Structural and electrochemical properties of LiV3O8 prepared by combustion synthesis

LiV3O8 powders were prepared by combustion synthesis, using metallic nitrates as the oxidant and metal sources and urea as fuel. The effect of (Li + V)/CO(NH2)2 ratio and heat-treatment temperature on the structure and electrochemical properties were discussed. The electrochemical behavior of the product showed that sample B1 synthesized at 300 °C with 1:0.5 ratio of (Li + V)/CO(NH2)2 showed the highest initial discharge capacity of 317.3 mAh g−1 and the best cycle ability with 238.9 mAh g−1 after 30 cycles.
