Fabrication and characterization of composite electrodes for lithium-ion batteries

This paper reports the preparation and the characterization of composite electrodes based on TiO₂ and LiFePO₄. The electrodes were studied by using XRD, SEM, and charge/discharge cycles. The electrochemical tests comprised low rate cycling and cycling at different rates. The electrodes were used for the fabrication of lithium-ion batteries. Battery cells were assembled and electrochemical tested at various discharge rates to evaluate cell capacity and capacity retention as a function of the discharge rate.
