METHOD FOR PRODUCING TUBULAR-PLATE ELECTRODES OF ALKALINE CELL Russian patent published in 1995 - IPC

FIELD: electrical engineering. SUBSTANCE: method involves sintering of porous base, its impregnation with active materials, molding and blanking of electrodes, making of projections on current lead, and its soldering to base. Projections on current lead are made in the form of bosses. The latter are placed in holes drifted in base. Large-base area of boss to hole area ratio is 1.02-2.8. Then current lead is fixed in holes through bosses and holding strap is fitted on opposite side and welded to bosses. EFFECT: simplified procedure and improved reliability of fixation. 5 dwg
