The invention belongs to the technical field of lithium ion batteries, particularly relates to a method for testing a button type half battery made of a lithium ion battery electrode material, and belongs to the field of lithium batteries. The technical scheme adopted by the invention is as follows: the method comprises the processes of manufacturing a pole piece and assembling a button type half cell, namely putting a clean base material on an infrared flat plate coating machine, uniformly coating slurry on the base material, drying the pole piece by the coating machine, baking by a vacuum oven to remove moisture, cutting off a blank base material, sequentially rolling the pole piece once at roller gaps of 50mu m, 40mu m and 30mu m of a double-roller machine, and assembling the button type half cell after the pole piece is rolled once at the roller gaps of 50mu m, 40mu m and 30mu m of the double-roller machine. Making the pole piece into a circular pole piece, pasting the circular pole piece on a gasket by using a small amount of conductive adhesive, drying the circular pole piece to serve as a pole piece sheet, placing the negative pole shell of the button-type half cell on a flat operation table in a closed environment, and putting an elastic sheet into the operation table; after six drops of electrolyte are added, a gasket and a pole piece are added, then three drops of electrolyte are added to wet (increase) a pole piece dressing, a diaphragm is attached to the pole piece, a lithium piece is placed and slightly pressed, a positive pole shell is covered, the lithium piece is placed in a sealing machine to be sealed at the pressure of 800 psi, and the button type half-cell sample for material testing is obtained.
