1. a kind of aluminum secondary battery, which is characterized in that the aluminum secondary battery includes anode, cathode, electrolyte and diaphragm, describedElectrolyte is AlCl3/[BMIM]Cl、

  • AlCl3/[EMIM]Cl、

    AlCl3/ [BMIM] Br and AlCl3It is any one in/[EMIM] BrKind, the anode is the combination for growing barium oxide and collector on a current collector, and the preparation method of the anode includesFollowing steps;

    (1) vfanadium compound is dissolved, obtains the vanadium ion solution that concentration is 0.05-0.15mol/L;

    (2) vanadium ion solution and collector are subjected in closed container hydro-thermal reaction, clean reaction product after reactionAnd vacuum drying, obtain growing the combination of barium oxide and collector on a current collector;

    (3) combination that step (2) obtains is calcined, the condition of the calcining includes;

    that temperature is 300-600 DEG C, the timeFor 1-6h;

    Wherein, in step (2), the mass ratio of the vanadium ion solution and the collector is 100;

    1-20;

    1, and the waterThe condition of thermal response includes;

    that heating temperature is 180 DEG C to less than 205 DEG C, and heating time is 1-4 days, and the barium oxide is in instituteStating the deposition on collector is 2-10mg/cm2
