Ionic Conductivity alpha Silver Iodide

Alpha silver iodide is a form of silver iodided that forms above 420K. The animation shown uses a simplified version of the sturucture. The conductivity occurs by the Ag+ ions moving in and out of their interstial sites. For more detail on the 3D structure click here.

This can occur with all the Ag⁺ ions with the button labelled”Show conduction pathways” demonstrating how the silver ions throughout the sturcutre can move.

Alpha-AgI is known as a fast ion conductor. Fast ion conductors have many potential uses for example developments for solid electrolytes in batteries.
