Titanium diboride powder preparation device for lithium battery preparation

The titanium diboride powder preparation device comprises a preparation container, a controller, a gas pressure meter and a servo motor, the output end of the servo motor penetrates through the preparation container and is fixedly connected with a ball screw nut pair, a kettle wall contact assembly is arranged outside the ball screw nut pair, and the kettle wall contact assembly is connected with the controller. According to the titanium diboride powder preparation device, when a lead screw rotates in the axial direction, a dispersion assembly rotates to drive materials at the bottom of a kettle body to be dispersed and stirred, and the preparation speed of the materials can be increased by driving the materials to be stirred through rotation of the dispersion assembly; and on the premise that only one servo motor works, the purposes of wall sweeping of the kettle body and material dispersing of the dispersing assembly can be completed, so that the purposes of improving the material preparation rate and reduc
