I'm not understanding, perhaps you can enlighten me. The article says "The battery has an energy density of 24 Wh/kg, meaning approximately 20 percent capacity compared to comparable lithium-ion batteries currently available." But the article goes on to say, "since the weight of the vehicles can be greatly reduced." If you need 5x the weight of this kind of battery than if you used Li Ion battery, and a Li Ion battery constitutes 1/3 the mass of a car (at a guess), how is there any savings? Seems like the result will be even heavier than current EVs.
