Hierarchical flower-like Ni3V2O8/Co3V2O8 composites were prepared by a simple one-step hydrothermal process. When employed as an anode for lithium-ion batteries (LIBs), the fabricated Ni3V2O8/Co3V2O8 composites exhibited significantly improved lithium storage performances with superior discharge capacity (1142.7[Formula: see text]mAh[Formula: see text]g[Formula: see text] at 100[Formula: see text]mA[Formula: see text]g[Formula: see text]), excellent cycling stability (933.2[Formula: see text]mAh[Formula: see text]g[Formula: see text] after 600 cycles at current density of 500[Formula: see text]mA[Formula: see text]g[Formula: see text]) and remarkable rate capability (607.6[Formula: see text]mAh[Formula: see text]g[Formula: see text] even at rate of 5000[Formula: see text]mA g[Formula: see text]). The superior electrochemical properties could be attributed to the hierarchical flower-like structure and impressive synergistic interplay between Ni3V2O8 and Co3V2O8, which resulted in improved electronic conductivity and stable mass transfer. This interesting hybridization strategy might open a new avenue to prepare micro/nanostructured composites for high-performance energy storage devices.

Enhanced Electrochemical Performance

Novelty Cu2O multi-branched nanowires and nanoparticles with size ranging from [Formula: see text]15[Formula: see text]nm to [Formula: see text]60[Formula: see text]nm have been synthesized by one-step hydrothermal process. These Cu2O nanostructures when used as anode materials for lithium-ion batteries exhibit the excellent electrochemical cycling stability and reduced polarization during the repeated charge/discharge process. The specific capacity of the Cu2O nanoparticles, multi-branched nanowires and microscale are maintained at 201.2[Formula: see text]mAh/g, 259.6[Formula: see text]mAh/g and 127.4[Formula: see text]mAh/g, respectively, under the current density of 0.1[Formula: see text]A/g after 50 cycles. The enhanced electrochemical performance of the Cu2O nanostructures compared with microscale counterpart can be attributed to the larger contact area between active Cu2O nanostructures/electrolyte interface, shorter diffusion length of Li[Formula: see text] within nanostructures and the improved stress release upon lithiation/delithiation.
