Abstract
An electrochemical cell includes an electrode (10) having a microporous polymeric substrate (12) upon which is deposited the first and second layers (18 and 22) of an electrochemically material. Disposed between said first and second layers of electrochemically active materials is a current collecting layer adapted to electrically couple the electrode with a battery cell can. Two or more of such electrodes (40 and 60) may be stacked one atop the other in order to affect a positive and negative electrode as used in conventional cylindrical cells.
