LAMINATED LEAD ALLOY STRIP FOR BATTERY GRID APPLICATION AND ELECTROCHEMICAL CELLS UTILIZING SAME

摘要

A laminated lead alloy strip is suitable for full-charge / discharge cycle grids, as well as for conventional lead-acid battery grids. A thin layer of antimonial lead alloy is rolled on the sides of a strip of lead-calcium-tin alloy. The inner layer provides good mechanical strength, while the outer layers provide the electrochemical properties necessary for long discharge time in full charge / discharge cycle batteries. The invention relates to methods of manufacturing and using this strip as expanded grid material in electrochemical cells or accumulators.
