The invention relates to the technical field of processing technologies for battery materials, and discloses a processing technology of graphene battery materials. The processing technology of the graphene battery materials comprises a grinding box, wherein a feeding hopper is arranged at the top of the grinding box, a rotating rod is arranged in the middle of one front side of the grinding box, grinding cylinders are arranged in the middle of the outer surface of the rotating rod, first bevel gears are arranged at the other end of the rotating rod, a movable rod is arranged in the middle of the front surface of the grinding box, a second bevel gear is arranged on the outer surface of the movable rod, and a transmission motor is arranged at the bottom of the front side of the grinding box.According to a processing device of the graphene battery materials, a driving motor and a stirring head are cooperated with each other, the battery materials inside a mixing box are more sufficientlymixed, a sliding chute, a baffle plate and a spring are mutually cooperated. Therefore, the battery materials mixed inside the mixing box are discharged conveniently to solve the problem of taking more time to completely discharge the battery materials out of the mixing box, so as to improve the discharging efficiency of the battery materials.
