"CP-3D-AFM, enables spatial charge distribution of both local electrode surface and electric double layers. The team used CP-3D-AFM to determine the charge rearrangements of ionic liquid/HOPG and WiS/HOPG interfaces and observed sub-nanometer variations in charge density, which is crucial for capacitive energy storage and other electrochemical functions of these systems... applicable to practical electrochemical devices including batteries, fuel cells, electrolyzers, and supercapacitors"
