NASA: Developed a new aerospace-grade battery that can easily extend Tesla’s range to 1,200KM

Despite the rapid development of new energy vehicles, there is one key issue that has not been upgraded too much, which is battery density.

How do major car companies now solve car range anxiety? The current approach is either to directly produce hybrids, or to use ultra-high voltage fast charging technology for new cars. To put it bluntly, it means high current and high voltage, so that new cars can be charged faster. There is also battery swapping technology, which is currently used by NIO and SAIC. The advantages are obvious, but the disadvantage is that the cost investment is too high and the return period is too long. Of course, there is another method that is commonly used by major car companies, which is to increase the size of the battery to obtain longer battery life. In essence, these technologies are not big breakthroughs.

It can be said that if batteries do not continue to make breakthroughs in the future, the development of new energy vehicles will be severely restricted. How to make batteries of the same size have longer battery life is what many battery manufacturers and new energy vehicle manufacturers are constantly pursuing.

According to an announcement issued by NASA, they have developed a new aviation-grade solid-state lithium-ion battery. The advantages of this battery are obvious: the density of the new battery will be unprecedented, reaching 500Wh/kg, which is the density of all known automobiles. The densest among batteries.

With a battery of the same size, if Tesla's 4680 battery is replaced, the battery life of Tesla Model 3 or Model Y can be easily increased to 1,200km, which is very amazing.

As an aerospace-grade battery, safety factor is also essential. According to an announcement issued by the agency, the battery not only has a greatly increased density, but also can continue to work at high temperatures. Its safety factor is twice that of existing car batteries, so it can greatly reduce the risk of spontaneous combustion in cars.

The battery structure shows that the battery will use oblate-shaped positive and negative electrodes, which are then connected in series and parallel, and a separator is used in the middle. The advantage of this is that the battery can be greatly integrated, which reduces the outer packaging of a single battery and naturally reduces the weight of the entire battery. Since the outer packaging is eliminated, more battery materials can be accommodated, and the battery life is naturally better.

In fact, not only the United States, but also China's aerospace technology has begun to be gradually converted to civilian use. For example, the Mach power technology on aircraft has been absorbed and used by Dongfeng Group, which developed the Mach power system and achieved higher performance. Chery also applied for a car seat ejection device. Generally speaking, this design was originally used on fighter jets.

Nowadays, more and more high-tech aerospace technologies are being used in new energy vehicles. In fact, this also means that new energy vehicles are indeed becoming more and more intelligent.
