Method and apparatus for making electrode material from high hardness active materials.

摘要

A method and apparatus for making electrode material from high hardness active electrode alloy powder involve feeding the powder onto a carrier web (12), aligning a mesh or screen substrate (50) with the carrier web, and compacting the powder and mesh in a series of roller presses (60, 70). The carrier (12) is removed after it has passed through the first roller press, and the remaining green electrode web is passed through the second roller press and into a sintering furnace (90). After sintering and cooling, the web is calendered (116,118), and then is wound on a take-up reel (120). The furnace provides a substantially water and oxygen-free argon-hydrogen atmosphere for sintering which discourages web oxidation at the elevated sintering temperature. A loss-in-weight feeder (30) can be used to deposit accurately the desired amount of active material on the carrier web.
