Granulated lead oxides with teflon

Patent ·
OSTI ID:6164677
An improvement in the production of tube electrodes for lead storage batteries comprising mixing a small amount (0.1 to 3 weight percent) of polytetrafluoroethylene (Ptfe) with lead powder, the mixture is heated and shear stresses are applied thereto sufficient to convert substantially all of the ptfe in the mixture to fibrous form and to form a non-powdery dough. The dough is then granulated and the doughy granules about 100 mu to 500 mu in major dimension are used for filling tube elctrodes a lead-acid storage battery.
