Patent ID: 7157171

Claim:
An actively controlled battery with a programmed-timing actuation capability, said battery comprising: (a) a first metal-air cell assembly and at least a second metal-air cell assembly electronically connected in parallel, wherein said first cell assembly comprises at least a first metal-air cell comprising a first active anode enclosed in a first anode compartment, an air cathode, a separator separating said anode from said cathode, a first reservoir containing an electrolyte fluid therein, and a first controllable fluid valve being in flow communication with said first electrolyte fluid reservoir on one side and in control relation to said first anode compartment on another side; said first fluid valve being closed during a battery storage period and being opened, at the first use of said battery, to allow said electrolyte fluid to enter said first anode compartment to come in contact with said anode therein for activating an operation of said first metal-air cell assembly; and said second cell assembly comprises at least a second metal-air cell comprising a second active anode enclosed in a second anode compartment, a second air cathode, a second separator separating said second anode from said second cathode, a second reservoir containing an electrolyte fluid therein, and a second controllable fluid valve being in flow communication with said second electrolyte fluid reservoir on one side and in control relation to said second anode compartment on another side; said second fluid valve being closed during a battery storage period and being opened in response to a programmed signal to allow an electrolyte fluid to enter said second anode compartment to come in contact with said second anode therein for activating an operation of said second metal-air cell assembly; and (b) control means in control relation to at least said second cell assembly for sending programmed signals to open up at least said second controllable valve in a programmed fashion.
