This utility model discloses an automatic production system for lithium batteries, which comprises a twin-screw extruder, on which a feeding mechanism for feeding lithium battery materials is arranged; a scraper filter is arranged at one end of the twin-screw extruder and is communicated with the inside of the twin-screw extruder through a first pipeline, and the other end of the scraper filter is connected with a permanent magnetic iron remover for removing impurities from lithium battery materials. The device realizes the conveying, shearing and meshing of positive and negative electrode materials of lithium batteries in the twin-screw extruder through the reasonable arrangement of each unit element inside the co-rotating twin-screw extruder, and then carries out vacuum defoaming and exhaust; finally, a series of processes such as filtration, demagnetization, defoaming and conveying of the slurry are performed, which effectively controls the dispersion uniformity of the slurry and improves the dispersion effect of lithium ions in the slurry. The system has a high degree of automation and low energy consumption.
