Size Effects - Nanoionics

Size Effects - Nanoionics

Decreasing particle sizes to the nanometer scale modifies materials properties by several effects: (i) increasing density of interfaces, (ii) overlap of space charge zones, (iii) electronic confinement effects, (iv) ionic confinement effects, (v) internal pressure / surface energy. This can lead to completely new properties, e.g. allow for lithium storage in a composite where the individual phases are not electrochemically active.
