Patent ·
OSTI ID:7197991
A rechargeable silver--zinc electric storage cell is described which comprises a casing enclosing a silver electrode and a zinc electrode, a separator comprising an imperforate semi-permeable membrane disposed between the electrodes, and an electrolyte. The membrane is sealed to the casing so that the only ion path between the electrodes is through the membrane. The imperforate semi-permeable membrane comprises a laminate of plies of semipermeable oriented foil material bonded together with the electrolyte, with some of the plies arranged cross-wise relative to another ply of the membrane.
