alpha-MoO3-In2O3 core-shell nanorods were prepared by a facile two-step hydrothermal method. As the anode of lithium-ion batteries, their reversible capacity was up to 1304 mA h g(-1) at 0.2 C rate ( 5 hours per half cycle) and maintains 1114 mA h g(-1) after 50 cycles. At a rate of 0.3 C, 0.5 C, 1 C and 2 C, the discharge capacities after 50 cycles were maintained at 938, 791, 599 and 443 mA h g(-1), respectively. The enhanced electrochemical performance can be ascribed to the synergistic effect between alpha-MoO3 and In2O3, one-dimensional core-shell nanostructures, short paths for lithium diffusion and interface spaces.
