Abstract

To evaluate the possibility of using nanosized TiO2to replace the carbonaceous materials usuallyemployed as the negative electrode of lithium-ion batteries, we studied and compared the electrochem-ical performance of TiO2nanotubes with a commercial material (P25 Degussa). TiO2nanotubes wereprepared by electrochemical anodization of titanium sheets. The nanotubes were characterized by usingSEM and XRD. Composite electrode tapes were made by roll milling the TiO2nanotubes and the TiO2P25 Degussa with carbon and Teflon. The electrodes were electrochemical characterized in lithium cellby charge/discharge cycles. The electrochemical tests comprised low rate cycling, cycling at C/rate andcycling at different rates. © Elsevier Ltd.
