To improve the performance of catalysts and batteries, it is very important to visualize the surface reactivity with the structure on a micro/nanoscale to understand the crystal orientation and grain boundary-dependent reactivity. Therefore, we have developed scanning electrochemical cell microscopy that uses a nanopipette as a probe to locally form an electrochemical cell and scan the nanopipette on the sample surface to visualize the reactivity of the sample surface. Using SECCM, we characterized the hydrogen evolution reaction of nanosheet material and the charge/discharge property of the lithium-ion secondary battery.
