Stirrer for lithium battery material drying device

The invention discloses a stirrer for a lithium battery material drying device. The stirrer comprises a roller and a stirring shaft. The stirring shaft is arranged in the roller. The stirrer is characterized in that the roller comprises an inner roller body and an outer roller body. A heating space is clamped between the inner roller body and the outer roller body, and a heating coil is arranged in the heating space and wound around the outer roller wall of the inner roller body. Multiple baffles are arranged on the stirring shaft and arranged in the circumferential direction of the stirring shaft in sequence. The section of each baffle is in an arc shape, and a through groove is formed in the side, close to the stirring shaft, of each baffle. According to the stirrer, the heating space isclamped between the inner roller body and the outer roller body, then the surface, making contact with the roller, of a material can be fully dried, and therefore the situation that the material is fully dried is guaranteed,
