✦ Synopsis

A mechanism for electrolyte creep is presented, explaining the high pressure that the electrolyte film can generate in the sealing zone of an alkaline cell. Also, the drop formation at the film front in creep experiments is explained. We assume that alkali atoms, underpotential deposited from the continuous electrolyte film, diffuse a short distance along the metal surface and again react with air and humidity to form a drop of electrolyte. The velocity of the whole film movement depends on the equivalent conductivity of the alkali ions in the continuous electrolyte film.
