The electrochemical system used in this battery consists of silver and zinc electrodes. The electrolyte is a concentrated aqueous solution of potassium hydroxide. The separator system is proprietary to Yardney and is designed to assure excellent capacity maintenance after extended cycle life. The silver electrode is made from fine silver powder rolled onto a silver expanded metal grid. The zinc electrode is made from zinc oxide powder rolled onto a perforated copper grid. The separator system is wrapped around the positive electrode. The manufacturing processes used on these plates yield electrodes that offer strength and plate integrity sufficient to meet the environmental and mission requirements. The BB519 and BB462 Batteries have successfully demonstrated that a 16-pound silver--zinc battery yielding 25 Ah can be integrated into the standard line configuration. The addition of a high rate battery to the standard line offers extended capability to man-pack applications. (GRA)
