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

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%

Raman spectroscopy as a structural characterization tool for lithium iron phosphates

Lithium iron phosphate LiFePO4 (LFP) with olivine structure was proposed to be used as a positive electrode material for lithium batteries in 1997 [1]. Twenty one years later LFP-based cells are widely used in traction batteries (LFP is the dominating cathode material for electric buses batteries) and stationary energy storages systems for grid balancing and renewables. Maybe, partially due to such a fast transition from promising to industrial-scale-produced positive electrode material, LFP still needs in some basic researches. One of the most important in the times of fast production scaling-up and steady price per kW∙h decreasing is the structural characterization...
