Typically a slurry of 65% clay and 35% water is made (only possible if deflocculated) and ball milled, then dewatered (using filter presses, spray driers, etc) to make powder or pellets. In addition, materials will melt or go into solution in the melting glaze significantly better or sooner if they are ground finer.
After ball milling the tapes are cast. The bulk anode is composed of three tape layers. The g/cell numbers in Table 2 include materials masses for the three bulk anode tapes combined. The wet cast slurry passes through a drying hood in which the solvents evaporate, leaving the flexible tapes. The six tapes are stacked and then bonded together
