LOW TEMPERATURE BATTERY (NEW MAGNESIUM ANODE STRUCTURE).

Abstract

The physical parameters of the 'D' size Balaguer cell structure were evaluated. Different separators, reinforcements and closures were tested. Investigations of shelf life, cell reproducibility and low temperature performance consisted of 18 programs involving various design modifications and combinations of cell components. Eight screening programs were undertaken to investigate the anode potting of the cell. Cleaning of the anode after forming with Dow 21 minimized the pitting. The elimination of copper contamination, which had caused serious shelf life problems, was accomplished by modifications in the method of forming the cup. A plastic closure was developed which prevents electrolyte leakage from the cell. A seamless steel jacket in combination eith the rope tack masking tape improved the shelf life of the cell to a high degree and virtually eliminated the problem of cell expansion during discharge. It has been demonstrated that present techniques and cell fabrication procedures provide cells with a high service level, an excellent shelf life, and a high degree of uniformity within and among various cell lots. Initial investigations necessary to establish the design parameters required for the construction of an AA size magnesium cell utilizing the Balaguer structure were conducted, and the feasibility of making this cell size has been established.
