A unique hollow Li3VO4/carbon nanotube composite anode for high rate long-life lithium-ion batteries

A unique hollow Li₃VO₄/CNT composite is synthesized via a facile method as an anode material in lithium batteries. Our work opens up the way for a promising material with high rate capability and good cycling stability due to its efficient Li⁺ diffusion and relatively high structure stability.A unique hollow Li₃VO₄/CNT composite is synthesized via a facile method as an anode material in lithium batteries.
