Abstract:
A battery comprised of a generally rectangular electrochemical cell that has two battery leads attached to current collectors extending from one side thereof. A package formed from a sheet laminate has a cavity formed therein that defines an opening for receiving the cell and portions of the leads. A flange extends around the opening. A cover overlays the cavity and the flange. The cover is joined to the flange and forms a seal that hermetically seals the electrochemical cell within the cavity. The package has two, non-rectangular corners. The cover and the flange in the vicinity of the corners are shaped to allow the flange to be bent along the at least three sides in a manner wherein the flange is positioned adjacent the three sides, but the flange is not tucked or overlapped onto itself at the two, non-rectangular corners.
