ABSTRACT:
A method and apparatus for making electrode material from high hardness active electrode alloy powder are disclosed. In one embodiment, the method involves feeding the powder onto a carrier web, aligning a mesh or screen substrate with the carrier web, and compacting the powder and mesh in a series of roller mills. The carrier is removed after it has passed through the first roller mill, and the remaining green electrode web is passed through the second roller mill and into a sintering furnace. After sintering and cooling, the web is calendared, and then is wound on a take-up reel. The furnace provides a substantially water and oxygen-free argon-hydrogen atmosphere for sintering which discourages web oxidization at the elevated sintering temperature. A loss-in-weight feeder can be used to accurately deposit the desired amount of active material on the carrier web.
