Efficiency of carbon layer growth in Li4Ti5O12/C composites studied by XPS and Raman spectroscopy

Abstract

The understanding of carbon layer formation is very important for core-shell composite electrodes, comprised of a low conductive core (active material) with a thin carbon shell (conductive additive). In this work we analyze the carbon morphology evolution for the two series of Li4Ti5O12/C samples with carbon content increasing from 0.9 to 5.6 wt%
