1. carbon carries a lithium vanadate, it is characterized in that:

  • described carbon carries lithium vanadate and adopts following steps synthesis to obtain,1) at room temperature ~ 90 DEG C, by lithium-containing compound and vanadium-containing compound with the mol ratio of lithium ion and vanadium ion for 1;

    (2.9 ~ 3.1) ratio in water, react 0.5 ~ 10h, described water and the weight ratio of solid mixture are 1;

    (0.01 ~

         1);

    2) in step

         1) in add carbon dust in obtained aqueous systems;

    The control addition of carbon dust and the mass ratio of target product lithium vanadate are 1;

    (1 ~

         20), continue to heat 0.5 ~ 1h at 90 ~ 100 DEG C;

    3) by step

         2) in mixture in moisture all volatilize at 90 ~ 100 DEG C, obtain carbon and carry vanadium lithium composite material;

    4) by step

         3) in carbon carry under vanadium lithium composite material is placed in inert gas atmosphere, heat-treat at 250 ~ 450 DEG C, the processing time is 0.5 ~ 30h, is then cooled to room temperature, obtains solid product carbon and carries lithium vanadate.
