Abstract
A spray method of applying liquid adhesive to surfaces of components of an electrochemical cell. The adhesive is applied by spraying through a nozzle, preferably activated by a piezoelectric transducer. The nozzle can be an elongated resilient tube terminating in an outlet opening. The adhesive is preferably sprayed in a pulsed stream of droplets. The liquid adhesive is desirably dispensed in fine droplets at a rate of between about 500 and 5000 droplets per second. The method is effective in applying adhesive to narrow width or difficult to reach surfaces of cell components in a precise, consistent and reproducible manner. In a specific application the adhesive can be applied to the narrow recessed step surrounding the terminal portion of the cathode casing of a zinc/air button cell. In such application the adhesive provides a tight seal between the cathode casing and cathode assembly, thereby preventing leakage of electrolyte from the cell.
