A lithium-ion battery for a forced internal short-circuit test, comprising a lithium-ion battery core, a short-circuit metal piece, a positive pole tab, a negative pole tab, and a sealing packaging film. The lithium-ion battery core includes a positive pole, a negative pole and a diaphragm spaced between the positive pole and the negative pole. The lithium-ion battery core has been removed from the outer packaging and is fully charged. The short-circuiting metal piece is entangled in the lithium-ion battery cell. The positive pole tab and the negative pole tab are welded on the lithium-ion battery core and electrically connected to the positive pole and the negative pole respectively. The sealed packaging film seals the lithium-ion battery core and vacuumizes it, so that the short-circuit metal parts form convex marks on the sealed packaging film. The above-mentioned lithium-ion battery used in the forced internal short test is sealed and packaged with a sealed packaging film to ensure that the electrolyte does not leak. At the same time, after vacuum treatment, the short-circuit metal parts form a convex mark on the sealed packaging film, and the placement position is relatively obvious. . The invention also provides a preparation method of the lithium ion battery for the forced internal short test.
