Abstract : A study has been made of the methods by which silver is transported from the silver electrodes in silver-alkaline batteries. This study has been made using radioactive silver tracers as well as by straight analytical techniques. This transport is due primarily to diffusion. Various kinds of separator materials have been tested with respect to reactivity with dissolved silver oxides as well as with respect to effectiveness in preventing the transport of silver in a working silver-alkaline battery. Generally, effectiveness in preventing transport is due to reaction with the silver oxide dissolved in the potassium hydroxide electrolyte. Two screening tests have been devised for testing the effectiveness of a given separator material in preventing the transport of silver. (Author)
