One-step construction of hexagonal WO3 nano-shuttles with enhanced lithium storage performance

WO 3 nano-shuttles were prepared and used as anode of Li-ion battery. A reversible capacity of 614.7 mA h g −1 was achieved after 300 cycles at 0.5 A g −1 . The intrinsic tunnels and mesoporous characteristics are conducive to lithium ion intercalation.
