<P>PROBLEM TO BE SOLVED: To provide an evaluation method of an electrochemical element for reproducing a pseudo short-circuit by metal powder, and quantitatively evaluating durability of an insulation layer laminated on an electrode for the electrochemical element. <P>SOLUTION: The evaluation method of the electrochemical element includes a needle insertion process in which a load is impressed on a needle 4 equipped with a tip part 4a made of a conductive member, the tip part 4a is inserted into the insulation layer 12 from the surface of the insulation layer 12 laminated on the electrode 10 for the electrochemical element, and is made to reach the electrode 10 for the electrochemical element. In the needle insertion process, the load as well as an electric resistance between the tip part 4a and the electrode 10 for the electrochemical element is measured at time lapses. <P>COPYRIGHT: (C)2009,JPO&INPIT |
