Abstract:
A method of making a cathodic electrode assembly for an electrotransport device for delivering or sampling an agent through a body surface, the method comprising:forming a solid silver halide cathodic electrode from silver halide particles, said electrode comprising at least 95 vol. % silver halide, the electrode having an organic material content of less than 1 vol. % and being substantially free of any electrically conductive filler which absorbs cathodic electrolyte reservoir formulation materials; wherein said electrode has a discharge capacity of at least 500 mAhr/cm3; and providing a cathodic electrolyte reservoir wherein said electrolyte reservoir is positioned adjacent to and in ion transmitting relation with the electrode, the electrolyte reservoir while in use being positioned intermediate the electrode and the body surface, and in ion transmitting relation with the body surface.
