The present invention relates to the technical field of
coating processing and production of hard carbon negative
electrode materials, and in particular to an ultra-high performance negative
electrode material
coating system, comprising a
coating kettle, a circulation mechanism, an
extrusion dispersion mechanism and a dispersion barrier net; the circulation mechanism is connected to a
discharge port at the bottom of a cavity and a top opening of a hollow flow channel on a stirring
paddle, and the circulation mechanism circulates the negative
electrode material in the cavity into the flow channel; the
extrusion dispersion mechanism is installed on the upper part of the stirring
paddle, the
extrusion dispersion mechanism is located in the cavity, an extrusion bin of the extrusion dispersion mechanism is connected to the flow channel, when the stirring
paddle rotates, the pressure in the extrusion bin fluctuates, and the negative
electrode material flowing out of the flow channel is squeezed, so that the negative
electrode material is ejected from the extrusion bin; the dispersion barrier net is arranged in the cavity, the dispersion barrier net is rigidly arranged, and the dispersion barrier net flattens the negative
electrode material ejected by the extrusion dispersion mechanism, and filters out excess molten coating material on the surface of the negative electrode material.
