Abstract
- Co 3 V 2 O 8 hexagonal pyramid was successfully fabricated via a simple hydrothermal process and subsequent heat treatment. The inner structure of the hexagonal pyramid was further adjusted by controlling the size of Co 7 V 4 O 16 (OH) 2 (H 2 O) precursors. Hierarchical Co 3 V 2 O 8 hexagonal pyramid with height of 1 μm were orderly constructed from 60–80 nm inter-connected particles, showing numerous interval voids. Benefiting from its unique structure, the as-prepared sample showed higher electrochemical performance as an anode material for lithium-ion batteries than that of another bulk sample with height of 5 μm and adhesive inner structure. When tested at a current density of 500 mA g −1 , the hierarchical Co 3 V 2 O 8 hexagonal pyramid exhibited good rate capacity, high cycling stability, and excellent discharge capacity up to 712 mA h g −1 , making it promising electrode materials for lithium-ion batteries.
