The present invention relates to nanostructured materials. The material consisting of small lumps of needles enclosed in a non-continuous layer of spherical carbon particles ssajin Li 1 + α V 3 O 8 and the β-Li x V 2 O 5 (0.1≤α≤0.25 and 0.03≤x≤0.667) Nanostructured carbonaceous material. The material is a carbon, α-V 2 O 5 and Li precursor concentration ratio of [V 2 O 5 ] / [Li] is 1.15 to 1.5 and (carbon) / (carbon + V 2 O 5 + Li precursor) of A carbonaceous precursor gel was prepared by contacting the weight ratio to 10 to 15%, and the obtained gel was subjected to the first heat treatment step for 3-12 hours at 80 ° C-150 ° C and 300 ° C to 300 ° C under nitrogen or argon atmosphere. It is prepared by carrying out a heat treatment consisting of a second heat treatment step at 350 ° C. for 10 minutes to 1 hour. Use: Anode active material.n n n n Battery, Positive electrode, Negative electrode, Electrolyte, Li precursor, α-V2O5 |
