why the new electric Volkswagen car will be able to charge within 15 minutes but phones can still take hours to fully charge
In: Technology
Many years ago I listened to a podcast (Scientific American maybe) where they interviewed an MIT scientist who worked on battery research. He claimed there is something about the molecular structure of a normal lithium ion battery that limits how fast a battery can be charged. In his research he had found a way to change the battery’s molecular structure. He claimed to have produced a phone battery that could fully charge in 10 seconds. According to his estimates, with a powerful enough electric source (higher voltage than household current) you could fully charge a car battery made this way in about the same time it takes to fill a gas tank. Supposedly the technology was patented and the only thing left was to work out the technical issues with mass production. After listening to that podcast I thought that fast charging batteries would have been the norm long ago.
