YUGE, IF TRUE: Fisker has filed patents for solid-state batteries.

Though Fisker is a very small car company that is currently taking deposits for its upcoming EMotion electric sedan, there are reasons to believe that the company could fulfill this promise. One of the members of the battery-development team was a co-founder of Sakti3, a company that formed to develop new batteries and announced its research into solid-state technology back in 2011. That company was purchased by Dyson, the vacuum cleaner company, which also intends on producing electric cars that AutoExpress reports will feature solid-state batteries in 2020. Toyota is also expected to have solid-state batteries just ahead of Fisker around 2022.

The reason all these companies are working on developing solid-state batteries is because they present a whole host of advantages over what you’ll find in today’s phones, computers and cars. The two big ones are greater energy density and rapid charging times. Fisker claims the batteries it’s developing have an energy density 2.5 times that of current batteries, and they should be capable of providing a 500-mile driving range. The company also says the batteries could be recharged in as little as a minute.

If they can be produced affordably at scale…
