Separator for storage battery
Patent
·
OSTI ID:6692684
In the electrolyte space between the positive and negative electrode plates of a storage battery, there are inserted separators made of a porous plate which has pyramid-shaped protrusions and depressions formed on both sides. The protrusions, distributed in a grid-like pattern, abut with their tips against the electrode plates and provide accurate plate spacing. Between the protrusions, the separator provides pass-like passages which form channels extending along the separator surface, for the removal of gases from the electrolyte space.
