Yeah, so you have to divide it by a factor of 5. Which still makes gasoline roughly 5 times as energy dense than this prototype battery, instead of 25 times.
Another problem is the increased complexity of fossil fuel vehicles, specifically in stuff like the engine, gears, pollution filters, etc. A fossil fuel vehicle is just intrinsically more complicated. Which doesn't directly relate to the density, but it gives electric vehicles an advantage.
Also no regenerative braking
Which is where hybrids have a huge advantage, getting the best of both worlds
