One-step construction of hexagonal WO nano-shuttles with enhanced lithium storage performance.

In this work, WO nanorod-based aggregates and WO nano-shuttles were constructed by a facile hydrothermal route. The structure, morphology, element composition and valence state of the formed WO samples were characterized using different testing instruments. As the active anode for lithium-ion batteries, the WO nano-shuttle electrode can deliver a reversible specific capacity of 614.
