[16p-2U-11] Local electrochemical analysis at the LiCoO2 thin films by nanoSECCM
Keywords:scanning probe microscopy,lithium-ion battery,electrochemistry
In this research, we have used scanning electrochemical cell microscopy for investigating the current response at the surface of LiCoO2 thin films. By the localized electrochemical measurement (cyclic voltammogram), the peak was observed at about 0.9 V(vs Ag/AgCl) , corresponding to ionic current related to lithium-ion desertion at about 3.9 V(vs Li/Li+). Further, we continue this study using by epitaxial thin films with controlled crystal orientation and grain boundaries.
