Correlated ion motions in electrolytes seen in real space

snapshot of electrolyte structure
A snapshot of electrolyte structure is shown, as determined by molecular dynamics simulation (left). The Van Hove function, determined by inelastic X-ray scattering of an aqueous NaBr solution is shown (right). Correlated motions of water, cation, and anion in pico-second timescale are disentangled through the partial Van Hove function.

Scientific Achievement: Correlated motions of water molecules and salt ions in real space and time were visualized through the Van Hove function.

Significance and Impact: Understanding the correlated motions of ions in liquid is a key to improving the mobility of ions in liquid electrolytes in many energy storage devices.
