A new nanowire-based lithium hexaoxotungstate anode for lithium-ion batteries.

ABSTRACT

This study reports one dimensional lithium hexaoxotungstate (Li6WO6), with a diameter in the range of 200-500 nm, as a novel anode material for lithium-ion batteries. The electrochemical performance of lithium hexaoxotungstate was investigated and a discharge capacity of 705 mA h g-1 was achieved after 50 cycles, along with an excellent rate capability. The 1D morphology of the material is believed to provide excellent transport properties, resulting in a high rate capability. The remarkable electrochemical performance of the Li6WO6 nanowires indicates that this new class of anode holds a lot of promise for future deployment in energy storage devices.
