Abstract
A method for leak-testing synthetic separators for interleaved planar electrodes is described. The method includes installing the separator such as a diaphragm or membrane about the electrodes to create an enclosed chamber within the separator, supporting the electrodes from a supportive cell housing, pressurizing the created chamber to a predetermined pressure with a gas, slowly filling the housing with a liquid to a level above the separator and observing the separator during the filling operation to determine if leaks are present in the separator.
