Abstract

A structural model to calculate the electrochemical interface area for a composite graphite electrode is described. The chemical diffusion coefficient values (D_Li+) calculated for graphite electrodes of different thicknesses and porosities using this model are almost same as expected. The values of D_Li+ in the graphite vary between 10^-11.9 and 10^-9.9 cm²/s over the course of the lithium deintercalation in the graphite samples.
