Abstract

Lithium vanadium phosphate, Li₃V₂(PO ₄)₃ was prepared by a simple solid state route. It was found that making a fine powder of Li₃V₂(PO ₄)₃ by the mechanical milling is very effective for increasing the insertion/extraction of lithium from Li₃V ₂(PO₄)₃ structure. In charge/discharge test, the ball-milled Li₃V₂(PO₄)₃ sample exhibited a higher initial discharge capacity of 174 mAh/g in the voltage range of 3.0-4.8 V, compared with pure Li₃V₂(PO ₄)₃ sample (152 mAh/g). Furthermore, the ball-milled Li₃V₂(PO₄)₃ presented not only higher cycle retention rate after 50 cycles, but also better rate capability compared with pure sample in the whole region (0.1-7 C).
