There are two ways to solve the problem of electric vehicle range, one is to increase the range, and the other is to speed up the charging speed. Unfortunately, it is difficult for these two methods to be effectively studied.
It's just that South Koreans recently said that they have found new materials that can effectively increase the range of electric cars, which can increase the range of current electric cars to ten times the current one, and if this is the case, it will inevitably lead to a revolution in new energy vehicles.
For example, a year ago, South Korea said that it had invented a room-temperature superconductor, but it turned out to be a joke, so did they come out again this time?
The new battery, a joint invention between Pohang University of Science and Technology in South Korea and Sogang University in Seoul, is a polymeric material that can increase the battery's power storage capacity by a factor of ten.
At present, we mainly use lithium batteries, and graphite materials are mainly used for power storage. In fact, we have also found better silicon materials, but due to its expansion and contraction characteristics, it is technically difficult to solve, so the big guys mainly use lithium batteries.
But now the South Koreans say that they can form a device that wraps the silicon material by using hydrogen bonds, coulomb forces and other forces, so that it cannot expand and contract. If what they say is true, then the use of silicon batteries is bound to bring about a huge revolution in the industry.
At present, the cruising range of most car companies is about 600km, and a few who have gone too far will reach 1000km, but that is achieved by increasing the battery. If the new polymeric material can be perfectly combined with silicon, the car will have an incredible range of 4,000 km.
For example, the distance from my side to Urumqi is 3442km, if you drive a battery that can adapt to silicon materials, then you don't need to charge along the way to arrive directly, what kind of concept is this?
The new battery using silicon material can also have stronger safety and environmental performance, and the existing lithium battery must add harmful substances such as lead and nickel to ensure the operation of lithium ion, while silicon material does not need it at all.
Once this kind of battery is mass-produced, South Korea will inevitably become a pivotal presence in the new energy vehicle market, and it can be used not only in cars, but also in mobile phones or any device that uses electricity.
