Commercial graphites for Li-ion battery applications

In this work we have examined different types of synthetic graphites (SFG and KS types) that have different morphology and particle sizes. In our analysis we examined the incremental capacity (dC/dV), which shows a series of peaks that correspond to potential plateaus. This approach enable us to identify the processes involved (formation of SEI, Li+ intercalation or de-intercalation, etc.). Our analysis was mainly concentrated on the first lithiation, in an attempt to specify the origin of the capacity loss related to each type of synthetic graphite.
