The report describes the work performed during a one-year program to develop a high rate, primary zinc-air battery. The major portion of this report is concerned with the battery testing, and activated storage studies. Five-cell batteries of the final design were fabricated and discharged at the maximum rated current of 2.5 amps at ambient temperatures. At 0F, 70F and 125F the battery delivered 16.7, 16.2 and 11.5 amp-hours respectively. The battery was also evaluated at the low rate 0.3 amp requirement established for this battery. Anodes activated and stored at 125F for more than six months exhibited an 18 capacity loss upon discharge. Bicells activated and stored for two months at room temperature, and one month at 125F, did not indicate significant capacity loss when discharged. A summary of the component development and battery fabrication completed in the first three quarters is also included. The final optimized battery yielded a materials cost of 0.017 per watt-hour and an energy density of 113 watt-hours per pound. Author
