IMPROVED RM 'BUTTON' TYPE PRIMARY CELLS.
Abstract
The effective area of the depolarizer was greatly increased by reducing consolidation pressure on the so-called porous depolarizer. A number of barrier materials were investigated and found to improve the 50 C shelf life of SC-12 cells, which employed a CMC gelled electrolyte. Without a barrier between the depolarizer and the gel, liquefaction of the latter will occur after extended shelf periods. Sprayed Mg(OH)2 was particularly satisfactory as a barrier material. An extensive number of SC-6 cells were fabricated and tested. Studies on the effect of anode current density on cell performance were carried out. It was found that higher current densities resulted in greatest discharge life. Reasons for this phenomenon are discussed, with reference to similar results obtained through attempts to electropolish zinc.
