The bet that StoreDot is making is that it's not the absolute charge range of an electric vehicle that matters; it's how quickly you can extend that range. So, while it's leveraging research on technologies that allow greater capacity in lithium-ion batteries, it's turning around and sacrificing some of that capacity in order to make charging faster.

Put differently, the bet is that people would rather add 300km to the range of their car in five minutes than have a car with a 600km range that takes an hour to fully charge.
