Episode 31: Ionic Conduction
Meet the materials that allow ions to move right through them!
Diffusion is when atoms move through a material in response to a concentration gradient. However, some ions can move through a material in response to an electric field and can do so very quickly! Even more remarkable, the motion of ions can be restricted to ions of a certain type such as O2-, H+, Na+, Li+ etc. What is required of a material in order for it to be an ionic conductor? What technologies do ionic conductors make possible? Why are they necessary for batteries, fuel cells, sensors, electrolyzer, and more? We answer these questions and dive into the exciting recent news of solid-state batteries in this episode. We cover some of the key fast ion conductors like YSZ, BASE, LSGM, Nafion, LLZO, and NaSiCON.
