The invention provides an in-situ test mold of a battery cell and a method for performing neutron test on the battery cell, and relates to the technical field of neutron test of batteries. The in-situ test mold comprises an insulating sample shell used for placing a battery cell a first electrode piece connected with a test device and a second electrode piece connected with the test device connecting; the insulating sample shell is provided with a sample cavity, and the sample cavity penetrates through the first end and the second end of the insulating sample shell; a first electrode column of the first electrode piece is inserted into the sample cavity through the first end so as to extrude the battery cell and conduct the positive electrode of the battery cell; and a second electrode column of the second electrode piece is inserted into the sample cavity through the second end so as to extrude the battery cell and conduct the negative electrode of the battery cell. The in-situ test mold can simulate the in-situ operation state of the battery so as to carry out neutron diffraction test and neutron imaging test on the battery, and can overcome the problem of interfering neutron diffraction signals or absorbing neutrons.
