Summary: Further to the title of this paper, the “solid” I’m referring to is solid-state batteries. An EV battery has three electro-active components: anode, cathode and electrolyte. All batteries used in EVs (mostly lithium-ion batteries) use a liquid or perhaps gel electrolyte. These are definitely not solid-state. Solid-state batteries have been considered the wave of the future for several years now. Perhaps the future is closer than we think.
