A bit of confusion on Toyota SS batteries on here. They do use Lithium just a solid Pure form, so Lithium mines are still required!
The structure of a solid-state battery
However, the internal structure of a solid-state cell is very different, as all its parts are solid. While in traditional lithium batteries, the electrolyte is a liquid, solid-state cells are formed of:
A cathode (or positive electrode), which can be made with the same compounds as a lithium-ion battery (eg. LFP, NMC, LMO, etc)
A separator, generally ceramic or solid polymer, which also works as the electrolyte
An anode made of lithium metal (pure lithium)
