes.
As for our battery, it is also fully charged with 1000mA, and it only takes ten seconds to fully charge it. "
coax!
The scene was boiling with excitement again, with flashes and shutter sounds happening one after another, making Wu Hao and the others unable to open their eyes.
"This is really an initiative, a great initiative." Li Weiguo grabbed Wu Hao's hand and said with excitement: "Xiao Wu, you will definitely have a place in this year's major scientific and technological progress award. No one can say it. Yes, I guarantee it."
Wu Hao did have this opportunity before, but it was probably due to various reasons. In fact, there are only two. On the one hand, it is necessary to maintain confidentiality. On the other hand, considering that he was too young, they all missed him. This made Wu Hao slightly disappointed, and also made Li Weiguo and other people who knew his related skills angry.
It's been such a long time, but I didn't expect Li Weiguo to still be brooding about it and remember this incident.
"Xiao Wu, Xiao Wu, what's the cost? What's the manufacturing cost? Can it 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 institutions claim that they have developed new high-performance battery technology, but it is unclear whether it is true or false, and whether it can be commercialized. Anyway, there is no result in the end.
There are many reasons for this lack of follow-up, the biggest of which are manufacturing costs and whether it can be commercialized on a large scale. The cost is too high, the manufacturing technology is too complex, not safe enough, not environmentally friendly enough, etc., all of which can prevent batteries from being put into commercial production.
Therefore, everyone is also very concerned about this issue. This new super solid-state battery technology will have commercial value only if it can be truly put into commercial use.
Wu Hao smiled at everyone and nodded: "Compared to ordinary lithium-ion batteries, the cost of this new super solid-state battery is still relatively high. However, if it can be mass-produced, the cost can be reduced.
But what is certain is that this battery is completely ready for commercial production. "
After listening to his words, everyone also smiled with joy, but Wu Hao immediately changed the topic: "Of course, this battery technology is not perfect yet, and there are still some problems that have not been solved. Secondly, we must also ensure its reliability. and safety testing over a long period of time to ensure it is reliable enough and safe enough.”
"Indeed, if you want a new type of battery to be put into commercial use, there are still many problems that need to be solved." Li Weiguo also nodded, but the smile on his face did not disappear.
He looked at the people around him, and then said seriously to 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 preserve it well and never let this technology leak out in vain.
In this way, I immediately informed the relevant departments and we will seize the time to hold a relevant technical demonstration meeting as soon as possible. Once the technical demonstration is passed, actual production can begin.
I believe that with the blessing of this battery, many of our advanced weapons and equipment and scientific research equipment can be blessed, thereby raising combat power and performance to a whole new stage. "
