Abstract:
A method for manufacturing a device for evaluating the effectiveness of can coatings intended for use in a primary alkaline battery cell, said method comprising the steps of:forming a cup and a test disk from a material, with the can coating applied to the interior surface of the cup and to one surface of the disk; forming a lightly compacted disk of a simulated cathode mix in the cup; placing the test disk onto the lightly compacted cathode mix such that the coated side of the metal disk is in electrical contact with the cathode mix disk, an opposite surface of the test disk is not in electrical contact with the cathode mix disk and the test disk is not in direct electrical contact with the cup; compacting the contents of the cup tightly to create intimate electrical contact between the cathode mix and the test disk and the cathode mix and the interior surface of the cup; forming a sealing cap from an electrically nonconductive material atop the test disk and the cathode mix in the cup to maintain the contents of the cup in a compacted state; and providing electrical contact to a portion of the test disk.
