  • Method of determining electrolyte leakage in hermetically sealed electrochemical cell
    Patent number: 4135384
    Abstract: Hermetically sealed electrochemical cells are checked for electrolyte leakage by immersing the completed cell in a liquid medium such as chemically pure deionized water and monitoring the medium for electrical and/or chemical changes that would be caused therein if the electrolyte were leaking from the cell. Such changes could be determined by measuring the electrical conductivity of the liquid medium, the ion concentration, or the pH.
