Abstract
An electrolyte reservoir plate is formed in a papermaking process. Graphite powder, reinforcing fibers, cellulosic fibers, and a thermosetting resin are mixed with a liquid to form a slurry and showered onto a screen to form a planar sheet which is dried to form paper. The paper is cut into the desired size and is lay-up with main sheets 4 and edge strips 6. The lay-up is laminated with pressure and heat, carbonized, and graphitized to form an electrolyte reservoir plate.
