A dissolving kettle of lithium salt additive consists of a kettle body, an electric motor, a stirring shaft, a stirring leaf, a feeding mouth and a feed outlet. The kettle body is used to accommodate the material and the electrolyte after the mixing. The motor is set above the top of the kettle body, and the mixing shaft is vertically arranged on the inner central axis of the body of the kettle and passes through and passes through the inner axis of the body of the kettle and passes through and passes through through the inner axis of the tank body and passes through and through through through the inside of the cauldron body and through through the shaft and through through the inner axis of the tank body and through through. The top of the kettle body is connected with the motor. The mixing leaf is fixed on the stirring shaft inside the kettle body and synchronously rotates with the stirring shaft. The feeding mouth is arranged on the top of the tank body, and the outlet is arranged on the side wall of the kettle body and keeps a certain distance from the bottom of the kettle body. After the mixing, most of the undissolved solid lithium salt additives sink to the bottom of the dissolving kettle, and a few solid lithium salt additives that remain in the medium and upper solution can also be blocked in the tank by the filter device of the outlet, so that the obtained solution has high clarification and little impurity.
