A pole piece slitting method comprises the following steps: the method is characterized in that: when a battery pole piece is cut, the lifting mechanism 2 drives the upper cutting mechanism 3 to move downwards, the upper cutting mechanism 3 is matched with the lower cutting mechanism 4 to cut the battery pole piece, after the battery pole piece is cut off, the lifting mechanism 2 drives the upper cutting mechanism 3 to move upwards, and the cut battery pole piece falls from the feed opening 11 after passing through the feed gap 411; specifically, according to different specifications of the battery pole pieces, the upper spacing adjustment assembly 33 of the upper slitting mechanism 3 adjusts the spacing between the two upper cutter blades 34 by driving the two upper cutter holders 32 to move in opposite directions or move in opposite directions, and the lower spacing adjustment assembly 43 of the lower slitting mechanism 4 adjusts the spacing between the two lower cutter blades 44 by driving the two lower cutter holders 42 to move in opposite directions or move in opposite directions so as to adapt to the specification of the battery pole pieces to be cut at present, after the adjustment is completed, the battery pole pieces are placed on the two pole piece support plates 45 of the lower slitting mechanism 4 and located above the blanking notch 411, and by arranging the pole piece support plates 45, the wrinkle of the battery pole pieces can be avoided, the yield of the cut battery pole pieces is ensured, then the lifting mechanism 2 drives the whole upper slitting mechanism 3 to perform downward probing through the upper bearing plate 31, at this time, the two upper cutter blades 34 are respectively matched with the two lower cutter blades 44, the battery pole pieces are cut, after the cutting of the battery pole pieces is finished, the upper cutting mechanism 3 moves upwards, at the moment, the battery pole pieces between the two lower cutting blades 44 fall into the feed opening 11 of the rack 1 through the feed gap 411 under the dead weight, then fall from the feed opening 11 and are transferred out of a working area, so that the cutting work of the battery pole pieces is finished, and the process is repeated so as to continuously cut the battery pole pieces; for battery pole pieces with different specifications, the cutting requirements of the battery pole pieces with different specifications can be met only by adjusting the distance between the upper cutter set and the lower cutter set through the upper distance adjusting assembly 33 and the lower distance adjusting assembly 43.
