Abstract
In Situ Electrochemical Atomic Force Microscope (AFM) was used to study Solid Electrolyte Interphase (SEI) film formation on the graphite anode surfaces in lithium ion battery. SEI film formation was clearly observed on the surface of KS-44 synthetic graphite composite electrode in 1M LiClO4 Ethyl-ene carbonate (EC) -based electrolyte under galvanostatic discharge. Together with quantitative analytical results of SEI films formed in several different electrolytes, we have concluded that direct electron transfer from the surface of graphite to solvated lithium ion caused the SEI film formation on graphite anodes in EC-based electrolytes.Keywords
