A METAL-AIR BATTERY HAVING IN-SITU GENERATABLE ELECTROLYTE

摘要

A battery comprising a consumable anode (22); a gas-diffusion cathode (24); a non passivated surface-destroying aqueous medium in contact with the anode and cathode; a housing (12) enclosing the anode, cathode and medium; an additive (32) contained within a medium-impermeable chamber (30) separated from but receivable by the medium upon activation to effect mixing of the additive with the medium to provide an electrolytic mixture to effect electrical contact between the anode and cathode; and activation means (31) to effect said activation. The battery provides an extended shelf-life prior to activation by reason that the anode is not corroded by the electrolyte. The battery is of particular use in portable cell-phones, computers, video cameras and players.
