The promised land of electric vehicles is inherently tied to our ability to mass produce vehicular-grade solid-state batteries. I know, I know, there are keyboard warriors right now queuing up in our comments to say, "bUt wE AlReAdy hAvE eVs tHaT WoRk fOr eVeRdAy LiFe!"
Well, for quite a few people, they don't. So much so, despite the online rhetoric of the EV revolution, and my own belief that they're likely the future, only 1.9% of the cars on the road right now are EVs. That's still quite a few vehicles, something north of what's likely 5 million cars, trucks, and SUVs. But these machines still struggle both in terms of range and charging, as well as public charging infrastructure. Two, however, could theoretically be solved with solid-state batteries, which due to their energy density, efficiency, and ability to be rapidly recharged, would moot both range and charging speeds.
