Abstract
A method of screening a battery for failure mechanisms is provided. The method may include activating an electrochemical cell. Within 5 minutes to two hours of activating the cell, the open circuit voltage of the cell is measured over a period of time to determine a voltage versus time function. The cell is then screened for the presence of a failure mechanism by checking the voltage versus time function for a failure criteria.
