Lithium-ion battery technology has made impressive gains over the years. Today’s cells are cheaper than they’ve ever been, but lithium-ion still leaves a lot to be desired in terms of energy density compared to liquid hydrocarbon fuels. Which means that putting enough of them in a car to give it an acceptable range adds a lot of mass and volume. Which is where solid-state batteries come in.
In a traditional battery, a pair of electrodes are immersed in an electrolyte solution, and it’s this liquid electrolyte that allows ions to
