Investigation of graphite composite anode surfaces by atomic force microscopy and related techniques
The surface of a synthetic graphite (KS-44) and polyvinylidene difluoride binder (PVDF) anode for Lithium-ion secondary batteries is imaged using atomic force microscopy (AFM) and several related scanning probe microscope (SPM) instruments including: dynamic force microscopy (DFM), friction force microscopy (FFM), laterally-modulated friction force microscopy (LM-FFM), visco-elasticity atomic force microscopy (VE-AFM), and AFM/simultaneous current measurement mode (SCM). DFM is found to be an exceptional mode for topographic imaging while FFM results in the dearest contrast distinction between PVDF binder and KS-44 graphite regions.
