Electrochemical study of doped LiFePO4 as a cathode material for lithium-ion battery

Abstract

LiFe1-xVxPO4/C (x= 0.01, 0.03, 0.05, 0.1) composites had been obtained by sol-gel method and characterized with the use of the XRD-analysis, SEM and charge/discharge tests. The doping was shown to result in decrease of electrode polarization, and correspondingly in capacity increase at high C-rates.
