ITO/MWCNT Nanocomposites as New Novel Anode Electrodes for Li-Ion Batteries

Abstract

In this study, we present a new anode electrode consisting of Indium Tin Oxide and multiwall carbon nanotube based buckypapers for high efficient lithium ion batteries. Core/shell Indium Tin Oxide/Buckypapers were produced by vacuum filtration techniques followed by an rf magnetron sputtering. The nanosized indium tin oxide particles were uniformly anchored onto the surfaces of buckwapers with a mean grain sizes of 2-7 nm confirmed by the FESEM, TEM and XRD results. The as-prepared nanocomposite anode electrodes exhibited outstanding reversible capacity (859, 875 and 895 mA h g(-1) after 50 cycles) and no significant capacity fading is observed after 50 cycles. The unique nanocomposite architecture which integrates both elebtronic conductivity and buffering matrix design strategies, contributing to enhanced lithium storage performance.
