Graphites for Li-ion cells: Study of the irreversible capacity using differential capacity analysis

Graphites for Li-ion cells: Study of the irreversible capacity using differential capacity analysis The aim of this work is to examine the performance and in particular the irreversible capacity of synthetic graphites. Our analysis is based on the evaluation and study of the differential capacity (dx/dV), computed by numerical differentiation of the galvanostatic curve. The dx/dV curve shows a series of peaks that correspond to potential plateaus. The area under each peak results in the charge related to the particular process, and by peak de-convolution analysis we can determine the charge consumed by or released from each process. This approach enables us to identify the processes involved (formation of SEI, solvated Li co-intercalation, cell self discharge, etc.). http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Ionics Springer Journals

Abstract

The aim of this work is to examine the performance and in particular the irreversible capacity of synthetic graphites. Our analysis is based on the evaluation and study of the differential capacity (dx/dV), computed by numerical differentiation of the galvanostatic curve. The dx/dV curve shows a series of peaks that correspond to potential plateaus. The area under each peak results in the charge related to the particular process, and by peak de-convolution analysis we can determine the charge consumed by or released from each process. This approach enables us to identify the processes involved (formation of SEI, solvated Li co-intercalation, cell self discharge, etc.).
