Work an FMEA Line for Separator Shrinkage

A separator supplier passes datasheet review, but the team has not evaluated edge shrinkage after realistic hot storage and assembly stress. FMEA row: function, failure mode, cause, effect, control, action Writing separator issue as the failure mode hides the mechanism and makes the action impossible to audit. Function State the job: maintain electronic isolation between electrodes while allowing ion transport. A failure mode must be tied to a lost function. Without the function, the row becomes a component complaint instead of risk analysis. Failure mode and cause Write the mode as separator edge shrinkage reducing overlap margin; list causes such…
