Patent

CA 2309495

A miniature galvanic cell, preferably a zinc-air cell, employing a two-part housing (2, 34) and a sealing gasket (18) comprises a current collector (30) that extends from one of the housing parts, preferably a flanged cup (34), through an opening (28) in the gasket (18) into the electrode material (38). The gasket material (18), preferably a plastic material, extends over the internal surface of at least one of the housing parts (34) and over a portion of the current collector (30), to expose a low area current collector surface to the electrode material (38), thus preventing or minimising the formation of gases, such as hydrogen, on the current collecting surface. A gasket for use in such a cell and a process for producing such a cell are also disclosed.

L'invention concerne une pile galvanique miniature, de préférence une pile zinc-air. La pile, qui comprend un boîtier en deux parties (2, 34) et un joint d'étanchéité (18), comporte un collecteur de courant (30) qui part d'une partie du boîtier, de préférence une coupelle à collerette (34), traverse un orifice (28) formé dans le joint (18) et pénètre dans le matériau électrode (38). Le matériau du joint (18), de préférence un matériau plastique, recouvre la surface interne d'au moins une partie du boîtier (34) et une partie du collecteur de courant (30), de façon à exposer au matériau électrode (38) une petite surface active du collecteur. Cette configuration empêche ou minimise la formation de gaz, tels que l'hydrogène, sur la surface collectrice de courant. L'invention concerne également un joint d'étanchéité pour ladite pile et un procédé de fabrication de celle-ci.
