V[sub 2]O[sub 5]-Coated TiO[sub 2] Nanorod Electrodes

-coated nanorods with a shell thickness of 6.5 nm were prepared by coating on anatase nanowires. These coated nanorods demonstrated a superior rate capability and capacity at higher C rates with respect to the nanowires. The volumetric capacity of the core-shell nanorods were 426 and at 0.5 and 20C rates, respectively, while those of the nanowires were 246 and , respectively. The enhanced electrochemical properties were due to both a fully reversible phase transition of the nanoscale- shell to the crystalline phase, in contrast to bulk to the amorphous phase and its faster pathways for Li ions and electrons into the core.
