SEALING STRUCTURE FOR AN ALKALI BATTERY

摘要

After a negative electrode current collector (10) has been inserted into an insertion hole (28a) therein, a resin sealing element (28) and negative electrode terminal plate (12) are successively inserted into an aperture (1a) of a battery casing (1), and the aperture rim of battery casing (1) is then bent inwards and crimped to seal aperture (1a) of battery casing (1). Sealing element (28) is accommodated within battery casing (1) in an arrangement facing negative electrode terminal plate (12), with resin injection gate (28c) corresponding to resin injection port (27a) of metal molds (22 - 24) during resin molding thereof positioned at the aperture end of battery casing (1).
