Tightly sealed galvanic element

Patent ·
OSTI ID:5447865
A galvanic element, particularly of the button-cell type with hermetically sealed housing of plastic, uses electrode take-off conductors for each polarity positioned in labyrinthine shape inside the housing wall which is formed of two firmly connected layers. The ends of each labyrinthine take-off conductor respectively contact a connector terminal on the inside and a connector terminal on the outside of the housing wall. This provides an exceptionally long creepage path for the hydroxide electrolyte.
