Abstract

original image

Scanning ion conductance microscopyimaging of battery electrodes, using the geometry shown in the figure, is a tool for in situ nanoscale mapping of surface topography and local ion current. Images of silicon and tin electrodes show that the combination of topography and ion current provides insight into the local electrochemical phenomena that govern the operation of lithium ion batteries
