Abstract

Rods-shaped Li6V10O28 powders were synthesized by rheological phase reaction. The ratio of the Li/V of the product sintered at 600 °C for 8 h was characterized by inductively coupled plasma. The structure, composite, and morphology of the product have been investigated by X-ray diffraction, scan electron microscope, transmission electron microscopy, and X-ray photoelectron spectrometry, respectively. After charge–discharge test using the product as the cathode material of lithium-ion batteries, the product calcined at 600 °C for 8 h exhibited an initial high discharge specific capacity of 212.4 mAh/g at a rate of 1.0 mA/cm2 in a potential range of 2.0 and 4.4 V, and its stabilized capacity still remained 167.7 mAh/g after 30 cycles, which indicates that the rods-shaped Li6V10O28 are promising cathode materials in lithium-ion batteries.
