Abstract
A method of extruding an electrode, batch material, particularly a zinc or nickel, electrode material, and an extruder assembly for extruding the material, are described. The method and extruder are designed to produce a low compaction of the material and low, back pressure, whereby working of the batch material is limited.
Claims10
A method of extruding a zinc or nickel, electrode material which comprises mixing a homogeneous batch of raw materials composed of a source of zinc or nickel and also containing, as an additive, essentially unfibrillated polytetrafluoroethylene (PTFE), feeding the batch to an extruder, conveying the batch material through a first portion of the extruder, then generating a controlled degree of fibrillation, conveying the batch through a second portion of the extruder to a forming member and extruding the batch material through the forming member.
