New Application Note Describes Atomic Force Microscopy for Characterizing Electrical Double Layer Properties in Ionic Liquid Electrolytes
14 June 2017

As energy storage devices shrink, new characterization methods are necessary to allow in situ studies of nanoscale dynamics inside electrochemical cells. Learn how Atomic Force Microscopy (AFM) is being used to tackle this challenge with this informative new application note released by Oxford Instruments Asylum Research — “Toward Better Charge Storage: AFM Determines Key Electrical Double Layer (EDL) Properties in Future Ionic Liquid Electrolytes”. The application note discusses how AFM can be used for high resolution imaging of the ionic liquid EDL, as well as measuring the ion layering in electrochemical capacitors with force curves.
