Battery pole piece stripping force test tool and test method thereof

The invention relates to the technical field of lithium ion batteries, in particular to a battery pole piece stripping force testing tool and a testing method thereof.The testing tool comprises a base connected with a pull-down machine; the workbench is movably connected to the base, the workbench can move relative to the base, and the workbench is used for being connected with a to-be-tested piece; the guide part is located between the upper drawing machine and the workbench, a preset gap is formed between the guide part and the workbench, and when the upper drawing machine pulls the base film to move in the first direction, under the action of the guide part, the workbench at least can move towards the side away from the guide part in the second direction relative to the base; the base film of the stripping part from the substrate can keep moving in the first direction, and the included angle between the base film of the stripping part and the substrate is kept at 90 degrees. According to the method and the
