Abstract: An improved method of affixing spheres 4 to a foil matrix 2 is described herein. First, a cell sandwich 32 is prepared. This cell sandwich 32 includes spheres 4 mounted on a foil matrix 2 which are disposed between upper and lower pressure pads 34 and 36. The cell sandwich 32 is then heated (e.g., to about 530.degree. C.). The spheres 4 are then affixed to the foil matrix 2 by directing the cell sandwich 32 through a roll press 48 which compresses the heated cell sandwich 32.
