Abstract

Non-sintered PTFE-bound electrodes for alkaline storage batteries are made by coagulating polytetrafluoroethylene (i.e. PTFE) particles from an aqueous dispersion thereof to form a gelatinous coagulum, mechanically dispersing the coagulum in water such that the coagulum is subdivided into small, sticky clots of PTFE particles which are suspended in the water, mixing the suspension with comminuted electrochemically active material to form a slurry of active material and active-material-coated clots, filtering the slurry to separate the solids (i.e. as a filter cake) therefrom, integrating (e.g. sandwiching) an electrically conductive current collector with the filter cake, compressing the thusly formed composite, and drying the compress.
