Abstract
- Constructing Two-dimensional (2D) nanostructures into 3D architecture towards specific applications is desirable but challenging. In this work, we construct 2D Cu 3 V 2 O 7 (OH) 2 ·2H 2 O nanoplates into 3D nanoflowers via Cu 2 O sacrificial template method. The employed Cu 2 O nanocubes not only serve as template but also supply the Cu resource during the synthesis strategy. The morphology and structure of Cu 3 V 2 O 7 (OH) 2 ·2H 2 O are characterized by XRD, SEM, and TEM techniques. The Cu 3 V 2 O 7 (OH) 2 ·2H 2 O nanoflowers show combined structural benefits for electrochemical performance, such as high surface area and short migration path for lithium storage, as well as tunnels for electrolyte filtration. Therefore, high capacity, stable cyclability, and especially high initial coulombic efficiency of 91.3% are obtained from Cu 3 V 2 O 7 (OH) 2 ·2H 2 O nanoflowers, making it a promising anode material for lithium-ion batteries.
