Abstract
"VASO DE PRESSãO, CéLULA ALCALINA PRIMáRIA, E, MéTODO PARA FECHAR O ALOJAMENTO EXTERNO DE UMA CéLULA ALCALINA". é descrita uma célula alcalina que tem um alojamento plano, preferivelmente de forma cubóide. A célula pode ter um anodo compreendendo zinco e um catodo compreendendo MnO~ 2~. O alojamento pode ter uma espessura geral relativamente pequena, tipicamente entre cerca de 5 e 10 mm. Os conteúdos da célula podem ser supridos através de uma extremidade aberta no alojamento e um conjunto de tampa de extremidade inserido nele para selar a célula. Pode haver uma folga entre o separador e o catodo para inserção de eletrólito adicional. O conjunto da tampa de extremidade inclui um mecanismo de exaustão, preferivelmente um suspiro entalhado, que pode ser ativado quando a pressão de gás dentro da célula atingir um nível de patamar tipicamente entre cerca de 250 e 800 psig (1.724 X 10¬ 3¬ e 5.515 x 10¬ 3¬ Pascal manométrico). A célula pode ter um mecanismo de exaustão suplementar, tal como uma região soldada por laser, na superfície do alojamento que pode ser ativada a níveis de pressão mais altos."PRESSURE VASE, PRIMARY ALKALINE CELL, AND METHOD FOR CLOSING THE EXTERNAL ACCOMMODATION OF AN ALKALINE CELL". An alkaline cell having a flat housing, preferably cuboidal in shape, is described. The cell may have an anode comprising zinc and a cathode comprising MnO ~ 2 ~. The housing may have a relatively small overall thickness, typically between about 5 and 10 mm. The contents of the cell may be supplied through an open end in the housing and an end cap assembly inserted therein to seal the cell. There may be a gap between the separator and cathode for additional electrolyte insertion. The end cap assembly includes an exhaust mechanism, preferably a notched vent, which may be activated when the gas pressure within the cell reaches a plateau typically between about 250 and 800 psig (1,724 X 10¬ 3¬ and 5,515 x 10¬ 3¬ Gauge Pascal). The cell may have an additional exhaust mechanism, such as a laser welded region, on the housing surface that can be activated at higher pressure levels.
