Metal-air battery with an extended service life
First Claim
1. A battery comprising at least a first metal-air cell assembly and a second metal-air cell assembly electronically connected in parallel, whereinsaid first cell assembly comprises a first casing with a first controllable air vent thereon and at least a first metal-air cell inside said first casing, wherein said first controllable air vent is closed during a battery storage period and is opened in response to a first programmed signal in order to allow outside air or oxygen to enter said at least a first metal-air cell through said first air vent to activate operation of said first metal-air cell assembly;
- said second cell assembly comprises a second casing with a second controllable air vent thereon and at least a second metal-air cell inside said second casing, wherein said second controllable air vent is closed during a battery storage period and is opened in response to a second programmed signal in order to allow outside air or oxygen to enter said at least a second metal-air cell through said second air vent to activate operation of said second metal-air cell assembly; and
control means for sending programmed signals to open up said at least first and second vents at the same time or at different moments of time in a programmed fashion.

Abstract
A battery comprising a control means and a plurality of metal-air cell assemblies that are electronically connected in parallel. Each cell assembly comprises a casing with a controllable air vent thereon and at least a metal-air cell inside the casing. The controllable air vent is closed during a battery storage period and is opened in response to a programmed signal in order to allow outside air or oxygen to enter the assembly through the air vent to activate the operation of the corresponding cell assembly. The control means, preferably including a sampling unit, a power control unit and a logic control unit, is capable of sensing the battery output voltage and sending programmed signals to open or close up the air vents at the same time or at different moments of time in a programmed fashion.
