Abstract
An improvement in the production of plate type electrodes for use in lead storage batteries from a dry lead powder mixture is disclosed. The lead powder is mixed with a small amount (0.1 to 3 weight percent) of polytetrafluoroethylene (PTFE) powder, the mixture is heated and treated to convert substantially all of the PTFE into fibrous form. The mixture is applied to an electrode grid under conditions whereby a coherent, unitary structure is formed. A hot liquid (e.g., water) may be added to the mixture to form a paste.
