Abstract:

The feasibility of using zinc-oxygen batteries for long-term discharges was investigated with the objective of attaining a one-year discharge lifetime and a five-year storage lifetime at uncontrolled temperatures. Zinc and oxygen electrodes were developed and used to construct zinc-oxygen cells for discharge testing. Cell lifetime was limited by premature oxidation of the zinc electrode due to corrosive chemical reactions set up by the nickel. The five- year storage requirement dictates the use of a reserve configuration with electrolyte kept in individual cell reservoirs during storage. Preliminary designs of the electrolyte storage and activation systems were done based on the electrode and cell designs developed.
