New Mechanically Rechargeable Zinc-Air Batteries.

Abstract

This report describes the design, development and testing of new mechanically rechargeable zinc-air batteries. Following research and development of a low cost silver-mercury cathode catalyst, prototype battery tests were conducted. Cycle life tests at 3.5 amperes indicated satisfactory performance through at least 26 cycles when this test was terminated for the final hardware build. The cathode bi-cell design utilized the 75 AH plastic frames which were cut down in height and width. Woven-zinc anodes were tested during the program, but were found to operate at reduced voltage and efficiency. The final anode design was a dry pressed composition of zinc, KOH, and HgO and indicated a very good efficiency at 3.5 amperes. Final batteries were delivered in fabricated plexiglass cases with 22 series - connected cells. Discharge tests were conducted on nine (9) of the ten (10) delivered batteries.
