METHOD FOR INSPECTING CELL

摘要

A method for inspecting a cell (A) having: an electrode stack (3) in which a positive electrode (1A), a separator (2), and a negative electrode (1B) are stacked; a positive electrode terminal (5A) connected to the positive electrode (1A); a negative electrode terminal (5B) connected to the negative electrode (1B); and a laminate film (4) as an exterior component including a metal layer (4a) and a resin layer disposed on the inner side of the metal layer (4a), the electrode stack (3) and an electrolytic solution being accommodated and sealed in the interior of the laminate film in a state in which one end of both the positive electrode terminal (5A) and the negative electrode terminal (5B) protrudes to the exterior. The method includes a step for determining voltage resistance between the metal layer (4a) and the positive electrode terminal (5A) and/or the negative electrode terminal (5B), in a state in which the electrode stack (3) is accommodated in the laminate film (4) and the electrolytic solution has not yet been poured in. It is thereby possible to effectively detect the defects of electrical short circuiting.
