PCT No. PCT/AT94/00128 Sec. 371 Date Mar. 15, 1996 Sec. 102(e) Date Mar. 15, 1996 PCT Filed Sep. 14, 1994 PCT Pub. No. WO95/08198 PCT Pub. Date Mar. 23, 1995The invention concerns a method for producing a nondetachable, fluid-tight, and gastight connection between a plate stack (1) and a plate-shaped lateral component (3) of an electrochemical battery, and for spacing this plate stack (1), which is comprised of successive, thin-walled electrode plates with separator plates (4) disposed between each of them; the lateral component (3) is comprised of electrically non-conducting material. According to the invention, the lateral component (3) is guided spaced apart from and parallel to the respective face ends (5) of the electrode plates and separator plates (4) of the plate stack (1). Then the region of the face ends (5) and the side of the lateral component (3) oriented toward the plate stack (1) are simultaneously exposed to a temporary surface heating until they reach melting temperature and are then pressed against each other until the material cools.
