The invention discloses an electrification crushing combining device for crushed lithium ion power lithium batteries. The structure comprises a raw material hopper, a crusher protective housing, a crushing-separating device for a lithium battery, an external power supply, a support bracket, an anti-skid base plate, the bottom end of the raw material bucket is fixedly connected to the top end of the crusher protective shell by welding and is perpendicular to the crusher protective shell, the crushing-separating device for a lithium battery is installed inside the protective housing of the crusher in an embedded mode, one end of the external power supply is installed on the side of the protective housing of the crusher in an embedded mode, the bottom of the protective housing of the crusheris fixedly connected to the top end of the support frame by welding and the protective housing of the crusher is perpendicular to the support frame. According to the electrification crushing combiningdevice for crushed lithium ion power lithium batteries of the present invention, a magnetic pole classification design is adopted, and the effective material of a lithium battery is effectively distinguished from waste material and collected after the lithium battery is fully crushed, so that the treatment step of waste lithium batteries is simple, the time consumed is short, and the collection degree of extracts is high.
