A liquid or gel substance that allows ions to move between the electrodes while blocking the direct flow of electrons.
A thin, porous membrane that keeps the anode and cathode from touching (which would cause a short circuit) while allowing ions to pass through.
The specific minerals inside a battery define its performance, weight, and cost. Lithium-ion batteries, which power most modern gadgets and electric vehicles (EVs), contain several key materials: Battery Passport Content Guidance
