The utility model discloses a multi-anode lithium metal electrolytic bath which comprises an outer bath body, a lining body, cathodes, anodes, and a tank cover which covers the tops of the outer bath body and the lining body to form an accommodating cavity used for accommodating electrolyte, wherein a chlorine outlet through which chlorine is discharged and a lithium outlet through which lithium metal is discharged are formed in the tank cover; the cathodes are arranged into a circle around the outer sides of the anodes; the anodes are uniformly distributed in the lining body; the cathodes are connected with cathode busbars; the anodes are connected with anode busbars; the cathodes are fixed inside the lining body; the number of the anodes and the number of the cathodes are the same and both at least four; the diameter of each anode is 200-300mm; the upper end of each anode is fixedly arranged on the tank cover in an insulating manner; and the lower part of each anode is fixedly arranged on the lining body by virtue of an anode base in an insulating manner. The multi-anode lithium metal electrolytic bath disclosed by the utility model is simple in structure, the probability that the anode graphite is broken can be reduced, the service life of the anode graphite is prolonged, and the operating cost of lithium metal electrolysis is reduced.
