NOVELTY - An electrochemical cell includes a separator forming a lining on an interior surface of a cavity of an electrode. The separator has a free standing reinforced edge forming an interface between the electrodes. The reinforced edge includes a reinforcing material that provides structural support to the separator after the separator has absorbed the electrolyte.    USE - Used as an electrochemical cell e.g. as a battery for flashlights, radios or cameras.    ADVANTAGE - The reinforced edge serves to contain fragmented pieces from one of the cell's electrodes that may become dislodged when the cell is dropped, thus preventing the formation of an internal short circuit.    DETAILED DESCRIPTION - An electrochemical cell comprises:    (i) a container with an open end, a closed end and a sidewall;    (ii) first electrode (50) defining a cavity with an interior surface;    (iii) electrolyte within the container and in contact with the first electrode;    (iv) a separator (20) forming a lining on the interior surface (56) of the cavity;    (v) a second electrode (60) within the separator lined cavity; and    (vi) closure assembly (70) secured to the open end of the container.    The separator comprises a free standing reinforced edge which extends beyond the first electrode toward the open end of the container and forms an interface between the electrodes. The reinforced edge includes a reinforcing material which provides structural support to the free standing reinforced edge of the separator after the separator has absorbed the electrolyte.    An INDEPENDENT CLAIM is also included for manufacturing the above electrochemical cell by providing a strip of separator, coating the edge of the separator with a reinforcing material, coiling the coated strip to form a tube comprising non-coated portion and a coated reinforced edge, providing a container having an open end and comprising a first electrode defining a cavity, inserting the coiled tube into the cavity, inserting a second electrode into the tube defined by the coiled separator, and closing the container by securing a closure assembly to the open end of the container.
